Emotional Psychopathology and Coping Cannabis Use Motives Are Involved in the Link Between Anxiety Sensitivity and Adverse Cannabis-Related Outcomes in Canadian Emerging Adults
Background: Cannabis use and related problems are prevalent among Canadian emerging adults. Investigating risk factors for cannabis use and related problems, such as personality traits, is important for earlier risk mitigation in this vulnerable population. Anxiety sensitivity (AS) is associated with adverse cannabis outcomes in emerging adults, though the mechanisms driving this effect remain unclear. Theory linking AS to cannabis use and relate…
Easier Said Than Done
Background Experiential learning activities have demonstrated superior learning outcomes for students in addiction psychology courses. In this project, we asked students to select a behavior they would like to change and to actively work to reduce it throughout the semester. Students were asked to submit an assignment detailing their experiences with the behavior change process. Purpose We aimed to examine if this experiential learning activity w…
Emotion Dysregulation and E-Cigarette Use Among University Students
Nicotine vaping has risen sharply among emerging adults, emphasizing the need to clarify psychosocial factors underlying regular and problematic use. This study examined whether emotion dysregulation (ED) is associated with vaping among university students and whether descriptive norms (perceived peer use) and injunctive norms (perceived peer approval) account for indirect associations linking ED and vaping. Canadian undergraduates ( N = 723; M a…
Development and Evaluation of the Psychometric Properties of the Modified College Eating and Cannabis Behaviors Scale (CECBS)
Evaluating the Compulsive Buying Scale in a Canadian non-clinical sample
Distress-prone personality traits, mental well-being, and academic engagement among emerging adults across five Canadian universities
Relationship Between Personality Traits and Emotional Impacts of the Covid-19 Pandemic on Canadian Emerging Adults
We assessed whether traits from the four-factor vulnerability model for substance misuse are associated with the content of emotional descriptions given by Canadian university students of the impact of the COVID-19 pandemic on their lives. Personality traits were measured in 1185 first- and second-year undergraduates (mean age = 19.11 years; 79% female). Written responses to "Tell us about how the COVID-19 pandemic is impacting your life" were co…
Of College Students Who Engage in Non-Suicidal Self-injury Do Not Seek Treatment
Non-suicidal self-injury (NSSI) is a high-risk behavior, yet much remains unknown about NSSI treatment utilization. The current study seeks to determine cross-national endorsement rates of NSSI and NSSI treatment utilization among college students. The present study uses baseline data from a survey study of 4,772 college students who completed a measure of NSSI recruited from the USA, Canada, Spain, South Africa, Argentina, and England. In total,…
Sensation seeking, impulsivity, Covid-19 stress, and drinking among emerging adults
Impulsivity and sensation seeking linked to COVID-era alcohol use. • Distinct COVID stressors mediate risk and protective drinking pathways. • Sensation seeking tied to lower fear, higher drinking during pandemic. • Impulsive traits predict both trauma-linked and fear-reducing outcomes. • Supports personality-targeted interventions for emerging adults. This study examined relations between sensation seeking, impulsivity, COVID-related stress and …
Emotional difficulties mediate the impact of adverse childhood experiences on compulsive buying-shopping problems
Indirect Associations Between PTSD Symptoms and Cannabis Problems in Young Adults
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 ou…
Examining the psychometric properties of the electronic gaming motives questionnaire in a sample of Canadian adults
Longitudinal co-trajectories of depression and alcohol problems in adults during the Covid-19 pandemic
Individualism, collectivism, and emotion regulation
Individualism and collectivism are dimensions of cultural variation thought to shape differences in emotion regulation tendencies, yet research to date has examined these cultural dimensions as country-level features, emphasizing variability across nations. The present study takes the approach of examining cultural differences within nations as predictors of emotion regulation strategies, shifting the perspective instead to individual differences…
Cross-national examination of the Distress Tolerance Scale using Rasch methodology
The 15-item Distress Tolerance Scale (DTS) is a widely used psychometric measure with evidence generally supporting its reliability and validity. However, limitations related to its ordinal response format and lack of cross-cultural comparisons have yet to be investigated using appropriate methods. The Partial Credit Rasch model was used to evaluate and enhance the psychometric properties of the DTS using responses from 2550 adult participants fr…
Internalizing personality traits and coping motivations for gaming during the Covid-19 pandemic
Anxiety sensitivity and hopelessness are two traits that have been previously linked to increased gaming problems. Research in the early stages of the COVID-19 pandemic showed that emotionally vulnerable individuals were turning to video games as a means of coping with their distress. However, more research is needed on the long-term and enduring pathways from internalizing traits to time spent gaming during COVID-19, after the lockdowns and prev…
When Chilling Out Casts Doubt
Research shows that both cannabis use and emotional problems (anxiety and depression) tend to peak in emerging adulthood. There is a relative paucity of research examining the temporal associations between cannabis use and emotional problems among emerging adults. Accordingly, this multi-wave longitudinal study examined three competing models of temporal precedence: the vulnerability model (negative emotions precede cannabis use); the scar model …
Personality Traits and Links between Bullying, Emotional Distress, and Substance Use among Emerging Adults
Demographic, Mental Health, and Substance Use Correlates of Self-Described Medicinal Use, Recreational Use, and Non-Use of Hallucinogenic Drugs
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 communicat…

Coping and Conformity Motives Mediate the Joint Effects of the Behavioral Inhibition and Approach Systems on Alcohol Problems in Young Adults
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…
Utility of the Brief Young Adult Alcohol Consequences Questionnaire to Identify College Students At-Risk for Alcohol Related Problems
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 AU…

Identifying and Predicting Multiple Trajectories of Alcohol Dependence Symptoms in a Canadian Sample of Emerging Adults
Working with data from the Manitoba Longitudinal Study of Young Adults (four cycles over 4 years; mean baseline age of 18.9 years), this study used latent class growth analysis to identify four alcohol dependence trajectory classes—low, decreasing (nondependence); high, decreasing (developmentally limited); low, increasing (adult onset); and persistently class were also identified: Being male, illicit drug use, stressful life events, impulsivity,…
Examining gambling activity subtypes over time in a large sample of young adults
Background: Gambling is common in young adulthood. Most young adults phase out of excessive gambling, but some establish regular habits and develop problems. Research has begun to examine the risk associated with different gambling activity patterns. However, there is a paucity of longitudinal work. Using a prospective design, we identified distinct subgroups of young adults based on patterns of gambling activity involvement and tested the stabil…
Drinking to Cope During Covid‐19 Pandemic
BACKGROUND: The COVID-19 pandemic has resulted in massive disruptions to society, to the economy, and to daily life. Some people may turn to alcohol to cope with stress during the pandemic, which may put them at risk for heavy drinking and alcohol-related harms. Research is needed to identify factors that are relevant for coping-motivated drinking during these extraordinary circumstances to inform interventions. This study provides an empirical e…
Exploring Differences Among Video Gamers With and Without Depression
Video games are a leisure activity with mass appeal for individuals of all ages. However, for some individuals, playing video games may become problematic and addictive, resulting in negative consequences affecting their physical, social, and psychological well-being. Internet gaming disorder (IGD) has estimated prevalence rates of around 3 percent and has been strongly associated with several psychopathologies, including depression. Given that e…
Depression, Environmental Reward, Coping Motives and Alcohol Consumption During the Covid-19 Pandemic
Background: Increases in the incidence of psychological distress and alcohol use during the COVID-19 pandemic have been predicted. Behavioral theories of depression and alcohol self-medication theories suggest that greater social/environmental constraints and increased psychological distress during COVID-19 could result in increases in depression and drinking to cope with negative affect. The current study had two goals: (1) to examine self-repor…

Shame’s Associations with Depression and Problem Drinking
INTRODUCTION: Depression and problem drinking are comorbid in emerging adulthood, yet the processes that link them are not well understood. Research has argued that shame has a unique influence on the experience of problematic drinking, but this has rarely been assessed at the state level. Using ecological momentary assessments (EMAs), we assessed whether shame, and not guilt, mediated the association between baseline depression and alcohol use a…
Coping with Shame Mediates the Association Between Depression and Gambling Severity and Frequency
Examining Subtypes of Emerging Adult Situational Drinking
Background: Emerging adulthood is associated with heavy drinking. Despite overall heavy use, studies show considerable heterogeneity in emerging adult drinking habits. Lau-Barraco and colleagues (2016 b) identified three subtypes (high, moderate, low) of emerging adult heavy drinkers based on patterns of use across common drinking situations. Heavy situational drinkers had more alcohol problems, mental health symptoms, and coping/conformity motiv…
Measuring Impaired Control over Cannabis Use
Background: Impaired control is a central concept in addiction. Impaired control over alcohol has been associated with heavy drinking and alcohol-related problems in young adults, but there is less research on impaired control over cannabis. Currently, there is no validated self-report instrument that comprehensively assesses impaired control over cannabis use. This study examined the factor structure, reliability, and validity of a new measure, …
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. 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 s…
Drinking Motives as Mediators of the Relationship of Cultural Orientation with Alcohol Use and Alcohol-Related Negative Consequences in College Students from Seven Countries
Loot box purchasing is associated with gambling and problem gambling when controlling for known psychological risk factors of gambling
Background A robust literature has found that loot box purchasing is associated with gambling and problem gambling. However, it remains unclear whether this association is merely an artifact of known psychological risk factors for gambling. The present study thus examined associations of loot box purchasing with gambling and problem gambling while controlling for potential psychological confounders.Methods Current gamers, recruited from five Cana…

Adverse childhood experiences and adulthood mental health
Gaming as a coping strategy during the Covid-19 pandemic
Early in the COVID-19 pandemic, social interactions were constrained by physical distancing guidelines. Consequently, some individuals may have turned to video games to cope with isolation and negative emotions. Previous studies have shown that people who struggle with anxiety and depression are at particular risk for developing problem gaming behaviours. However, there is a paucity of longitudinal research testing pathways from negative emotiona…
