High peak drinking levels mediate the relation between impulsive personality and injury risk in emerging adults

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.

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 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.

Psychometric properties of a brief version of the COVID‐19 Stress Scales (CSS‐B) in young adult undergraduates

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.

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. 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.

When and How Do Brief Alcohol Interventions in Primary Care Reduce Alcohol Use and Alcohol-Related Consequences among Adolescents?

OBJECTIVE

To systematically describe when and how brief alcohol interventions delivered to adolescents in primary care settings reduce alcohol use and alcohol-related consequences among adolescents, using realist review methodology.

STUDY DESIGN

Eleven electronic databases, gray literature, and reference screening were searched up to June 2016; 11 brief interventions published in 13 studies met inclusion criteria. Intervention design components (delivery context and intervention mechanisms) underlying brief alcohol interventions for adolescents were extracted and linked to alcohol use and related consequences.

RESULTS

Brief interventions had either an indicated context of delivery (provided to adolescent patients with low-to-moderate risk for alcohol problems) or universal context of delivery (provided to general adolescent patient population). Interventions that used motivational interviewing in an indicated delivery context had 2 potential mechanisms-eliciting and strengthening motivation to change and providing direction through interpretation. These interventions resulted in clinically significant reductions in alcohol use and associated consequences. Peer risk also was identified among universal and indicated brief interventions as a potential mechanism for changing alcohol-related outcomes among adolescents who received the intervention. None of the studies tested the processes by which interventions were expected to work.

CONCLUSIONS

The current evidence base suggests that both indicated and universal delivery of brief alcohol interventions to adolescents in primary care settings can result in clinically important changes in alcohol-related outcomes. Studies that test brief intervention processes are now necessary to better understand how brief interventions work with adolescents in primary care settings.

The mediating role of alcohol-related memory associations on the relation between perceived parental drinking and the onset of adolescents' alcohol use

AIMS

The aim of the current study was to examine the mediating role of alcohol-related memory associations in the relation between perceived parental drinking and the onset of adolescents' alcohol use. Gender and grade were also included in the analyses.

DESIGN

We tested a mediation model within a structural path modelling framework using longitudinal data (two waves).

SETTING AND PARTICIPANTS

The sample consisted of 608 Canadian adolescents (42.9% boys), who did not have any alcohol experiences at the first measurement. The adolescents were recruited from all grades 7-9 classes in a large school district in western Canada.

MEASUREMENTS

Alcohol-related memory associations were tested with the Word Association Test. We used adolescent self-reports of alcohol use and parental drinking.

FINDINGS

Results clearly showed a mediation effect of alcohol-related memory associations [estimate = 0.023, 95% confidence interval (CI): 0.002-0.044). That is, parental drinking as perceived by the adolescent was related positively to alcohol-related memory associations, which in turn predicted adolescents' alcohol use a year later. Gender and grade were related to alcohol-related memory associations. That is, boys and adolescents of higher grades had more memory associations.

CONCLUSIONS

Children appear to form memory associations related to alcohol before they ever drink alcohol themselves, and these associations appear to mediate the link between their perceptions of their parents' drinking and their own initial alcohol use.

Strengthening the Canadian alcohol advertising regulatory system

Research evidence points to harmful effects from alcohol advertising among children and youth. In particular, exposure to alcohol advertising has been associated with adolescents drinking both earlier and heavier. Although current federal and provincial guidelines have addressed advertising practices to prevent underage drinking, practice has not been supported by existing policy. While protective measures such as social marketing campaigns have the potential for counteracting the effects from alcohol advertising, the effectiveness of such measures can be easily drowned out with increasing advertising activities from the alcohol industry, especially without effective regulation. Research reviewed by the European Focus on Alcohol Safe Environment (FASE) Project has identified a set of key elements that are necessary to make alcohol advertising policy measures effective at protecting children and youth from the harmful effects of alcohol marketing. Using these key elements as an evaluation framework, there are critical components in the Canadian alcohol advertising regulatory system that clearly require strengthening. To protect impressionable children and youth against the harmful effects of alcohol advertising, 13 recommendations to strengthen current alcohol advertising regulations in Canada are provided for Canadian policy-makers, advertising standard agencies, and public health groups.

Prevention education effects on fundamental memory processes

This study evaluated effects of a key session from a nationally recognized drug abuse prevention program on basic memory processes in 211 high-risk youth in Southern California. In a randomized, between-subject design, the authors manipulated assignment to a Myth and Denial program session and the time of assessment (immediate vs. 1-week delay). The authors examined program decay effects on memory accessibility and judgment errors. Those participants exposed to the program session generated more myths and facts from the program than those in the control group, suggesting that even a single program session influenced students' memory for program information and this was retained at least 1 week and detectable with indirect tests of memory accessibility. However, consistent with basic research perspectives, participants in the program-delayed assessment group erroneously generated more fact-related information from the session to the prompt "It is a myth that_____" than the participants in the program immediate assessment group; that is, they retained more facts as myths. These types of program effects, anticipated by basic memory theory, were not detected with a traditional judgment task in the present sample. The results suggest that basic science approaches offer a novel way of conceptually recasting prevention effects to more completely understand how these effects may operate. Implications for program evaluation and conceptualization are discussed.

Structural, concurrent, and predictive validity of the Substance Use Risk Profile Scale in early adolescence

A brief personality risk profile (23 items), the Substance Use Risk Profile Scale was tested for concurrent and predictive validity for substance use in 1139 adolescents (grades 8-10) from a mid-sized city in western Canada. The SURPS was administered in two waves of a longitudinal study separated by 12 months (2003-04). As expected, four subscales were supported by confirmatory factor and metric invariance analysis. In regression analysis, three subscales, hopelessness, impulsivity, and sensation seeking, were positively related to current and future use; while one, anxiety sensitivity, was negatively related. Findings suggest clinical utility for screening adolescents at risk for substance use.

Impulsivity, impulsive and reflective processes and the development of alcohol use and misuse in adolescents and young adults

This paper contrasts dual-process and personality approaches in the prediction of addictive behaviors and related risk behaviors. In dual-process models, behavior is described as the joint outcome of qualitatively different “impulsive” (or associative) and “reflective” processes. There are important individual differences regarding both types of processes, and the relative strength of both in a specific situation is influenced by prior behavior and state variables (e.g., fatigue, alcohol use). From this perspective, a specific behavior (e.g., alcohol misuse) can be predicted by the combined indices of the behavior-related impulsive processes (e.g., associations with alcohol), and reflective processes, including the ability to refrain from a motivationally salient action. Personality approaches have reported that general traits such as impulsivity predict addictive behaviors. Here we contrast these two approaches, with supplementary analyses on four datasets. We hypothesized that trait impulsivity can predict specific risky behaviors, but that its predictive power disappears once specific behavior-related associations, indicators of executive functioning, and their interaction are entered into the equation. In all four studies the observed interaction between specific associations and executive control (EC) was robust: trait impulsivity did not diminish the prediction of alcohol use by the interaction. Trait impulsivity was not always related to alcohol use, and when it was, the predictive power disappeared after entering the interaction between behavior-specific associations and EC in one study, but not in the other. These findings are interpreted in relation to the validity of the measurements used, which leads to a more refined hypothesis.

Context Effects on Alcohol Cognitions

This article summarizes a symposium on context and alcohol-related cognitions presented at the 2004 Annual Meeting of the Research Society on Alcoholism in Vancouver, British Columbia, Canada. The studies reported here examine how the manipulation of contextual variables influences the availability of alcohol outcome expectancies and implicit memories for alcohol associations. The symposium illustrates the range of context variables and shows some of the potential impact of retrieval on cognitions that predict alcohol use. Two of the studies explore naturalistic drinking contexts: one examines the impact of stress induction, and one assesses within survey question placement effects. A variety of measures of alcohol cognitions were used. The results demonstrate that alcohol cognitions are more accessible in alcohol-related contexts. Moreover, availability of alcohol associations and expectancies depended on individual differences. These results underscore the potential value of memory processes in the retrieval and measurement of alcohol cognitions. The findings have direct implications for improving methods of predicting alcohol use and in understanding the role of alcohol cognitions in various contexts associated with alcohol use.

New Developments in Prevention and Early Intervention for Alcohol Abuse in Youths

This article summarizes a symposium held at the 2004 Annual Meeting of the Research Society on Alcoholism in Vancouver, British Columbia, Canada. It was prepared by the conference co-organizers/co-chairs with substantial input from each of the symposium participants. Increasingly, alcohol abuse interventions focus on preventing alcohol problems or intervening early before risky drinking behavior becomes ingrained. Universal prevention programs have produced no or only modest effects on the drinking behavior of youths. Although some existing targeted prevention programs have proved effective, they have not tapped the full range of potential intervention targets, such as the underlying motivations for alcohol misuse in youths who are at greatest risk. The set of papers presented in this symposium outline exciting new developments in the field of targeted prevention and early intervention programs for adolescent drinking problems, presented by an international panel of researchers. These developments include attention to making interventions relevant to adolescents' lives, focus on personality and motivational factors underlying alcohol misuse, and combining existing cognitive behavioral programs with expectancy challenge and motivational interviewing techniques.

Implicit and explicit alcohol-related cognitions

This article presents the proceedings of a symposium at the 2001 RSA Meeting in Montreal, Canada organized by Reinout W. Wiers and Alan W. Stacy. The purpose of the symposium was to present recent applications of implicit cognitive processing theory to alcohol research. Basic cognitive research has demonstrated that implicit cognition influences memory and behavior without explicit recall or introspection. The presentations from this symposium show that implicit cognition approaches yield new insights into understanding drinking motivation. The presentations were: (1) An introduction by Alan W. Stacy; (2) Implicit cognition and alcohol use. Involvement of other variables? (Susan L. Ames); (3) Alcohol expectancies and the art of implicit priming (Jane A. Noll); (4) Parental alcoholism and the effects of alcohol on semantic priming (Michael A. Sayette); (5) Implicit arousal and explicit liking of alcohol in heavy drinkers (Reinout W. Wiers); and (6) Negative affective cues and associative cognition in problem drinkers (Martin Zack). Comments were provided by the discussant Marvin Krank. The presented studies demonstrated that: (1) implicit memories of alcohol associations are powerful predictors and cross-sectional correlates of alcohol use; (2) implicit retrieval processes influence alcohol outcome expectancies and alcohol consumption; (3) alcohol consumption influences implicit memory processing; (4) heavy drinkers reveal different affective responses in implicit and explicit tasks; and (5) negative affect exerts an implicit priming effect for alcohol associations in problem drinkers. These findings illustrate the importance of implicit cognition in understanding alcohol abuse and demonstrate the potential of the theoretical framework for more widespread application across a variety of areas of alcohol research, including diagnostics for the risk of alcohol abuse, treatment, and prevention.
