Expressive Writing About One's Trauma Increases Accessibility of Cannabis Information in Memory Among Trauma-Exposed Individuals.

Objective: Trauma survivors are more likely than others to use cannabis, and post-traumatic stress disorder (PTSD) commonly co-occurs with cannabis use disorder (CUD). Automatic memory associations between trauma reminders and cannabis use have been suggested as contributing mechanisms. These associations can be studied experimentally by manipulating trauma cue exposure in a cue-reactivity paradigm (CRP) and examining effects on the accessibility of cannabis information in memory in trauma survivors with and without PTSD.

Mental Health and Dispositional Predictors of Simultaneous Versus Concurrent Cannabis and Alcohol Use in a Canadian Context.

Objective: Cannabis has become more available in Canada since its legalization in 2018. Many individuals who use cannabis also use alcohol (co-use), which can be used either at the same time such that their effects overlap (simultaneous use) or at different times (concurrent use). Though studies have identified predictors of co-use relative to single-substance use, less is known about the predictors of specific types of co-use.

Negative urgency increases risk for coping-motivated cannabis outcomes in socially anxious male emerging adult cannabis users.

Tension reduction theory suggests that socially anxious emerging adults use cannabis to cope with negative affect. However, the literature is mixed, indicating that the effect of social anxiety on cannabis use behaviors during emerging adulthood may depend on other moderating factors, such as negative urgency. This study aimed to clarify potential moderators that may strengthen the associations between social anxiety and cannabis outcomes among emerging adults.

Associations of self-regulation strategy use with in-play betting intensity and associated harms: An ecological momentary assessment study.

Self-regulation strategies, such as limit setting, can be effective in reducing harms associated with gambling. However, limited research has examined their applicability to in-play sports betting. The current study therefore examined the utility of self-regulation strategies in reducing in-play betting intensity and associated harms.

Emotional difficulties mediate the impact of adverse childhood experiences on compulsive buying-shopping problems.

Background: Compulsive buying-shopping is recognised as a significant mental health concern, yet its aetiology is largely understudied. A known risk factor for compulsive buying-shopping is adverse childhood experiences (ACEs). ACEs are also associated with greater problems regulating emotions, as well as depression and anxiety.

Adverse Childhood Experiences and Problematic Cannabis Use: The Role of Emotion Dysregulation and Affective Impulsivity.

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.

Indirect Associations Between PTSD Symptoms and Cannabis Problems in Young Adults: The Unique Roles of Cannabis Coping Motives and Medicinal Use Orientation.

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.

Psychometric Validation of the Gambling Craving Scale in a Treatment-Seeking Sample.

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.

Internet-delivered therapy for alcohol misuse: engagement, satisfaction, and outcomes when patients select their preference for therapist- or self-guided treatment.

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.

Hazardous Drinking Mediates the Relation Between Externalizing Personality and Reduced Adherence to COVID-19 Public Health Guidelines in University Students.

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.

Do anxiety symptoms and coping motives serially mediate the association between psychotic-like experiences and cannabis-related problems in undergraduate recent cannabis users?

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).

Cannabis use and social anxiety disorder in emerging adulthood: Results from a nationally representative sample.

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.

The impact of cultural identity, parental communication, and peer influence on substance use among Indigenous youth in Canada.

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.

Effectiveness of a web-based self-help tool to reduce problem gambling: A randomized controlled trial.

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.

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.

Impulsivity Moderates the Association Between Anxiety and Problem Gambling Among Canadian Undergraduates.

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.

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).

Efficacy of a novel online integrated treatment for problem gambling and tobacco smoking: Results of a randomized controlled trial.

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.

Coping and Conformity Motives Mediate the Joint Effects of the Behavioral Inhibition and Approach Systems on Alcohol Problems in Young Adults.

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.

Longitudinal co-trajectories of depression and alcohol problems in adults during the COVID-19 pandemic.

Unlabelled: We examined person-centered heterogeneity in the longitudinal co-development of depression and alcohol problems during the COVID-19 outbreak. We also investigated the risk factors (personality and coping) for being in "higher" relative to "lower" risk subgroups of combined depressive symptoms and alcohol problems. Canadian participants ( = 364,  = 32.

Inhibited personality traits, internalizing symptoms, and drinking to cope during the COVID-19 pandemic among emerging adults.

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.

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.

Optimizing internet-delivered cognitive behaviour therapy for alcohol misuse-a randomized factorial trial examining effects of a pre-treatment assessment interview and guidance.

Background: Internet-delivered cognitive behavioral therapy (ICBT) for alcohol misuse has potential to radically improve access to evidence-based care, and there is a need to investigate ways to optimize its delivery in clinical settings. Guidance from a clinician has previously been shown to improve drinking outcomes in ICBT, and some studies suggest that pre-treatment assessments may contribute in initiating early change. The objective of this study was to investigate the added and combined effects of a pre-treatment assessment interview and guidance on the outcomes of ICBT for alcohol misuse delivered in an online therapy clinic.

Examining differential responses to the trial: A latent class and moderation analysis.

Given prevalent alcohol misuse-emotional comorbidities among young adults, we developed an internet-based integrated treatment called . Although the treatment had an impact on several secondary outcomes, effects were not observed for the primary outcome. Therefore, the goal of the current study was to examine heterogeneity in treatment responses.
