In the present study, between-family analyses of data from adolescent twin girls offer new evidence that early menarche is associated with earlier initiation and greater frequency of smoking and drinking. The role of personality factors and peer relationships in that association was investigated, and little support was found for their involvement. Novel within-family analyses replicating associations of substance use with pubertal timing in contrasts of twin sisters selected for extreme discordance for age at menarche are reported. Within-family replications demonstrated that the association of pubertal timing with substance use cannot be explained solely by between-family confounds. Within-family analyses demonstrated contextual modulation of the influence of pubertal timing: Its impact on drinking frequency is apparent only among girls in urban settings. Sibling comparisons illustrate a promising analytic tool for studying diverse developmental outcomes.
在本研究中，对青春期双生女的数据进行的家庭间分析提供了新的证据，表明初潮早与吸烟和饮酒的开始时间更早及频率更高有关。研究了人格因素和同伴关系在这种关联中的作用，但几乎没有发现它们参与其中的证据。报告了新颖的家庭内分析，该分析在因初潮年龄差异极大而被选中的双胞胎姐妹的对比中，重现了物质使用与青春期时间的关联。家庭内的重复研究表明，青春期时间与物质使用之间的关联不能仅由家庭间的混杂因素来解释。家庭内分析表明了青春期时间影响的情境调节作用：其对饮酒频率的影响仅在城市环境中的女孩中明显。兄弟姐妹比较说明了一种用于研究不同发展结果的有前景的分析工具。
