the Indian Buffet Process},
abstract = {We define a probability distribution over equivalence classes of binary ma- trices with a finite number of rows and an unbounded number of columns. This distribution is suitable for use as a prior in probabilistic models that represent objects using a potentially infinite array of features. We derive the distribution by taking the limit of a distribution over N × K binary matrices as K → ∞, a strategy inspired by the derivation of the Chinese restaurant process (Aldous, 1985; Pitman, 2002) as the limit of a Dirichlet-multinomial model. This strategy preserves the exchangeability of the rows of matrices. We define several simple generative processes that result in the same distri- bution over equivalence classes of binary matrices, one of which we call the Indian buffet process. We illustrate the use of this distribution as a prior in an infinite latent feature model, deriving a Markov chain Monte Carlo algo- rithm for inference in this model and applying this algorithm to an artificial dataset.},

The extent of separation between clusters obtained by SOM was examined by cross val- idation procedure using supervised neural networks for classification. A method is proposed for variable selection to reduce the ``curse of dimension- ality''. Six variables were chosen for cluster analysis. Additionally, principal components were computed using all the original variables and 6 components which accounted for a high percentage of variance was chosen for SOM anal- ysis. All these methods indicate 4 or 5 clusters. Further analysis based on the average profiles of the GRB indicated a possible reduction in the number of clusters.},

abstract = {OBJECTIVE: The aim of the study was to investigate whether weight, length, BMI (kilograms per meter squared), and head circumference at birth and their postnatal growth are associated with cognitive abilities at 56 months of age among infants born at term. PATIENTS AND METHODS: Our sample was composed of 1056 Finnish children born at term, (37 to 41 weeks) free of any major impairments. Weight, length, and head circumference were measured at birth and at 5, 20, and 56 months of age, and BMI was calculated. We assessed cognitive abilities by conducting tests of general reasoning, visual-motor integration, verbal competence, and language comprehension at 56 months of age. RESULTS: Firstly, for every 1 SD lower in weight or BMI at birth, general reasoning and/or visual-motor integration was >1.20 points lower, and for every 1 SD lower in length or head circumference at birth, abilities across all of the cognitive domains were >1.31 points lower. Second, for every 1 SD slower gain in weight or BMI from birth to 5 months, general reasoning and visual-motor integration decreased by >0.97 points; for every 1 SD slower gain in length from 5 to 20 months and from 20 to 56 months, respectively, visual-motor integration, and verbal competence and language comprehension decreased by >1.03 points; and for every 1 SD slower increase in head circumference from birth to 5 months and from 5 to 20 months, respectively, visual-motor integration and language comprehension decreased by >1.17 points. Third, tests for nonlinear relationships revealed that, in some cases, large body size and faster growth were also associated with lower scores in cognitive tests. CONCLUSIONS: Our findings suggest that, even within the range of children born at term, prenatal and postnatal growth in body size are associated with individual differences in cognitive abilities.},

title = {An assessment of full cross-validation},
abstract = {Full cross-validation was promoted as an alternative to regular cross-validation for nonlinear regression model selection in Bunke et al. (1998, 1999). In Droge (1995), simulations were performed to explore its performance for model selection in a polynomial regression context, finding mixed results at best. The poor performance of the method was not highlighted in later publications related to the method. In this work, we explore its performance for nonlinear regression models, which has not been evaluated previously. The method is attractive for use in situations where cross-validation methods are desired but estimation algorithms are not easily modified for missing observations or estimation can easily diverge when design points are removed, such as nonlinear regression. A simulation study is used to reinforce the poor performance of FCV for model selection in linear regression and to demonstrate that its problems extend into nonlinear regression models as well. For moderate sample sizes in linear regression, the problems with FCV seem to diminish but the protection of a larger sample size seems to disappear for the nonlinear regression models explored. This suggests caution in using FCV for model selection in general.},

This view appears to contradict a large portion of the memory literature that shows, over long intervals, remarkably accurate recall. A perspective, based on an elaboration of Underwood's attributes model of memory, is advanced which proposes that for all types of information both detailed and thematic attributes are stored. Consequently, the type of recall one sees, whether reconstructive or reproductive in nature, depends in part upon events that occur at the time of the request for recall. Two experiments using prose passages as stimulus materials with retention tested by free recall support this perspective. Subjects were treated identically until the test of recall, when two sets of procedures were introduced, one that led subjects to reconstruct the story and one that led subjects to reproduce the story.},

The goal of this study was to compare developmental trajectories of externalizing and internalizing problems in 6- to 12-year-old twins and singletons. Child Behavior Checklist (CBCL) maternal reports of externalizing and internalizing problems were obtained for a sample of 9651 twins from the Netherlands Twin Register and for a representative general population sample of 1351 singletons. Latent growth modeling was applied to estimate growth curves for twins and singletons. Twin-singleton differences in the intercepts and slopes of the growth curves were examined. The developmental trajectories of externalizing problems showed a linear decrease over time, and were not significantly different for twins and singletons. Internalizing problems seem to develop similarly for twins and singletons up to age 9. After this age twins' internalizing symptoms start to decrease in comparison to those of singletons, resulting in less internalizing problems than singletons by the age of 12 years. Our findings confirm the generalizability of twin studies to singleton populations with regard to externalizing problems in middle and late childhood. The generalizability of studies on internalizing problems in early adolescence in twin samples should be addressed with care. Twinship may be a protective factor in the development of internalizing problems during early adolescence.},

title = {On Stepwise Control of the Generalized Familywise Error Rate},
abstract = { A classical approach for dealing with the multiple testing problem is to restrict attention to procedures that control the familywise error rate (FWER), the probability of at least one false rejection. In many applications, one might be willing to tolerate more than one false rejection provided the number of such cases is controlled, thereby increasing the ability of the procedure to detect false null hypotheses. This suggests replacing control of the FWER by controlling the probability of {\$}k{\$} or more false rejections, which is called the {\$}k{\$}-FWER. In this article, a unified approach is presented for deriving the {\$}k{\$}-FWER controlling procedures. We first generalize the well-known closure principle in the context of the FWER to the case of controlling the {\$}k{\$}-FWER. Then, we discuss how to derive the {\$}k{\$}-FWER controlling stepwise (stepdown or stepup) procedures based on marginal {\$}p{\$}-values using this principle. We show that, under certain conditions, generalized closed testing procedures can be reduced to stepwise procedures, and any stepwise procedure is equivalent to a generalized closed testing procedure. Finally, we generalize the well-known Hommel procedure in two directions, and show that any generalized Hommel procedure is equivalent to a generalized closed testing procedure with the same critical values. },

title = {SCAN: SNP and copy number annotation},
abstract = {MOTIVATION: Genome-wide association studies (GWAS) generate relationships between hundreds of thousands of single nucleotide polymorphisms (SNPs) and complex phenotypes. The contribution of the traditionally overlooked copy number variations (CNVs) to complex traits is also being actively studied. To facilitate the interpretation of the data and the designing of follow-up experimental validations, we have developed a database that enables the sensible prioritization of these variants by combining several approaches, involving not only publicly available physical and functional annotations but also multilocus linkage disequilibrium (LD) annotations as well as annotations of expression quantitative trait loci (eQTLs). RESULTS: For each SNP, the SCAN database provides: (i) summary information from eQTL mapping of HapMap SNPs to gene expression (evaluated by the Affymetrix exon array) in the full set of HapMap CEU (Caucasians from UT, USA) and YRI (Yoruba people from Ibadan, Nigeria) samples; (ii) LD information, in the case of a HapMap SNP, including what genes have variation in strong LD (pairwise or multilocus LD) with the variant and how well the SNP is covered by different high-throughput platforms; (iii) summary information available from public databases (e.g. physical and functional annotations); and (iv) summary information from other GWAS. For each gene, SCAN provides annotations on: (i) eQTLs for the gene (both local and distant SNPs) and (ii) the coverage of all variants in the HapMap at that gene on each high-throughput platform. For each genomic region, SCAN provides annotations on: (i) physical and functional annotations of all SNPs, genes and known CNVs within the region and (ii) all genes regulated by the eQTLs within the region.

title = {Two-year-olds with autism orient to non-social contingencies rather than biological motion},
abstract = {Typically developing human infants preferentially attend to biological motion within the first days of life. This ability is highly conserved across species and is believed to be critical for filial attachment and for detection of predators. The neural underpinnings of biological motion perception are overlapping with brain regions involved in perception of basic social signals such as facial expression and gaze direction, and preferential attention to biological motion is seen as a precursor to the capacity for attributing intentions to others. However, in a serendipitous observation, we recently found that an infant with autism failed to recognize point-light displays of biological motion, but was instead highly sensitive to the presence of a non-social, physical contingency that occurred within the stimuli by chance. This observation raised the possibility that perception of biological motion may be altered in children with autism from a very early age, with cascading consequences for both social development and the lifelong impairments in social interaction that are a hallmark of autism spectrum disorders. Here we show that two-year-olds with autism fail to orient towards point-light displays of biological motion, and their viewing behaviour when watching these point-light displays can be explained instead as a response to non-social, physical contingencies--physical contingencies that are disregarded by control children. This observation has far-reaching implications for understanding the altered neurodevelopmental trajectory of brain specialization in autism.},

title = {A random forest approach to the detection of epistatic interactions in case-control studies},
abstract = {BACKGROUND: The key roles of epistatic interactions between multiple genetic variants in the pathogenesis of complex diseases notwithstanding, the detection of such interactions remains a great challenge in genome-wide association studies. Although some existing multi-locus approaches have shown their successes in small-scale case-control data, the "combination explosion" course prohibits their applications to genome-wide analysis. It is therefore indispensable to develop new methods that are able to reduce the search space for epistatic interactions from an astronomic number of all possible combinations of genetic variants to a manageable set of candidates. RESULTS: We studied case-control data from the viewpoint of binary classification. More precisely, we treated single nucleotide polymorphism (SNP) markers as categorical features and adopted the random forest to discriminate cases against controls. On the basis of the gini importance given by the random forest, we designed a sliding window sequential forward feature selection (SWSFS) algorithm to select a small set of candidate SNPs that could minimize the classification error and then statistically tested up to three-way interactions of the candidates. We compared this approach with three existing methods on three simulated disease models and showed that our approach is comparable to, sometimes more powerful than, the other methods. We applied our approach to a genome-wide case-control dataset for Age-related Macular Degeneration (AMD) and successfully identified two SNPs that were reported to be associated with this disease. CONCLUSION: Besides existing pure statistical approaches, we demonstrated the feasibility of incorporating machine learning methods into genome-wide case-control studies. The gini importance offers yet another measure for the associations between SNPs and complex diseases, thereby complementing existing statistical measures to facilitate the identification of epistatic interactions and the understanding of epistasis in the pathogenesis of complex diseases.},

title = {Online genetic databases informing human genome epidemiology},
abstract = {BACKGROUND: With the advent of high throughput genotyping technology and the information available via projects such as the human genome sequencing and the HapMap project, more and more data relevant to the study of genetics and disease risk will be produced. Systematic reviews and meta-analyses of human genome epidemiology studies rely on the ability to identify relevant studies and to obtain suitable data from these studies. A first port of call for most such reviews is a search of MEDLINE. We examined whether this could be usefully supplemented by identifying databases on the World Wide Web that contain genetic epidemiological information. METHODS: We conducted a systematic search for online databases containing genetic epidemiological information on gene prevalence or gene-disease association. In those containing information on genetic association studies, we examined what additional information could be obtained to supplement a MEDLINE literature search. RESULTS: We identified 111 databases containing prevalence data, 67 databases specific to a single gene and only 13 that contained information on gene-disease associations. Most of the latter 13 databases were linked to MEDLINE, although five contained information that may not be available from other sources. CONCLUSION: There is no single resource of structured data from genetic association studies covering multiple diseases, and in relation to the number of studies being conducted there is very little information specific to gene-disease association studies currently available on the World Wide Web. Until comprehensive data repositories are created and utilized regularly, new data will remain largely inaccessible to many systematic review authors and meta-analysts.},

title = {Testing for Measurement Invariance with Latent Class Analysis},
abstract = {Testing for measurement invariance can be done within the context of multigroup latent class analysis. Latent class analysis can model any type of discrete level data, which makes it an obvious choice when nominal indicators are used or when a researcher's aim is at classifying respondents in latent classes. The multigroup latent class (LC) model can be specified in three different ways, i.e. by adopting a probabilistic, a log-linear or a logistic parameterization. We define and compare these different forms of parameterization. The starting point is the standard LC model in which indicators and latent variables are defined at the nominal level. Additionally, we focus on LC models with ordinal indicators as well as LC factor models with ordinal indicators. Testing for measurement invariance involves estimating LC models
with different degrees of homogeneity. We explain the procedure for investigating measurement invariance at both the scale as well as the item level. We illustrate the approach with two examples. The first example is a multigroup LC analysis with nominal indicators; the second a multigroup LC factor analysis with ordinal indicators.},

title = {Summary measures and statistics for comparison of quality of life in a clinical trial of cancer therapy},
abstract = {Assessment of health related quality of life (QOL) has become an important endpoint in many clinical trials of cancer therapy. Most of these studies entail multiple QOL scales that are assessed repeatedly over time. As a result, the problem of multiple comparisons is a primary analytic challenge with these trials. The use of summary measures and statistics both reduces the number of hypotheses tested and facilitates the interpretation of trial results where the primary question is 'Does the overall QOL differ between treatment arms?' I present two classes of summary measures that are sensitive to consistent trends in the same direction across multiple assessment times or multiple QOL scales. Missing data strongly influences the choice between the two classes, where one class handles missing data on an individual basis, while the other class uses model-based strategies. I present the results from a clinical trial of adjuvant therapy for breast cancer that use summary measures with a focus on the practical issues that affect these analysis strategies, such as missing data and integration of QOL with efficacy endpoints such as survival.},

abstract = {AIM: To compare gene expression profiles of pancreatic adenocarcinoma tissue specimens, human pancreatic and colon adenocarcinoma and leukemia cell lines and normal pancreas samples in order to distinguish differentially expressed genes and to validate the differential expression of a subset of genes by quantitative real-time RT-PCR (RT-QPCR) in endoscopic ultrasound-guided fine needle aspiration (EUS-guided FNA) specimens. METHODS: Commercially dedicated cancer cDNA macroarrays (Atlas Human Cancer 1.2) containing 1176 genes were used. Different statistical approaches (hierarchical clustering, principal component analysis (PCA) and SAM) were used to analyze the expression data. RT-QPCR and immunohistochemical studies were used for validation of results. RESULTS: RT-QPCR validated the increased expression of LCN2 (lipocalin 2) and for the first time PLAT (tissue-type plasminogen activator or tPA) in malignant pancreas as compared with normal pancreas. Immunohistochemical analysis confirmed the increased expression of LCN2 protein localized in epithelial cells of ducts invaded by carcinoma. The analysis of PLAT and LCN2 transcripts in 12 samples obtained through EUS-guided FNA from patients with pancreatic adenocarcinoma showed significantly increased expression levels in comparison with those found in normal tissues, indicating that a sufficient amount of high quality RNA can be obtained with this technique. CONCLUSION: Expression profiling is a useful method to identify biomarkers and potential target genes. Molecular analysis of EUS-guided FNA samples in pancreatic cancer appears as a valuable strategy for the diagnosis of pancreatic adenocarcinomas.},

title = {The Substance Use Risk Profile Scale: a scale measuring traits linked to reinforcement-specific substance use profiles},
abstract = {The Substance Use Risk Profile Scale (SURPS) is based on a model of personality risk for substance abuse in which four personality dimensions (hopelessness, anxiety sensitivity, impulsivity, and sensation seeking) are hypothesized to differentially relate to specific patterns of substance use. The current series of studies is a preliminary exploration of the psychometric properties of the SURPS in two populations (undergraduate and high school students). In study 1, an analysis of the internal structure of two versions of the SURPS shows that the abbreviated version best reflects the 4-factor structure. Concurrent, discriminant, and incremental validity of the SURPS is supported by convergent/divergent relationships between the SURPS subscales and other theoretically relevant personality and drug use criterion measures. In Study 2, the factorial structure of the SURPS is confirmed and evidence is provided for its test-retest reliability and validity with respect to measuring personality vulnerability to reinforcement-specific substance use patterns. In Study 3, the SURPS was administered in a more youthful population to test its sensitivity in identifying younger problematic drinkers. The results from the current series of studies demonstrate support for the reliability and construct validity of the SURPS, and suggest that four personality dimensions may be linked to substance-related behavior through different reinforcement processes. This brief assessment tool may have important implications for clinicians and future research.},

title = {The construct and measurement equivalence of cocaine and opioid dependences: a National Drug Abuse Treatment Clinical Trials Network (CTN) study},
abstract = {INTRODUCTION: Although DSM-IV criteria are widely used in making diagnoses of substance use disorders, gaps exist regarding diagnosis classification, use of dependence criteria, and effects of measurement bias on diagnosis assessment. We examined the construct and measurement equivalence of diagnostic criteria for cocaine and opioid dependences, including whether each criterion maps onto the dependence construct, how well each criterion performs, how much information each contributes to a diagnosis, and whether symptom-endorsing is equivalent between demographic groups. METHODS: Item response theory (IRT) and multiple indicators-multiple causes (MIMIC) modeling were performed on a sample of stimulant-using methadone maintenance patients enrolled in a multisite study of the National Drug Abuse Treatment Clinical Trials Network (CTN) (N=383). Participants were recruited from six community-based methadone maintenance treatment programs associated with the CTN and major U.S. providers. Cocaine and opioid dependences were assessed by DSM-IV Checklist. RESULTS: IRT modeling showed that symptoms of cocaine and opioid dependences, respectively, were arrayed along a continuum of severity. All symptoms had moderate to high discrimination in distinguishing drug users between severity levels. "Withdrawal" identified the most severe symptom of the cocaine dependence continuum. MIMIC modeling revealed some support for measurement equivalence. CONCLUSIONS: Study results suggest that self-reported symptoms of cocaine and opioid dependences and their underlying constructs can be measured appropriately among treatment-seeking polysubstance users.},

abstract = {ABSTRACT: Greater Involvement of People Living with HIV/AIDS represents a mobilising and an organising principle for the involvement of people living with HIV in program and policy responses. People with HIV have been at the forefront of designing and implementing effective HIV treatment, care and prevention activities. However, governments and health systems have yet to act to fully harness the potential and resources of people living with HIV in addressing the epidemic.The lives and experiences of people living with HIV highlight the need for a shift in the existing paradigm of disease management. The high prevalence of HIV amongst health care providers in many countries, exacerbated by stigma towards those with HIV in the health care professions, is seriously undermining the capacity of health systems and signals the need to change the current nature of health care delivery. Moreover, the negative experiences of many people with HIV in relation to their health care as well as in their daily social interactions, coupled with the ever-limited current investment in treatment, care and support, demonstrate that the current system is drastically failing the majority of people with HIV. Current health management systems urgently need to be more effectively maximised, to increase the quality of standards of health care systems and services in resource poor countries. An integrated approach to health care based on a human rights framework, grounded in community realities and delivered in partnership and solidarity with people living with HIV, offers the most viable approach to overcoming the crisis of HIV in the health care system.},

title = {Selecting pre-screening items for early intervention trials of dementia--a case study},
abstract = {Our goal was to review and extend statistical methods for discriminating between normal subjects and those with dementia or cognitive impairment. We compared six different methods to one constructed by expert opinion, in their brevity and predictive power. The methods include logistic regression and neural networks, with standard and least absolute shrinkage and selection operator (LASSO) variable selection, as well as decision trees with and without boosting. These methods were applied to the baseline data of a subgroup of subjects in a dementia study, using their screening interview items to predict their clinical diagnosis of normal or non-normal (cognitively impaired or demented). The derived models were then validated on a different subgroup of subjects in the same study who had the screening and clinical diagnosis two to five years later. Performance of different models was compared based on their sensitivity and specificity in the validation sample. Generally, the six statistical methods performed slightly to moderately better than the expert-opinion model. Neural networks generally performed better than the logistic and decision tree models. LASSO improved the performance of logistic and neural network models, but it eliminated few input variables in the neural network. The single decision tree performed at least as well as the standard logistic model, and with fewer items, making it an attractive pre-screening tool. Using the boosting option for decision trees did not substantially improve the performance. We recommend that for each situation, different methods of classification should be attempted to obtain optimal results for a given purpose.},

abstract = {A universal problem in genetic association studies is to distinguish associations due to genuine effects of the locus under investigation, or linkage disequilibrium with a nearby locus that has a genuine effect, from associations due to population stratification or other artifacts. Fulker et al. (1999) have suggested a test using unselected sib pairs to distinguish these two causes of association. The test is readily implemented within a standard maximum-likelihood framework using the MXpackage. The approach is applied to data on ADH2 genotypes and a measure of alcohol consumption from an Australian DZ twin pair sample. Results indicate that the association of the ADH2*2 allele with lower alcohol consumption cannot be explained by simple admixture and that there may be genuine allelic effects of the locus on alcohol consumption. Power calculations are provided to show that these results are plausible for the sample size in this study and con- sider the effects of genetic architecture and sample structure on required sample sizes for the Fulker et al. test.},

We report on a classification tree, based on the results of nonparametric multiple comparisons, which results in the bipolar hierarchical clustering of genes in relation to their response to treatment. In addition to identifying treatment-responsive genes, application of this procedure to our test study identified the known pharmacological relationships among the treatment groups without supervision. Also, small treatment-specific subsets of genes were identified that may be indicative of additional pharmacophores present in the test compounds.},

Our prior for item pa- rameters is a mixture distribution to accommodate situations where different groups of countries have different measurement operations, while countries within these groups are still allowed to be heteroge- neous. A simulation study is conducted that shows that all parameters can be recovered. We also apply the model to real data on the two components of affective subjective well-being: positive affect and negative affect. The psychometric behavior of these two scales is studied in 28 countries across four continents.},

abstract = {A latent profile analysis was conducted on the co-occurring symptoms of 423 adolescents diagnosed with major depressive disorder as part of the Treatment for Adolescents with Depression Study (TADS), a multisite, randomized treatment trial. The participants had a mean (SD) age of 14.6 (1.5) years; of the sample, 45.6% was male and 73.8% was white. Scores on the primary subscales of Conners' Parent Rating Scale--Revised were used as indicators in the analysis. Five classes of symptoms best described the clinical presentation of adolescents enrolled in the TADS. Of the adolescents in the sample, 80% were assigned to classes with clinically significant elevations on 1 or more subscales of the Children's Depression Rating Scale--Revised. The 5 classes met empirical criteria for distinctiveness and were validated against clinical diagnoses, child-rated symptoms, and clinician-rated functional impairment. The findings are consistent with prior studies that showed a high rate of co-occurring symptoms among depressed adolescents. The discussion focuses on understanding subtypes and comorbidity in adolescent depression as well as the implications for treatment and for prevention.},

title = {A mixture of experts latent position cluster model for social network data},
abstract = {Social network data represent the interactions between a group of social actors. Interactions between colleagues and friendship networks are typical examples of such data.
The latent space model for social network data locates each actor in a network in a latent (social) space and models the probability of an interaction between two actors as a function of their locations. The latent position cluster model extends the latent space model to deal with network data in which clusters of actors exist --- actor locations are drawn from a finite mixture model, each component of which represents a cluster of actors.
A mixture of experts model builds on the structure of a mixture model by taking account of both observations and associated covariates when modeling a heterogeneous population. Herein, a mixture of experts extension of the latent position cluster model is developed. The mixture of experts framework allows covariates to enter the latent position cluster model in a number of ways, yielding different model interpretations.
Estimates of the model parameters are derived in a Bayesian framework using a Markov Chain Monte Carlo algorithm. The algorithm is generally computationally expensive --- surrogate proposal distributions which shadow the target distributions are derived, reducing the computational burden.
The methodology is demonstrated through an illustrative example detailing relationships between a group of lawyers in the USA.},

title = {Effects of phone versus mail survey methods on the measurement of health-related quality of life and emotional and behavioural problems in adolescents},
abstract = {BACKGROUND: Telephone interviews have become established as an alternative to traditional mail surveys for collecting epidemiological data in public health research. However, the use of telephone and mail surveys raises the question of to what extent the results of different data collection methods deviate from one another. We therefore set out to study possible differences in using telephone and mail survey methods to measure health-related quality of life and emotional and behavioural problems in children and adolescents. METHODS: A total of 1700 German children aged 8-18 years and their parents were interviewed randomly either by telephone or by mail. Health-related Quality of Life (HRQoL) and mental health problems (MHP) were assessed using the KINDL-R Quality of Life instrument and the Strengths and Difficulties Questionnaire (SDQ) children's self-report and parent proxy report versions. Mean Differences ("d" effect size) and differences in Cronbach alpha were examined across modes of administration. Pearson correlation between children's and parents' scores was calculated within a multi-trait-multi-method (MTMM) analysis and compared across survey modes using Fisher-Z transformation. RESULTS: Telephone and mail survey methods resulted in similar completion rates and similar socio-demographic and socio-economic makeups of the samples. Telephone methods resulted in more positive self- and parent proxy reports of children's HRQoL (SMD < or = 0.27) and MHP (SMD < or = 0.32) on many scales. For the phone administered KINDL, lower Cronbach alpha values (self/proxy Total: 0.79/0.84) were observed (mail survey self/proxy Total: 0.84/0.87). KINDL MTMM results were weaker for the phone surveys: mono-trait-multi-method mean r = 0.31 (mail: r = 0.45); multi-trait-mono-method mean (self/parents) r = 0.29/0.36 (mail: r = 0.34/0.40); multi-trait-multi-method mean r = 0.14 (mail: r = 0.21). Weaker MTMM results were also observed for the phone administered SDQ: mono-trait-multi-method mean r = 0.32 (mail: r = 0.40); multi-trait-mono-method mean (self/parents) r = 0.24/0.30 (mail: r = 0.20/0.32); multi-trait-multi-method mean r = 0.14 (mail = 0.14). The SDQ classification into borderline and abnormal for some scales was affected by the method (OR = 0.36-1.55). CONCLUSIONS: The observed differences between phone and mail surveys are small but should be regarded as relevant in certain settings. Therefore, while both methods are valid, some changes are necessary. The weaker reliability and MTMM validity associated with phone methods necessitates improved phone adaptations of paper and pencil questionnaires. The effects of phone versus mail survey modes are partly different across constructs/measures.},

title = {Testing whether genetic variation explains correlation of quantitative measures of gene expression, and application to genetic network analysis},
abstract = {Genetic networks for gene expression data are often built by graphical models, which in turn are built from pair-wise correlations of gene expression levels. A key feature of building graphical models is the evaluation of conditional independence of two traits, given other traits. When conditional independence can be assumed, the traits that are conditioned on are considered to 'explain' the correlation of a pair of traits, allowing efficient building and interpretation of a network. Overlaying genetic polymorphisms, such as single nucleotide polymorphisms (SNPs), on quantitative measures of gene expression provides a much richer set of data to build a genetic network, because it is possible to evaluate whether sets of SNPs 'explain' the correlation of gene expression levels. However, there is strong evidence that gene expression levels are controlled by multiple interacting genes, suggesting that it will be difficult to reduce the partial correlation completely to zero. Ignoring the fact that some sets of SNPs can explain at least part of the correlation between gene expression levels, if not all, might result in missing important clues on the genetic control of gene expression. To enrich the assessment of the causes of correlation between gene expression levels, we develop methods to evaluate whether a set of covariates (e.g. SNPs, or even a set of quantitative expression transcripts) explains at least some of the correlation of gene expression levels. These methods can be used to assist the interpretation of regulation of gene expression and the construction of gene regulatory networks.},

To evaluate the adequacy of this instrument as an outcome measure for a large-scale, multicenter, randomized clinical trial, we used Rasch analysis to address three questions: (1) Are the scales interval-level? (2) Do the scales measure precisely across the entire range of dyspepsia outcomes? (3) Do the scales' items have an optimal number of response categories? We found that the scales were not interval-level and that they did not measure effectively at low or high levels of the dyspepsia-related outcomes. Our results also suggest that patients were capable of discriminating among only four- to seven-item response categories. Further studies are needed to identify items that effectively measure high and low levels of dyspepsia-related outcomes and to validate that decreasing the number of response categories improves the psychometric properties of these scales.},

title = {Variational Bayesian Learning of Directed Graphical Models with Hidden Variables},
abstract = {A key problem in statistics and machine learning is inferring suitable structure of a model given some observed data. A Bayesian approach to model comparison makes use of the marginal likelihood of each candidate model to form a posterior distribution over models; unfortunately for most models of interest, notably those containing hidden or latent variables, the marginal likelihood is intractable to compute.
We present the variational Bayesian (VB) algorithm for directed graphical mod- els, which optimises a lower bound approximation to the marginal likelihood in a procedure similar to the standard EM algorithm. We show that for a large class of models, which we call conjugate exponential, the VB algorithm is a straightfor- ward generalisation of the EM algorithm that incorporates uncertainty over model parameters. In a thorough case study using a small class of bipartite DAGs con- taining hidden variables, we compare the accuracy of the VB approximation to existing asymptotic-data approximations such as the Bayesian Information Crite- rion (BIC) and the Cheeseman-Stutz (CS) criterion, and also to a sampling based gold standard, Annealed Importance Sampling (AIS). We find that the VB algo- rithm is empirically superior to CS and BIC, and much faster than AIS. Moreover, we prove that a VB approximation can always be constructed in such a way that guarantees it to be more accurate than the CS approximation.},

abstract = {Objective: Propensity scores for the analysis of observational data are typically estimated using logistic regression. Our objective in this review was to assess machine learning alternatives to logistic regression, which may accomplish the same goals but with fewer assump- tions or greater accuracy.
Study Design and Setting: We identified alternative methods for propensity score estimation and/or classification from the public health, biostatistics, discrete mathematics, and computer science literature, and evaluated these algorithms for applicability to the problem of propensity score estimation, potential advantages over logistic regression, and ease of use.
Results: We identified four techniques as alternatives to logistic regression: neural networks, support vector machines, decision trees (classification and regression trees [CART]), and meta-classifiers (in particular, boosting).
Conclusion: Although the assumptions of logistic regression are well understood, those assumptions are frequently ignored. All four alternatives have advantages and disadvantages compared with logistic regression. Boosting (meta-classifiers) and, to a lesser extent, decision trees (particularly CART), appear to be most promising for use in the context of propensity score analysis, but extensive simulation studies are needed to establish their utility in practice.},

abstract = {The availability of different designs and tests to detect QTLs in association studies raises questions about the relative merits of the various approaches. We therefore compared the power of quantitative versus categorical tests, the power in population samples versus sam- ples with subjects selected on the basis of their trait scores, and the power of tests that con- trol for population stratification using parental genotypes versus tests that do not control for stratification. In case-control samples the power of quantitative tests was clearly better than that of categorical tests especially when the control group was a population sample. In sam- ples of genotyped trios of cases and their parents, the power of quantitative tests was much poorer. Compared to population samples, selection always improved the power in case-control samples where the controls were sampled from the opposite end of the continuum and fre- quently deteriorated the power when the controls were a population sample. Mainly because subjects with at least one heterozygous parent need to be selected, the use of tests that con- trol for stratification resulted in a substantial decrease of power. In the final section our power calculations were integrated into a more general discussion about optimizing designs in association studies.},

Gratitude had small correlations with autonomy (r = .17), and medium to large correlations with environmental mastery, per- sonal growth, positive relationships, purpose in life, and self-acceptance (rs ranged from .28 to .61). After controlling for the 30 facets of the Big Five, gratitude explained a substantial amount of a unique variance in most aspects of psychological well-being (requivalent = .14 to .25). Gratitude is concluded to be uniquely important to psychological well-being, beyond the effect of the Big Five facets.},

title = {Testing a hierarchical model of anxiety and depression in adolescents: A tri-level model},
abstract = {The present study examined the structural relationships among anxiety and depressive symptoms in a sample of high school juniors. The best-fitting structural representation was a tri-level hierarchical arrangement with a broad general factor (general distress), two factors of intermediate breadth (anxious-misery and fears), and five conceptually meaningful, narrow group factors. In accord with the integrative hierarchical model of anxiety and depression, the results supported a structure with a symptom factor central to major depression, and other symptom factors specific to particular anxiety disorders. These group factors displayed significant, unique associations with clinician severity ratings (CSRs) for their respective DSM diagnoses. The hierarchical arrangement demonstrated temporal invariance over a one-year period and configural and partial metric invariance in females and males. Implications for DSM classification and arrangement of anxiety and depressive disorders are discussed as is how present findings help bridge existing research conducted at symptom and diagnostic levels.},

title = {Motor function in Parkinson's disease and supranuclear palsy: simultaneous factor analysis of a clinical scale in several populations},
abstract = {BACKGROUND: In order to better understand the similarities and differences in the motor behaviour of different groups of patients, their scores on the Motor Examination section of the Unified Parkinson's Disease Rating Scale (UPDRS) were analysed simultaneously. The three groups consisted, respectively, of patients with Parkinson's disease (PD) on medication, patients with Parkinson's disease withdrawn from anti-parkinsonian medication for at least 12 hours, and patients diagnosed with a specific Parkinsonism syndrome: Progressive Supranuclear Palsy (PSP). METHODS: A total of 669 consecutively sampled patients from three separate hospital-based clinics participated (294 PD on medication; 200 PD off medication: 175 PSP). The Motor Examination section of the UPDRS was administered by neurologists at the three participating clinics. The patient scores on each item were recorded. To assess similarities and differences among the components of the UPDRS in these samples, we performed simultaneous or multigroup factor analysis on the covariance matrices of the three groups. In addition, it was investigated whether a single model for the Motor Examination section of the UPDRS could be developed which would be valid for all three groups at the same time. RESULTS: A single six-dimensional factor solution was found that fitted all groups, although this was not straightforward due to differences between the tremor-at-rest variables. The factors were identified as Tremor-at-rest, Postural Tremor, Axial Dysfunctioning, Rigidity, Left Bradykinesia and Right Bradykinesia. The analysis also pointed to a somewhat lower lateralization in bradykinesia for PSP patients. The groups differed in intensity of motor impairment, especially with respect to Tremor-at-Rest, but the overall relationships between the variables were shared by the three groups. In addition, apart from the common factor structure evidence of differences in body part-specific and motor-specific variances was found. CONCLUSION: From a clinical point of view, the analyses showed that using the Motor Examination section of the UPDRS is also appropriate for patients with PSP, because the correlational structure of the items is directly comparable to that of Parkinson's patients. Methodologically, the analysis of all groups together showed that it is possible to evaluate similarities and differences between factor structures in great detail.},

title = {Gender differences in the etiology of anxiety sensitivity: a twin study},
abstract = {OBJECTIVE: To estimate the magnitude of genetic and environmental factors on anxiety sensitivity by gender. DESIGN: Classic twins reared-together study design. PATIENTS: A community sample of 337 twin pairs, including 179 monozygotic (45 brother and 134 sister pairs) and 158 dizygotic (28 brother, 94 sister, and 36 brother-sister pairs). METHOD: Twin pairs completed the Anxiety Sensitivity Index (ASI) using a postal survey design. The ASI is composed of three factors: (1) fear of anxiety-related somatic sensations; (2) fear of cognitive dyscontrol due to beliefs that sensations like depersonalization are signs of mental illness (e.g., fear of concentration problems); and (3) fear of publicly observable anxiety reactions (e.g., fear of trembling). Biometrical modeling techniques were used to estimate heritability of the ASI dimensions by gender. RESULTS: ASI factors are heritable only in women, accounting for 37% to 48% of the total variance (median, 44.5%). Environmental factors accounted for all the variability in men. CONCLUSIONS: These findings have implications for understanding the etiology of panic disorder. Previous research suggests that anxiety sensitivity is a risk factor or diathesis for this disorder, and that panic disorder is more prevalent in women than men. Our findings suggest the hypothesis that the increased prevalence in women may occur because anxiety sensitivity is heritable in women.},

Results suggest that DESC may be appropriately used to screen for depression and may be beneficial for repeated measurements.},

title = {Influence of behaviour and risk factors on motor performance in preterm infants at age 2 to 3 years},
abstract = {The aim of this cross-sectional study was to determine the influence of test-taking behaviour and risk factors for delayed motor performance in 437 preterm infants (244 males, 193 females; < or = 32 weeks of gestation) at the corrected age of 2 to 3 years (mean 29mo [SD 3.3]). Other mean (SD) sample demographics were: postmenstrual age 29(+5) weeks (1(+5)), range 25(+0)-32(+0); birthweight 1213.7g (331.7), range 468-2350; and days in the neonatal intensive care unit 21.1 (21.3), range 1-165. Children (n=23) with a severe disability were excluded. We assessed motor performance and behaviour during testing with the Motor Scale and the Behaviour Rating Scale (BRS) of the Bayley Scales of Infant Development, 2nd edition (BSID-II). Risk factors were tested against delayed motor performance as the dependent variable in binary logistic regression analysis. Median score on the Motor Scale in terms of the BSID-II Psychomotor Developmental Index (PDI) was 86. 'Delayed' motor performance was observed in 46.5% of the children tested, and behaviour was 'not-optimal' in 31.4%. The Motor Scale and BRS scores were significantly correlated (r(s)=0.62, p<0.01). Risk factors for delayed motor performance were: neonatal convulsions (odds ratio [OR] 4.5; 95% confidence interval [CI] 1.6-12.9), low maternal educational level (OR 3.3; 95% CI 1.7-6.5), male sex (OR 2.8; 95% CI 1.8-4.3), and chronic lung disease (OR 2.1; 95% CI 1.1- 4.1). We conclude that preterm infants are at high risk of delayed motor performance and non-optimal test-taking behaviour.},

abstract = {In the new era of large-scale collaborative Genome Wide Association Studies (GWAS), population stratification has become a critical issue that must be addressed. In order to build upon the methods developed to control the confounding effect of a structured population, it is extremely important to visualize and quantify that effect. In this work, we develop methodology for single nucleotide polymorphism (SNP) selection and subsequent population stratification visualization based on deviation from Hardy-Weinberg equilibrium in conjunction with non-metric multidimensional scaling (MDS); a distance-based multivariate technique. Through simulation, it is shown that SNP selection based on Hardy-Weinberg disequilibrium (HWD) is robust against confounding linkage disequilibrium patterns that have been problematic in past studies and methods as well as producing a differentiated SNP set. Non-metric MDS is shown to be a multivariate visualization tool preferable to principal components in conjunction with HWD SNP selection through theoretical and empirical study from HapMap samples. The proposed selection tool offers a simple and effective way to select appropriate substructure-informative markers for use in exploring the effect that population stratification may have in association studies.},

An electronic bibliographic search was used to investigate the psychometric properties of the HRQoL studies. The data bases explored were the following: Medline, HealthStar, and IME. A specifically developed index was used the GRAQoL index, aiming at the evaluation of 11 psychometric and non-psychometric properties of the study designs. The values of the GRAQoL index range from 0 to 100. The authors conclude that the level of research in HRQoL index range from 0 to 100. The authors conclude that the level of research in HRQoL in Spain is high with a number of research teams being actively involved in many ar- eas of generic and specific quality of life instruments. Further research in HRQoL would provide interesting results for ment assessment of clinical ef- fectiveness.},

abstract = {Altered hippocampal volume, the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism, and neuroticism have each been implicated in the etiology of psychiatric disorders, especially depression. However, the relationship between these variables is not well understood. Here, we determined the effects of the BDNF Val66met polymorphism on the five-factor personality dimensions (assessed using the NEO-FFI), trait depression (assessed with the DASS-21) in a cross-sectional cohort of 467 healthy volunteers. A large matched subset of this cohort was also assessed for grey matter volume of the hippocampus and contiguous temporal cortical regions using magnetic resonance imaging. In Met carriers, elevations in neuroticism and trait depression and stress were associated with lower mean hippocampal volume, but there were no such associations in Val homozygotes. Trait depression, in particular, was found to moderate the effects of BDNF genotypes on hippocampal volume. Met carriers with high trait depression showed a reduction in grey matter volume of the mean hippocampus compared with Val homozygotes. These findings suggest that even in otherwise healthy subjects, trait depression may contribute to the susceptibility of Met carriers to hippocampal grey matter loss.},

title = {The HP5 inventory: definition and assessment of five health-relevant personality traits from a five-factor model perspective},
abstract = {The aim of the present project was to construct a short personality inventory specifically applicable in per- sonality and health research. The development began with a demarcation of some specific constructs thought to be relevant in explaining individual differences influencing the vulnerability to illness and illness progression as well as psychosocial adaptation to illness. Factor analytic procedures were used separately in two different samples to derive the scales from an item pool. Two confirmation samples were used in addition for cross- validating the final model. In addition, scales from other personality inventories were used to further vali- date the new scales. A total of 20 items were chosen to constitute the new instrument, entitled the HP5i (H for Health-relevant; P for personality; 5 for its correspondence with the FFM taxonomy; and i for inventory). The five scales were labeled Antagonism (as a facet of Agreeableness), Impulsivity (as a facet of Con- scientiousness), Hedonic Capacity (as a facet of Extraversion), Negative Affectivity (as a facet of Neuroti- cism), and Alexithymia (as a facet of Openness). The new HP5 inventory Scales manifested a meaningful pattern of correlations with NEO PI-R Scales and with two alexithymia scales, thus suggesting some pre- liminary empirical evidence for convergent validity.},

title = {On the misuse of manifest variables in the detection of measurement bias},
abstract = {Measurement invariance (lack of bias) of a manifest variable Y with respect to a latent variable W is defined as invariance of the conditional distribution of Y given W over selected subpopulations. Invariance is commonly assessed by studying subpopulation differences in the conditional distribution of Ygiven a manifest variable Z, chosen to substitute for W. A unified treatment of conditions that may allow the detection of measurement bias using statistical procedures involving only observed or manifest variables is presented. Theorems are provided that give conditions for measurement invariance, and for invariance of the conditional distri- bution of Y given Z. Additional theorems and examples explore the Bayes sufficiency of Z, stochastic ordering in W, local independence of Y and Z, exponential families, and the reli- ability of Z. It is shown that when Bayes sufficiency of Z fails, the two forms of invariance will often not be equivalent in practice. Bayes sufficiency holds under Rasch model assumptions, and in long tests under certain conditions. It is concluded that bias detection procedures that rely strictly on observed variables are not in general diagnostic of measurement bias, or the lack of bias.},

title = {Depression and HIV risk behaviors among patients in a sexually transmitted disease clinic},
abstract = {OBJECTIVE: The authors' goal was to investigate the relationship between depression and HIV risk behaviors or sexually transmitted disease (STD) diagnosis at an urban STD clinic. METHOD: Using audio computer-assisted self-interview, 671 STD clinic patients answered questions about HIV risk behaviors and depression in a large-scale, cross-sectional study. A subset of the patients (N=201) was evaluated for current major depressive disorder by interviewers using the nonpatient edition of the Structured Clinical Interview for DSM-IV. RESULTS: Depressed patients were more likely to have sex for money or drugs, to have had sex with an intravenous drug user, to
