Personality, Identity and Relationships Development of Adolescent Sojourners

居住流动性（即永久或临时、有意或被迫的迁移）已成为21世纪个人生活管理的主要挑战之一。例如，国际学生交流已经受到青少年的高度重视。采用前瞻性对照组设计（结合日记研究），本项目旨在研究出国（约1年）对青少年个性、身份和社会关系发展的影响。本文将探讨哪些人格和身份特征使青少年倾向于移居国外（选择效应），哪些旅居对随后的个体发展产生影响（社会化效应），以及哪些社会关系（家庭与同伴、家庭与主人、线下与线上、强与弱关系）可能发挥中介作用（中介效应）。此外，还将研究旅居背景下人格和身份发展之间的动态相互作用（交易效应）。这个项目增加了对青少年一般人格发展的理解，并阐明了在人类生命历程的各个阶段变得越来越相关的社会现象。

Residential mobility (i.e., moves that either are permanent or temporary, deliberate or forced) has become one of the major challenges to individual life management in the 21th century. For example, international student exchanges are highly valued already among adolescents. Using a prospective control group design (with integrated diary study), this projects sets out to study the consequences of staying abroad (for about 1 year) for the development of personality, identity and social relationships in adolescence. It will be investigated, which personality and identity characteristics predispose adolescents for moving abroad (selection effects), which consequences sojourning has on subsequent individual development (socialization effects), and which mediating role social relationships (family vs. peers, home vs. host, offline vs. online, strong vs. weak ties) may play (mediation effects). Furthermore, the dynamic interplay between personality and identity development in the sojourning context will be examined (transaction effects). This project adds to the understanding of general personality development in adolescence and sheds light on a social phenomenon that becomes increasingly relevant at all stages of the human life course.
