Psychometric properties and Longitudinal Measurement Invariance of the Spanish version of the Alcohol Expectancies Questionnaire Short Form among young adult binge drinkers. THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2024:1-12. [PMID: 39159464 DOI: 10.1080/00952990.2024.2377256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 06/04/2024] [Accepted: 06/22/2024] [Indexed: 08/21/2024]
Abstract
Background: Longitudinal Measurement Invariance (LMI) is critically important to evaluate changes in alcohol expectancies over time. However, past research has not explored the longitudinal properties of the Spanish Expectancy Questionnaire Short Form (EQ-SF).Objectives: To examine the reliability, sources of validity (structural, invariance across sex, and concurrent validity), and LMI of the Spanish EQ-SF among young adults who engage in binge drinking.Methods: Participants (n = 279; 48.4% female) completed the EQ-SF and, two months later, completed it again along with measures of alcohol use, drinking motives, and protective behavioral strategies (PBS). We performed confirmatory factor analysis for structural validity and measurement invariance analysis for longitudinal and sex stability.Results: The eight-factor intercorrelated model (i.e. social facilitation, fun, sexual disinhibition, tension reduction, antisocial effects, negative emotional states, negative physical effects, and cognitive impairments) provided the best fit (χ2(df) = 497.29(224), CFI = .962, RMSEA = .064, SRMR = .049). This model was invariant across sex and time. Reliability coefficients (Ordinal alpha) for each dimension were consistently strong at both time points (from .72 to .93 at T1 and .73 to .91 at T2). Positive alcohol expectancies at baseline were positively related to alcohol use and drinking motives and negatively related to PBS at follow-up, demonstrating predictive validity.Conclusion: Our results support the temporal invariance of the EQ-SF scores among Spanish young adults who engage in binge drinking. The evidence supports the suitability of this measure for accurately assessing changes in alcohol expectancies over time in interventions aimed at preventing binge drinking in young adults.

Trends in the co-occurrence of substance use and mental health symptomatology in a national sample of US post-secondary students from 2009 to 2019. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2024; 72:1911-1924. [PMID: 35834773 DOI: 10.1080/07448481.2022.2098030] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 05/20/2022] [Accepted: 06/27/2022] [Indexed: 05/18/2023]
Abstract
Objective: This study examined joint trends over time in associations between substance use (heavy drinking, cannabis, and cigarette smoking) and mental health concerns (depression, anxiety, and suicidal ideation) among US post-secondary students. Participants: Data came from 323,896 students participating in the Healthy Minds Study from 2009 to 2019, a national cross-sectional survey of US post-secondary students. Weighted two-level logistic regression models with a time by substance interaction term were used to predict mental health status. Results: Use of each substance was associated with a greater odds of students endorsing depression, anxiety, and suicidal ideation. Over time, the association with mental health concerns strengthened substantially for cannabis, modestly for heavy drinking, and remained stable for smoking. Conclusion: Given co-occurrence is common and increasing among post-secondary students, college and university health systems should prioritize early identification, psychoeducation, harm-reduction, and brief interventions to support students at risk.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024:104514. [PMID: 39030084 DOI: 10.1016/j.drugpo.2024.104514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 06/25/2024] [Accepted: 06/28/2024] [Indexed: 07/21/2024]
Abstract
The concept of harm reduction was a radical departure from a century of stigmatizing demand reduction initiatives targeted at people who use drugs. In fact, since the early 1980's Harm Reduction has been used with great success to protect the lives and wellbeing of these individuals. When employed with people who use opioids, the relevancy and importance of harm reduction are easy to grasp because the potential dangers are both quite visible and profound. However, promoting harm reduction practices to people consuming cannabis is a more difficult challenge. Cannabis cannot cause death due to overconsumption, is not associated with the spread of communicable diseases, and is overall a relatively harmless drug both to the individual and society when compared with other legal substances such as tobacco and alcohol. Harm reduction campaigns targeted at cannabis consumers run the risk of sounding overly fearful and stigmatizing, ultimately being ignored like many of the old demand reduction initiatives. Cannabis does have potential harms, and teaching people to mitigate those harms is an important public health goal. This commentary argues that cannabis education targeted at young people should employ mindful consumption and benefit maximization (MCBM) language that promotes harm reduction practices but does not focus on harm as the primary issue related to cannabis use. We define what we mean by mindful consumption and benefit maximization, identify their convergence with harm reduction principles, and argue for their use to both promote knowledge and normalize cannabis consumption that incorporates harm reduction practices.

Abstract
OBJECTIVE Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important. PARTICIPANTS AND METHODS A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk- and correlation-analysis was used to identify factors associated with problem-drinking and regular heavy-drinking. Independent t-tests compared impulsivity and personality traits, chi-square-tests compared drinking motives between risk- and non-risk-drinkers. RESULTS Male gender, tobacco-smoking, illegal substance use, impulsivity and various sociodemographic and psychosocial variables were significantly related to problem/heavy-drinking. Extraversion was a risk, conscientiousness and agreeableness were protective factors. Drinking-motives did not differ significantly between risk- and non-risk-drinkers. Generally, the main drinking-motives were to feel elated, relax and social purposes. CONCLUSION The identified markers and related problem behaviors may serve as a tool to enhance the identification of student subgroups at risk for problem/heavy-drinking, and hence improve targeted health-intervention-programs.

Abstract
Measures that seek to minimise the health and social consequences of substance use are an integral part of national drug strategies in many European countries. Against the backdrop of a high prevalence of cannabis use in the economically advanced countries, and increasing demand for treatment for cannabis-related problems, a range of harm reduction measures have been implemented by peers, statutory bodies and third-sector organisations. Based on a systematic review of the literature, the author describes these different forms of intervention, identifies innovative strategies and presents a simple typology that can be used when exploring existing measures or seeking to develop new policies. This typology covers different kinds of legal, socio-organisational and health-related interventions. All study designs were eligible for inclusion, with the exception of case reports, non-systematic reviews, editorials and news stories. Studies had to be published between 2011 and 2022, in English, and they had to refer to Europe, the Americas, Australia or New Zealand. A two-concept search was implemented using Embase.com and a number of other databases, combined with citation searches and manual website searching to improve coverage of research reports and advocacy documents. A total of 35 documents were deemed eligible, many of which rely on qualitative research methods.

Abstract
INTRODUCTION The high prevalence of cannabis use and the potential for negative effects indicate the need for effective prevention strategies and treatment of people who use cannabis. Studies show that harm reduction (HR) in cannabis use is effective in minimising the harmful consequences of the substance. However, health professionals often misunderstand it and resist its adoption due to various obstacles. To our knowledge, there has been no review of the scientific literature on the factors that facilitate or hinder practitioners' adoption of HR in cannabis use. To fill this gap, we aim to identify, through a scoping review, facilitators and barriers to healthcare providers' adoption of HR in cannabis use in Organisation for Economic Cooperation and Development (OECD) countries. METHODS AND ANALYSIS Our methodology will be guided by the six-step model initially proposed by Arksey and O'Malley (2005). The search strategy will be executed on different databases (Medline, PsycINFO, CINAHL, Web of Science, Embase, Sociological Abstracts, Érudit, BASE, Google Web and Google Scholar) and will cover articles published between 1990 and October 2022. Empirical studies published in French or English in an OECD country and identifying factors that facilitate or hinder healthcare providers' adoption of HR in cannabis use, will be included. Reference lists of the selected articles as well as relevant systematic reviews will be scanned to identify any missed publications by the electronic searches. ETHICS AND DISSEMINATION Ethics approval is not required. The results will be disseminated through various activities (eg, publication in peer-reviewed journals, conferences, webinars and knowledge translation activities). The results will also allow us to conduct a future study aiming to develop and implement a knowledge translation process among healthcare practitioners working with youth in Quebec in order to enhance their adoption of HR in cannabis use.

Abstract
Objective To examine the correlates between cannabis use, motives to use, related psychosocial outcomes and academic behaviours among a sample of Canadian university students. Methods A random sample of 6,000 students who were enrolled in at least one class and were 18 years or over were asked to complete a cross-sectional online survey. Of the 920 students that responded, 478 (ages 18-55; mean age = 25.02, SD = 5.95) identified as having used cannabis within the past six months and thus were included as participants in the current study. Participants completed a battery of measures designed to examine cannabis use and associated constructs (i.e., substance use risk, personal well-being, non-specific psychological distress, academic behaviours, and motivations for use). Results Among the participants, 31% (n = 148) were found to be frequent (i.e., hazardous) users. Using cannabis for enhancement, coping, expansion, sleep difficulties, and conformity purposes, as well as impulsive personality traits were found to be predictors of cannabis use severity, with the enhancement motive identified as the strongest predictor for the total sample, males, and hazardous users. The coping motive was the strongest predictor for females, and impulsivity was the strongest predictor for non-hazardous users. Conclusion Findings will help inform the development of campus guidelines for lower risk cannabis use. Information gleaned from this study will also provide important information for those that use cannabis, policymakers, and health care providers in considering optimal personal use, prevention, and intervention plans.

Addict Behav 2023; 146:107789.

Abstract
Concurrent use of alcohol and cannabis among college students is common and confers greater harms than the use of either of these substances alone. Large and growing bodies of literature have demonstrated the independent utility of behaviors used before, during, after, or instead of alcohol and cannabis use that minimize related harms (i.e., protective behavioral strategies [PBS]). However, little is known about the relationship between alcohol and cannabis PBS and their joint influence on harms among college students who concurrently use alcohol and cannabis. In the present study, we used data from two large, multi-site samples of college students, and restricted analyses to those who reported at least one episode of alcohol and cannabis use in the past 30 days (Study 1: N = 1104[Mage = 20.3, SD = 3.8; 70.0 % female; 79.5 % white]; Study 2: N = 2034[Mage = 20.2, SD = 3.2; 69.1 % female; 76.6 % white]). A latent profile analysis supported a 4-profile solution that was largely consistent across samples: Profile 1 (low alcohol/cannabis PBS; 8.8-11.9 %), Profile 2 (average alcohol/cannabis PBS; 33.1-37.7 %), Profile 3 (average alcohol PBS/low cannabis PBS; 16.3-25.2 %), and Profile 4 (high alcohol/cannabis PBS; 29.8-37.2 %). Profile 4 reported the least alcohol/cannabis use, fewest negative alcohol-/cannabis-related consequences, and lowest alcohol/cannabis use severity. In contrast, Profile 1 was the opposite for alcohol-related outcomes, and Profile 3 was the opposite for cannabis-related outcomes. These findings are preliminary but may suggest that targeting both alcohol and cannabis PBS in intervention is generally beneficial except some groups at risk for a particular substance may benefit from increased focus on that substance in intervention.
