Peer attachment and self-esteem mediate the relationship between family function and social anxiety in migrant children in China

Background Social anxiety is a frequently reported symptom in children and adolescents. The literature suggests that family function is related to symptoms of social anxiety in children. However, relatively little is known about the potential mechanisms underlying the relationship between family function and social anxiety. Thus, the purpose of the present study is to examine the roles of peer attachment and self-esteem in the relationship between family function and social anxiety in a sample of migrant children in China. Methods A total of 437 participants (54.9% male; mean(age) = 10.87 years) were selected from two public schools of migrant children in two areas of Hangzhou and Jiaxing, the major labor-importing cities in China, in May 2016. All participants completed four questionnaires assessing family function, peer attachment, self-esteem, and social anxiety. Results The results showed that family function was bivariately and significantly related to symptoms of social anxiety. Additionally, self-esteem fully mediated the relationship between family function and social anxiety peer attachment. Moreover, the relationship between family function and social anxiety was fully mediated by peer attachment and self-esteem (in that order). Conclusions Peer attachment and self-esteem serve as critical pathways linking family function and social anxiety. Thus, tailored interventions should consider the roles of peer attachment and self-esteem to alleviate symptoms of social anxiety in migrant children.
