The moderating role of close friends in the relationship between conduct problems and adolescent substance use.

ABSTRACT: Conduct problems and peer effects are among the strongest risk factors for adolescent substance use and problem use. However, it is unclear to what extent the effects of conduct problems and peer behavior interact, and whether adolescents' capacity to refuse the offer of substances may moderate such links. This study was conducted to examine relationships between conduct problems, close friends' substance use, and refusal assertiveness with adolescents' alcohol use problems, tobacco, and marijuana use.We studied a population-based sample of 1,237 individuals from the Cardiff Study of All Wales and North West of England Twins aged 11-18 years. Adolescent and mother-reported information was obtained. Statistical analyses included cross-sectional and prospective logistic regression models and family-based permutations.Conduct problems and close friends' substance use were associated with increased adolescents' substance use, whereas refusal assertiveness was associated with lower use of cigarettes, alcohol, and marijuana. Peer substance use moderated the relationship between conduct problems and alcohol use problems, such that conduct problems were only related to increased risk for alcohol use problems in the presence of substance-using friends. This effect was found in both cross-sectional and prospective analyses and confirmed using the permutation approach.Reduced opportunities for interaction with alcohol-using peers may lower the risk of alcohol use problems in adolescents with conduct problems.

Project description:Background and aimsThere is a documented link between common psychiatric disorders and substance use in adolescent males. This study addressed two key questions: (1) is there a within-person association between an increase in psychiatric problems and an increase in substance use among adolescent males and (2) are there sensitive periods during male adolescence when such associations are more evident?DesignAnalysis of longitudinal data collected annually on boys selected randomly from schools based on a comprehensive public school enrollment list from the Pittsburgh Board of Education.SettingRecruitment occurred in public schools in Pittsburgh, Pennsylvania, USA.ParticipantsA total of 503 boys assessed at ages 13-19 years, average cooperation rate = 92.1%.MeasurementsDiagnostic and Statistical Manual (DSM)-oriented affective, anxiety and conduct disorder problems were measured with items from the caregiver, teacher and youth version of the Achenbach scales. Scales were converted to t-scores using age- and gender-based national norms and combined by taking the average across informants. Alcohol and marijuana use were assessed semi-annually by a 16-item Substance Use Scale adapted from the National Youth Survey.FindingsWhen male adolescents experienced a 1-unit increase in their conduct problems t-score, their rate of marijuana use subsequently increased by 1.03 [95% confidence interval (CI) = 1.01, 1.05], and alcohol quantity increased by 1.01 (95% CI = 1.0002, 1.02). When adolescents experienced a 1-unit increase in their average quantity of alcohol use, their anxiety problems t-score subsequently increased by 0.12 (95% CI = 0.05, 0.19). These associations were strongest in early and late adolescence.ConclusionsWhen adolescent boys experience an increase in conduct disorder problems, they are more likely to exhibit a subsequent escalation in substance use. As adolescent boys increase their intensity of alcohol use, they become more likely to develop subsequent anxiety problems. Developmental turning points such as early and late adolescence appear to be particularly sensitive periods for boys to develop comorbid patterns of psychiatric problems and substance use.
