The short version of the Sexual Distress Scale (SDS-3): Measurement invariance across countries, gender identities, and sexual orientations.

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. Methods: We used global survey data from 82,243 individuals (Mean age=32.39 years; 40.3 % men, 57.0 % women, 2.8 % non-binary, and 0.6 % other genders) participating in the International Sexual Survey (ISS; https://internationalsexsurvey.org/) across 42 countries and 26 languages. Participants completed the SDS-3, as well as questions regarding sociodemographic characteristics, including gender identity and sexual orientation. Results: Confirmatory factor analysis (CFA) supported a unidimensional factor structure for the SDS-3, and multi-group CFA (MGCFA) suggested that this factor structure was invariant across countries, languages, gender identities, and sexual orientations. Cronbach's α for the unidimensional score was 0.83 (range between 0.76 and 0.89), and McDonald's ω was 0.84 (range between 0.76 and 0.90). Participants who did not experience sexual problems had significantly lower SDS-3 total scores (M = 2.99; SD=2.54) compared to those who reported sexual problems (M = 5.60; SD=3.00), with a large effect size (Cohen's d = 1.01 [95 % CI=-1.03, -0.98]; p < 0.001). Conclusion: The SDS-3 has a unidimensional factor structure and appears to be valid and reliable for measuring sexual distress among individuals from different countries, gender identities, and sexual orientations.

Web-Based Emotion Regulation Training for Sexual Health: Randomized Controlled Trial.

BACKGROUND: Effective emotional regulation (ER) skills are important for sexual function, as they impact emotional awareness and expression during sexual activity, and therefore, satisfaction and distress. Emotion regulation interventions may offer a promising approach to improve sexual health. Web-based emotion regulation may be a therapeutic strategy for men and women with sexual health concerns. Nevertheless, there is a scarcity of intervention trials investigating its effects in this context, much less using the internet. OBJECTIVE: This study aims to investigate the effects of a web-based emotion regulation training program for sexual function in both men and women. METHODS: The participants were recruited based on their self-reported sexual problems, which for men was defined by a score of <25 on the International Index Erectile Function (IIEF) and for women by a score of <26.55 on the Female Sexual Function Index (FSFI). The final sample included 60 participants who were randomized to either a web-based emotion regulation training for sexual function or to a waitlist control group. The treatment consisted of an 8-week web-based emotion regulation training for sexual function. The participants were assessed at baseline, post intervention, and the 3-month follow-up. RESULTS: Of the 60 participants included, only 6 completed all 3 assessment points (n=5, 20% in the treatment group and n=1, 5% in the waitlist control group) after receiving the intervention. At follow-up, there were no significant differences between groups in any measure. Among the intervention completers, large-to-moderate within-group effect sizes were observed between the assessment points on measures of emotion regulation, depression, lubrication, orgasm, thoughts of sexual failure, and abuse during sexual activity. The adherence rate was very low, limiting the generalizability of the findings. CONCLUSIONS: Participants who completed the intervention showed improvements in both sexual function domains and emotion regulation. Nonetheless, due to a high dropout rate, this trial failed to collect sufficient data to allow for any conclusions to be drawn on treatment effects.

Increased ventral anterior insular connectivity to sports betting availability indexes problem gambling.

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. We re-analysed a dataset on sports betting availability undertaken in PB (n = 30) and NPB (n = 35). Across all participants, we observed that sports betting availability elicited positive vAI coupling with extended clusters of brain activation (encompassing the putamen, cerebellum, occipital, temporal, precentral and central operculum regions) and negative vAI coupling with the orbitofrontal cortex. Between-group analyses showed increased positive vAI coupling in the PB group, as compared with the NPB group, in the left lateral occipital cortex, extending to the left inferior frontal gyrus, the anterior cingulate gyrus and the right frontal pole. Taken together, these results are in line with the central assumptions of triadic models of addictions, which posit that the insular cortex plays a pivotal role in promoting the drive and motivation to get a reward by 'hijacking' goal-oriented processes toward addiction-related cues. Taken together, these findings showed that vAI functional connectivity is sensitive not only to gambling availability but also to the status of problematic sport betting.

Protocol of a monocentric, double-blind, randomized, superiority, controlled trial evaluating the effect of in-prison OROS-methylphenidate vs. placebo treatment in detained people with attention-deficit hyperactivity disorder (BATIR).

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. However, ADHD treatment has been neglected in such environments. Stimulant medications such as osmotic-release oral system methylphenidate (OROS-MPH) are first-line treatments in the general population, but they are under-prescribed in prisons due to concerns about abuse, even though such claims are not empirically supported. This project aims to compare the efficacy of a 3-month in-prison OROS-MPH vs. placebo treatment on the severity of core ADHD symptoms and relevant in- and post-prison outcomes. METHODS: This study is a phase III, double-blinded, randomized, superiority, controlled trial of OROS-MPH vs. placebo. After randomization, the participants will receive 3 months of treatment with OROS-MPH or placebo (1:1 ratio) while incarcerated. Upon release, all participants will be offered the treatment (OROS-MPH) for 1 year but will remain blinded to their initial study group. The study will be conducted at the Division of Prison Health, Geneva, Switzerland, among incarcerated men (n = 150). Measures will include (1) investigator-rated ADHD symptoms, (2) acute events collected by the medical and prison teams, (3) assessment of the risk of recidivism, (4) medication side effects, (5) medication adherence, (6) study retention, (7) health care/prison costs, and (8) 1-year recidivism. Analyses will include bivariable and multivariable modeling (e.g., regression models, mixed-effects models, survival analyses) and an economic evaluation (cost-benefit analysis). DISCUSSION: We expect that early identification and treatment of ADHD in prison will be an important public health opportunity and a cost-effective approach that is likely to reduce the vulnerability of incarcerated individuals and promote pathways out of criminal involvement. The study will also promote standards of care for people with ADHD in prison and provide recommendations for continuity of care after release. TRIAL REGISTRATION: ClinicalTrials.gov NCT05842330 .

Functional and dysfunctional impulsivity mediates the relationships between 'Dark Triad' traits and cyberbullying perpetration.

BACKGROUND: Cyberbullying perpetration and victimisation have been associated with psychological distress, including depression and suicidal ideation. Prior studies have shown that the 'Dark Triad' personality traits (narcissism, Machiavellianism, and psychopathy) are associated with greater likelihood of perpetration, yet there is a research gap regarding potential mediators of this relationship. AIMS: To test whether functional and dysfunctional impulsivity act as mediators between Dark Triad traits and cyberbullying perpetration. METHODS: A cross-sectional online study was conducted, in which a sample of 141 university students (63% male) from Malaysia were recruited by online and local poster advertising inviting them to complete a questionnaire containing a series of psychometric scales, including measures of 'Dark Triad' personality traits, impulsivity and cyberbullying perpetration. RESULTS: A relationship between cyberbullying perpetration and higher psychopathy scale scores was mediated by dysfunctional, but not functional, impulsivity. The relationship between cyberbullying and narcissism scores was not mediated by impulsivity. Higher Machiavellianism scores were similarly associated with cyberbullying, but there was no correlation at all between Machiavellianism and impulsivity scores. CONCLUSION: Our findings add to the literature by showing that not only Dark Triad scale scores are associated with cyberbullying, but that difficulty in refraining from or controlling impulsive behaviours (dysfunctional impulsivity) may be a key component in this relationship. Given that our sample was of generally well-functioning people, our findings may not extend to those with serious cyberbullying problems. Yet, they provide avenues for identifying people at risk of such behaviours before problems become well-established and call for more nuanced approaches towards understanding and intervening with problematic cyberbullying.

Red box, green box: A self-report behavioral frequency measurement approach for behavioral addictions research.

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.g., studying, working, sleeping, exercising, etc.). Some practical examples of the 'red box, green box' method are provided. This method may help to calibrate behavioral frequency for each respondent and yield clearer insights into displacement effects and risks associated with frequency of use. We suggest some future research directions to test the feasibility and utility of this approach in different implementations.

Mental health professionals' use of the ICD-11 classification of impulse control disorders and behavioral addictions: An international field study.

Background and aims: The ICD-11 chapter on mental, behavioral and neurodevelopmental disorders contains new controversial diagnoses including compulsive sexual behavior disorder (CSBD), intermittent explosive disorder (IED) and gaming disorder. Using a vignette-based methodology, this field study examined the ability of mental health professionals (MHPs) to apply the new ICD-11 diagnostic requirements for impulse control disorders, which include CSBD and IED, and disorders due to addictive behaviors, which include gaming disorder, compared to the previous ICD-10 guidelines. Methods: Across eleven comparisons, members of the WHO's Global Clinical Practice Network (N = 1,090) evaluated standardized case descriptions that were designed to test key differences between the diagnostic guidelines of ICD-11 and ICD-10. Results: The ICD-11 outperformed the ICD-10 in the accuracy of diagnosing impulse control disorders and behavioral addictions in most comparisons, while the ICD-10 was not superior in any. The superiority of the ICD-11 was particularly clear where new diagnoses had been added to the classification system or major revisions had been made. However, the ICD-11 outperformed the ICD-10 only in a minority of comparisons in which mental health professionals were asked to evaluate cases with non-pathological high involvement in rewarding behaviors. Discussion and Conclusions: Overall, the present study indicates that the ICD-11 diagnostic requirements represent an improvement over the ICD-10 guidelines. However, additional efforts, such as training programs for MHPs and possible refinements of diagnostic guidance, are needed to avoid over-diagnosis of people who are highly engaged in a repetitive and rewarding behavior but below the threshold for a disorder.

Cross-Cultural Adult ADHD Assessment in 42 Countries Using the Adult ADHD Self-Report Scale Screener.

OBJECTIVE: We analyzed adult ADHD symptoms in a cross-cultural context, including investigating the occurrence and potential correlates of adult ADHD and psychometric examination of the Adult ADHD Self-Report Scale (ASRS) Screener. METHOD: Our analysis is based on a large-scale research project involving 42 countries (International Sex Survey, N=72,627, 57% women, Mage=32.84; SDage=12.57). RESULTS: The ASRS Screener demonstrated good reliability and validity, along with partial invariance across different languages, countries, and genders. The occurrence of being at risk for adult ADHD was relatively high (21.4% for women, 18.1% for men). The highest scores were obtained in the US, Canada, and other English-speaking Western countries, with significantly lower scores among East Asian and non-English-speaking European countries. Moreover, ADHD symptom severity and occurrence were especially high among gender-diverse individuals. Significant associations between adult ADHD symptoms and age, mental and sexual health, and socioeconomic status were observed. CONCLUSIONS: Present results show significant cross-cultural variability in adult ADHD occurrence as well as highlight important factors related to adult ADHD. Moreover, the importance of further research on adult ADHD in previously understudied populations (non-Western countries) and minority groups (gender-diverse individuals) is stressed. Lastly, the present analysis is consistent with previous evidence showing low specificity of adult ADHD screening instruments and contributes to the current discussion on accurate adult ADHD screening and diagnosis.

Cross-cultural validation and measurement invariance of anxiety and depression symptoms: A study of the Brief Symptom Inventory (BSI) in 42 countries.

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. METHODS: Using data from the International Sex Survey (N = 82,243; Mage = 32.39; SDage = 12.52; women: n = 46,874; 57 %), we examined the reliability of depression and anxiety symptom scores of the BSI-18, as well as evaluated evidence of construct, invariance, and criterion-related validity in predicting clinically relevant variables across countries, languages, genders, and sexual orientations. RESULTS: Results corroborated an invariant, two-factor structure across all groups tested, exhibiting excellent reliability estimates for both subscales. The 'caseness' criterion effectively discriminated among those at low and high risk of depression and anxiety, yielding differential effects on the clinical criteria examined. LIMITATIONS: The predictive validation was not made against a clinical diagnosis, and the full BSI-18 scale was not examined (excluding the somatization sub-dimension), limiting the validation scope of the BSI-18. Finally, the study was conducted online, mainly by advertisements through social media, ultimately skewing our sample towards women, younger, and highly educated populations. CONCLUSIONS: The results support that the BSI-12 is a valid and reliable assessment tool for assessing depression and anxiety symptoms across countries, languages, genders, and sexual orientations. Further, its caseness criterion can discriminate well between participants at high and low risk of depression and anxiety.

Physical Exercise to Redynamize Interoception in Substance use Disorders.

Physical exercise is considered a promising medication-free and cost-effective adjunct treatment for substance use disorders (SUD). Nevertheless, evidence regarding the effectiveness of these interventions is currently limited, thereby signaling the need to better understand the mechanisms underlying their impact on SUD, in order to reframe and optimize them. Here we advance that physical exercise could be re-conceptualized as an "interoception booster", namely as a way to help people with SUD to better decode and interpret bodily-related signals associated with transient states of homeostatic imbalances that usually trigger consumption. We first discuss how mismatches between current and desired bodily states influence the formation of reward-seeking states in SUD, in light of the insular cortex brain networks. Next, we detail effort perception during physical exercise and discuss how it can be used as a relevant framework for re-dynamizing interoception in SUD. We conclude by providing perspectives and methodological considerations for applying the proposed approach to mixed-design neurocognitive research on SUD.

The Mediating Effects of Perceived Family Support in the Relationship Between Anxiety and Problematic Smartphone Use: A Cross-Cultural Validation.

ABSTRACT: Problematic smartphone use (PSU) is frequently considered a public health issue, especially in East Asia and Europe. Yet, there is a paucity of research focusing on cultural and familial determinants of PSU. This cross-cultural study aimed to investigate smartphone usage patterns and possible mediating effects of perceived family support (PFS) from a stress-coping perspective. Convenience samples of 790 Chinese and 439 Belgian undergraduates completed an online survey that focused on sociodemographics and psychological variables ( i.e. , anxiety, depression, PFS, and PSU). In both samples, PSU was positively associated with anxiety and depression, and negatively associated with PFS. However, after controlling for sex and age in structural equation models, the consistent mediating effects of PFS were only found between anxiety and PSU in both cultural settings. These findings suggest that psychological interventions that take into account familial factors could be helpful for young people presenting with anxiety and PSU.

Further evidence for the bidimensionality of the components model of addiction: a reply to Amendola (2023).

In our original research article entitled "Deconstructing the components model of addiction: an illustration through "addictive" use of social media" (Fournier et al., 2023), we showed that the Bergen Social Media Addiction Scale, a six-item psychometric instrument derived from the components model of addiction to assess social media "addiction", did not form a unitary, but a bidimensional construct in which some components (i.e., salience, tolerance) were not associated with psychopathological symptoms, thus conflating central and peripheral features of addiction. Subsequently, in a recent commentary, Amendola (2023) sought to determine whether our findings were driven by the use of data aggregated from multiple independent datasets, i.e., a decision we transparently acknowledged as a limitation in our original research article. Following their re-analysis, Amendola (2023) claimed to have demonstrated that a unidimensional model best fitted the data. However, they only reported results for a partial set of models relevant to this investigation. In the present reply, through a transparent assessment and reporting of all unidimensional and bidimensional models relevant to this investigation, we show that the bidimensionality of the Bergen Social Media Addiction Scale is, in fact, tenable, robust, and consistent across multiple independent datasets. In line with the growing evidence demonstrating that many sets of criteria involved in operationalizing behavioral addictions pathologize involvement in appetitive behaviors, these results highlight the necessity to renew the conceptualization and assessment of behavioral addictions.

The Role of Emotion Regulation Strategies for Sexual Function and Mental Health: A Cluster Analytical Approach.

We investigated distinct profiles in emotion regulation strategies (reappraisal and suppression) and their associations with sexual function and mental health. The online survey sample consisted of 5436 adult participants. The gender stratified cluster analysis resulted in a four-cluster solution for both men and women. Better sexual function and mental health scores were found for participants with high cognitive reappraisal and low expressive suppression. High expressive suppression was associated with higher anxiety and depression and worse sexual function. Sexological care should take into account the assessment of emotion regulation abilities and emotion regulation training interventions to support reappraisal strategies.

Sharpen the focus on chemsex.

Chemsex is the intentional use of substances in sexualized settings among men who have sex with men. An increasing public health issue, chemsex has estimated prevalence rates of 3% to 29% in men who have sex with men. Known risks of chemsex include higher exposure to HIV and other STIs, addiction, and cardiovascular problems. Recent research has also shown that chemsexers are prone to depression, anxiety, psychotic experiences, and cognitive impairment. Our commentary highlights the discrepancy between the public health burden associated with risky chemsex practices and the research gap in this domain. We warn against the simplistic application to chemsex of existing theoretical concepts or therapeutic strategies that work for addictions and at-risk sexual behaviours. Such an approach neglects the unique features of this emerging phenomenon, which mainly affects stigmatized minorities.

Reconsidering item response categories in gaming disorder symptoms measurement.

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. We argue that the influence of response categories (e.g., dichotomous responses, such as 'yes' or 'no'; or frequency categories, such as 'rarely' and 'often') on item responses has been relatively underexplored despite potentially contributing significantly to the psychometric performance of items and scales. In short, the type of item response may be just as important to symptom reporting as the content of survey questions. We propose some practical alternatives to currently used item categories across GD tools. Research should examine the performance of different response categories, including whether certain response categories aid respondents' comprehension and insight, and better capture pathological behaviours and harms.

Distortions in time perception related to videogames, pornography, and TV series exposure: An experimental study in three independent samples.

Background and aims: Time perception is a cognitive process involving both the ability to estimate the duration of an event (time estimation, TE) and the subjective perception of its passage (time passage, TP). Studies show that alteration in TE/TP is associated with substance use disorders. However, little is known about the impact of these alterations in potentially problematic online behaviors. We explore TE and TP while participants were exposed to cues related to videogames, pornography, and TV series, and the relationship of TE and TP with scores from instruments that measure problematic gaming (PG), problematic pornography use (PPU), and problematic binge-watching (BW). Methods: Participants from three independent samples (40 men from Luxembourg; 99 Spanish men, 111 Spanish women) completed an experimental task designed to assess TE and TP while they were exposed to short clips related to videogames, pornography, TV series, and documentaries (control condition). Participants also completed different self-reports. Results: Whereas men underestimated the time that they were exposed to pornography and TV series, women overestimated it. For videogames, we showed a consistent pattern of overestimation of time duration. Time was systematically perceived as passing faster while participants were presented with TV series and pornography. Regarding the association between time perception and PG, PPU, and BW, TE did not correlate with any of the indicators of problematic engagement assessed; but TP correlated with several of these indicators. Discussion and conclusions: The present preliminary results showed mixed evidence regarding the involvement of time perception in gaming, pornography use, and binge-watching.

The landscape of open science in behavioral addiction research: Current practices and future directions.

Open science refers to a set of practices that aim to make scientific research more transparent, accessible, and reproducible, including pre-registration of study protocols, sharing of data and materials, the use of transparent research methods, and open access publishing. In this commentary, we describe and evaluate the current state of open science practices in behavioral addiction research. We highlight the specific value of open science practices for the field; discuss recent field-specific meta-scientific reviews that show the adoption of such practices remains in its infancy; address the challenges to engaging with open science; and make recommendations for how researchers, journals, and scientific institutions can work to overcome these challenges and promote high-quality, transparently reported behavioral addiction research. By collaboratively promoting open science practices, the field can create a more sustainable and productive research environment that benefits both the scientific community and society as a whole.

Psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) across cross-cultural subgroups, genders, and sexual orientations: Findings from the International Sex Survey (ISS).

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. METHODS: Responses concerning past-year alcohol use from the participants of the cross-sectional International Sex Survey were considered (N = 62,943; Mage: 32.73; SD = 12.59). Confirmatory factor analysis, as well as measurement invariance tests were performed for 21 countries, 14 languages, three genders, and four sexual-orientation subgroups that met the minimum sample size requirement for inclusion in these analyses. RESULTS: A two-factor model with factors describing 'alcohol use' (items 1-3) and 'alcohol problems' (items 4-10) showed the best model fit across countries, languages, genders, and sexual orientations. For the former two, scalar and latent mean levels of invariance were reached considering different criteria. For gender and sexual orientation, a latent mean level of invariance was reached. CONCLUSIONS: In line with the two-factor model, the calculation of separate alcohol-use and alcohol-problem scores is recommended when using the AUDIT. The high levels of measurement invariance achieved for the AUDIT support its use in cross-cultural research, capable also of meaningful comparisons among genders and sexual orientations.
