A Rebuttal-Based Social Norms-Tailored Cannabis Intervention for At-Risk Adolescents

Can we predict adolescent cannabis use? A Bayesian semi-parametric approach to project future trends

Despite its decrease in many Western countries, cannabis remains the most used illicit substance among adolescents. This study aims to summarize cannabis consumption during the last two decades and project trends among 15-year-olds in the 2021-22 HBSC survey. A Bayesian semi-parametric hierarchical model was adopted to estimate the trend of cannabis consumption using data of about 287,000 adolescents from the 2001/2002 to the 2017/2018 HBSC wave and the 38 countries that met the inclusion criteria. Data show an overall decline in most countries for both boys and girls. However, in 22 countries of 38 cannabis use is expected to increase again in our projection. The discussion of these findings should take into account cultural, policy, social factors and unpredictable events such as the Covid-19 pandemic, that can significantly impact future trends leading to discrepancies between the projected and observed values. However, these discrepancies can provide insight into understanding the potential impact of preventive strategies and the underlying processes responsible for changes in cannabis use over time.

Psychological reactance and adolescent cannabis use: The role of parental warmth and monitoring

Psychological reactance (PR) is a psychological state or trait typified by resistant responses to threats to behavioral freedom. PR has been linked with negative health behaviors, including risky substance use; however, factors that may foster approaches to mitigate the impact of PR on these behaviors, as well as rejection of other health promotion communications is less understood. The current studies examined relations between parental warmth and monitoring with trait PR and responses to preventive cannabis communications and usage intentions. Two in-school surveys were administered to two difference samples of middle school students (Study 1, N = 1,416; Study 2, N = 1,118). Path analytic models tested multivariable linkages among relevant parenting variables, PR, and outcomes associated with cannabis use. Follow-up regression analyses explored significant interaction effects. In Study 1 (p <0.001) and Study 2 (p <0.01), parental warmth moderated the relation between monitoring and trait PR: High monitoring was a protective factor only when combined with high warmth. In turn, PR mediated the relationships between parenting practices and cannabis intentions in both studies (p <0.001). In Study 2, PR also was linked with resistance to persuasion via more unfavorable reactions to anti-cannabis appeals (p <0.001). Findings indicated that low parental warmth combined with high parental monitoring was associated with high trait reactance in adolescents, which predisposed them to stronger resistance to preventive communications. Interventions might focus on counseling parents about the likely outcomes of parenting style, and ways to implement beneficial approaches.

Application of behavioral economics for understanding health behaviors among adolescents and young adults

PURPOSE OF REVIEW

Behavioral economics (BE) concepts have become well studied tools in addressing patient issues, such as weight loss, smoking cessation, and medication adherence. Although predominantly studied in adult populations, emerging literature has shown BE's utility for adolescent/young adult (AYA) populations, offering a practical framework to safeguard AYA health and influence healthy decision making.

RECENT FINDINGS

We identified substantive areas in which BE concepts have been applied in AYA populations (e.g., substance use) and outline how these concepts have been used as a tool to identify individuals at risk for poor outcomes and to leverage behavioral insights to improve health behaviors.

SUMMARY

BE research holds significant promise as a tool for clinicians and researchers to encourage healthy decision making in AYA populations. Yet, there are opportunities for BE research to expand further into current trends impacting adolescent health, such as electronic nicotine delivery systems, social media apps, and coronavirus disease 2019 vaccinations. Furthermore, the full degree of BE utility remains to be explored, as few studies demonstrate the translation of associative findings into direct interventions. Additional work is needed to formalize BE techniques into best practices that clinicians can implement in their daily practice.
