The effects of peers on three domains of alcohol expectancies through early adolescence were prospectively examined over 2 years. Information on pubertal development, parental drinking, peer characteristics, network structure, alcohol expectancies, and alcohol consumption was assessed in a three-wave longitudinal study of 779 6th graders (~12 years of age) randomly selected from northern Taiwan. Complex survey regression analyses, stratified by drinking experience in 6th grade, were performed to identify predictors of two positive (i.e., enhanced social behaviors and relaxation/tension reduction) and one negative alcohol expectancies (i.e., cognitive/behavioral deterioration) in 7th grade. The results showed that the effects of peer influence on adolescents' alcohol expectancies varied by prior drinking experiences and by expectancy domains. For the alcohol naive, recent exposure to peer drinking was significantly associated with positive and negative alcohol expectancies in grade 7, and this association was moderated by advanced pubertal development (ESBlate puberty: ßwt=0.55; ESBearly puberty: ßwt=-0.40; PRTRlate puberty: ßwt=0.01; PRTRearly puberty: ßwt=1.22; CBD late puberty: ßwt=-0.84; CBDearly puberty: ßwt=0.56). For the alcohol experienced, neither peer drinking nor pubertal development showed any significant links with alcohol expectancies. Occupying a bridge position was slightly linked with negative expectancy (ßwt=0.25). Concurrent drinking serves as a strong predictor for the endorsed alcohol expectancy in both groups, particularly for the domain of enhanced social behaviors. If these effects are confirmed, knowledge of the effect of interplay between peer factors and pubertal development on alcohol expectancies in early adolescence can provide effective targets in prevention programs.
在两年时间里，对同伴在青春期早期对酒精预期三个方面的影响进行了前瞻性研究。在一项对从台湾北部随机选取的779名六年级学生（约12岁）进行的三波纵向研究中，评估了青春期发育、父母饮酒情况、同伴特征、社交网络结构、酒精预期和酒精消费等信息。进行了复杂的调查回归分析，并按六年级的饮酒经历分层，以确定七年级时两种积极（即增强社交行为和放松/减轻紧张）和一种消极酒精预期（即认知/行为恶化）的预测因素。结果表明，同伴影响对青少年酒精预期的作用因先前饮酒经历和预期方面而异。对于未饮酒者，最近接触同伴饮酒与七年级时的积极和消极酒精预期显著相关，且这种关联受到青春期发育提前的调节（社交行为增强：青春期后期β权重=0.55；青春期早期β权重=-0.40；放松/减轻紧张：青春期后期β权重=0.01；青春期早期β权重=1.22；认知/行为恶化：青春期后期β权重=-0.84；青春期早期β权重=0.56）。对于有饮酒经历者，同伴饮酒和青春期发育与酒精预期均无显著关联。占据桥梁位置与消极预期略有关联（β权重=0.25）。同时饮酒是两组中认可的酒精预期的有力预测因素，尤其是在增强社交行为方面。如果这些影响得到证实，了解同伴因素与青春期发育之间的相互作用对青春期早期酒精预期的影响，可为预防项目提供有效的干预靶点。
