This study evaluated how individuals' own substance use and their perception of peers' substance use predict each other across development from early adolescence to middle adulthood. Participants were from two longitudinal studies: Fast Track (FT; N = 463) and Child Development Project (CDP; N = 585). Participants reported on their own and peers' substance use during early and middle adolescence and early adulthood, and their own substance use in middle adulthood. From adolescence to early adulthood, individuals' reports of their own substance use in a given developmental period predicted reports of their peers' substance use in the next developmental period more than peers' substance use in a given developmental period predicted individuals' own substance use in the next. In the higher-risk FT sample, individuals' own substance use in early adulthood predicted alcohol, cannabis, and other substance use in middle adulthood, and peers' substance use in early adulthood predicted cannabis use in middle adulthood. In the lower-risk CDP sample, participants' own substance use in early adulthood predicted only their own cannabis use in middle adulthood, whereas peers' substance use in early adulthood predicted participants' alcohol, cannabis, opioid, and other substance use in middle adulthood. The findings suggest that peer substance use in early adulthood may indicate a greater propensity for subsequent substance use in lower-risk groups, whereas those in higher-risk groups may remain more stable in substance use, with less variability explained by peer contexts.
这项研究评估了个体自身的物质使用情况及其对同伴物质使用情况的看法如何在从青少年早期到成年中期的发展过程中相互预测。参与者来自两项纵向研究：快速轨道（FT；N=463）和儿童发展项目（CDP；N=585）。参与者在青少年早期和中期以及成年早期报告了自己和同伴的物质使用情况，并在成年中期报告了自己的物质使用情况。从青少年到成年早期，个体在特定发展阶段报告的自身物质使用情况比同伴在同一发展阶段的物质使用情况更能预测下一发展阶段的同伴物质使用情况。在高风险的 FT 样本中，个体在成年早期的物质使用情况预测了他们在成年中期的酒精、大麻和其他物质使用情况，而同伴在成年早期的物质使用情况则预测了他们在成年中期的大麻使用情况。在低风险的 CDP 样本中，参与者在成年早期的物质使用情况仅预测了他们在成年中期的大麻使用情况，而同伴在成年早期的物质使用情况则预测了参与者在成年中期的酒精、大麻、阿片类药物和其他物质使用情况。研究结果表明，成年早期同伴的物质使用情况可能表明低风险群体随后物质使用的倾向更大，而高风险群体的物质使用情况可能更稳定，同伴环境解释的变异性较小。
