of anxiety vulnerability through the modification of attentional bias: a real-world study using a home-based cognitive bias modification procedure},
abstract = {Recent laboratory work suggests that biased attentional responding to negative information causally impacts anxiety reactivity to a contrived laboratory stressor. However, it remains unknown whether such attentional bias contributes to real-world anxiety vulnerability. In the present study, the authors addressed this issue by experimentally inducing biased attentional response to emotionally negative stimuli, using a home-based attentional training program and then examining the influence of this attentional manipulation on trait anxiety scores and on state anxiety responses to a subsequent stressful life event. The attentional bias modification procedure was effective in inducing attentional avoidance of negative information. Furthermore, this attentional manipulation served to reduce trait anxiety scores and to attenuate state anxiety responses to the subsequent naturalistic stressor. These findings support the hypotheses that biased attentional responding to emotionally negative information contributes causally to real-world anxiety vulnerability.},

title = {Genome-wide association studies and the genetic dissection of complex traits},
abstract = {The availability of affordable high throughput technology for parallel genotyping has opened the field of genetics to genome-wide association studies (GWAS), and in the last few years hundreds of articles reporting results of GWAS for a variety of heritable traits have been published. What do these results tell us? Although GWAS have discovered a few hundred reproducible associations, this number is underwhelming in relation to the huge amount of data produced, and challenges the conjecture that common variants may be the genetic causes of common diseases. We argue that the massive amount of genetic data that result from these studies remains largely unexplored and unexploited because of the challenge of mining and modeling enormous data sets, the difficulty of using nontraditional computational techniques and the focus of accepted statistical analyses on controlling the false positive rate rather than limiting the false negative rate. In this article, we will review the common approach to analysis of GWAS data and then discuss options to learn more from these data. We will use examples from our ongoing studies of sickle cell anemia and also GWAS in multigenic traits.},

abstract = {MOTIVATION: Many clustering algorithms have been proposed for the analysis of gene expression data, but little guidance is available to help choose among them. We provide a systematic framework for assessing the results of clustering algorithms. Clustering algorithms attempt to partition the genes into groups exhibiting similar patterns of variation in expression level. Our methodology is to apply a clustering algorithm to the data from all but one experimental condition. The remaining condition is used to assess the predictive power of the resulting clusters-meaningful clusters should exhibit less variation in the remaining condition than clusters formed by chance. RESULTS: We successfully applied our methodology to compare six clustering algorithms on four gene expression data sets. We found our quantitative measures of cluster quality to be positively correlated with external standards of cluster quality.},

We recently validated and used the St George's Respiratory Questionnaire to ascertain HRQL in treated TB patients. We appreciate the authors' review of this topic and find from their analysis convincing support for expanding LTBI treatment guidelines. Currently only treatment of latent tuberculosis infection (LTBI) can prevent pulmonary impairment after tuberculosis (PIAT).},

title = {Cross-cultural adaptation of research instruments: language, setting, time and statistical considerations},
abstract = {Background
Research questionnaires are not always translated appropriately before they are used in new temporal, cultural or linguistic settings. The results based on such instruments may therefore not accurately reflect what they are supposed to measure. This paper aims to illustrate the process and required steps involved in the cross-cultural adaptation of a research instrument using the adaptation process of an attitudinal instrument as an example.
Methods
A questionnaire was needed for the implementation of a study in Norway 2007. There was no appropriate instruments available in Norwegian, thus an Australian-English instrument was cross-culturally adapted.
Results
The adaptation process included investigation of conceptual and item equivalence. Two forward and two back-translations were synthesized and compared by an expert committee. Thereafter the instrument was pretested and adjusted accordingly. The final questionnaire was administered to opioid maintenance treatment staff (n=140) and harm reduction staff (n=180). The overall response rate was 84%. The original instrument failed confirmatory analysis. Instead a new two-factor scale was identified and found valid in the new setting.
Conclusions
The failure of the original scale highlights the importance of adapting instruments to current research settings. It also emphasizes the importance of ensuring that concepts within an instrument are equal between the original and target language, time and context. If the described stages in the cross-cultural adaptation process had been omitted, the findings would have been misleading, even if presented with apparent precision. Thus, it is important to
consider possible barriers when making a direct comparison between different nations, cultures and times.},

Surrogate endpoints may occur more frequently than their standard counterparts. For these reasons, it is not surprising that the use of surrogate endpoints in clinical practice is increasing. Building on the seminal work of Prentice(1) and Freedman et al.,(2) Buyse et al. (3) framed the evaluation exercise within a meta-analytic setting, in an effort to overcome difficulties that necessarily surround evaluation efforts based on a single trial. In this article, we review the meta-analytic approach for continuous outcomes, discuss extensions to non-normal and longitudinal settings, as well as proposals to unify the somewhat disparate collection of validation measures currently on the market. Implications for design and for predicting the effect of treatment in a new trial, based on the surrogate, are discussed. A case study in schizophrenia is analysed.},

abstract = {OBJECTIVE: Problems arising with the estimation of sensitivity and specificity when two imperfect diagnostic tests are applied are widely discussed. Effects on the estimation of prevalence may be of importance as well. Different methods of dealing with two or more imperfect tests and unknown reference standard are contrasted with regard to their implications on prevalence estimation: discrepant analysis, composite reference standards, and latent class models. STUDY DESIGN AND SETTING: Prospective epidemiological multicenter study to determine the prevalence of respiratory syncytial virus in children with lower respiratory tract infections. A subsample of 1,003 patients from a hospital population and from a practice population is considered. Virus isolation, polymerase chain reaction, and rapid antigen test had been applied. RESULTS: Prevalence estimates obtained under various assumptions ranged from 0.263 to 0.386 in the hospital population and from 0.214 to 0.277 in the practice population. CONCLUSION: Estimation procedures involving a resolver test applied to some but not all cells are at risk of introducing a serious bias in prevalence estimation as well as in the estimation of test accuracy parameters. Estimation via latent class modeling may be more useful, but care should be taken regarding the underlying assumptions.},

title = {An Introduction to Recursive Partitioning},
abstract = {Recursive partitioning methods have become popular and widely used tools for non- parametric regression and classification in many scientific fields. Especially random forests, that can deal with large numbers of predictor variables even in the presence of complex interactions, have been applied successfully in genetics, clinical medicine and bioinformatics within the past few years.
High dimensional problems are common not only in genetics, but also in some areas of psychological research, where only few subjects can be measured due to time or cost constraints, yet a large amount of data is generated for each subject. Random forests have been shown to achieve a high prediction accuracy in such applications, and provide descriptive variable importance measures reflecting the impact of each variable in both main effects and interactions.
The aim of this work is to introduce the principles of the standard recursive partitioning methods as well as recent methodological improvements, to illustrate their usage for low and high dimensional data exploration, but also to point out limitations of the methods and potential pitfalls in their practical application.
Application of the methods is illustrated using freely available implementations in the R system for statistical computing.},

title = {Using patient-reported outcomes in clinical practice: challenges and opportunities},
abstract = {PURPOSE: Introduce and explore issues at an international conference about the use of patient-reported outcomes (PROs) in clinical practice. METHODS: Review of salient literature, clinical and personal experiences, conference presentations and discussions, and post-conference comments from outside experts. RESULTS: PROs (information from patients about a health condition and its management) have been assessed through self-reports for at least four decades. Traditional applications are in clinical and health services research. Uses in clinical practice, although increasing, are less common and more challenging. PROs can enhance the understanding of patients' experiences and responses to therapy and inform clinical practice. CONCLUSIONS: We pose and discuss four main questions: (1) Will clinicians accept PRO measures? (2) Will clinicians use PRO measures? (3) Will measuring PROs actually improve those outcomes? (4) Will PROs be perceived as having other, less salutary purposes? A patient-centered perspective on PRO measurement presents issues about the extent to which PROs can accurately capture patient experiences and assess psychosocial and environmental factors that influence communication with clinicians and eventual outcomes. We end with comments about the intersection of PROs and bioethics, noting contributions that PROs may make to beneficence, patient autonomy, and distributive justice.},

title = {The use of linear mixed models to estimate variance components from data on twin pairs by maximum likelihood},
abstract = {It is shown that maximum likelihood estimation of variance components from twin data can be parameterized in the framework of linear mixed models. Standard statistical packages can be used to analyze univariate or multivariate data for simple models such as the ACE and CE models. Furthermore, specialized variance component estimation software that can handle pedigree data and user-defined covariance structures can be used to analyze multivariate data for simple and complex models, including those where dominance and/or QTL effects are fitted. The linear mixed model framework is particularly useful for analyzing multiple traits in extended (twin) families with a large number of random effects.},

title = {A model selection approach to analysis of variance and covariance},
abstract = {An alternative to analysis of variance is a model selection approach where every partition of the treatment means into clusters with equal value is treated as a separate model. The null hypothesis that all treatments are equal corresponds to the partition with all means in a single cluster. The alternative hypothesis correspond to the set of all other partitions of treatment means. A model selection approach can also be used for a treatment by covariate interaction, where the null hypothesis and each alternative correspond to a partition of treatments into clusters with equal covariate effects. We extend the partition-as-model approach to simultaneous inference for both treatment main effect and treatment interaction with a continuous covariate with separate partitions for the intercepts and treatment-specific slopes. The model space is the Cartesian product of the intercept partition and the slope partition, and we develop five joint priors for this model space. In four of these priors the intercept and slope partition are dependent. We advise on setting priors over models, and we use the model to analyze an orthodontic data set that compares the frictional resistance created by orthodontic fixtures.},

In this functional magnetic resonance imaging (fMRI) twin study, we found a significant genetic influence on brain activation in neural networks supporting digit working memory tasks. Participants activating frontal-parietal networks responded faster than individuals relying more on language-related brain networks. There were genetic influences on brain activation in language-relevant brain circuits that were atypical for numerical working memory tasks as such. This suggests that differences in cognition might be related to brain activation patterns that differ qualitatively among individuals.},

title = {Scales for evaluating depressive symptoms in Chinese patients with schizophrenia},
abstract = {There have been few studies evaluating depressive symptoms in Chinese patients with schizophrenia. Thus, we planned to compare the diagnostic validity of 4 commonly used assessment scales for depression in schizophrenia in China. The association between different depression scales and between depression scales and negative symptoms were also studied. The study population consisted of 101 inpatients meeting the DSM-IV criteria for schizophrenia. Depression in the study subjects was defined by the DSM-IV criteria for a major depressive episode. The negative subscale of the PANSS was used to assess the negative symptoms in schizophrenia. The following 4 depression scales were assessed for their diagnostic validity as measures of depressive disorder in schizophrenia: the Calgary Depression Scale for Schizophrenia (CDSS), the Montgomery-Asberg Depression Rating Scale (MADRS), the Hamilton Rating Scale for Depression (HAM-D), and the depression subscale of the PANSS (PANSS-D). The depression scales were found to be highly intercorrelated with each other. Of the 4 depression scales studied, only CDSS can discriminate between depression and a PANSS negative symptoms subscale score or negative item scores. The areas under the receiver operating characteristic curves of the CDSS, HAM-D, MARDS, and PANSS-D were 0.954, 0.881, 0.828, and 0.897, respectively. The area under the receiver operating characteristic curve of the CDSS was significantly greater than those of the HAM-D, the MARDS, and the PANSS-D. Our study suggests that the CDSS may provide optimal assessment of depression in patients with schizophrenia.},

abstract = {CONTEXT: The evidence that breastfeeding improves cognitive development is based almost entirely on observational studies and is thus prone to confounding by subtle behavioral differences in the breastfeeding mother's behavior or her interaction with the infant. OBJECTIVE: To assess whether prolonged and exclusive breastfeeding improves children's cognitive ability at age 6.5 years. DESIGN: Cluster-randomized trial, with enrollment from June 17, 1996, to December 31, 1997, and follow-up from December 21, 2002, to April 27, 2005. SETTING: Thirty-one Belarussian maternity hospitals and their affiliated polyclinics. PARTICIPANTS: A total of 17,046 healthy breastfeeding infants were enrolled, of whom 13,889 (81.5%) were followed up at age 6.5 years. INTERVENTION: Breastfeeding promotion intervention modeled on the Baby-Friendly Hospital Initiative by the World Health Organization and UNICEF. MAIN OUTCOME MEASURES: Subtest and IQ scores on the Wechsler Abbreviated Scales of Intelligence, and teacher evaluations of academic performance in reading, writing, mathematics, and other subjects. RESULTS: The experimental intervention led to a large increase in exclusive breastfeeding at age 3 months (43.3% for the experimental group vs 6.4% for the control group; P < .001) and a significantly higher prevalence of any breastfeeding at all ages up to and including 12 months. The experimental group had higher means on all of the Wechsler Abbreviated Scales of Intelligence measures, with cluster-adjusted mean differences (95% confidence intervals) of +7.5 (+0.8 to +14.3) for verbal IQ, +2.9 (-3.3 to +9.1) for performance IQ, and +5.9 (-1.0 to +12.8) for full-scale IQ. Teachers' academic ratings were significantly higher in the experimental group for both reading and writing. CONCLUSION: These results, based on the largest randomized trial ever conducted in the area of human lactation, provide strong evidence that prolonged and exclusive breastfeeding improves children's cognitive development.

abstract = {Clinimetrics and psychometrics, two accepted methods for developing multiitem health measurement scales, have fundamentally different aims and methods that have seldom been compared and never prospectively. The purpose of this study was to determine whether these two methodologies provided comparable scales in the development of an upper extremity disability measure. Psychometric analysis involved field testing a 70-item questionnaire on 407 patients. Equidiscriminatory item total correlation (EITC) was used to select the top 30 items. Clinimetric testing used the mean importance and severity ratings of the 70 items by 76 patients to select the top 30 items. Clinimetric and psychometric analyses were performed independently. Cronbach's alpha was 0.97 for the top 30 items selected by EITC and 0.96 for the items selected based on patient's ratings. The two scales (after clinician modification to improve face validity) shared 16 items in common (P=0.10). The intraclass correlation coefficient of the patient scores on the two 30-item scales was 0.93 before clinician input and 0.97 after. The mean (and standard deviation) difference between scales was 9.1 (8.8) before and 1.7 (5.2) after clinician input. A scale developed with a clinimetric strategy can measure a complex (so-called heterogeneous) clinical phenomenon (thought to be composed of several patient attributes) but still fulfill psychometric criteria for "homogeneity." Thus, these strategies for the development of health measurement scales, which have been considered potentially opposite or conflicting, may be complementary.},

abstract = {OBJECTIVE: This study compared self-reported fatigue between 7-day and 4-week time frames and explored factors that affect patients' responses. STUDY DESIGN AND SETTING: Two hundred and sixteen cancer patients completed either 7-day or 4-week version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Cochran-Mantel-Haenszel statistics and Cochran-Armitage trend tests were used to assess the association between time frame and item scores. Information function curves at both item and scale levels were depicted to evaluate the precision along the fatigue continuum. Differential item functioning (DIF) was used to examine the stability of the psychometric properties between time frames. RESULTS: Time frame did not influence patients' item responses. Examination of information function curves at item level did not clearly favor either time frame. At the scale level, the 7-day time frame was slightly more precise overall than the 4-week time frame. No item demonstrated DIF between time frames. Neither gender nor fatigue severity had an impact on above results. CONCLUSION: This study suggests 7-day and 4-week time frame are equally appropriate in measuring fatigue, preference might be given to the more informative 7-day time frame. However, substantive considerations regarding the appropriate time frame should outweigh statistical ones.},

Readily available software is used to test whether the results of PA are sensitive to several distributional prescriptions in the literature regarding the rank, normality, mean, variance, and range of simulated data on a portion of the National Comorbidity Survey Replication (Pennell et al., 2004) by varying the distributions in each PA. The results of PA were found not to vary by distributional assumption. The conclusion is that PA may be reliably performed with the computationally simplest distributional assumptions about the simulated data.},

abstract = {The emotions and attitudes of mothers towards their infants are crucial for the child's well-being and development. Some mothers experience a delay in the onset of maternal affection after childbirth and occasionally a longer lasting failure to bond will ensue. Little is known about the precise prevalence of these difficulties, how they relate to maternal mental health, how they develop over time and what their biological and psychosocial correlates are. In research studies the mother-infant relationship has traditionally been assessed using observational methods but these are time consuming and not suited for screening in clinical practice. Two self-rating instruments have recently been developed to assess maternal bonding. Both can be used in large samples of recently delivered mothers including those suspected to be at high risk of bonding disorders. In this study, the psychometric properties of the 8-item Mother-to-Infant Bonding Scale (MIB) and the 25-item screening questionnaire for mother-infant bonding disorders, namely the Postpartum Bonding Questionnaire (PBQ), were examined in a sample of first-time mothers in order to establish their reliability and validity. Ninety-six women completed the MIB, PBQ and the Kennerley Blues Scale on day 2-4 postpartum. Both bonding instruments demonstrated acceptable reliability and reasonable validity, with the exception of the PBQ subscale of risk of abuse.},

We found that risk propensity (risk taking, sensation seeking, and sensitivity to reward) and empathy related to ERN amplitude (negatively and positively, respectively) but not to each other or to behavioral measures of response time, accuracy, and post-error slowing. They accounted for separate sources of variance in the ERN amplitude, suggesting that there are multiple routes to activation of its generator in the anterior cingulate. Impulsivity and sensitivity to punishment were unrelated to the ERN. The present study provides support that risk-taking traits and empathy affect anterior cingulate responsiveness to errors, and the ERN reflects the influence of the extent of individuals' concern with the outcome of events.},

The statistical analysis of these studies combines two difficulties: the choice of the best ordinal model and taking into account correlations for within-subject responses. METHODS: Random-effect models are of particular value in this context and we propose here a fitting strategy. The various ordinal models extended to the case of repeated responses are detailed. We explain how the choice of model constrains the random effect structure. Model selection criteria and goodness-of-fit measures are also presented. These issues are dealt with by using an example of self-reported disability in older women assessed annually over a period of seven years. RESULTS: The proportionality of the odds ratios was validated for the covariables "age" and "gait speed". In contrast the impact of the covariable "pain" differs according to the levels of disability. The restricted partial proportional odds model was found to have a goodness of fit equivalent to the full generalized ordered logit model while the stereotype model appeared to give poorer fit. CONCLUSIONS: The random-effects models presented in this paper allow taking into account the ordinal nature of the outcome in longitudinal studies. Furthermore the impact of the risk factors can be modeled according to the response levels. This approach can be useful for a better understanding of complex processes of evolution.},

abstract = {More than 99.9 % of the sequence is identical when comparing the DNA from two individuals. The remaining 0.1 % is responsible, along with other factors such as the environment, for the risk level of developing complex diseases (such as asthma, diabetes or cancer) or for the different pharmacological response to drugs. Despite the incredible advances in genomics in the past few years, identifying the variants involved remains difficult because of the prodigious amount of information to process. The recent completion of the Haplotype Map of the human genome has raised great hopes in the field as it is expected to help reduce the complexity of association studies and thus accelerate the discovery of genes associated with complex diseases. This review details the rationale behind the HapMap project, gives a summary of the results and also describes potential applications of the Haplotype Map.},

In addition to ordinary Rasch mod- els extended models such as linear logistic test models, (linear) rating scale models and (linear) partial credit models can be estimated. A striking feature of this package is the implementation of conditional maximum likelihood estimation techniques which relate directly to Rasch's original concept of specific objectivity. The mathematical and epistemological benefits of this estimation method are discussed.

title = {A log-linear approach to case-parent-triad data: assessing effects of disease genes that act either directly or through maternal effects and that may be subject to parental imprinting},
abstract = {We describe a log-linear method for analysis of case-parent-triad data, based on maximum likelihood with stratification on parental mating type. The method leads to estimates of association parameters, such as relative risks, for a single allele, and also to likelihood ratio chi2 tests (LRTs) of linkage disequilibrium. Hardy-Weinberg equilibrium need not be assumed. Our simulations suggest that the LRT has power similar to that of the chi2 "score" test proposed by Schaid and Sommer and that both can outperform the transmission/disequilibrium test (TDT), although the TDT can perform better under an additive model of inheritance. Because a restricted version of the LRT is asymptotically equivalent to the TDT, the proposed test can be regarded as a generalization of the TDT. The method that we describe generalizes easily to accommodate maternal effects on risk and, in fact, produces powerful and orthogonal tests of the contribution of fetal versus maternal genetic factors. We further generalize the model to allow for effects of parental imprinting. Imprinting effects can be fitted by a simple, iterative procedure that relies on the expectation-maximization algorithm and that uses standard statistical software for the maximization steps. Simulations reveal that LRT tests for detection of imprinting have very good operating characteristics. When a single allele is under study, the proposed method can yield powerful tests for detection of linkage disequilibrium and is applicable to a broader array of causal scenarios than is the TDT.},

This approach views classical test theory as a very general version of IRT, and the commonly used IRT models as detailed elaborations of CTT for special purposes. We then use this approach to CTT to derive some general results regarding the prediction of the true-score of a test from an observed score on that test as well from an observed score on a different test. This leads us to a new view of linking tests that were not developed to be linked to each other. In addition we propose true-score prediction analogues of the Dorans and Holland measures of the population sensitivity of test linking functions. We illustrate the accuracy of the first-order theory using simulated data from the Rasch model, and illustrate the effect of population differences using a set of real data.},

title = {QTL analysis of multiple behavioral measures of anxiety in mice},
abstract = {In a test battery consisting of an open-field arena, a light-dark box, a mirror-chamber box, an elevated plus maze, and an elevated square maze, 1,671 mice were tested, generating over 100 putative measures of anxiety in rodents. Quantitative trait loci (QTL) analysis was carried out on all measures, plus composite measures and phenotypic factor scores. Significant LOD scores were found for QTL on 17 chromosomes, with large and consistent QTL behavioral effects on chromosomes 1, 4, 7, 8, 14, 15, l8, and X. QTL on chromosomes 4 and 8 largely influence locomotor activity in both home cages and novel environments, whereas QTL on chromosomes 1, 15, and 18 influence anxiety-related behaviors. Five genetically separable, cross-test dimensions of anxiety could be identified: (i) the suppression of locomotor activity in low to moderately anxiogenic regions of the tests; (ii) a shift toward proportionally less time and activity spent in high-anxiogenic test areas; (iii) the suppression of rearing behavior; (iv) increased latency to enter novel areas; (v) increased autonomic responses, as assessed by defecation and urination. Patterns of QTL influence on cross-test composite scores were distinctive. For example, the QTL on chromosome 1 strongly influenced safe-area locomotor activity (LOD = 35) and autonomic responses (LOD = 16), whereas the QTL on chromosome 15 influenced the proportion of activity in high-anxiogenic areas (LOD = 16), latency to enter novel areas (LOD = 36) and rearing behavior (LOD = 57). Phenotypic factor analysis identified factors heavily loaded on single tests, rather than cross-test factors. The use of factor analysis or within-test principal components for data reduction before genetic analysis was less satisfactory than using genetic dissection methods on the original measures and logically derived composites.},

The incidence rate per 10,000 children per year for the combined areas was 8.3 for all children with ASDs, 3.5 for classical childhood autism (CA), and 4.8 for other ASDs. Rates were similar in both areas, despite differences in social deprivation and proportions of ethnic minorities. While rates for classical CA increased by 18% per year, a much larger increase (55% per year) was seen for 'other ASDs', suggesting that clinicians are becoming increasingly able and/or willing to diagnose ASDs in preschool children.},

Across the four demographic variables and the five personality dimensions, we find average correlations of 0.08 with the Big-Five factors and 0.10 with the AVA vectors.

Because individuals with autism experience reduced preparatory activity prior to a voluntary movement, the present study sought to determine whether these anticipatory biases are exhibited by persons with autism. Participants watched a dot move in a circle and pressed the spacebar any time after one revolution. A tone either followed the participants' voluntary movement or was computer generated. Participants in both groups made anticipatory judgements regarding movement initiation ( approximately 100 ms). When the movement and tone occurred together this anticipatory bias was also present, regardless of which event participants focused on. Individuals with autism appear to have access to a similar representation of voluntary movements, however this representation may be more variable.},

title = {Are Extended Twin Family Designs Worth the Trouble? A Comparison of the Bias, Precision, and Accuracy of Parameters Estimated in Four Twin Family Models},
abstract = {The classical twin design (CTD) uses observed covariances from monozygotic and dizygotic twin pairs to infer the relative magnitudes of genetic and environmental causes of phenotypic variation. Despite its wide use, it is well known that the CTD can produce biased estimates if its stringent assumptions are not met. By modeling observed covariances of twins' relatives in addition to twins themselves, extended twin family designs (ETFDs) require less stringent assumptions, can estimate many more parameters of interest, and should produce less biased estimates than the CTD. However, ETFDs are more complicated to use and interpret, and by attempting to estimate a large number of parameters, the precision of parameter estimates may suffer. This paper is a formal investigation into a simple question: Is it worthwhile to use more complex models such as ETFDs in behavioral genetics? In particular, we compare the bias, precision, and accuracy of estimates from the CTD and three increasingly complex ETFDs. We find the CTD does a decent job of estimating broad sense heritability, but CTD estimates of shared environmental effects and the relative importance of additive versus non-additive genetic variance can be biased, sometimes wildly so. Increasingly complex ETFDs, on the other hand, are more accurate and less sensitive to assumptions than simpler models. We conclude that researchers interested in characterizing the environment or the makeup of genetic variation should use ETFDs when possible.},

title = {An integrative modular approach to systematically predict gene-phenotype associations},
abstract = {BACKGROUND: Complex human diseases are often caused by multiple mutations, each of which contributes only a minor effect to the disease phenotype. To study the basis for these complex phenotypes, we developed a network-based approach to identify coexpression modules specifically activated in particular phenotypes. We integrated these modules, protein-protein interaction data, Gene Ontology annotations, and our database of gene-phenotype associations derived from literature to predict novel human gene-phenotype associations. Our systematic predictions provide us with the opportunity to perform a global analysis of human gene pleiotropy and its underlying regulatory mechanisms. RESULTS: We applied this method to 338 microarray datasets, covering 178 phenotype classes, and identified 193,145 phenotype-specific coexpression modules. We trained random forest classifiers for each phenotype and predicted a total of 6,558 gene-phenotype associations. We showed that 40.9% genes are pleiotropic, highlighting that pleiotropy is more prevalent than previously expected. We collected 77 ChIP-chip datasets studying 69 transcription factors binding over 16,000 targets under various phenotypic conditions. Utilizing this unique data source, we confirmed that dynamic transcriptional regulation is an important force driving the formation of phenotype specific gene modules. CONCLUSION: We created a genome-wide gene to phenotype mapping that has many potential implications, including providing potential new drug targets and uncovering the basis for human disease phenotypes. Our analysis of these phenotype-specific coexpression modules reveals a high prevalence of gene pleiotropy, and suggests that phenotype-specific transcription factor binding may contribute to phenotypic diversity.

abstract = {A crucial prerequisite to the use of the SF-36 Health Survey in multinational studies is the reproduction of the conceptual model underlying its scoring and interpretation. Structural equation modeling (SEM) was used to test these aspects of the construct validity of the SF-36 in ten IQOLA countries: Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, the United Kingdom, and the United States. Data came from general population surveys fielded to gather normative data. Measurement and structural models developed in the United States were cross-validated in random halves of the sample in each country. SEM analyses supported the eight first-order factor model of health that underlies the scoring of SF-36 scales and two second-order factors that are the basis for summary physical and mental health measures. A single third-order factor was also observed in support of the hypothesis that all responses to the SF-36 are generated by a single, underlying construct--health. In addition, a third second-order factors, interpreted as general well-being, was shown to improve the fit of the model. This model (including eight first-order factors, three second-order factors, and one third-order factor) was cross-validated using a holdout sample within the United States and in each of the nine other countries. These results confirm the hypothesized relationships between SF-36 items and scales and justify their scoring in each country using standard algorithms. Results also suggest that SF-36 scales and summary physical and mental health measures will have similar interpretations across countries. The practical implications of a third second-order SF-36 factor (general well-being) warrant further study.},

title = {Pinning down response inhibition in the brain - Conjunction analyses of the Stop-signal task},
abstract = {Successful behavior requires a finely-tuned interplay of initiating and inhibiting motor programs to react effectively to constantly changing environmental demands. One particularly useful paradigm for investigating inhibitory motor control is the Stop-signal task, where already-initiated responses to Go-stimuli are to be inhibited upon the rapid subsequent presentation of a Stop-stimulus (yielding successful and unsuccessful Stop-trials). Despite the extensive use of this paradigm in functional neuroimaging, there is no consensus on which functional comparison to use to characterize response-inhibition-related brain activity. Here, we utilize conjunction analyses of successful and unsuccessful Stop-trials that are each contrasted against a reference condition. This conjunction approach identifies processes common to both Stop-trial types while excluding processes specific to either, thereby capitalizing on the presence of some response-inhibition-related activity in both conditions. Using this approach on fMRI data from human subjects, we identify a network of brain structures that was linked to both types of Stop-trials, including lateral-inferior frontal and medial frontal cortical areas and the caudate nucleus. In addition, comparisons with a reference condition matched for visual stimulation identified additional activity in the right inferior parietal cortex that may play a role in enhancing the processing of the Stop-stimuli. Finally, differences in stopping efficacy across subjects were associated with variations in activity in the left anterior insula. However, this region was also associated with general task accuracy (which furthermore correlated directly with stopping efficacy), suggesting that it might actually reflect a more general mechanism of performance control that supports response inhibition in a relatively nonspecific way.},

abstract = {Intrauterine growth restriction (IUGR) can lead to infants being born small for gestational age (SGA). SGA is associated with increased neonatal morbidity and mortality as well as short stature, cardiovascular disease, insulin resistance, diabetes mellitus type 2, dyslipidemia and end-stage renal disease in adulthood. In addition, SGA children have decreased levels of intelligence and cognition, although the effects are mostly subtle. The overall outcome of each child is the result of a complex interaction between intrauterine and extrauterine factors. Animal and human studies show structural alterations in the brains of individuals with IUGR/SGA. The presence of growth hormone (GH) receptors in the brain implies that the brain is also a target for GH. Exogenous GH theoretically has the ability to act on the brain. This is exemplified by the effects of GH on cognition in GH-deficient adults. In SGA children, data on the effect of exogenous GH on intelligence and cognition are scant and contradictory.},

title = {Multilevel structural equation modeling},
abstract = {In conventional structural equation models, all latent variables and indicators vary between units (typically subjects) and are assumed to be independent across units. The latter assumption is violated in multilevel settings where units are nested in clusters, leading to within-cluster de- pendence. Different approaches to extending structural equation models for such multilevel settings are examined. The most common approach is to formulate separate within-cluster and between-cluster models. An advantage of this set-up is that it allows software for conventional struc- tural equation models to be `tricked' into estimating the model. However, the standard implementation of this approach does not permit cross-level paths from latent or observed variables at a higher level to latent or ob- served variables at a lower level, and does not allow for indicators varying at higher levels. A multilevel regression (or path) model formulation is therefore suggested in which some of the response variables and some of the explanatory variables at the different levels are latent and measured by multiple indicators. The Generalized Linear Latent and Mixed Model- ing (GLLAMM) framework allows such models to be specified by simply letting the usual model for the structural part of a structural equation model include latent and observed variables varying at different levels.
Models of this kind are applied to the U.S. sample of the Program for International Student Assessment (PISA) 2000 to investigate the relation- ship between the school-level latent variable `teacher excellence' and the student-level latent variable `reading ability', each measured by multiple ordinal indicators.},

abstract = {Psychiatric diagnosis and classification reflect the social and political context of an era and are embedded in it. In the last few decades, culture-bound syndromes reported in non-Western societies constituted the major focus of contention over the validity and universality of psychiatric diagnosis. In contemporary times, social, economic, and political factors, such as the hegemony of the DSM discourse, the managed care culture, pharmaceutical forces, and the global burden of disease study, have virtually made culture-bound syndromes 'disappear'. Once widely believed to be rare outside of the developed West, depression has rapidly become the master narrative of mental health worldwide. In the context of global mental health, the field of psychiatric classification must go beyond routine debates over categories. In order to address the growing discrepancy between needs and services, international cultural psychiatry must engage key social forces, such as psychiatric epidemiology, primary care psychiatry, integration of diagnostic systems, stigma, and advocacy.},

The authors test the original 22-item version and a shortened 20- item version. Model fit is evaluated with confirmatory factor analysis starting with data collected from a sample of hospital nurses (n = 2515) and a sample of nurses and assistants working in residential welfare institutions (n = 1639). Only the fit of the 20-item MBI-HSS was good in both samples. Next the hypothesis of measurement invariance of the 20-item MBI-HSS across the samples is examined, but this hypothesis does not hold. Partial invariance at the level of the sub- scales also could not be confirmed. The authors conclude that for hospital nurses the MBI-HSS factors mean something other than what they mean for professionals working in welfare institu- tions, and suggest that future research could focus upon this difference.},

abstract = {An omnibus permutation test of the overall null hypothesis can be used to assess the association of an entire ensemble of genetic markers with disease in case-control studies. In this approach, p-values for univariate marker-specific Armitage trend tests are combined to form a scalar statistic, which is then used in a permutation test to determine an overall p-value. Two previously described competing methods utilize either a standard two-sample Hotelling's T2 statistic or a global U statistic that is a weighted sum of univariate U statistics. In contrast to Hotelling's test, omnibus tests are much less sensitive to missing data, and utilize all available data. In contrast to the global U test, omnibus tests do not require that the direction of the effects of the individual markers on the risk of disease be correctly specified in advance; in fact, any combination of one- and two-sided univariate tests can be used. Simulations show that, even under circumstances favoring the competing tests (no missing data; direction of effects known), omnibus permutation tests based on Fisher's combining function or the Anderson-Darling statistic typically have power comparable to or greater than Hotelling's and the global U tests.},

title = {Simple group fMRI modeling and inference},
abstract = {While many advanced mixed-effects models have been proposed and are used in fMRI, the simplest, ordinary least squares (OLS), is still the one that is most widely used. A survey of 90 papers found that 92% of group fMRI analyses used OLS. Despite the widespread use, this simple approach has never been thoroughly justified and evaluated; for example, the typical reference for the method is a conference abstract, (Holmes, A., Friston, K., 1998. Generalisability, random effects {\&} population inference. NeuroImage 7 (4 (2/3)), S754, proceedings of Fourth International Conference on Functional Mapping of the Human Brain, June 7-12, 1998, Montreal, Canada.), which has been referenced over 400 times. In this work we fully derive the simplified method in a general setting and carefully identify the homogeneity assumptions it is based on. We examine the specificity (Type I error rate) of the OLS method under heterogeneity in the one-sample case and find that the OLS method is valid, with only slight conservativeness. Surprisingly, a Satterthwaite approximation for effective degrees of freedom only makes the method more conservative, instead of more accurate. While other authors have highlighted the inferior power of the OLS method relative to optimal mixed-effects methods under heterogeneity, we revisit these results and find the power differences very modest. While statistical methods that make the best use of the data are always to be preferred, software or other practical concerns may require the use of the simple OLS group modeling. In such cases, we find that group mean inferences will be valid under the null hypothesis and will have nearly optimal sensitivity under the alternative.},

STUDY DESIGN: This national study included all very low birth weight infants (VLBWIs; birth weight <or= 1500 g or gestational age < 32 weeks) born in Finland between 2000 and 2003 (n = 1169; live-born, n = 900) and full-term controls (n = 368). Register data and parental questionnaires were used. The relationships among HRQoL and QALYs at age 5 years and preterm birth, time of birth, and the level and district of the birth hospital were studied. RESULTS: HRQoL at age 5 years was lower and 1.3 QALYs were lost in VLBWIs compared with controls. Regional differences in the QALYs of VLBWIs were found among the 5 university hospital districts. Birth hospital level or birth outside office hours had no effect on the QALYs of live-born VLBWIs. The adjusted HRQoL total score was not affected by birth outside office hours or by the birth hospital level or district. CONCLUSIONS: Differences in QALYs related to hospital district suggest variation in the care of VLBWIs that needs to be addressed.},

abstract = {Background. The success of large scale surveys depends on well designed questionnaires and the skills of lay interviewers. Discrepancies in prevalence rates between epidemiological surveys and poor agreement between survey interviewer and clinician diagnostic interviews are giving rise to increasing concern among researchers, public health planners and policy developers. New approaches to information collection are called for. The feasibility of training experienced survey interviewers in semi-structured, clinical, diagnostic interviewing has never been investigated systematically across the range of neurotic and psychotic disorders. Methods. Eight experienced survey interviewers from the Office for National Statistics (ONS) were selected and underwent extended training in a Survey Form of SCAN (SCAN-SF). Sixty-four adults, including a majority of psychiatric in-patients were assessed by ONS interviewers and reinterviewed within a week by SCAN-trained clinicians. Feedback was sought from interviewers and trainers. Results. Trainers found lay interviewers coped at least as well with psychotic as with neurotic symptoms. Concordance for any disorder was 0.74 (95% CI: 0.57 to 0.91); for any specific psychotic disorder 0.63 (0.40 to 0.86); for any specific neurotic disorder 0.63 (0.43 to 0.83). Sensitivity ranged from 0.6 to 0.9 and specificity from 0.8 to 0.9. There was no evidence of rater bias. Conclusions. These preliminary findings are very promising. However, before the SCAN-SF, administered by carefully trained lay interviewers, can be recommended in large scale surveys, further evaluations of its feasibility and reliability in the general population are needed.},

Choosing sets of variables is an important method to increase the power of the statistical conclusions and to facilitate the biological interpretation. For the construction of sets, each single variable is considered as the centre of potential sets of variables. Testing for significance is carried out by means of the Westfall-Young principle based on resampling or by the parametric method of spherical tests. The particular requirements for statistical stability are taken into account; each kind of overfitting is avoided. Thus, high power is attained and the familywise type I error can be kept in spite of the large dimension. To obtain graphical representations by heat maps and curves, a specific data compression technique is applied. Gene expression data from B-cell lymphoma patients serve for the demonstration of the procedures.},

title = {Machine learning approaches for phenotype-genotype mapping: predicting heterozygous mutations in the CYP21B gene from steroid profiles},
abstract = {OBJECTIVE: Non-linear relations between multiple biochemical parameters are the basis for the diagnosis of many diseases. Traditional linear analytical methods are not reliable predictors. Novel nonlinear techniques are increasingly used to improve the diagnostic accuracy of automated data interpretation. This has been exemplified in particular for the classification and diagnostic prediction of cancers based on expression profiling data. Our objective was to predict the genotype from complex biochemical data by comparing the performance of experienced clinicians to traditional linear analysis, and to novel non-linear analytical methods. DESIGN AND METHODS: As a model, we used a well-defined set of interconnected data consisting of unstimulated serum levels of steroid intermediates assessed in 54 subjects heterozygous for a mutation of the 21-hydroxylase gene (CYP21B) and in 43 healthy controls. RESULTS: The genetic alteration was predicted from the pattern of steroid levels with an accuracy of 39% by clinicians and of 64% by linear analysis. In contrast, non-linear analysis, such as self-organizing artificial neural networks, support vector machines, and nearest neighbour classifiers, allowed for higher accuracy up to 83%. CONCLUSIONS: The successful application of these non-linear adaptive methods to capture specific biochemical problems may have generalized implications for biochemical testing in many areas. Nonlinear analytical techniques such as neural networks, support vector machines, and nearest neighbour classifiers may serve as an important adjunct to the decision process of a human investigator not 'trained' in a specific complex clinical or laboratory setting and may aid them to classify the problem more directly.},

title = {Combining longitudinal discriminant analysis and partial area under the ROC curve to predict non-response to treatment for hepatitis C virus},
abstract = {A longitudinal discriminant analysis is applied to build predictive models based on repeated measurements of serum hepatitis C virus RNA. These models are evaluated through the partial area under the receiver operating curve index (PA index) and, the final selection of the best model is based on cross-validated estimates of the PA index. Models are compared by building 95% bootstrap confidence interval for the difference in PA index between two models. Data from a randomised trial, in which chronic HCV patients were enrolled, are used to illustrate the application of the proposed method to predict treatment outcome.},
