Alcohol and other substance use in a cross-cultural perspective

Prevalence and Predictors of Alcohol Use among School-Going Adolescents in Panama: A Population-Based Cross-Sectional Study

This study investigated the prevalence and predictors of alcohol use among school-going-age adolescents in Panama. Using a national school-based cross-sectional survey, data from a proportionate sample of school-going adolescents aged 13-17 years were obtained from the 2018 Panama Global School-based Student Health Survey [GSHS]. Data were analysed with a Pearson's Chi-square test and weighted binary logistic regression. The results were reported with their corresponding adjusted odds ratio (AOR) at a 95% confidence interval (CI) and level of significance set at p < 0.05. The prevalence of alcohol use among adolescents in Panama was 30.6%. The odds of alcohol use were lower among adolescents in a lower grade than those in upper grades, and lower in those who did not eat from a restaurant than those who ate from a restaurant. Further, the likelihood of alcohol use was significantly high among those who engaged in physical fights, were seriously injured, were mostly worried, and whose parents used any form of tobacco. Other results showed that the odds of alcohol use were high among sedentary respondents, those who had multiple sexual partners and those who used amphetamines. Based on the present findings, a collaborative approach (i.e., stakeholders- the Ministry of Social Development and the Ministry of Education- community-individual levels) towards the development and adherence of appropriate interventions aimed at reducing alcohol use is required in Panama. Specific preventive interventions would be fundamental in promoting a positive school climate to help reduce adolescents' alcohol use and, perhaps, other anti-social behaviours (e.g., physical fights and bullying).

Examining Cross-Country and Sex Differences on a Comprehensive Assessment of Protective Behavioral Strategies for Alcohol

OBJECTIVE

Use of protective behavioral strategies (PBS) has been associated with reduced alcohol-related harms among college students. However, most of this research has been conducted among U.S. samples. The present study examines the use of PBS in an international context.

METHOD

Participants (n = 1512) were recruited from universities in Spain (n = 298), Argentina (n = 439), and the U.S. (n = 775) to determine if there are differences in PBS use across countries and/or across sex. Further, we examined whether the association between PBS use and negative consequences differ across country and sex.

RESULTS

We found that U.S. students reported the most frequent use of Stopping/Limiting Drinking PBS (M = 3.32, SD = 1.23) compared to Argentine (M = 2.89, SD = 0.97) and Spanish (M = 2.83, SD = 0.94) students. Argentine students reported the least frequent use of Serious Harm Reduction PBS (M = 4.57, SD = 0.99) compared to U.S. (M = 5.09, SD = 0.98) and Spanish (M = 5.03, SD = 0.78) students. Elastic net regression analyses stratified by country indicated most individual PBS predicted decreased negative alcohol-related consequences, although two items consistently predicted increased consequences and we observed some variability in the most predictive specific strategies in each country. Across each subscale and for 32 of 40 individual items, females reported more frequent use of PBS than males (ps<.05).

CONCLUSIONS

From the perspective of developing and adapting interventions, we recommend the cultural context in which PBS are used is taken into account. Although future work is needed to delineate cultural factors underlying the country-level differences we found, these findings have implications for the most promising PBS to target for college students in each country.

A comparison of cannabis protective behavioral strategies use across cultures and sex

BACKGROUND

Cannabis protective behavioral strategies (PBS) are behaviors used before, during, after, and/or instead of cannabis use to reduce consumption, intoxication, and related harms. To leverage PBS to address the global health burden of cannabis use, especially in light of the changes in cannabis-related policies around the world, a better understanding of PBS across cultures is needed. In the present study, we conduct a cross-cultural examination of cannabis PBS use among college students.

METHOD

Participants were 1175 college students (U.S. [n = 697], Argentina [n = 153], Uruguay [n = 46], Spain [n = 169], and the Netherlands [n = 66]) who reported past-month cannabis use (63.3% female; M_age = 20.96, SD = 3.95).

RESULTS

We found differences in the frequency of cannabis PBS use across countries such that the U.S. and Spain samples reported the most frequent cannabis PBS use and the Netherlands sample reported the least frequent cannabis PBS use. Although not statistically significant, we found that cannabis PBS use was positively correlated with cannabis-related outcomes (i.e., frequency, quantity, and negative consequences of cannabis use) among the Argentina and the Netherlands samples. Finally, across all countries but the Netherlands, females reported more frequent cannabis PBS use than males, but the associations of PBS with cannabis-related outcomes were larger for males than females.

CONCLUSIONS

Given preliminary evidence for cultural differences in cannabis PBS use, future research is needed to better understand the cultural factors underlying these differences to inform the delivery of interventions aimed at reducing the harms of cannabis among college students.

Exploratory and confirmatory factor analysis of the parental rules toward adolescent drinking questionnaire: Two factors are better than the original one

The parental rules toward drinking questionnaire (PRQ; Van der Vorst et al., 2005) assesses strictness toward adolescent drinking situations. The aim of the current study was to address a gap in the literature on the psychometric testing and evaluation of the factor structure of the PRQ. The current sample consisted of Dutch adolescents (N = 2922) who participated in a randomized control trial with three intervention groups (parent, student, and parent + student) and a control. PRQ and frequency of alcohol use (past month and year) were measured at baseline (T1) and 12 months later (T2). Results from Exploratory and Confirmatory Factor Analyses revealed two reliable factors: (a) rules about normative drinking situations and (b) rules about non-normative drinking situations (both αs ≥ 0.88). Regression analyses conducted to examine the prospective effects of the interventions revealed that both parent conditions predicted increases in strictness toward normative drinking situations relative to the control condition, while only the parent + student condition affected the original PRQ (single factor). Further, the normative subscale predicted increases in drinking (past month and year), as did the original PRQ. Significant effects with the normative subscale indicate that rules toward these drinking situations are ones that account for the effects in the original PRQ, and that the original PRQ can mask effects. The results illustrate that the PRQ is multidimensional. The effects of the normative subscale suggest that intervention efforts should focus on preventing drinking situations that parents normally permit their adolescents to engage in.

Associations Between Peer Pressure and Adolescents' Binge Behaviors: The Role of Basic Needs and Coping

Framed from a framework based on the integration of self-determination theory (Ryan & Deci, 2000 ) and Endler and Parker's (1990) conception of coping strategies, the authors analyzed the relationships between peer pressure and binge behaviors (binge eating and binge drinking) in adolescence. Moreover, the authors explored the mediating role of satisfaction/frustration of basic psychological needs and coping strategies in these associations. Participants were 570 high school students (M = 15.75 years, SD = 1.14 years) living in Italy. The study design was cross-sectional and adolescents were administered self-report questionnaires. Path analysis showed significant and positive direct associations of peer pressure with both binge eating and binge drinking. Moreover, findings show that there is an indirect path in which peer pressure is positively associated with need frustration that is related to the use of emotion-oriented coping strategies that, on their turn, are associated with binge eating. Differently, binge drinking seems to be only directly related to peer pressure. The authors put light to the complex nature of the relationships between peer pressure and binge behaviors in adolescence, taking into account the separate contribution of need satisfaction and need frustration, as well as of coping strategies. Finally, practical implications of the study are discussed.
