This study profile describes COCON – the acronym for COmpetence and CONtext. This is an interdisciplinary, multi-cohort and multi-informant longitudinal study with a primary focus on how children and adolescents cope with the developmental tasks of early life course transitions. It strives to detect the social and individual antecedents and consequences associated with the handling of these transitions. The project frames child and adolescent development in the triple theoretical perspective of challenges imposed by early transitions in the institutionalised life course, inequality in resources and opportunities, and young people’s competencies. Thanks to the longitudinal and multi-cohort design of the study, this conceptual perspective facilitates the joint examination of intra-individual development, inter-individual differences in developmental outcomes and social change in developmental processes.COCON consists of three age groups, whereby each groups represents a prototypical stage in the process of growing up: mid-childhood (6-year-olds), mid-adolescence (15-year-olds) and early adulthood (21-year-olds). The samples are representative for the French- and German-speaking parts of Switzerland. The large sample sizes and the multilingual context of Switzerland permit the analysis of group disparities as well as cross-cultural differences. The multi-informant component of the study includes the primary caregiver and class teacher.The current study profile outlines the most important characteristics of the study in the context of the conceptual framework and discusses strengths and caveats related to study management as well as ethical considerations and information on data availability.

COCON – 瑞士儿童和青少年纵向调查

本研究简介描述了 COCON – COmpetence 和 CONtext 的首字母缩写词。这是一项跨学科、多队列和多信息的纵向研究，主要关注儿童和青少年如何应对早期生命历程转变的发展任务。它努力发现与处理这些转变相关的社会和个人的前因和后果。该项目以三重理论视角构建儿童和青少年发展的框架，即制度化生命过程中的早期过渡、资源和机会的不平等以及年轻人的能力所带来的挑战。由于研究的纵向和多队列设计，这种概念性观点有助于对个体内部发展的联合检查，COCON 由三个年龄组组成，每个组代表成长过程中的一个典型阶段：儿童中期（6 岁）、青春期中期（ 15 岁）和成年早期（21 岁）。这些样本代表了瑞士的法语和德语地区。瑞士的大样本量和多语言环境允许分析群体差异以及跨文化差异。该研究的多信息部分包括主要照顾者和班主任。
