title = {Progress in NIRT Analysis of Polytomous Item Scores: Dilemmas and Practical Solutions},
abstract = {This paper discusses three open problems in nonparametric polytomous item re- sponse theory: (1) theoretically, the latent trait {\$}\theta{\$} is not stochastically ordered by the observed total score X+; (2) the models do not imply an invariant item ordering; and (3) the regression of an item score on the total score X+ or on the restscore R is not a monotone nondecreasing function and, as a result, it cannot be used for investigating the monotonicity of the item step response function. Tentative solutions for these problems are discussed. The computer program MSP for nonparametric IRT analysis is based on models which neither imply the stochastic ordering property nor an invariant item ordering. Also, MSP uses item-restscore regression for investigating item step response functions. It is discussed whether computer programs may be based temporarily) on models which lack desirable properties and use methods which are not (yet) supported by sound psychometric theory.},

Previous research demonstrated that HLA-DRB1 alleles encoding the shared epitope are specific for disease that is characterized by antibodies to cyclic citrullinated peptides (anti-CCP). In the present study, we incorporated the shared epitope and either anti-CCP antibodies or rheumatoid factor into linkage disequilibrium mapping, to assess the association between the shared epitope or antibodies with the disease gene identified. Incorporating the covariates into the association mapping provides a mechanism 1) to evaluate gene-gene and gene-environment interactions and 2) to dissect the pathways underlying disease induction/progress in quantitative antibodies.},

title = {Phenomics: the systematic study of phenotypes on a genome-wide scale},
abstract = {Phenomics is an emerging transdiscipline dedicated to the systematic study of phenotypes on a genome-wide scale. New methods for high-throughput genotyping have changed the priority for biomedical research to phenotyping, but the human phenome is vast and its dimensionality remains unknown. Phenomics research strategies capable of linking genetic variation to public health concerns need to prioritize development of mechanistic frameworks that relate neural systems functioning to human behavior. New approaches to phenotype definition will benefit from crossing neuropsychiatric syndromal boundaries, and defining phenotypic features across multiple levels of expression from proteome to syndrome. The demand for high throughput phenotyping may stimulate a migration from conventional laboratory to web-based assessment of behavior, and this offers the promise of dynamic phenotyping-the iterative refinement of phenotype assays based on prior genotype-phenotype associations. Phenotypes that can be studied across species may provide greatest traction, particularly given rapid development in transgenic modeling. Phenomics research demands vertically integrated research teams, novel analytic strategies and informatics infrastructure to help manage complexity. The Consortium for Neuropsychiatric Phenomics at UCLA has been supported by the National Institutes of Health Roadmap Initiative to illustrate these principles, and is developing applications that may help investigators assemble, visualize, and ultimately test multi-level phenomics hypotheses. As the transdiscipline of phenomics matures, and work is extended to large-scale international collaborations, there is promise that systematic new knowledge bases will help fulfill the promise of personalized medicine and the rational diagnosis and treatment of neuropsychiatric syndromes.},

abstract = {Impulsive unsocialized sensation seeking (ImpUSS) is a major factor discovered in factor analyses of scales used in psychobiological research. It is strongly convergent with Eysenck's P dimension and conscientiousness in the 'big five'. The components of the dimension and the P scale, have been validated as correlates of various kinds of disinhibited behaviors, criminality, sexuality, and substance use and abuse. ImpUSS is related to a failure in passive avoidance learning, probably as a function of impulsivity and attention to reward stimuli. Psychophysiological markers for the trait include strong orienting and weak defensive reflexes and an augmenting, rather than reducing, of cortical reaction to intense stimuli. At the neurochemical level the trait is related to low levels of monoamine oxidase (MAO) and the neurotransmitters norepinephrine and serotonin, and theoretically high levels of dopaminergic activity. The trait components have high heritabilities for a personality trait.},

abstract = {Depression and impaired quality of life (QOL) are frequently observed in patients suffering from a variety of diseases. In addition, it has been reported that an enhanced degradation of the serotonin precursor tryptophan may contribute to QOL deterioration in some diseases. However, it is unclear whether the correlation between the QOL scores and the central serotonergic tone is only mediated by the severity of either the depression symptoms or the physical illness itself. The present study examined the relationship between serotonin transporter (SERT) availability and life quality as measured by the World Health Organization Quality of Life brief version questionnaire (WHO-QOL) in healthy participants in order to exclude the influence of depressive mood and disease. The SERT availability in the midbrain was approximated using SPECT with [(123)I] ADAM ligand in fifty-eight healthy volunteers. The overall rating sub scores of the WHO-QOL correlated positively with serotonin transporter availability in the males. Central serotoninergic activity may play a role in the overall rating scores of the WHO-QOL.},

title = {Analytic methods for factors, dimensions and endpoints in clinical trials for Alzheimer's disease},
abstract = {Alzheimer's disease (AD) is a complex disease process, so finding a single biomarker to track in clinical trials has proven difficult. This paper describes and contrasts statistical methods that might be used with biomarkers in clinical trials for AD, highlighting their differences, limitations and interpretations. The first method is traditional regression, within which one dependent variable, the Best Empirically Supported Indicator (BESI), must be identified. In this approach one biomarker (e.g., the ratio of tau to Abeta42 from CSF) is the indicator for an individual's disease status, and change in that status. The second approach is an exploratory factor analysis (EFA) to consolidate a multitude of candidate dependent variables into a sample-dependent, mathematically-optimized smaller set of 'factors'. The third method is latent variable (LV) modeling of multiple indicators of an entity (e.g., "disease burden"). The LV approach can yield a complex 'dependent variable', the Best Measurement Model Indicator (BMMI). A measurement model represents an entity that several dependent variables reflect or measure, and so can include many 'dependent variables', and estimate their relative contributions to the underlying entity. The selection of a single BESI is an artifact of regression that limits the investigator's ability to utilize all relevant variables representing the entity of interest. EFA results in sample-specific combination of biomarkers that might not generalize to a new sample - and fit of the EFA results cannot be tested. Latent variable methods can be useful to construct powerful, efficient statistical models that optimally combine diverse biomarkers into a single, multidimensional dependent variable that can generalize across samples when they are theory-driven and not sample-dependent. This paper shows that EFA can work to uncover underlying structure, but that it does not always yield solutions that 'fit' the data. It is not recommended as a method to build BMMIs, which will be useful in establishing diagnostic criteria, creating and evaluating benchmarks, and monitoring progression in clinical trials.},

title = {Recalled parental bonding, adult attachment style, and personality disorders in child molesters: A comparative study},
abstract = {This article studies recalled parental bonding, adult attachment style, and personality disorders in child molesters and reports on the findings of two separate studies. The first study examines differences between a group of 84 child molesters and 80 matched normal control subjects. This study found that the antisocial and the schizoid personality disorders are typical for the molester group, and that at an interpersonal level this group can be typified by recollections of an uncaring father and mother, recollections of an elevated level of autonomy emanating from the father, and insecure current attachment patterns. The second study compares a subgroup of personality-disordered child molesters to a subgroup without personality disorders. This study revealed that recollections of the role of the father in parenting are decisive. The personality-disordered group reports that the father was both more uncaring and granted more autonomy. Regarding current adult attachment style, an avoidant and anxious-ambivalent attachment style characterised the disordered subgroup. We argue that the results can be useful for treatment. Since recalled parental experiences play a role in the development of personality disorders and child molestation, psychotherapists should integrate interpersonal tools into treatment, especially in therapeutic work with child molesters who received less parental sensitivity and suffer from personality disorders.},

abstract = {Adolescence is the transition period that prepares individuals for fulfilling their role as adults. Most conspicuous in this transition period is the peak level of risk-taking behaviors that characterize adolescent motivated behavior. Significant neural remodeling contributes to this change. This review focuses on the functional neuroanatomy underlying motivated behavior, and how ontogenic changes can explain the typical behavioral patterns in adolescence. To help model these changes and provide testable hypotheses, a neural systems-based theory is presented. In short, the Triadic Model proposes that motivated behavior is governed by a carefully orchestrated articulation among three systems, approach, avoidance and regulatory. These three systems map to distinct, but overlapping, neural circuits, whose representatives are the striatum, the amygdala and the medial prefrontal cortex. Each of these system-representatives will be described from a functional anatomy perspective that includes a review of their connectivity and what is known of their ontogenic changes.},

abstract = {BACKGROUND: Genome-wide association studies (GWASs) and global profiling of gene expression (microarrays) are two major technological breakthroughs that allow hypothesis-free identification of candidate genes associated with tumorigenesis. It is not obvious whether there is a consistency between the candidate genes identified by GWAS (GWAS genes) and those identified by profiling gene expression (microarray genes). METHODOLOGY/PRINCIPAL FINDINGS: We used the Cancer Genetic Markers Susceptibility database to retrieve single nucleotide polymorphisms from candidate genes for prostate cancer. In addition, we conducted a large meta-analysis of gene expression data in normal prostate and prostate tumor tissue. We identified 13,905 genes that were interrogated by both GWASs and microarrays. On the basis of P values from GWASs, we selected 1,649 most significantly associated genes for functional annotation by the Database for Annotation, Visualization and Integrated Discovery. We also conducted functional annotation analysis using same number of the top genes identified in the meta-analysis of the gene expression data. We found that genes involved in cell adhesion were overrepresented among both the GWAS and microarray genes. CONCLUSIONS/SIGNIFICANCE: We conclude that the results of these analyses suggest that combining GWAS and microarray data would be a more effective approach than analyzing individual datasets and can help to refine the identification of candidate genes and functions associated with tumor development.},

We present EM algo- rithms for different variants of the aspect model and derive an approximate EM algorithm based on a variational principle for the two-sided clus- tering model.

title = {Regularized binormal ROC method in disease classification using microarray data},
abstract = {BACKGROUND: An important application of microarrays is to discover genomic biomarkers, among tens of thousands of genes assayed, for disease diagnosis and prognosis. Thus it is of interest to develop efficient statistical methods that can simultaneously identify important biomarkers from such high-throughput genomic data and construct appropriate classification rules. It is also of interest to develop methods for evaluation of classification performance and ranking of identified biomarkers. RESULTS: The ROC (receiver operating characteristic) technique has been widely used in disease classification with low dimensional biomarkers. Compared with the empirical ROC approach, the binormal ROC is computationally more affordable and robust in small sample size cases. We propose using the binormal AUC (area under the ROC curve) as the objective function for two-sample classification, and the scaled threshold gradient directed regularization method for regularized estimation and biomarker selection. Tuning parameter selection is based on V-fold cross validation. We develop Monte Carlo based methods for evaluating the stability of individual biomarkers and overall prediction performance. Extensive simulation studies show that the proposed approach can generate parsimonious models with excellent classification and prediction performance, under most simulated scenarios including model mis-specification. Application of the method to two cancer studies shows that the identified genes are reasonably stable with satisfactory prediction performance and biologically sound implications. The overall classification performance is satisfactory, with small classification errors and large AUCs. CONCLUSION: In comparison to existing methods, the proposed approach is computationally more affordable without losing the optimality possessed by the standard ROC method.},

This paper provides an integrated review and interpretation of how PROs have been defined, measured, and used in a range of recent cancer research and policy initiatives. We focus, in turn, on the role of PRO measurement in the evaluation and approval of cancer therapies, the assessment of cancer care in the community, patient-provider decision making in clinical oncology practice, and population surveillance of cancer patients and survivors. The paper concludes with a discussion of future challenges and opportunities in PRO measure development and application, given the advancing state of the science in cancer outcomes measurement and the evolving needs of cancer decision makers at all levels.},

abstract = {Alcohol dependence (AD), a genetically influenced phenotype, is extremely costly to individuals and to society in the United States and throughout the world, contributing to morbidity and mortality and a host of economic, interpersonal, and societal problems. Although until recently the only genes established to affect risk for AD were those encoding several alcohol metabolizing enzymes, there are now several other genes that can be regarded as confirmed risk loci, discovered through linkage and candidate gene association studies. While the mechanism of action of the effects of alcohol-metabolizing enzymes on AD risk is thought to be well understood, we are still in the early stages of understanding the physiology of other risk loci. Further, it is clear that only a small number of the many genes that influence risk for AD have been identified. Newer methodologies (e.g., genomewide association, study of copy number variation, and deep sequencing of candidate loci to identify rare risk variants) that have improved our understanding of other complex traits hold the promise of identifying a greater set of AD susceptibility loci.},

abstract = {Children who have been diagnosed with any one developmental disorder are very likely to meet diagnostic criteria for some other developmental disorder. Although comorbidity has long been acknowledged in childhood disorders, little is understood about the mechanisms that are responsible for the high level of comorbidity. In a series of studies, we have investigated the link between sensory-motor deficits and developmental disorders. Poor sensory-motor integration has long been implicated as a cause of motor problems in developmental disorders such as developmental coordination disorder (DCD), and our recent research has also investigated sensory-motor deficits in children with attention deficit hyperactivity disorder (ADHD) and autistic disorder. Based on a critical examination of relevant literature and some of our recent research findings, we argue that the importance of poor sensory-motor functioning in discriminating children with different disorders has been underestimated. Poor sensory-motor coordination appears to be linked to DCD, but not ADHD. Also, sensory-motor deficits in children with DCD and autistic disorder may provide insight into some of the social difficulties found in these groups of children. This research will increase our understanding of why children with one developmental disorder typically also have problems in other areas.},

title = {Assessment of patient-reported outcomes in clinical trials: the example of health-related quality of life},
abstract = {As the patient is the primary recipient of treatment, there is a need to recognize and value the patient's perception of change in response to treatment in clinical trials. A new outcomes classification, patient-reported outcomes (PROs), has been proposed by regulators. The PROs are used as an umbrella term and include, for example measures of subjective symptoms, health-related quality of life (HRQL) and treatment satisfaction. In this sense, the PROs are unique and complementary indicators of disease activity as well as of treatment efficacy. Frequently, pharmaceutical companies desire to include PRO benefits in the product label in order to reach a broad range of customers, including prescribers as well as patients. Therefore such information must be based on results that are scientifically valid. The measurement strategy, i.e. the thinking about and decision-making related to PRO and HRQL evaluations, needs to be explicit for clinical trials. First of all it is necessary to specify and provide the rationale for measuring the PROs. Similarly, the reason for selecting particular instruments should be stated and, for the selected instruments, the psychometric evidence should be summarized. The key PRO domains must be prespecified and evidence of their importance to patients should be provided. The research question under study and potential claims need to be clearly delineated. Hence, instrument selection is a key initial step for planning successful and scientifically adequate clinical trials intended to support labelling and promotional claims of PRO benefits to patients. The scientific criteria and design issues of clinical trials are the same for clinical and PRO endpoints. However, important issues of particular relevance to PRO assessments, such as missing values, multiple outcomes, and the statistical analysis, require careful attention. The thinking and planning involved in developing the PRO component of the clinical trial need to be articulated. Successful evaluation of PROs in clinical trials relies on careful planning provided the treatment shows sufficient effectiveness.},

title = {Depression and quality of life: results of a follow-up study},
abstract = {BACKGROUND: Although there is sufficient evidence that the quality of life of people suffering from depression is reduced hardly anything is known about their quality of life after the remission of a depressive episode. AIMS: We therefore set out to study the quality of life of patients with depression (ICD-10 F32, F33) one, four and seven months after discharge from hospital. For comparison, a random sample of the general population was studied in addition. METHOD: Quality of life was assessed by means of the WHOQOL-100, a self-administered questionnaire developed by WHO. RESULTS: Although, shortly after discharge, quality of life of patients whose depression remitted was better than that of patients with persisting depression it was still slightly worse than that of the general population. During the subsequent six months, there was no further improvement of quality of life, i.e. even at the end of the follow-up period there was a slight lack of quality of life, especially as concerns the level of independence, spirituality/religion/personal beliefs and physical health. CONCLUSIONS: Thus, what already had been reported based on the objective assessment of quality of life, namely that depression implies a persisting impairment of social functioning and living conditions, can be replicated to some extent from the point of view of the patients themselves.},

title = {Strategies for selecting subsets of single-nucleotide polymorphisms to genotype in association studies},
abstract = {In genetic association studies, linkage disequilibrium (LD) within a region can be exploited to select a subset of single-nucleotide polymorphisms (SNPs) to genotype with minimal loss of information. A novel entropy-based method for selecting SNPs is proposed and compared to an existing method based on the coefficient of determination (R2) using simulated data from Genetic Analysis Workshop 14. The effect of the size of the sample used to investigate LD (by estimating haplotype frequencies) and hence select the SNPs is also investigated for both measures. It is found that the novel method and the established method select SNP subsets that do not differ greatly. The entropy-based measure may thus have value because it is easier to compute than R2. Increasing the sample size used to estimate haplotype frequencies improves the predictive power of the subset of SNPs selected. A smaller subset of SNPs chosen using a large initial sample to estimate LD can in some instances be more informative than a larger subset chosen based on poor estimates of LD (using a small initial sample). An initial sample size of 50 individuals is sufficient in most situations investigated, which involved selection from a set of 7 SNPs, although to select a larger number of SNPs, a larger initial sample size may be required.},

abstract = {A debate has emerged as to whether recognition of emotional stimuli is more accurate or more biased than recognition of nonemotional stimuli. Teasing apart changes in accuracy versus changes in bias requires a measurement model. However, different models have been adopted by different researchers, and this has contributed to the current debate. In this article, different measurement models are discussed, and the signal detection model that is most appropriate for recognition is adopted to investigate the effects of valence and arousal on recognition memory performance, using receiver operating characteristic analyses. In addition, complementary two-alternative forced choice experiments were conducted in order to generalize the empirical findings and interpret them under a relatively relaxed set of measurement assumptions. Across all experiments, accuracy was greater for highly valenced stimuli and stimuli with high arousal value. In addition, a bias to endorse positively valenced stimuli was observed. These results are discussed within an adaptive memory framework that assumes that emotion plays an important role in the allocation of attentional resources.},

title = {Autism genetics: emerging data from genome-wide copy-number and single nucleotide polymorphism scans},
abstract = {Autism and related traits are highly heritable but cannot be explained by currently known genetic risk factors. Therefore, the advent of genome-wide single nucleotide polymorphism (SNP) and copy number variant (CNV) microarray technologies heralded identification of additional autism loci. CNVs associated with autism seem to show variable expressivity, also leading to other phenotypes, such as schizophrenia, mental retardation/developmental delay and epilepsy. Initial genome-wide SNP-association studies have each identified a single novel associated locus with modest effect. Based on the lessons from other complex common disease, larger sample sizes and meta-analyses are likely to identify additional SNP loci, and the genes implicated may act on multiple related disorders. Even if common alleles or rare variants hold little predictive value, neurodevelopmental pathways disrupted in autism may be identified. Future research might yet uncover common CNV risk loci and rare single nucleotide risk alleles, which are currently difficult to detect. The genetic architecture and phenotypic heterogeneity identified so far suggest additional approaches, such as population-based research and study of relevant neurobiological endophenotypes.},

abstract = {OBJECTIVE: To apply Rasch measurement to develop a rule for clinical interpretation of the Observer Scar Assessment Scale (OSAS) to help surgeons judge reported sum scores clinically. STUDY DESIGN AND SETTING: We used cross-sectional data of a multicenter randomized clinical trial for the treatment of nontuberculous cervicofacial lymphadenitis in children. Rasch analysis was used on the OSAS scores obtained from scar photographs of 100 children after surgical or antibiotic treatment. RESULTS: Rasch analysis showed that all OSAS item rating scales needed revision and weighting. After doing so, raw scale scores could be converted into quantitative interval scale-based measures of scar quality. The clinical interpretation of the OSAS was clearly improved by the revised scoring. By using the Rasch-modeled item and person measures, the most likely OSAS score patterns associated with the revised OSAS sum scores could be determined. CONCLUSIONS: The Rasch analysis improved the measurement properties and clinical interpretability of the OSAS instrument.},

abstract = {Recent advances of information technology in biomedical sci- ences and other applied areas have created numerous large diverse data sets with a high dimensional feature space, which provide us a tremendous amount of information and new opportunities for improving the quality of human life. Meanwhile, great challenges are also created driven by the continuous arrival of new data that requires researchers to convert these raw data into scientific knowledge in order to benefit from it. Association studies of complex diseases using SNP data have become more and more popular in biomedical research in recent years. In this paper, we present a review of recent statistical advances and challenges for analyzing correlated high dimensional SNP data in genomic association studies for complex dis- eases. The review includes both general feature reduction approaches for high dimensional correlated data and more specific approaches for SNPs data, which include unsupervised haplotype mapping, tag SNP selection, and supervised SNPs selection using statistical testing/scoring, statistical modeling and machine learning methods with an emphasis on how to iden- tify interacting loci.},

Within-population differences among individuals account for 93 to 95% of genetic variation; differences among major groups constitute only 3 to 5%. Nevertheless, without using prior information about the origins of individuals, we identified six main genetic clusters, five of which correspond to major geographic regions, and subclusters that often correspond to individual populations. General agreement of genetic and predefined populations suggests that self-reported ancestry can facilitate assessments of epidemiological risks but does not obviate the need to use genetic information in genetic association studies.},

title = {A new multitest correction (SGoF) that increases its statistical power when increasing the number of tests},
abstract = {BACKGROUND: The detection of true significant cases under multiple testing is becoming a fundamental issue when analyzing high-dimensional biological data. Unfortunately, known multitest adjustments reduce their statistical power as the number of tests increase. We propose a new multitest adjustment, based on a sequential goodness of fit metatest (SGoF), which increases its statistical power with the number of tests. The method is compared with Bonferroni and FDR-based alternatives by simulating a multitest context via two different kinds of tests: 1) one-sample t-test, and 2) homogeneity G-test. RESULTS: It is shown that SGoF behaves especially well with small sample sizes when 1) the alternative hypothesis is weakly to moderately deviated from the null model, 2) there are widespread effects through the family of tests, and 3) the number of tests is large. CONCLUSION: Therefore, SGoF should become an important tool for multitest adjustment when working with high-dimensional biological data.},

abstract = {OBJECTIVES: To discover what types of scientific misconduct are most likely to influence the results of a clinical trial. DESIGN: Delphi survey of expert opinion with three rounds of consultation. SETTING: Non-industry clinical trial "community". PARTICIPANTS: Experts identified from invitees to a previous MRC consultation on clinical trials. 32 out of the 40 experts approached agreed to participate. RESULTS: We identified thirteen forms of scientific misconduct for which there was majority agreement (>50%) that they would be likely or very likely to distort the results and majority agreement (>50%) that they would be likely or very likely to occur. Of these, the over-interpretation of 'significant' findings in small trials, selective reporting and inappropriate subgroup analyses were the main themes. CONCLUSIONS: According to this expert group, the most important forms of scientific misconduct in clinical trials are selective reporting and the opportunistic use of the play of chance. Data fabrication and falsification were not rated highly because it was considered that these were unlikely to occur. Registration and publication of detailed clinical trial protocols could make an important contribution to preventing scientific misconduct.},

abstract = {In this rejoinder, we respond to comments by Lynn, Rushton, and Templer on our previous paper in which we criticized the use of national IQs in studies of evolutionary theories of race differences in intelligence. We reiterate that because of the Flynn Effect and psychometric issues, national IQs cannot be taken to reflect populations' levels of g as fixed since the last ice age. We argue that the socio-cultural achieve- ments of peoples of Mesopotamia and Egypt in 3000 B.C. stand in stark contrast to the current low level of national IQ of peoples of Iraq and Egypt and that these ancient achievements appear to contradict evo- lutionary accounts of differences in national IQ. We argue that race differences in brain size, even if these were entirely of genetic origin, leave unexplained 91--95% of the black-white IQ gap. We highlight addi- tional problems with hypotheses raised by Rushton and Templer. National IQs cannot be viewed solely in evolutionary terms but should be considered in light of global differences in socio-economic develop- ment, the causes of which are unknown.},

These are the model's (a) inability to address core constructs of personality functioning beyond the level of traits; (b) limitations with respect to the prediction of specific behavior and the adequate description of persons' lives; (c) failure to provide compelling causal explanations for human behavior and experience; (d) disregard of the contextual and conditional nature of human experience; (e) failure to offer an attractive program for studying personality organization and integration; and (f) reliance on simple, noncontingent, and implicitly comparative statements about persons. The five-factor model is essentially a "psychology of the stranger," providing information about persons that one would need to know when one knows nothing else about them. It is argued that because of inherent limitations, the Big Five may be viewed as one important model in personality studies but not the integrative model of personality.},

title = {Five-Factor Model personality profiles of drug users},
abstract = {BACKGROUND: Personality traits are considered risk factors for drug use, and, in turn, the psychoactive substances impact individuals' traits. Furthermore, there is increasing interest in developing treatment approaches that match an individual's personality profile. To advance our knowledge of the role of individual differences in drug use, the present study compares the personality profile of tobacco, marijuana, cocaine, and heroin users and non-users using the wide spectrum Five-Factor Model (FFM) of personality in a diverse community sample. METHOD: Participants (N = 1,102; mean age = 57) were part of the Epidemiologic Catchment Area (ECA) program in Baltimore, MD, USA. The sample was drawn from a community with a wide range of socio-economic conditions. Personality traits were assessed with the Revised NEO Personality Inventory (NEO-PI-R), and psychoactive substance use was assessed with systematic interview. RESULTS: Compared to never smokers, current cigarette smokers score lower on Conscientiousness and higher on Neuroticism. Similar, but more extreme, is the profile of cocaine/heroin users, which score very high on Neuroticism, especially Vulnerability, and very low on Conscientiousness, particularly Competence, Achievement-Striving, and Deliberation. By contrast, marijuana users score high on Openness to Experience, average on Neuroticism, but low on Agreeableness and Conscientiousness. CONCLUSION: In addition to confirming high levels of negative affect and impulsive traits, this study highlights the links between drug use and low Conscientiousness. These links provide insight into the etiology of drug use and have implications for public health interventions.},

abstract = {The concept of mediation has broad applications in medical health studies. Although the statistical assessment of a mediational effect under the normal assumption has been well established in linear structural equation models (SEM), it has not been extended to the general case where normality is not a usual assumption. In this paper, we propose to extend the definition of mediational effects through causal inference. The new definition is consistent with that in linear SEM and does not rely on the assumption of normality. Here, we focus our attention on the logistic mediation model, where all variables involved are binary. Three approaches to the estimation of mediational effects-Delta method, bootstrap, and Bayesian modelling via Monte Carlo simulation are investigated. Simulation studies are used to examine the behaviour of the three approaches. Measured by 95 per cent confidence interval (CI) coverage rate and root mean square error (RMSE) criteria, it was found that the Bayesian method using a non-informative prior outperformed both bootstrap and the Delta methods, particularly for small sample sizes. Case studies are presented to demonstrate the application of the proposed method to public health research using a nationally representative database. Extending the proposed method to other types of mediational model and to multiple mediators are also discussed.},

title = {Latent variables and structural equation models for longitudinal relationships: an illustration in nutritional epidemiology},
abstract = {Background
The use of structural equation modeling and latent variables remains uncommon in epidemiology despite its potential usefulness. The latter was illustrated by studying cross-sectional and longitudinal relationships between eating behavior and adiposity, using four different indicators of fat mass.
Methods
Using data from a longitudinal community-based study, we fitted structural equation models including two latent variables (respectively baseline adiposity and adiposity change after 2 years of follow-up), each being defined, by the four following anthropometric measurement (respectively by their changes): body mass index, waist circumference, skinfold thickness and percent body fat. Latent adiposity variables were hypothesized to depend on a cognitive restraint score, calculated from answers to an eating-behavior questionnaire (TFEQ-18), either cross-sectionally or longitudinally.
Results
We found that high baseline adiposity was associated with a 2-year increase of the cognitive restraint score and no convincing relationship between baseline cognitive restraint and 2-year adiposity change could be established.
Conclusions
The latent variable modeling approach enabled presentation of synthetic results rather than separate regression models and detailed analysis of the causal effects of interest. In the general population, restrained eating appears to be an adaptive response of subjects prone to gaining weight more than as a risk factor for fat-mass increase.},

title = {Protocol for a randomised controlled trial investigating the effectiveness of an online e health application for the prevention of Generalised Anxiety Disorder},
abstract = {ABSTRACT: BACKGROUND: Generalised Anxiety Disorder (GAD) is a highly prevalent psychiatric disorder. Effective prevention in young adulthood has the potential to reduce the prevalence of the disorder, to reduce disability and lower the costs of the disorder to the community. The present trial (the WebGAD trial) aims to evaluate the effectiveness of an evidence-based online prevention website for GAD. METHODS: The principal clinical question under investigation is the effectiveness of an online GAD intervention (E-couch) using a community-based sample. We examine whether the effect of the intervention can be maximised by either human support, in the form of telephone calls, or by automated support through emails. The primary outcome will be a reduction in symptoms on the GAD-7 in the active arms relative to the non active intervention arms. DISCUSSION: The WebGAD trial will be the first to evaluate the use of an internet-based cognitive behavioural therapy (CBT) program contrasted with a credible control condition for the prevention of GAD and the first formal RCT evaluation of a web-based program for GAD using community recruitment. In general, internet-based CBT programs have been shown to be effective for the treatment of other anxiety disorders such as Post Traumatic Stress Disorder, Social Phobia, Panic Disorder and stress in clinical trials; however there is no evidence for the use of internet CBT in the prevention of GAD. Given the severe shortage of therapists identified in Australia and overseas, and the low rates of treatment seeking in those with a mental illness, the successful implementation of this protocol has important practical outcomes. If found to be effective, WebGAD will provide those experiencing GAD with an easily accessible, free, evidence-based prevention tool which can be promoted and disseminated immediately.

abstract = {In modern whole-genome scans, the use of stringent thresholds to control the genome-wide testing error distorts the estimation process, producing estimated effect sizes that may be on average far greater in magnitude than the true effect sizes. We introduce a method, based on the estimate of genetic effect and its standard error as reported by standard statistical software, to correct for this bias in case-control association studies. Our approach is widely applicable, is far easier to implement than competing approaches, and may often be applied to published studies without access to the original data. We evaluate the performance of our approach via extensive simulations for a range of genetic models, minor allele frequencies, and genetic effect sizes. Compared to the naive estimation procedure, our approach reduces the bias and the mean squared error, especially for modest effect sizes. We also develop a principled method to construct confidence intervals for the genetic effect that acknowledges the conditioning on statistical significance. Our approach is described in the specific context of odds ratios and logistic modeling but is more widely applicable. Application to recently published data sets demonstrates the relevance of our approach to modern genome scans.},

Given family relationships of varying complexity embedded in short stories, testees had to logically conclude the correct relationship between two individuals within a family. Using empirical data, the linear logistic test model (LLTM; Fischer, 1972), a special case of the Rasch model, was used to test the construct validity of the test: The hypothetically assumed basic cognitive operations had to explain the Rasch model's item difficulty parameters. After being shaped in LLTM's matrices of weights ((qij)), none of these operations were corroborated by means of the Ander- sen's Likelihood Ratio Test.},

As a direct consequence, the Rasch measurement approach to the construction and monitoring of variables is sensitive to the issues raised in Messick's (1995) broader conception of construct validity. The theory / practice dialectic (Bond {\&} Fox, 2001) ensures that validity is foremost in the mind of those developing measures and that genuine scientific measurement is foremost in the minds of those who seek valid outcomes from assessment. Failures of invariance, such as those referred to as DIF, should alert researchers to the need to modify assessment procedures or the substantive theory under investigation, or both.},

abstract = {Genome-wide association studies (GWAS) have been fruitful in identifying disease susceptibility loci for common and complex diseases. A remaining question is whether we can quantify individual disease risk based on genotype data, in order to facilitate personalized prevention and treatment for complex diseases. Previous studies have typically failed to achieve satisfactory performance, primarily due to the use of only a limited number of confirmed susceptibility loci. Here we propose that sophisticated machine-learning approaches with a large ensemble of markers may improve the performance of disease risk assessment. We applied a Support Vector Machine (SVM) algorithm on a GWAS dataset generated on the Affymetrix genotyping platform for type 1 diabetes (T1D) and optimized a risk assessment model with hundreds of markers. We subsequently tested this model on an independent Illumina-genotyped dataset with imputed genotypes (1,008 cases and 1,000 controls), as well as a separate Affymetrix-genotyped dataset (1,529 cases and 1,458 controls), resulting in area under ROC curve (AUC) of approximately 0.84 in both datasets. In contrast, poor performance was achieved when limited to dozens of known susceptibility loci in the SVM model or logistic regression model. Our study suggests that improved disease risk assessment can be achieved by using algorithms that take into account interactions between a large ensemble of markers. We are optimistic that genotype-based disease risk assessment may be feasible for diseases where a notable proportion of the risk has already been captured by SNP arrays.},

abstract = {Missing single nucleotide polymorphisms (SNPs) are quite common in ge- netic association studies. Subjects with missing SNPs are often discarded in analyses, which may seriously undermine the inference of SNP-disease associa- tion. In this article, we compare two haplotype-based imputation approaches and one regression tree-based imputation approach for association studies. The goal is to assess the imputation accuracy, and to evaluate the impact of imputa- tion on parameter estimation. Haplotype-based approaches build on haplotype reconstruction by the expectation-maximization (EM) algorithm or a weighted EM (WEM) algorithm, depending on whether case-control status is taken into account. The tree-based approach uses a Gibbs sampler to iteratively sample from a full conditional distribution, which is obtained from the classification and regression tree (CART) algorithm. We employ a standard multiple imputation procedure to account for the uncertainty of imputation. We apply the methods to simulated data as well as a case-control study on developmental dyslexia. Our results suggest that imputation generally improves over the standard practice of ignoring missing data in terms of bias and efficiency. The haplotype-based approaches slightly outperform the tree-based approach when there are a small number of SNPs in linkage disequilibrium (LD), but the latter has a computa- tional advantage. Finally, we demonstrate that utilizing the disease status in imputation helps to reduce the bias in the subsequent parameter estimation.},

abstract = {OBJECTIVE:: Adult-onset schizophrenia has repeatedly been associated with disturbances in the temporal lobes and alterations in cortical folding, which are thought to reflect neurodevelopmental impairment. Early-onset schizophrenia (EOS; onset before 18 years) is considered to involve even more pronounced neurodevelopmental deviance across a wide range of brain structural measures. We hypothesized that overall alteration of cortical folding also applies to EOS, and EOS involves prominent structural aberrations in superior temporal and collateral sulci. METHOD:: Magnetic resonance T1 images of 51 patients with EOS and 59 healthy participants were investigated. A fully automated method was applied to the images to extract, label, and measure the sulcus area in the whole cortex. Cortical folding was assessed by computing global sulcal indices (the ratio between total sulcal area and total outer cortex area) for each hemisphere and local sulcal indices (the ratio between the area of labeled sulcus and total outer cortex area in the corresponding hemisphere) for superior temporal and collateral sulci. RESULTS:: Relative to healthy individuals, patients with EOS had significantly lower global sulcal indices in both hemispheres and a lower local sulcal index in the left collateral sulcus. CONCLUSIONS:: Reduced hemispheric sulcation appears to be a feature of schizophrenia, irrespective of age at onset. Structural aberration involving the left collateral sulcus may contribute to neurobiological substrate of EOS.},

An active learner may ask queries in the form of unlabeled instances to be labeled by an oracle (e.g., a human annotator). Active learning is well-motivated in many modern machine learning problems, where unlabeled data may be abundant but labels are difficult, time-consuming, or expensive to obtain.
This report provides a general introduction to active learning and a survey of the literature. This includes a discussion of the scenarios in which queries can be formulated, and an overview of the query strategy frameworks proposed in the literature to date. An analysis of the empirical and theoretical evidence for active learning, a summary of several problem setting variants, and a discussion of related topics in machine learning research are also presented.},

title = {Scoring based on item response theory did not alter the measurement ability of EORTC QLQ-C30 scales},
abstract = {BACKGROUND AND OBJECTIVES: Most health-related quality-of-life questionnaires include multi-item scales. Scale scores are usually estimated as simple sums of the item scores. However, scoring procedures utilizing more information from the items might improve measurement abilities, and thereby reduce the needed sample sizes. We investigated whether item response theory (IRT)-based scoring improved the measurement abilities of the EORTC QLQ-C30 physical functioning, emotional functioning, and fatigue scales. METHODS: Using a database of 13,010 subjects we estimated the relative validities of IRT scoring compared to sum scoring of the scales. RESULTS: The mean relative validities were 1.04 (physical), 1.03 (emotional), and 0.97 (fatigue). None of these were significantly larger than 1. Thus, no gain in measurement abilities using IRT scoring was found for these scales. Possible explanations include that the items in the scales are not constructed for IRT scoring and that the scales are relatively short. CONCLUSION: IRT scoring of the three longest EORTC QLQ-C30 scales did not improve measurement abilities compared to the traditional sum scoring of the scales.},
