The mediating role of childhood maltreatment in the association between residence migration and adolescent depression.

BACKGROUND

It is well established that residence migration can negatively affect the mental health of adolescents. However, the related factors that mediate the association between residence migration and depression are still uncertain.

METHODS

The participants were 16,037 adolescents in junior middle schools. A self-administered questionnaire was used for the survey. In addition to collecting general demographic characteristics of the participants, including age, gender, local residence status, only child status, parental marriage status and parent-child relationship, the questionnaire also contained the 9-item Patient Health Questionnaire, the short form of the Childhood Trauma Questionnaire and the Connor-Davidson Resilience Scale. Data analysis was conducted using SPSS software.

RESULTS

A total of 14,059 valid questionnaires were collected, resulting in 12,122 local adolescents, defined as being born and raised locally, and 1937 migrant adolescents, defined as being transferred from other regions. Meanwhile, 53.3 % of local adolescents and 58.2 % of migrant adolescents reported depressive symptoms. This result indicated that residence migration might contribute to depression symptoms(OR = 1.136, 95%CI: 1.013-1.273, p < 0.05). Childhood maltreatment and parental divorce are risk factors for depression in migrant adolescents. For all adolescents, resilience and a good parent-child relationship may reduce the risk of depression. Childhood maltreatment completely mediates residence migration-related depression(95 % bootstrap CI = 0.146, 0.323).

CONCLUSION

This study revealed that residence migration could contribute to adolescent depression, and childhood maltreatment may largely mediate this process, providing new insight into the relationship between adolescent depressive symptoms and residence migration. Reducing childhood maltreatment may effectively improve the depressive symptoms of migrant adolescents.
