OBJECTIVES: Social anxiety disorder (SAD) is a serious and prevalent psychiatric condition, with a heritable component. However, little is known about the characteristics that are associated with the genetic component of SAD, the so-called "endophenotypes". These endophenotypes could advance our insight in the genetic susceptibility to SAD, as they are on the pathway from genotype to phenotype. The Leiden Family Lab study on Social Anxiety Disorder (LFLSAD) is the first multiplex, multigenerational study aimed to identify neurocognitive endophenotypes of social anxiety...

OBJECTIVES: The study aims to generate an immunological age (IA) trait on the basis of immune cell differentiation parameters, and to test whether the IA is related to age and disease characteristics. METHODS: Forty-four euthymic type I bipolar disorder patients were included in this study. Five immunosenescence-related parameters were assessed: proportions of late-differentiated cells (e.g., CD3+CD8+CD28-CD27- and CD3-CD19+IgD-CD27-), and the expression of CD69, CD71, and CD152 after stimulation...

OBJECTIVES: Carver and White's behavioral inhibition system and behavioral activation system (BIS/BAS) scales are the most widely used to assess constructs of the revised reinforcement sensitivity theory. This study provides a re-examination of the latent structure of the original BIS/BAS scales. METHODS: The interpretability of the three purported BAS subfactors relative to a "general behavioral activation" factor was assessed using Schmid-Leiman and standard confirmatory factor analysis...

Se-Kang Kim, Rachel A Annunziato
OBJECTIVES: We employed the correspondence analysis (CA) biplot to estimate correlations between gender-age levels of cardiovascular disease patients and their psychiatric and physical symptoms. Utilization of this correlation estimation can inform clinical practice by elucidating associations between certain psychiatric or physical symptoms and specific gender-age levels. METHOD: The CA biplot utilized here was designed to visually inspect row-column category associations in a 2-dimensional plane and then to numerically estimate the category associations with correlations...

OBJECTIVES: Genome-wide association studies (GWAS) have become increasingly popular to identify associations between single nucleotide polymorphisms (SNPs) and phenotypic traits. The GWAS method is commonly applied within the social sciences. However, statistical analyses will need to be carefully conducted and the use of dedicated genetics software will be required. This tutorial aims to provide a guideline for conducting genetic analyses. METHODS: We discuss and explain key concepts and illustrate how to conduct GWAS using example scripts provided through GitHub (https://github...

Subtyping depression is important in order to further delineate biological causes of depressive syndromes. The aim of this study was to evaluate clinical and outcome characteristics of distinct subtypes of depression and to assess proportion and features of patients fulfilling criteria for more than one subtype. Melancholic, atypical and anxious subtypes of depression were assessed in a naturalistic sample of 833 inpatients using DSM-IV specifiers based on operationalized criteria. Baseline characteristics and outcome criteria at discharge were compared between distinct subtypes and their overlap...

OBJECTIVES: There is an increasing debate about the impact of mental health screening. We illustrate the use of a decision making framework that can be applied when there is no sufficient data to support a traditional cost-benefit analysis. METHODS: We conducted secondary analyses of data from 459 male prisoners who were screened upon intake. We compared the potential benefit of different approaches (screening, history taking, and universal interventions) to allocating treatment resources using decision curve analysis...

OBJECTIVES: As electronic mental health records become more widely available, several approaches have been suggested to automatically extract information from free-text narrative aiming to support epidemiological research and clinical decision-making. In this paper, we explore extraction of explicit mentions of symptom severity from initial psychiatric evaluation records. We use the data provided by the 2016 CEGS N-GRID NLP shared task Track 2, which contains 541 records manually annotated for symptom severity according to the Research Domain Criteria...

The nonverbal behavior (NVB) of people diagnosed with schizophrenia consistently interacts with their symptoms during the assessment. Previous studies frequently observed such an interaction when a prevalence of negative symptoms occurred. Nonetheless, a list of NVBs linked to negative symptoms needs to be defined. Furthermore, a list of items that can exhaustively assess such NVBs is still needed. The present study aims to introduce both lists by using the Formal Psychological Assessment. A deep analysis was performed on both the scientific literature and the DSM-5 for constructing the set of nonverbal behaviors; similarly, an initial list of 138 items investigating the behaviors was obtained from instruments used to assess schizophrenia...

Age-specific incidence estimates are important and useful facts in psychiatric epidemiology, but incidence estimation can be challenging. Methods artifacts are possible. In the United States, where the minimum legal drinking age is 21 years, recent cross-sectional field research on 12- to 25-year-olds applied conventional "age-at-assessment" approaches (AAA) for incidence estimation based on 12-month recall. Estimates disclosed unexpected nonlinear patterns in age-specific incidence estimates for both drinking onset and for transitioning from first drink to heavy drinking...

This study examined whether the Structured Clinical Interview for DSM (SCID), a widely used semistructured interview designed to assess psychopathology categorically, can be adapted to identify reliable and valid severity dimensions of psychopathology. The present study also examined whether these severity dimensions have better psychometric properties (internal consistency, test-retest reliability, and concurrent and predictive validity) than categorical diagnoses. Participants (N = 234) were recruited from the community and clinics...

Analyzing count data is frequent in addiction studies but may be cumbersome, time-consuming, and cause misleading inference if models are not correctly specified. We compared different statistical models in a simulation study to provide simple, yet valid, recommendations when analyzing count data.We used 2 simulation studies to test the performance of 7 statistical models (classical or quasi-Poisson regression, classical or zero-inflated negative binomial regression, classical or heteroskedasticity-consistent linear regression, and Mann-Whitney test) for predicting the differences between population means for 9 different population distributions (Poisson, negative binomial, zero- and one-inflated Poisson and negative binomial, uniform, left-skewed, and bimodal)...

Assessments of child psychopathology are often derived from parental and teacher reports, yet there is substantial disagreement. This study utilized data from 7 European countries to examine parent-teacher agreement and possible explanatory factors for parent-teacher disagreement such as child and family characteristics, parenting dimensions, and maternal distress were explored. Parent-teacher agreement of the Strengths and Difficulties Questionnaire were assessed using a cross-sectional survey of 4,894 school aged children 6-11 from the School Children Mental Health Europe Project...

In preparation for ICD-11, the adjustment disorder (AjD) diagnosis has undergone considerable revisions; however, the latent structure of AjD remains uncertain. It is unclear whether AjD is best represented as a unidimensional or multidimensional construct. This study performed a comprehensive assessment of the latent structure of AjD symptomatology and assessed its concurrent and discriminant validity. Individuals who experienced involuntary job loss (N = 333) completed a self-report measure of AjD symptoms...
