Distal and proximal risk factors of problematic cannabis use associated with psychotic-like experiences.

BACKGROUND: Problematic cannabis use is associated with endorsement of psychotic-like experiences (PLEs) in non-clinical samples. However, little is known in regard to predictors of this relationship, which may be relevant to prevention and intervention. In the present research, we investigate impulsivity and cannabis use motives as potential distal and proximal risk factors for PLEs using conditional process analysis. METHODS: Using an online cross-sectional survey of N = 300 students, we assessed endorsement of PLEs using the Community Assessment of Psychic Experiences (CAPE), problematic cannabis use with the Cannabis Use Disorder Identification Test (CUDIT-R), motivations for using cannabis with the Substance Use Motives Measure, and impulsivity using the Urgency and Premeditation, Perseverance, Sensation Seeking, Positive Urgency Impulsive Behaviour Scale (UPPS-P). RESULTS: All three subscales on the CAPE were associated with significantly higher scores on the CUDIT-R. Before and after covarying for sex, we found that higher CUDIT-R scores mediated the relations between lack of perseverance and negative urgency impulsivity with higher PLE symptoms. Furthermore, the indirect effect of cannabis use on the relationship between lack of perseverance and high negative PLE symptoms was only significant at high and moderate levels of depression-coping, but not at low depression-coping motives. CONCLUSION: Impulsivity and depression-coping motives may be distal and proximal psychological risk factors for negative PLEs in the context of problematic cannabis use. Our findings are in line with the broader substance use and mental health literature and may be informative for cannabis use treatment targets.

Adolescent Screen Use: Problematic Internet Use and the Impact of Gender.

OBJECTIVE: The relationship between screen use and problematic internet use (PIU; i.e., internet addiction) amongst adolescents has not been sufficiently explored. Further, there is even less research on how gender is associated with this relationship. The goal of the study was to examine adolescent screen use, PIU, and its impact on day-to-day routines of adolescents. METHODS: Participants were recruited from an outpatient pediatric clinic in São Paulo, Brazil. A total of 180 adolescents completed questionnaires related to their screen use, extracurricular activities, and symptoms of PIU. Univariate and multivariate statistics were used to determine correlates and predictors of PIU, and to explore gender differences. RESULTS: A total of 26.1% of adolescents met the criteria for PIU. There were no significant differences between boys and girls in PIU severity. However, there were significant gender differences in preferred use of the Internet, with boys being more likely to access the Internet to play video games (odds ratio [OR]=27.1) and girls being more likely to socialize with friends (OR=4.51). PIU severity increased proportionally to the number of hours of use of all screen devices with moderate-to-large effect sizes (η2=0.060-0.157). Using screens during meals and missing extracurricular activities were both associated with PIU. CONCLUSION: Though gender was not associated with PIU, both excessive use of screen devices during meals and neglect of offline extracurriculars activities were identified as risk factors for PIU. Prevention measures should consider the impact of gender and associated patterns of motivation and Internet use.

Endorsement of psychotic-like experiences and problematic cannabis use associated with worse executive functioning performance in undergraduates.

BACKGROUND: Emerging adults who endorse more positive psychotic-like experiences (PLEs; bizarre experiences, delusional ideations) may experience greater cannabis-related impairments in executive function. Negative and depressive PLEs are also associated with cannabis use, however, less is known about their relation to executive functioning. Here, we hypothesize that high positive PLEs and cannabis use are associated with worse performance on computerized versions of the Iowa Gambling Task (IGT) and the Card Sorting Task (CST); exploratory analyses are conducted with negative and depressive PLEs. METHODS: We recruited university students (N = 543) who completed an online study consisting of self-report measures of problematic cannabis use (Cannabis Use Disorder Identification Test; CUDIT-R) and PLEs (Community Assessment of Psychotic Experiences; CAPE). Of these, n=270 completed the CST and n=251 completed the IGT. RESULTS: Problematic cannabis use and high endorsement of positive PLEs related to significantly worse performance on the IGT and greater perseverative errors on the CST. In addition, people who endorsed high levels of positive PLEs were also significantly more likely to complete the IGT with less money relative to those who endorsed fewer PLEs, regardless of cannabis use. Further analyses based on negative PLEs revealed a similar pattern for perseverative errors on the CST; depressive PLEs were not related to task performance. CONCLUSION: Findings highlight that problematic cannabis use and more frequent and distressing positive PLEs are associated with poorer executive functioning. Thus, executive functioning may have implications for intervention among those high on both attributes, who are at high risk of onset of psychosis.

A 5-year longitudinal examination of the co-occurring patterns of gambling and other addictive behaviors.

OBJECTIVE: We examined the co-occurring patterns of problem gambling and substance/behavioral addiction severity over a five-year period and the predictors of the different co-occurring patterns of problem gambling and addiction severity. METHODS: We conducted a secondary analysis of the Quinte Longitudinal Study (QLS) data. The QLS is a 5-year prospective longitudinal study of gambling and problem gambling in the Quinte Region in Southern Ontario. The QLS consists of a total of 4,121 participants, including a sample of participants at risk of developing problem gambling. Severity of problem gambling, substance use, and behavioral addictions were used to examine their co-occurring patterns over time. Predictors of the co-occurring patterns included the presence of mental health disorders, personality, stress, happiness, lifesatisfaction, social support, family history, and demographics. RESULTS: Six co-occurring patterns of problem gambling and addiction severity were identified. The largest co-occurring pattern was characterized by concurrent decrease in gambling and other addictive behaviors. Several co-occurring patterns were characterized by moderate-to-severe problem gambling and other addiction severity that remained stable over time. No co-occurring pattern represented a decrease in gambling followed by increase in other addictive behaviors (e.g., addiction substitution). The presence of mental health disorders, stress, and lifesatisfaction significantly predicted the different co-occurring patterns. CONCLUSIONS: Taken together, the results suggest that in a non-clinical sample, gambling and other co-occurring addictive behaviors are likely to simultaneously decrease over time. Comorbidity of mental health disorders significantly influences co-occurring patterns of gambling and other addictive behaviors.

Demographic, gambling, and psychological characteristics of sports bettors in a stratified sample of adults who gamble regularly.

OBJECTIVE: Sports betting accounts for the greatest proportion of online gambling behavior globally and has been linked to various harms. Few studies have examined the average sports bettor profile using stratified samples of adults who gamble regularly. The present study builds upon existing research on the demographic variables of sports bettors and provides an in-depth examination of the clinical and gambling-related factors associated with sports betting. METHOD: Participants (N = 10,039; 53.6% female) consisted of a stratified sample of Canadian adults who endorsed participating in gambling at least once per month in the past year. Participants completed standardized measures assessing demographics, gambling behavior, problem gambling severity, gambling-related harms, gambling motives, and psychological characteristics (e.g., substance use, mental health). RESULTS: About 1,816 participants (18.1%) reported engaging in sports betting in the past year. Sports bettors tended to be younger, male, and employed full-time compared to nonsports bettors. Sports bettors endorsed different patterns of clinical comorbidities and greater substance use. Sports betting was also associated with unique gambling motives and greater time and money spent on gambling. Among participants who endorsed problem gambling, sports betting was associated with greater impulsivity and likelihood of using illicit substances while gambling. CONCLUSIONS: The results highlight the characteristics of individuals who bet on sports, as well as the characteristics of sports bettors with problem gambling which may help to inform the development of targeted prevention and intervention efforts to mitigate the potential harms of sports betting.

This time with feeling: In-play sports betting as a vehicle for emotion regulation.

OBJECTIVE: The purpose of this research was to assess factors (i.e., emotion regulation, impulsivity) that motivate in-play sports betting. Specifically, we examined whether individuals report increased excitement after placing an in-play bet and whether trait negative and positive urgency moderate the effect of emotion regulation motives on in-play betting frequency. METHOD: Three cross-sectional studies were conducted, each following a major sporting event: Superbowl LVI (56) (Study 1), March Madness Final (Study 2), and Union of European Football Associations Champions League Final (Study 3). Participants were U.S. (NStudy 1 = 111; NStudy 2 = 121) and U.K. (NStudy 3 = 239) residents who reported placing at least one in-play bet during the respective sporting events. Participants completed self-report measures of excitement, emotion regulation motives, in-play betting frequency, problem gambling, and trait affective impulsivity. Data from the three studies were pooled to conduct an integrative data analysis (IDA). RESULTS: Participants reported increased excitement after placing an in-play bet (p < .001). In bivariate analyses, greater emotion regulation motives were associated with greater in-play betting frequency (p < .05). In moderation analyses, emotion regulation motives interacted with trait negative (p < .001) and positive urgency (p < .001) to predict in-play betting frequency, such that the bivariate effects were amplified among those higher (relative to lower) in trait affective impulsivity. CONCLUSIONS: In-play sports betting is an exciting activity that people who gamble may engage in to regulate their emotions. These effects are amplified in those with high trait affective impulsivity. Responsible gambling tools such as mandatory play breaks may discourage the continuation of impulsive betting episodes.

Cognitive-behavioral treatment for gambling harm: Umbrella review and meta-analysis.

The aim of the current umbrella review and meta-analysis was to evaluate the methodological rigor of existing meta-analyses on cognitive-behavioral treatment (CBT) for gambling harm. The Cochrane Database of Systematic Reviews, PsycINFO, and PubMed were searched for meta-analyses of CBT for gambling harm among individuals aged 18 years and older. The search yielded five meta-analyses that met inclusion criteria, representing 56 unique studies and 5389 participants. The methodological rigor for one meta-analyses was rated high, two were moderate, and two were critically low. Including only moderate- to high-quality meta-analyses, a robust variance estimation meta-analysis indicated that CBT significantly reduced gambling disorder severity (g = -0.91), gambling frequency (g = -0.52), and gambling intensity (g = -0.32) relative to minimal and no treatment control at posttreatment, suggesting 65%-82% of participants receiving CBT will show greater reductions in these outcomes than minimal or no treatment controls. Overall, there is strong evidence for CBT in reducing gambling harm and gambling behavior, and this evidence provides individuals, clinicians, managed care companies, and policymakers with clear recommendations about treatment selection.

Psychometric properties of the generalised version of the Screener for Substance and Behavioural Addictions (SSBA-G): A comprehensive screening tool for substance-related and behavioural addictions.

Assessing addictive behaviours comprehensively and efficiently is a challenge in both research and clinical practice. Consequently, we tested the psychometric properties of the Generalized Screener for Substance and Behavioural Addictions (SSBA-G), a novel, brief screening tool measuring functional impairment resulting from both substance and behavioural addictions. The SSBA-G was developed from the Screener for Substance and Behavioural Addictions (Schluter et al., 2018) and tested in four samples including university students in Canada (n = 481) and the US (n = 164) as well as community adults in Canada (n = 301), and Hungary (n = 79). Confirmatory factor analysis supported the hypothesized bifactor model of the SSBA-G. Receiver-operation characteristic analyses revealed high differentiation accuracy (AUC=0.86-.95), as well as identical ideal cut points across the Substance Addiction (SSBA-G-S) and Behavioural Addiction (SSBA-G-B) Subscales. Results indicated good-to-excellent sensitivity and moderate-to-good specificity. The SSBA-G demonstrated excellent internal consistency and test-retest reliability as well as promising concurrent validity in relation to the original SSBA and additional questions regarding addiction-related impairment. The SSBA-G also showed good convergent and divergent validity with indicators of general mental health. These results indicate that the SSBA-G is a psychometrically sound and efficient measure of addiction-related impairment across substances and excessive behaviours.

Addiction substitution and concurrent recovery in gambling disorder: Who substitutes and why?

Objectives: When individuals recover from gambling disorder, their involvement in other potentially addictive substances and behaviors may also subsequently increase (substitution) or decrease (concurrent recovery). The objectives of this study were to identify and compare recovery processes associated with substitution and concurrent recovery in gambling disorder. Methods: A mixed-method study was conducted with 185 people who were recovered from gambling disorder. Semi-structured interviews were used to: (i) establish onset and recovery of gambling disorder as well as other substance and behavioral addictions; and (ii) assess processes (e.g., reasons, emotional state, helpfulness) associated with addiction substitution and concurrent recovery. Participants also completed a survey assessing demographic characteristics, gambling behaviors, and psychological characteristics to compare demographic and clinical differences between participants who engaged in addiction substitution, concurrent recovery, or neither (controls). Results: The most frequently reported reason for engaging in addiction substitution was as a substitute coping mechanism. The most reported reason for engaging in concurrent recovery was due to the addictions being mutually influenced. Negative emotional states were common when engaging in both addiction substitution and concurrent recovery. Although the three groups did not differ on gambling characteristics, addiction substitution was associated with greater underlying vulnerabilities including childhood adversity, impulsivity, emotion dysregulation, and, maladaptive coping skills. Conclusion: Transdiagnostic treatments that target the underlying mechanisms of addictions may reduce the likelihood of engaging in addiction substitution.

Dispositional and contextual correlates of in-play sports betting and related harms: A 2-week ecological momentary assessment study.

OBJECTIVE: In-play betting is a novel form of sports betting that allows players to make continuous bets during a game. The present study examined the dispositional and contextual correlates of in-play sports betting and related harms. METHOD: Participants were 84 individuals (73.81% men, Mage = 41.02) who engaged in in-play betting. Participants first completed an online questionnaire including measures of problem gambling severity, childhood trauma, impulsivity, and emotion dysregulation. Participants then completed a 14-day ecological momentary assessment (EMA) study involving completing brief surveys twice per day. EMA surveys assessed in-play betting behaviors, motives, contexts, and harms. RESULTS: A total of 1,365 EMA surveys were completed, of which 32.89% involved placing at least one in-play bet. A total of 77 (91.67%) participants placed at least one in-play bet during the study period. Participants reported greater in-play betting involvement (the number of bets placed, money spent) and an increased likelihood of experiencing in-play betting-related financial and relationship harms when using substances while betting and when motivated to place in-play bets by an interest in sports or to "be in the game." Participants, who used substances during a greater proportion of in-play betting occasions, who more frequently endorsed coping motives for in-play betting, and who exhibited elevated problem gambling severity, reported greater in-play betting involvement and the likelihood of experiencing in-play betting-related harms overall. CONCLUSIONS: Responsible gambling initiatives targeting contextual risk factors, such as using alcohol and cannabis while in-play betting, may help to reduce the intensity of in-play betting and its associated harms.

Who makes in-play bets? Investigating the demographics, psychological characteristics, and gambling-related harms of in-play sports bettors.

Background and aims: Sports betting has increased markedly in recent years, in part due to legislative changes and the introduction of novel forms of sports betting (e.g., in-play betting). Some evidence suggests that in-play betting is more harmful than other types of sports betting (i.e., traditional and single-event). However, existing research on in-play sports betting has been limited in scope. To address this gap, the present study examined the extent to which demographic, psychological, and gambling-related constructs (e.g., harms) are endorsed by in-play sports bettors relative to single-event and traditional sports bettors. Methods: Sports bettors (N = 920) aged 18+ from Ontario, Canada completed an online survey containing self-report measures of demographic, psychological, and gambling-related variables. Participants were classified as either in-play (n = 223), single-event (n = 533), or traditional bettors (n = 164) based on their sports betting engagement. Results: In-play sports bettors reported higher problem gambling severity, endorsed greater gambling-related harms across several domains, and reported greater mental health and substance use difficulties compared to single-event and traditional sports bettors. There were generally no differences between single-event and traditional sports bettors. Discussion: Results provide empirical support for the potential harms associated with in-play sports betting and inform our understanding of who may be at risk for increased harms associated with in-play betting. Conclusions: Findings may be important for the development of public health and responsible gambling initiatives to reduce the potential harms of in-play betting, particularly as many jurisdictions globally move towards legalization of sports betting.

A scoping review of the association between loot boxes, esports, skin betting, and token wagering with gambling and video gaming behaviors.

Background and aims: Many new digital gambling-like activities such as loot boxes, esports betting, skin betting, and token wagering have recently emerged and grown in popularity. This scoping review aimed to: (a) synthesize the existing empirical research literature on gambling-like activities and their associations with gambling and video gaming behaviors, including problem gambling and video gaming; (b) identify sociodemographic, psychological, and motivational factors associated with engagement in gambling-like activities; and (c) identify research gaps and areas for further research. Methods: A systematic search of Ovid, Embsco, and ProQuest databases and Google Scholar was conducted in May 2021 and last updated in February 2022. The search yielded a total of 2,437 articles. Articles were included in the review if they were empirical studies that contained quantitative or qualitative results regarding the relationship between gambling-like activities and gambling or gaming. Results: Thirty-eight articles met inclusion criteria and were included in the review. Overall, the review results suggest that all forms of gambling-like activities were positively associated with gambling and gaming with small to medium effects. Gambling-like activity participation was also positively associated with mental distress and impulsivity. Gaps identified included a lack of inquiry into skin betting and token wagering, a lack of diversity in the research methods (i.e., mainly cross-sectional surveys), and a paucity of research that includes more ethnically, culturally, and geographically diverse populations. Discussion: Longitudinal studies with more representative samples are needed to examine the causal link between gambling-like activities and gambling and video gaming.

Symptoms of depression (not anxiety) mediate the relationship between childhood sexual abuse and compulsive sexual behaviors in men

Objective: Childhood sexual abuse is associated with compulsive sexual behavior, depression, and anxiety in men. Furthermore, both depression and anxiety have been linked to compulsive sexual behaviors. However, whether anxiety and depression mediate the relationship between childhood sexual abuse and compulsive sexual behaviors has yet to be tested. We investigated whether symptoms of depression and anxiety mediate the relationship between childhood sexual abuse and compulsive sexual behaviors in 222 men seeking treatment for such behaviors. Methods: Participants completed the Sexual Compulsivity Scale, Childhood Trauma Questionnaire, Beck Depression Inventory, and Beck Anxiety Inventory. A cross-sectional parallel mediation analysis was conducted. Results: The prevalence of childhood sexual abuse in our sample was 57%. Significant correlations were found between childhood sexual abuse and compulsive sexual behaviors, depression, and anxiety. The results of the mediation analyses suggested that depression (B = 0.07, standard error [SE] = 0.03, 95%CI 0.02 to 0.15), but not anxiety (B = 0.02, SE = 0.02, 95%CI -0.2 to 0.07), mediated the link between childhood sexual abuse and compulsive sexual behaviors. The pattern of our results remained the same when controlling for other types of childhood trauma. Conclusions: Depression, not anxiety, appears to mediate the relationship between childhood sexual abuse and compulsive sexual behaviors in men. Future research that tests our mediation analyses using a prospective longitudinal study would be highly informative.

Self-Generated Motives of Social Casino Gamers.

Social casino games have achieved widespread popularity, and are accessed by more than 85 million people each day. Yet, why people play social casino games is largely unknown. To address this gap, an inductive approach was taken to better understand the motives for playing social casino games, as well as the motives for transitioning from social casino gaming to gambling and vice versa. To this end, 269 social casino gamers were asked to provide a ranked list of their motives for playing social casino games. Additionally, we asked participants their motivations for transitioning from gambling to social casino gaming (n = 202) or vice versa (n = 67). A total of 795, 605, and 201 unique responses describing motives for playing social casino games, transitioning from social casino gaming to gambling, and transitioning from gambling to social casino gaming, respectively, were analyzed using a thematic content analysis. The most frequently endorsed motive for playing social casino games was for enhancement (e.g., fun, challenge). Participants also noted playing to earn rewards, including money, and for social reasons. Several motives linked social casino game play to gambling. These included: to hone gambling-related 'skills', a desire to transition to gambling to win real money, and as a gambling harm-reduction strategy. Motives for playing social casino games did not differ significantly between those who first gambled and then transitioned to social casino gaming and vice versa, suggesting that once people begin playing social casino games, they have similar motives for continued engagement. The present study contributes to understanding the immense popularity of social casino games and their links to gambling.

Emotion dysregulation mediates the relationship between adverse childhood experiences and problematic gaming.

Gaming disorder (i.e., gaming addiction) is a relatively common mental health disorder with a worldwide prevalence rate of 3.05%. In the present research, we examined whether emotion dysregulation mediates the relation between adverse childhood experiences and problematic gaming in two samples of current video game players. The first sample consisted of 1,262 students recruited from five universities across Canada. The second sample comprised 417 community adults residing in Canada. Both samples of participants completed an online survey which included measures of adverse childhood experiences, problematic gaming, and emotion dysregulation. A total of 45.64% (n = 576) in the university sample and 49.76% (n = 205) in the community sample met the threshold for problematic gaming. In the student sample, adverse childhood experiences were positively associated with problematic gaming. In contrast, there was no significant association between adverse childhood experiences and problematic gaming in the community sample. In both samples, adverse childhood experiences were positively associated with emotion dysregulation, and emotion dysregulation was positively associated with problematic gaming. Importantly for the present research, emotion dysregulation mediated the relationship between adverse childhood experiences and problematic gaming in both the university and community sample. Although adverse childhood experiences are distal and static risk factors for problematic gaming, emotion dysregulation is a more proximal and modifiable risk factor. The results suggest that increasing adaptive emotion regulation skills may decrease the risk of problematic gaming among individuals who have experienced an adverse childhood experience.

Neuroimaging of Dopamine Transporter Density in the Striatum of Disordered Gamblers.

The aim of the present research was to add to the growing literature on dopamine and gambling disorder (GD) by assessing whether GD is associated with dopamine transporter (DAT) density in the ventral striatum compared to healthy controls and whether DAT density was associated with key characteristics of GD (e.g., abstinence, craving). In a cross-sectional investigation using single-photon emission computed tomography with a technetium-99m-labeled tropane derivative as a radiotracer with SPECT imaging, fifteen participants with GD and 15 controls (non-gambling individuals, matched for age, gender, handedness, and smoking status) were measured. The GD group completed self-reported questionnaires regarding gambling. Striatal DAT density did not differ between the two groups. Conversely, striatal DAT density correlated significantly with various measures of recent gambling, but not with measures of chronic gambling. Multivariate analysis, adjusted for age and smoking status, showed that DAT density in the left striatum correlated positively with time spent gambling and gambling craving in the last month, whereas DAT density in the right striatum correlated negatively with abstinence self-efficacy. The results suggests that DAT density in the striatum is associated with recent gambling activity and gambling expectation.

A Systematic Review of Eye-Tracking Studies of Gambling-Related Attentional Biases.

Previous research has identified attentional biases towards addiction-related stimuli, including gambling-related stimuli. Eye-tracking is considered the gold standard methodology for measuring attentional biases, yet no review to date has examined its use in measuring gambling-related attentional biases. This systematic review synthesized the literature using eye-tracking to examine attentional biases among people who gamble. We reviewed articles from Web of Science and PubMed that were published from 1990 to 2021. A total of 11 articles were included, with sample sizes ranging from 38 to 173 participants. Of these studies, seven examined attentional biases for gambling-related visual stimuli. These seven studies provided support that gambling can result in the development of an attentional bias for gambling-related stimuli. With respect to correlates of gambling-related attentional biases, there were mixed results. Some studies identified significant positive associations between gambling-related attentional biases and psychosocial variables, such as problem gambling severity, gambling expectancies, gambling cravings, gambling motives, depressive symptom severity, alcohol use severity, daily stress, affective impulsivity, and immersion. Four studies examined attentional biases for responsible gambling messaging and advertisements, finding that both people who do and do not gamble attend less to responsible gambling messaging compared to other types of information such as the betting odds. Research using eye-tracking to examine attentional biases among people who gamble is in its infancy. Yet, the preliminary results support the identification of attentional biases using the gold-standard methodology. Further studies are needed to examine the correlates and potential clinical utility of assessing gambling-related attentional biases using eye-tracking.

Individual differences and predictors of general awareness in problem gambling.

In Canada, up to 3% of individuals have or are at risk of gambling disorder. Among these individuals, a lack of awareness of their problem gambling is a common barrier to treatment and negatively affects treatment adherence. A secondary analysis was conducted on data from 1346 individuals (mean age = 43.4, SD = 14.4; 54.3 % male) with problem gambling who did and did not perceive having a problem with their gambling as assessed by the fifth item of the Problem Gambling Severity Index, "In the past twelve months, how often have you felt that you might have a problem with gambling?" Additionally, we investigated predictors of increased general awareness at 12-month follow-up. At baseline, individuals who perceived a problem with their gambling experienced more gambling-related harms (OR = 1.714), had greater total gambling losses (OR = 1.067), were more likely to have a family history of problem gambling (OR = 2.143), experienced a greater loss of control (OR = 1.313) and more often gambled alone than with others (OR = 0.879), accounting for 26.6 % of the variance in general awareness. Baseline problem awareness was positively associated with attempts to cut down or control gambling at follow-up (χ2=11.350,p<.001), but negatively associated with remission (χ2=18.392,p<.001). Increases in awareness were related to an increase in the number of gambling-related harms, gambling involvement, impaired control, and lower educational attainment, explaining 35.5% of the variance in increased general awareness. The results indicate that experiencing more gambling-related harms increases the salience and awareness of problem gambling, and that awareness is also associated with an individual's gambling context, their loss of control, and their level of gambling involvement. The findings highlight the importance of gambling harms as they pertain to general awareness and suggest that improving the recognition of gambling harms could be beneficial for the prevention and intervention of gambling disorder.

Psychometric properties of the Smartphone Addiction Inventory - Short Form (SPAI-SF) in Brazilian adolescents.

The Smartphone Addiction Inventory - Short Form (SPAI-SF) is shorter version (10 items) of the original version of SPAI (26 items). In this study, we aimed to: (i) adapt and test the internal structure of the SPAI-SF, using confirmatory factor analysis (CFA), multigroup confirmatory factor analysis (MGCFA), and network analysis; (ii) analyze the internal consistency, temporal stability, criterion, predictive and construct validities of the SPAI-SF. A total of 392 adolescents (M = 12.76; SD = 1.00) completed the following measures: demographic questionnaire, SPAI-SF, Smartphone Addiction Scale - Short Version (SAS-SV), and the Internet Addiction Test (IAT). The CFA showed good fit indices with the original four factors, and MGCFA indicated measurement invariance for gender. Network analysis provided an understanding of the core symptoms of problematic smartphone use (PSU) for both boys and girls. The intraclass correlation coefficient (ICC) was 0.865 (95% CI: 0.841 - 0.887) and indicated a robust temporal stability. The instrument demonstrated acceptable overall reliability measured by Cronbach's alpha and McDonald's Omega criteria (α = 0.722; ω = 0.725) and did not show floor and ceiling effects. The scale's significant correlations demonstrated convergent and criterion validities of the SPAI-SF with SAS-SV, IAT, and Smartphone usage data. The SPAI-SF is a reliable instrument to detect PSU in adolescents.
