This study attempted to disentangle the effects of peer selection and socialization on heavy drinking and marijuana use among adolescents whose parents received 2 distinct brief interventions (BIs). It also examined whether the two BI models-Family Check-Up and Psychoeducation-had differential effects on peer processes. Parents were randomized to BI conditions and their adolescents (61% male, age 12-19 years) completed self-report measures of days of heavy drinking, days of marijuana use, and perceived peer substance involvement at baseline, 6 months, and 12 months. Separate cross-lagged panel models revealed evidence of selection and socialization for both heavy drinking and marijuana over the first 6 months and evidence of only selection over the subsequent 6 months. Consistent with prior studies, a less robust pattern of peer processes was found when simultaneously controlling for both heavy drinking and marijuana. Results highlight the need to examine multiple substances simultaneously and suggest that the BIs may have had protective effects on peer influences over time.
本研究试图厘清同伴选择和社交对父母接受两种不同简短干预（BI）的青少年酗酒和吸食大麻行为的影响。研究还考察了两种BI模式——家庭检查和心理教育——对同伴过程是否有不同影响。父母被随机分配到BI条件组，他们的青少年（61%为男性，年龄在12至19岁之间）在基线、6个月和12个月时完成了关于酗酒天数、吸食大麻天数以及感知到的同伴物质使用情况的自我报告测量。单独的交叉滞后面板模型显示，在前6个月中，酗酒和吸食大麻均有选择和社交的证据，而在随后的6个月中只有选择的证据。与先前研究一致，在同时控制酗酒和吸食大麻时，发现同伴过程的模式不太稳健。结果强调了同时检查多种物质的必要性，并表明BI可能随着时间推移对同伴影响起到了保护作用。
