OBJECTIVES: The study aims to develop a short form of the compulsive internet use scale (CIUS), which can be used in multitopic and general population health surveys and is invariant across different sexes, linguistic regions, and ages. METHODS: Two general population surveys from 2013 and 2015 were used as learning (n = 1,371) and validation samples (n = 1,550), respectively. Reducing items from the original CIUS was based on the following: (a) correlated errors between items, (b) differential item functioning, and (c) measurement invariance...

Most mental disorders have their first onset in early adulthood. Epidemiological research, as well as research on preventive and early interventions, is therefore very important. This thematic issue focuses on one of the first systematic attempts to develop such services for college students. The WHO World Mental Health International College Student (WMH-ICS) initiative is based on the largest and continuously growing epidemiological dataset ever collected in college students. Based on these results, the initiative has now started to implement internet-based interventions for common mental disorders and emotional problems...

OBJECTIVES: Real world implementation of proactive screening and brief intervention in health care is threatened by high cost. Using e-health interventions and screening for multiple health risk factors may provide more efficiency. We describe methodological details of a proactive multipurpose health risk screening in health care settings and report on participation rates, participants' characteristics, and participation factors. METHODS: Patients between 18 and 64 years from ambulatory practices and hospitals were proactively approached by study assistants at three sites for a computerized screening on harmful alcohol and tobacco consumption, depressive symptoms, insufficient fruit/vegetable consumption, physical inactivity and overweight...

OBJECTIVES: Mental health disorders are highly prevalent among university students. Universities could be an optimal setting to provide evidence-based care through the Internet. As part of the World Mental Health International College Student initiative, this systematic review and meta-analysis synthesizes data on the efficacy of Internet-based interventions for university students' mental health. METHOD: A systematic literature search of bibliographical databases (CENTRAL, MEDLINE, and PsycINFO) for randomized trials examining psychological interventions for the mental health (depression, anxiety, stress, sleep problems, and eating disorder symptoms), well-being, and functioning of university students was performed through April 30, 2018...

OBJECTIVES: Interoception is a general sensitivity to bodily sensations that informs motivational processes and behaviours. Interoceptive abilities seem to be impaired in several clinical conditions, and the development of new pragmatic instruments to assess subjective components of interoception are crucially needed. An easy to use paper and pencil questionnaire measuring sensitivity to bodily sensations was validated in an Italian sample (Self-Awareness Questionnaire; SAQ). METHODS: In the present study, we created and evaluated an electronic version of the SAQ in Italian and English language...

BACKGROUND: The majority of university students with mental health problems are untreated. Only a small empirical literature exists on strategies to increase mental health service use. AIMS: To investigate the effects and moderators of a brief acceptance-facilitating intervention on intention to use mental health services among university students. METHOD: Within the German site of the World Health Organization's World Mental Health International College Student (WMH-ICS) initiative, 1,374 university students were randomized to an intervention condition (IC; n = 664) or a control condition (CC; n = 710) that was implemented in the survey itself...

OBJECTIVES: Comorbidity is a common feature of mental disorders. However, needs assessment surveys focus largely on individual disorders rather than on comorbidity even though the latter is more important for predicting suicidal thoughts and behaviors. In the current report, we take a step beyond this conventional approach by presenting data on the prevalence and correlates (sociodemographic factors, college-related factors, and suicidal thoughts and behaviors) of the main multivariate profiles of common comorbid Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV disorders among students participating in the first phase of the World Health Organization World Mental Health International College Student initiative...

OBJECTIVES: No consensus has been reached regarding the theoretical dimensions underlying the Scale for Suicide Ideation (SSI) and Beck's Scale for Suicide Ideation (BSI), widely used in research and clinical practice. This undermines the understanding and management of suicidal behavior. METHODS: The factor structure of the SSI and the BSI was investigated in 201 patients visiting the emergency department of the Geneva University Hospital, Switzerland, for suicidal ideation or a suicide attempt...

OBJECTIVES: There is a need for brief and publicly-available assessments of attention deficit hyperactivity disorder (ADHD) easily administered in large-scale survey efforts monitoring symptoms among adolescents. The ADHD Self-Report Scale v1.1 (ASRS; Kessler et al., 2005) Screener, a six-item measure of ADHD symptoms, is a valid and reliable screening instrument for ADHD among adults. The current study provides initial evidence for the reliability and validity of the ASRS Screener among a community sample of U...

OBJECTIVES: Most of the addiction studies focus on very specific aspects of addictions, often with contradictory results, and integrated studies are quite rare. Experimental studies comparing underlying mechanisms of addictions and analyzing data from an integrative psychological and genetic perspective are almost nonexistent. The aim of the present paper is to describe the research protocol of the Psychological and Genetic Factors of Addictive Behaviors (PGA) study, which applies an integrative approach to understanding the acquisition, development, and maintenance of addictive behaviors...

OBJECTIVE: To facilitate future outcome studies, we aimed to develop a robust and replicable method for estimating a categorical and dimensional measure of Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) attention deficit hyperactivity disorder (ADHD) in the 1970 British Cohort Study (BCS70). METHOD: Following a data mining framework, we mapped DSM-5 ADHD symptoms to age 10 BCS70 data (N = 11,426) and derived a 16-item scale (α = 0.85). Mapping was validated by an expert panel...

OBJECTIVES: Recommended cut-off criteria for testing measurement invariance (MI) using the comparative fit index (CFI) vary between -0.002 and -0.01. We compared CFI results with those obtained using Bayesian approximate MI for cognitive function. METHODS: We used cognitive function data from Waves 1-5 of the English Longitudinal Study of Ageing (ELSA; Wave 1 n = 11,951), a nationally representative sample of English adults aged ≥50. We tested for longitudinal invariance using CFI and approximate MI (prior for a difference between intercepts/loadings ~N(0,0...

OBJECTIVES: Internet gambling is often considered as a risk factor for gambling problems compared with land-based gambling. In parallel, this online activity generates data that can be useful to characterize Internet gambling behaviours. The objectives were to define a typology of online lotteries and scratch games gamblers' behaviours in order to identify early risky gambling behaviours and to classify gamblers in order to identify individuals with global risky gambling behaviours. METHODS: We performed a multilevel latent class cluster based on player account-based data of 10,000 gamblers from a French online operator...

The circumplex model for core affect is among the most prominent characterizations of emotion and has received extensive empirical support. However, no prior study exists that connects the measurement of depression and anxiety with the core affect structure and the bipolar dimensions of arousal and valence it includes. OBJECTIVES: This study aims to investigate the reconcilability between a continuous model based on Russell's core affect system and a discrete entity view on depression and anxiety...
