Interpersonal Consequences Predicting Adolescent Substance Use: Examining the Role of Temptation Coping, Motivation, and Impulsivity.

Background: Adolescent substance use is highly prevalent and problematic; it has been reported as one of the most pertinent leading health concerns in the United States. The current longitudinal study examined the presence of peer and parental interpersonal relationship consequences (IP) as a motivating factor in activating coping skills to decrease the frequency of adolescent substance use, while further evaluating the role of impulsivity within that process. Objectives: Two main hypotheses were proposed: (1) IP will decrease substance use frequency mediated by increases in motivation and temptation coping; and (2) impulsivity will moderate the link between coping and substance use frequency. Participants included 343 adolescents between the ages of 13-19 (M = 16.23) referred to Project READY, a school-based substance use intervention. Assessments were completed during Sessions 1 and 4 of the intervention. Results: Serial mediation analyses indicated temptation coping, baseline alcohol use, and Time 2 marijuana use were the only statistically significant predictors of Time 2 alcohol use. Temptation coping and baseline marijuana use were the only statistically significant predictors of Time 2 marijuana use. Conclusions: Once adolescents' baseline and concurrent substance use were incorporated into the model, there was no statistical significance of the indirect effects. Results provided a stronger examination of the factors related to long-term substance use among adolescents. Knowing that temptation coping and baseline substance use levels were significant predictors of time 2 substance use independent of interpersonal consequences and motivation to change provides a structural frame and highlights need for early intervention.

The Effectiveness of a School-Based Intervention for Adolescents in Reducing Disparities in the Negative Consequences of Substance Use Among Ethnic Groups.

Ethnic minority youth are disproportionately affected by substance use-related consequences, which may be best understood through a social ecological lens. Differences in psychosocial consequences between ethnic majority and minority groups are likely due to underlying social and environmental factors. The current longitudinal study examined the outcomes of a school-based motivational enhancement treatment intervention in reducing disparities in substance use consequences experienced by some ethnic minority groups with both between and within-subjects differences. Students were referred to the intervention through school personnel and participated in a four-session intervention targeting alcohol and drug use. Participants included 122 youth aged 13-19 years. Participants were grouped by ethnicity and likelihood of disparate negative consequences of substance use. African American/Hispanic/Multiethnic youth formed one group, and youth identifying as White or Asian formed a second group. We hypothesized that (1) there would be significant disparities in psychosocial, serious problem behavior, and school-based consequences of substance use between White/Asian students compared to African American/Hispanic/Multiethnic students at baseline; (2) physical dependence consequences would not be disparate at baseline; and (3) overall disparities would be reduced at post-treatment follow-up. Results indicated that African American/Hispanic/Multiethnic adolescents demonstrated statistically significant disparate consequences at baseline, except for physical dependency consequences. Lastly, significant reductions in disparities were evidenced between groups over time. Our findings highlight the efficacy of utilizing school-based substance use interventions in decreasing ethnic health disparities in substance use consequences.

The Impact of Marijuana Legalization on Adolescent Use, Consequences, and Perceived Risk.

BACKGROUND: Currently, only four states have legalized recreational marijuana use for adults over 21 years of age. Therefore, little is known about the influence that legalization will have on adolescent marijuana use. OBJECTIVES: This study examines how marijuana legalization has impacted the frequency and consequences of adolescent use in a sample of participants in a school-based, substance use intervention. We hypothesized that adolescents enrolled in the intervention in years after marijuana legalization would present with more problematic use compared to those enrolled prior, and that changes in the perceived risk of marijuana would be a mechanism of problematic use. METHODS: Participants were 262 students enrolled in a school-based substance use intervention in 2010 to 2015. The Customary Drinking and Drug Use Record, Alcohol and Drug Use Consequences Questionnaire, and a decisional balance matrix were used to assess marijuana frequency, negative consequences, and perceived risk of use. A mediation model was used to test the degree to which marijuana legalization may lead to increased frequency and consequences of use through perceived risk. RESULTS: Findings indicated a significantly positive correlation between marijuana-related consequences and perceived risk post legalization. Despite relatively equal use between both groups, adolescents in the legalization group experienced higher levels of perceived risk and increased negative consequences. CONCLUSIONS/IMPORTANCE: Due to the rising legalization status of marijuana in the United States, it is imperative that psychoeducation is provided to adults and adolescents about the consequences of underage marijuana use.
