RESUMO

Problematic cannabis use is highly prevalent among postsecondary students. Consequently, there is a need to examine risk factors associated with problematic cannabis use in this population. The present study investigated whether emotion dysregulation mediates the relationship between adverse childhood experiences (ACEs) and problematic cannabis use, and whether affective impulsivity (negative and positive urgency) uniquely moderates this relationship. Participants consisted of current cannabis users (N = 586) recruited from five universities across Canada. Participants completed an online survey containing self-report measures of ACEs, emotion dysregulation, negative and positive urgency, and problematic cannabis use. Among the sample of postsecondary students, 36% (n = 213) met the threshold for problematic cannabis use. Moderated-mediation analyses revealed that ACEs were positively associated with emotion dysregulation and problematic cannabis use. There was also a significant indirect effect of emotion dysregulation on the association between ACEs and problematic cannabis use at moderate and high (but not low) levels of negative urgency, and at moderate and high (but not low) levels of positive urgency. The moderated-mediation models remained significant when controlling for other facets of impulsivity. Results suggest that elevated levels of emotion dysregulation and urgency are important proximal risk factors for problematic cannabis use among postsecondary students with a history of ACEs. While ACEs cannot be modified given their occurrence in the past, interventions that aim to build mindfulness and adaptive emotion regulation skills may be beneficial for reducing the likelihood that these students will engage in impulsive behaviors, such as cannabis use, when experiencing emotional distress.

RESUMO

Background: Cannabis use in young adulthood has been associated with exposure to traumatic events and posttraumatic stress disorder (PTSD). Coping motives for cannabis use represent one mechanism linking PTSD with cannabis problems, yet some individuals with PTSD consider their cannabis use to be medicinal in nature. While a medicinal orientation to cannabis overlaps conceptually with coping motives, it could be associated with unique cannabis outcomes. Objectives: This study examined trauma-related coping motives and medicinal cannabis orientation as mediators of the association between PTSD symptoms and cannabis outcomes in young adults. Method: Data came from an online survey of 212 university students (M age = 19.41; 70.3% Women; 43.4% White) who used cannabis in the past month and endorsed a traumatic life event. Path analyses examined associations of PTSD symptoms with past month cannabis frequency and problems through medicinal cannabis orientation (i.e., number of mental health symptoms that cannabis is used to manage) and trauma-related coping motives. Results: PTSD symptoms were associated with trauma-related coping motives but not with medicinal cannabis orientation. Both trauma-related coping motives and medicinal cannabis orientation were uniquely associated with greater cannabis use frequency, but only trauma-related coping motives were associated with greater cannabis problems. There were significant indirect relationships from PTSD symptoms to cannabis use frequency and problems through trauma-related coping motives but not through medicinal cannabis orientation. Conclusions: Results support unique contributions of trauma-related coping motives and medicinal cannabis orientation to cannabis outcomes and suggest that trauma-related coping motives are specifically implicated in the link between PTSD and cannabis problems.

RESUMO

The Gambling Craving Scale (GACS) is a multifaceted measure of gambling craving. Initial validation work by Young and Wohl (2009) in university student samples showed that the GACS had a three-factor structure capturing dimensions of Desire, Anticipation, and Relief. Despite its potential clinical utility as a measure of craving, the GACS has yet to be validated in people seeking treatment for gambling problems. Accordingly, we examined the psychometric properties in a sample of people (N = 209; Mage = 37.66; 62.2% female) participating in a randomized controlled trial testing a novel online treatment for problem gambling. We predicted the GACS would have a three-factor structure. In addition, we also examined measurement invariance across sex and problem gambling risk status. Finally, we assessed concurrent validity of the factors with other measures of problem gambling severity and involvement. Exploratory structural equation modeling findings supported a three-factor structure that was invariant across the groups tested. Each of the Desire, Anticipation, and Relief subscales were significant positive predictors of problem gambling severity and symptoms, and some form of gambling behaviour. Findings show the GACS is a promising scale to assess multidimensional craving experiences among people in treatment for gambling problems.

RESUMO

BACKGROUND: Alcohol misuse is common and causes substantial harm. Internet-delivered cognitive behaviour therapy (ICBT) is effective in reducing alcohol misuse; however, the literature investigating how treatment outcomes are impacted by patients' preferences for therapist- versus self-guided ICBT for alcohol misuse is sparse. METHODS: In this preference trial, 74 eligible patients (who reported ≥ 14 drinks in the previous week and obtained scores suggesting hazardous or harmful drinking) chose between enrolling in either therapist- or self-guided ICBT for alcohol misuse. We investigated whether those who chose therapist- versus self-guided ICBT differed in their (a) drinking outcomes-as measured by Timeline Follow-Back (TLFB) and heavy drinking days (HDD) at post-treatment and 3-month follow-up-and (b) post-treatment ICBT engagement and satisfaction. RESULTS: The majority (81.1%) of eligible patients chose therapist-guided ICBT. These patients reported higher psychotropic medication use, drinking difficulties, and anxiety symptoms. For both the therapist- and self-guided patients, a modified intention-to-treat analysis revealed large within-group treatment effects for TLFB (ß = - 2.64, SE 0.66; p < 0.001) and HDD (ß = - 0.34, SE 0.07; p < 0.001), with large pre-to-post-treatment Cohen's effect sizes of d = 0.97 (95% CI [0.49, 1.45]) for TLFB and d = 1.19 (95% CI [0.69, 1.68]) for HDD. The interaction comparing the effects of therapist- to self-guided ICBT over time was not significant for TLFB (p = 0.34) or HDD (p = 0.06). With treatment, for both therapist- and self-guided patients, there was a significant improvement in drinking difficulties, cravings, and confidence with controlling cravings, as well as in anxiety, depression, and functional impairment. Further, the majority (75.7%) of patients completed five or more lessons, as well as reported overall satisfaction with the treatment (88.9%) and increased confidence in managing their symptoms (86.7%); these outcomes also did not differ between therapist- and self-guided patients. CONCLUSIONS: The current study shows that ICBT for alcohol misuse is associated with reduced drinking and comorbid mental health difficulties over time, irrespective of whether patients chose to complete the course on their own or with therapist guidance.

RESUMO

BACKGROUND: Alcohol-induced injury is one of the leading causes of preventable morbidity and mortality. We investigated the relationship between impulsive personality and physical injury (e.g. falls, sports), and whether peak drinking quantity specifically, and/or risky behaviour more generally, mediates the relationship between impulsivity and injury in undergraduates. METHOD: We used data from the winter 2021 UniVenture survey with 1316 first- and second-year undergraduate students aged 18-25 years (79.5% female) from five Canadian Universities. Students completed an online survey regarding their demographics, personality, alcohol use, risky behaviours, and injury experiences. Impulsivity was measured with the substance use risk profile scale, past 30-day peak alcohol use with the quantity-frequency-peak Alcohol Use Index, general risky behaviour with the risky behaviour questionnaire, and past 6-month injury experience with the World Health Organization's (2017) injury measurement questionnaire. RESULTS: Of 1316 total participants, 12.9% (n = 170) reported having sustained a physical injury in the past 6 months. Mean impulsivity, peak drinking quantity, and risky behaviour scores were significantly higher among those who reported vs. did not report injury. Impulsivity and peak drinking quantity, but not general risky behaviour, predicted injury in a multi-level generalized mixed model. Mediation analyses supported impulsivity as both a direct predictor of physical injury and an indirect predictor through increased peak drinking (both p < .05), but not through general risky behaviour. CONCLUSION: Results imply emerging adults with impulsive tendencies should be identified for selective injury prevention programs and suggest targeting their heavy drinking to decrease their risk for physical injury.

RESUMO

Cannabis use and social anxiety disorder (SAD) are prevalent during emerging adulthood. Previous work has demonstrated that SAD is related to cannabis use in adults; however, less is known about what correlates relate to this association in emerging adults. A subsample of individuals ages 18-25 years old from the NESARC-III (N = 5194) was used to (a) evaluate the association between cannabis use and SAD and (b) examine what correlates may be associated with cannabis use and SAD in emerging adulthood. Weighted cross-tabulations assessed sociodemographics and lifetime psychiatric disorder prevalence estimates among the emerging adult sample. Multinomial logistic regressions examined associations between sociodemographics and psychiatric disorders and four groups (i.e., no cannabis use or SAD; cannabis use only; SAD only; cannabis use + SAD). The prevalence of co-occurring cannabis use and SAD was 1.10%. Being White, a part-time student, or not a student were associated with increased odds of having co-occurring cannabis use + SAD (OR range: 2.26-3.09). Significant associations also emerged between major depressive disorder, bipolar I disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder and co-occurring cannabis use + SAD (AOR range: 3.03-19.05). Results of this study may have implications for better identifying and screening emerging adults who are at risk of co-occurring cannabis use and SAD.

RESUMO

Many Canadian emerging adults (ages 18-25 years) use cannabis, with 60 % of past-three-month users experiencing one or more cannabis-related problems (i.e., adverse consequences of use). While psychotic-like experiences (PLEs) and cannabis problems overlap, little is known about the mechanisms explaining this link. One hypothesis is that PLEs are distressing and give rise to anxiety, with which emerging adults attempt to cope through increased cannabis use, in turn increasing their risk for cannabis-related problems. We tested a chained-mediational model to determine if anxiety and coping-with-anxiety motives for cannabis use sequentially mediated the link between PLEs and cannabis problems in emerging adult undergraduates; a conditional process model tested for moderation by sex. Emerging adult cannabis users (N = 413; mean [SD] age = 19.1 [1.5] years; 71.9 % female) from five Canadian universities provided cross-sectional, self-report survey data in fall 2021. Validated measures of PLEs, anxiety, cannabis coping-with-anxiety motives, and cannabis-related problems were administered. Path analyses supported the hypothesized chained mediational indirect effect (b = 0.027, 95 % bootstrap CI [0.012, 0.050]). No direct effect was found (p =.698), suggesting that the PLEs-to-cannabis problems association is fully explained by anxiety and cannabis coping-with-anxiety motives. Inconsistent with hypotheses, mediation did not depend on sex (95 % CIs crossed zero); therefore, anxiety and cannabis coping-with-anxiety motives explain the link between PLEs and cannabis problems in emerging adults regardless of their sex. Results highlight anxiety and cannabis coping-with-anxiety motives as potentially important intervention targets in cannabis-using emerging adults with PLEs, possibly preventing the development/worsening of cannabis-related problems.

RESUMO

Heavy drinking and smoking have been found to be among the leading causes of morbidity and mortality within Indigenous youth in North America. The focus of this study was to examine the relative roles of cultural identity, parent-child communication about the harms of substance use (SU), and perception about peers' opinions on heavy drinking and cigarette smoking among Indigenous youth. Strong Indigenous cultural identity, parent-child communication about SU, and affiliation with peers who do not use and/or who disapprove of substance use were all expected to reduce risk for heavy drinking and smoking. Substance use beliefs were hypothesized to mediate these effects. Youth (N = 117; Mage = 14.07; grades 6-11) from two Indigenous communities in Quebec completed self-reports. Consistent with the hypotheses, strong cultural identity predicted increased negative beliefs about substance use, which predicted reduced drinking and smoking. Similarly, affiliating with peers who did not use alcohol predicted decreased positive beliefs about alcohol use, which predicted reduced drinking. Affiliating with peers who did not smoke cigarettes predicted reduced cigarette smoking. Parental influences were not supported in this model. Intervention strategies may benefit from targeting cultural identity, peer groups, and substance use beliefs among Indigenous youth.

RESUMO

Background and Aims: Problem gambling constitutes a public health concern associated with psychopathological comorbidity, substance use, and financial difficulties. Most individuals with gambling problems avoid counseling services due to perceived stigma and their preference for self-reliance. Treatment accessibility could be improved through web-based interventions. Methods: We recruited 360 individuals with gambling problems and randomized them to a web-based intervention (n = 185) or an active control group consisting of a self-help manual for problem gambling (n = 175). The primary outcome was the number of days of gambling in the last 30 days. Secondary outcomes included money spent in the last 30 days, time gambling in the last 7 days, gambling-related problems, consumption of alcohol and cigarettes, and psychopathological comorbidity measured at posttreatment and 6-month follow-up. Results: The primary outcome decreased significantly for both groups, with no significant difference between the groups. There were significant group × time interactions according to the Gambling Symptom Assessment Scale (F = 8.83, p <0 .001), the Problem Gambling Severity Index (F = 3.54, p = 0.030), for cigarettes smoked in the last 7 days (F = 26.68, p < 0.001), the Patient Health Questionnaire-9 (F = 19.41, p <0 .001), and the Generalized Anxiety Disorder-7 (F = 41.09, p <0 .001) favoring the intervention group. We experienced an overall high dropout rate (76%). Conclusions: Win Back Control seems to be an effective low-threshold treatment option for individuals with gambling problems that might otherwise be unapproachable for outpatient treatment services. Nevertheless, the high dropout rate should be considered when interpreting the study results, as they may have introduced a degree of variability.

RESUMO

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.

RESUMO

Tension reduction theory suggests anxious people gamble to cope with negative affect. Literature demonstrates mixed associations between anxiety and gambling behaviours, hence, the important of examining moderators. This study examined how impulsivity moderated anxiety and problem gambling as well as gambling to cope. Given key gender differences, moderation was examined across genders. A sample of 484 undergraduate students who endorsed gambling behaviours completed anxiety, impulsivity, and problem gambling measures. Results showed men with higher levels of anxiety scored higher on problem gambling at both high (B = 0.706, SE = 0.073, p < 0.0001, f2 = 0.20) and low (B = 0.262, SE = 0.103, p = 0.01, f2 = 0.01) impulsivity, though the effect sizes were much larger for men with high impulsivity. This moderation effect was not found in women (B = 0.000, SE = 0.009, p = 0.959). Results showed men with higher levels of anxiety scored higher on coping motives for gambling at both high (B = 0.253, SE = 0.046, p < 0.0001, f2 = 0.06) and low B = 0.141, SE = 0.063, p = 0.026, f2 = 0.01) impulsivity, though the effect sizes were larger for men with high impulsivity. Again, this moderation effect was not found in women (B = - 0.101, SE = 0.006, p = 0.100). Findings from this may help inform impulsivity-focused interventions, such as strengthening impulse control and instilling more adaptive coping strategies to lower gambling risk among university men.

RESUMO

Background: It is important to identify students who would benefit from early interventions to reduce harmful drinking patterns and associated consequences. the Brief Young Adult Alcohol Consequences Questionnaire (B-YAACQ) could be particularly useful as a screening tool in university settings. Objectives. The present study examined the utility of the B-YAACQ to distinguish among students at-risk for problematic alcohol use as measured by the AUDIT. Objectives: The present study examined the utility of the B-YAACQ to distinguish among students at-risk for problematic alcohol use as measured by the AUDIT. Methods: A sample of 6382 students (mean age=20.28, SD=3.75, 72.2% females) from seven countries (i.e., U.S., Canada, South-Africa, Spain, Argentina, Uruguay, England) completed the B-YAACQ, the AUDIT and different measures of alcohol use. Results: ROC analyses suggested that a cutoff score of 5 maximized the YAACQ's discrimination utility to differentiate between students at low versus moderate/high risk in the total sample and across countries (except in Canada, where the cutoff was 4). In addition, a cutoff of 7 differentiated between students at low/moderate versus high risk in the total sample, while cutoffs of 10, 9, 8 and 7 differentiate between students at low/moderate versus high risk in Uruguay, U.S and Spain (10), Argentina (9), England (8), and Canada and South-Africa (7), respectively. Students classified at the three risk levels (i.e., low, moderate and high) differed in age (i.e., a younger age was associated with higher risk) and drinking patters (i.e., higher drinking frequency, quantity, binge drinking and AUDIT and B-YAACQ scores in the higher risk groups). Conclusions: This study suggest that the B-YAACQ is a useful tool to identify college students at-risk for experiencing problematic patterns of alcohol use.

RESUMO

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.

RESUMO

OBJECTIVE: Cannabis is commonly used by Canadian emerging adults (ages 18-25 years), many of whom attend post-secondary institutions. Frequent cannabis use is linked with psychotic-like experiences (PLEs); however, the exact nature of this association remains unclear. Anxiety symptoms may mediate this association, as they are prevalent in emerging adults and have been independently linked with both cannabis use and PLEs. Past work found that anxiety mediated the association between cannabis use frequency and attenuated positive psychotic symptoms (further along the psychosis continuum than PLEs), however this research had yet to be validated in the Canadian population, and trait rather than state anxiety (frequency of anxiety symptoms) was studied. Thus, our primary objective was to examine if anxiety symptoms mediated the association between cannabis use frequency and PLEs in Canadian emerging adult undergraduates. Despite known sex differences in cannabis use, expression of anxiety, and PLEs, past work did not evaluate the potential impact of biological sex on the anxiety-mediated model, and thus is the secondary objective of the present study. METHODS: 1,266 first-/second-year emerging adult undergraduates from five Canadian universities provided cross-sectional, self-report survey data in fall 2021 semester. Validated measures of cannabis use frequency, anxiety, and PLEs were administered. RESULTS: Path analyses supported mediation from cannabis use to PLEs through anxiety (b = 0.07, P < 0.001, 95% bootstrap CI [0.03, 0.10]). No direct effect was found (P = 0.457), suggesting that the cannabis-to-PLEs association was mediated by anxiety. Mediation did not depend on biological sex (i.e., bootstrapped 95% CIs crossed zero). CONCLUSIONS: Anxiety symptoms mediated the association between cannabis use and PLEs in emerging adults regardless of their biological sex. Assuming replication in prospective research, results highlight anxiety as an important intervention target in frequent cannabis-using emerging adults, to potentially prevent development/worsening of PLEs, and in turn psychotic illness.

RESUMO

Background: Gray's original Reinforcement Sensitivity Theory (RST) posits that an oversensitive behavioral inhibition system (BIS) may increase risk for negative-reinforcement-motivated drinking, given its role in anxiety. However, existing data provides mixed support for the BIS-alcohol use association. The inconsistent evidence is not surprising, as the revised RST predicts that the behavioral approach system (BAS) should moderate the effect of the BIS on alcohol use. A strong BAS is thought to bring attention to the negatively reinforcing effects of alcohol, leading to problem drinking among those with a strong BIS. While emerging results support this interaction, we still have much to learn about the mechanisms underlying this effect on alcohol use. Accordingly, we examined motives for alcohol use as mediators of the joint associations of the BIS and the BAS on drinking behaviors. Specifically, our central hypothesis was that individuals with a strong BIS and a strong BAS would endorse increased negative reinforcement motives for drinking (coping and conformity motives), which in turn would predict heavy drinking and alcohol problems. Method: Participants (N=346; 195 women) completed study measures as part of the baseline assessment for a larger study. Results: Overall, results partially supported the hypotheses. Mediated moderation analyses showed that the indirect effect of the BIS on alcohol problems, through coping and conformity motives, was strongest at high levels of the BAS. This effect was not supported for alcohol use. Conclusions: Our findings suggest that clinical interventions should target coping and conformity reasons for drinking among anxious, reward responsive, young adults.

RESUMO

Background and aims: Problem gambling and tobacco use are highly comorbid among adults. However, there are few treatment frameworks that target both gambling and tobacco use simultaneously (i.e., an integrated approach), while also being accessible and evidence-based. The aim of this two-arm open label RCT was to examine the efficacy of an integrated online treatment for problem gambling and tobacco use. Methods: A sample of 209 participants (Mage = 37.66, SD = 13.81; 62.2% female) from North America were randomized into one of two treatment conditions (integrated [n = 91] or gambling only [n = 118]) that lasted for eight weeks and consisted of seven online modules. Participants completed assessments at baseline, after treatment completion, and at 24-week follow-up. Results: While a priori planned generalized linear mixed models showed no condition differences on primary (gambling days, money spent, time spent) and secondary outcomes, both conditions did appear to significantly reduce problem gambling and smoking behaviours over time. Post hoc analyses showed that reductions in smoking and gambling craving were correlated with reductions in days spent gambling, as well as with gambling disorder symptoms. Relatively high (versus low) nicotine replacement therapy use was associated with greater reductions in gambling behaviours in the integrated treatment condition. Discussion and conclusions: While our open label RCT does not support a clear benefit of integrated treatment, findings suggest that changes in smoking and gambling were correlated over time, regardless of treatment condition, suggesting that more research on mechanisms of smoking outcomes in the context of gambling treatment may be relevant.

RESUMO

We extracted items to create a brief version of the COVID-19 Stress Scale (i.e., CSS-B) and examined its psychometric properties in young adults. A sample of 1318 first- and second-year undergraduates from five Canadian universities (mean [SD] age = 19.27 [1.35] years; 77.6% women) completed an online cross-sectional survey that included the CSS-B as well as validated measures of anxiety and depression. The 18-item CSS-B fit well on both a 5-factor and a hierarchical model indicating that the five CSS-B dimensions may be factors of the same over-arching construct. The CSS-B factor structure displayed lower-order and higher-order configural and metric invariance across sites but not scalar invariance indicating that the intercepts/means were not consistent across sites. The CSS dimensions were positively related to measures of general anxiety and depression but not so strongly as to indicate that they are measuring the same construct. The CSS-B scale is a valid measure of COVID-19 stress among young adults. It is recommended that this shorter version of the scale be considered for use in longer surveys to avoid participant fatigue.

RESUMO

Emerging adults with high levels of inhibited personality traits may be at-risk for drinking to cope during the COVID-19 pandemic. The current research explored mediational pathways between two inhibited personality traits (anxiety sensitivity (AS) and hopelessness (HOP)), internalizing symptoms (anxiety, depression, and COVID-19 distress), and coping drinking motives (drinking to cope with anxiety and drinking to cope with depression) during the pandemic. Cross-sectional data were collected from 879 undergraduate drinkers (79% female, 83% White, 18-25 years old) at five Canadian universities from January-April 2021. Participants self-reported on their personality, anxiety (GAD-7), depressive symptoms (PHQ-9), COVID-19 distress, and coping drinking motives. Mediational path analyses provided evidence of both specific and non-specific pathways between personality and coping motives via internalizing symptoms. Depressive symptoms partially mediated the link between HOP and drinking to cope with depression motives. While anxiety symptoms did not significantly mediate links between AS and coping with anxiety motives in the full model, evidence of mediation was found in a post-hoc sensitivity analysis. COVID-19 distress served as a non-specific mediator. AS and HOP are critical transdiagnostic risk factors that increase vulnerability for internalizing psychopathology and, in turn, risky drinking motives, in the context of the COVID-19 pandemic.

RESUMO

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.

RESUMO

Using a multigroup path analysis, we examined if hazardous alcohol use mediated the relations between elevated externalizing personality traits (i.e., impulsivity or sensation seeking) and reduced adherence to COVID-19 public health guidelines. We hypothesized that those high in externalizing personality traits would demonstrate less adherence to public health guidelines and that hazardous alcohol use would mediate this relationship. First- and second-year undergraduates (N = 1232; ages 18-25) from five Canadian universities participated in a cross-sectional survey between January to April 2021. Individuals with higher levels of impulsive or sensation seeking personality traits demonstrated poorer adherence to COVID-19 public health guidelines and these relations were mediated by hazardous alcohol use. Results suggest that hazardous drinking is an important target for students high in impulsivity and sensation seeking to increase their adherence to public health guidelines and thereby help control viral spread.
