Organized activities can provide a conducive context for various social processes that may prevent internalizing problems. Some types of organized activities, such as team sports, seem particularly favorable to these positive experiences. The aim of this 4-year longitudinal study is to describe the changes in the feeling of social integration into the organized activity peer group and to examine whether this social process predicts depressive symptoms in adolescence. Team sports also are proposed to promote a high sense of social integration. A total of 292 adolescents (62% female) were followed annually from ages 14 to 17. The type of main organized activity practiced and the feeling of social integration into the activity peer group was measured each year. Depressive symptoms were self-reported at the beginning and end of this period. Latent growth analyses showed that social integration into the organized activity peer group was high and decreasing during adolescence. Social integration was higher in team sports compared to individual sports and non-sport activities as a whole. Finally, a high and sustained level of social integration during adolescence was associated with a low level of depressive symptoms at the end of adolescence, controlling for important covariates. These results suggest that organized activities, particularly team sports, provide a favorable context for developing a feeling of social integration, and that this may protect against depressive symptoms.

体育和非体育组织活动中活动同伴群体的社会融合：与青春期抑郁症状的联系

有组织的活动可以为各种社会进程提供有利的环境，从而防止问题内部化。某些类型的有组织活动，例如团队运动，似乎特别有利于这些积极的经历。这项为期四年的纵向研究的目的是描述融入有组织的活动同伴群体的社会融入感的变化，并检验这种社会过程是否预示着青春期的抑郁症状。团队运动也被提议促进高度的社会融合感。每年对 292 名 14 岁至 17 岁的青少年（62% 为女性）进行跟踪调查。每年都会测量主要组织活动的类型以及融入活动同伴群体的社会融入感。在此期间的开始和结束时自我报告抑郁症状。潜在成长分析表明，在青春期，有组织的活动同伴群体的社会融入度很高，但在下降。与个人运动和非体育活动整体相比，团队运动的社会融合程度更高。最后，在控制了重要的协变量的情况下，青春期期间较高且持续的社会融合水平与青春期结束时较低水平的抑郁症状相关。这些结果表明，有组织的活动，特别是团队运动，为培养社会融合感提供了有利的环境，这可以预防抑郁症状。
