In their study, Stavropoulos et al. (2023) capitalized on supervised machine learning and a longitudinal design and reported that the User-Avatar Bond could be accurately employed to detect Gaming Disorder (GD) risk in a community sample of gamers. The authors suggested that the User-Avatar Bond is a "digital phenotype" that could be used as a diagnostic indicator for GD risk.

Sexual desire is a complex construct with important implications for sexual functioning and well-being. In this research, we translated the Sexual Desire Inventory (SDI-2), a widely used scale for assessing sexual (desire), into 25 languages from English and used data from the International Sex Survey (ISS) to (a) investigate its psychometric properties (i.e.

Impulsivity is a multidimensional construct linked to a broad spectrum of psychopathological and neuropsychological disorders. The UPPS-P model has emerged as a valuable tool for assessing impulsivity from a multi-dimensional perspective. Despite its relevance, few studies have examined the psychometric properties of the UPPS-P scale scores in a large, representative sample of adolescents.

Department of Behavioural and Cognitive Sciences, Institute for Health and Behaviour, University of Luxembourg, Esch-sur-Alzette, Luxembourg.

Enactive cognition emphasizes co-constructive roles of humans and their environment in shaping cognitive processes. It is specifically engaged in the mental simulation of behaviors, enhancing the connection between perception and action. Here we investigated the core network of brain regions involved in enactive cognition as applied to mental simulations of physical exercise.

Background And Objectives: As the gaming industry experiences exponential growth, concerns about gaming disorder (GD) also grow. It is crucial to understand the structural features of games that can interact with individual characteristics of gamers to promote GD. This research consolidates the views of an international body of panelists to create an assessment tool for gauging the addictive potential of distinct games.

Background: The three-item Sexual Distress Scale (SDS-3) has been frequently used to assess distress related to sexuality in public health surveys and research on sexual wellbeing. However, its psychometric properties and measurement invariance across cultural, gender and sexual subgroups have not yet been examined. This multinational study aimed to validate the SDS-3 and test its psychometric properties, including measurement invariance across language, country, gender identity, and sexual orientation groups.

With the advent of digital technologies, online sports betting is spurring a fast-growing expansion. In this study, we examined how sports betting availability modulates the brain connectivity of frequent sports bettors with [problem bettors (PB)] or without [non-problem bettors (NPB)] problematic sports betting. We conducted functional connectivity analyses centred on the ventral anterior insular cortex (vAI), a brain region playing a key role in the dynamic interplay between reward-based processes.

Background: Depression and anxiety are among the most prevalent mental health issues experienced worldwide. However, whereas cross-cultural studies utilize psychometrically valid and reliable scales, fewer can meaningfully compare these conditions across different groups. To address this gap, the current study aimed to psychometrically assess the Brief Symptomatology Index (BSI) in 42 countries.

Behavior frequency measures in behavioral addictions research fail to account for how engagement in the activity relates to each respondent's personal circumstances. We propose a "Red Box, Green Box" method, an alternative to conventional self-report behavior questions. Participants report two distinct time-based values: (1) Green box: time spent engaged in the activity during 'free' time, and (2) Red box: engagement in the activity at times when the respondent should be doing something else (e.

Background: Attention-deficit hyperactivity disorder (ADHD) is characterized by difficulty paying attention, poor impulse control, and hyperactive behavior. It is associated with several adverse health and social outcomes and leads to an increased risk of criminality and recidivism. Worldwide, ADHD is thus highly prevalent in prisons.

Gaming disorder (GD) screening often involves self-report survey measures to detect the presence of symptoms. Studies have shown that gamers' responses vary greatly across survey items. Some symptoms, such as preoccupation and tolerance, are frequently reported by highly engaged but non-problematic gamers, and therefore these symptoms are thought to lack specificity and are suggested to be less important in classification decisions.

Validation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and Its Association with Functional Impairment in Brazilian Gamers.

Trends Psychiatry Psychother

October 2023

Graduate Program in Psychiatry and Behavioral Sciences, Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil. Psychodynamic Psychiatry Research Laboratory, Hospital de Clínicas de Porto Alegre, Porto Alegre, Brazil.

Introduction: Despite the growing recognition of gaming disorder as a mental disorder, there is still debate about how it should be best screened for. This is especially relevant in countries where prevalence studies that could support evidence-based policymaking are still to be conducted. This study aims to evaluate the psychometric properties of the Brazilian Portuguese version of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and to explore its association with functional impairment.

Introduction: Despite being a widely used screening questionnaire, there is no consensus on the most appropriate measurement model for the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, there have been limited studies on its measurement invariance across cross-cultural subgroups, genders, and sexual orientations.

Aims: The present study aimed to examine the fit of different measurement models for the AUDIT and its measurement invariance across a wide range of subgroups by country, language, gender, and sexual orientation.

Problematic online behaviors and psychopathology in Australia.

Psychiatry Res

September 2023

School of Medicine and Psychology, Australian National University, Canberra, ACT, Australia; Graduate School of Health, University of Technology Sydney, NSW, Australia.

This study aimed to ascertain frequency rates and predictors of six problematic online behaviors (POBs) in an Australian sample. Participants (N = 1626) completed instruments measuring problematic online gaming, cyberchondria, problematic cybersex, problematic online shopping, problematic use of social networking sites, problematic online gambling, anxiety, depression and attention deficit/hyperactivity disorder (ADHD). Each POB was presumed to be present based on the cut-off score on the corresponding instrument and at least one indicator of interference with functioning.

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is an instrument to screen substance-use-related health risks. However, little is known whether the ASSIST could be further shortened while remaining psychometrically sound across different countries, languages, gender identities, and sexual-orientation-based groups. The study aimed to validate a shortened 11-item ASSIST (ASSIST-11).

Prevalence of problematic Internet use and problematic gaming in Spanish adolescents.

Psychiatry Res

Institute of Psychology, University of Lausanne, Lausanne, Switzerland; Centre for Excessive Gambling, Addiction Medicine, Lausanne University Hospitals (CHUV), Lausanne, Switzerland. Electronic address:

Article Synopsis
  • This study assessed the prevalence of problematic Internet use (33%) and problematic gaming (3.1%) among a large sample of 41,507 Spanish adolescents, using valid measurement scales.
  • It identified factors influencing risky behaviors, noting that females with higher parental education and increased online time were at risk for Internet problems, while males from unstable living environments were more likely to exhibit problematic gaming.
  • The study suggests that the ICD-11 framework offers more accurate prevalence rates compared to the DSM-5, which may overstate the pathologization of these behaviors.
