Although Bowlby proposed that adolescence is a major developmental period to transfer their attachment figures from parents to other people, no comprehensive longitudinal study on attachment transfer from early to late adolescence exists. This study employed 215 early to late adolescents between ages 11 and 18 years (${\overline{X}}_{age}$ = 14.02, SD = 2.05 at Wave 1), using a six-wave 2-year longitudinal design with four different cohorts: 5th, 7th, 9th, and 11th grades. Both person- and variable-oriented analyses revealed that once adolescents have transferred their attachment figures from parents to peers, they were unlikely to revert to parents in the future. The transfer of attachment from parents to friends is more prevalent in early adolescence than in late adolescence. However, throughout adolescence, friends were not considered to be exclusive attachment figures, whereas parents and romantic partners were. Finally, many adolescents spent 4 months or fewer until their romantic partner became the primary attachment figure.

尽管鲍比（Bowlby）提出青春期是将他们的依恋对象从父母转移到其他人的主要发展时期，但尚无关于从早期到晚期的依恋转移的全面纵向研究。这项研究雇用了11至18岁之间的215名早期至晚期青少年（${\overline{X}}_{\mathrm{一种}GË}$= 14.02，在第1浪时SD = 2.05），使用六波2年纵向设计，具有四个不同的群组：5年级，7年级，9年级和11年级。以人为导向和以变量为导向的分析都表明，一旦青少年将依恋数字从父母转移到了同龄人，将来就不太可能重返父母。从父母到朋友的依恋转移在青春期初期比在青春期后期更为普遍。但是，在整个青春期，朋友不被视为专属的依恋对象，而父母和浪漫伴侣则被视为专属。最终，许多青少年花了四个月或更短的时间，直到他们的浪漫伴侣成为主要的依恋对象。
