Examining the mediator and moderator of the link between Migration-Related stress and depression amongst Chinese migrant children

Migration-related stress is detrimental to children's mental health, yet little is known about the potential mechanisms behind this association. This study examines the mediating role of inflow city identity in the association between migration-related stress and depression and the moderating role of social participation amongst Chinese migrant children. A sample of 484 migrant children aged 8-17 years is randomly recruited through a cross-sectional survey in Kunming, China. Inflow city identity partially mediates the association between migration-related stress and migrant children's depression. Moreover, social participation moderates the above relationship. The direct and indirect effects are significant for migrant children with low social participation but insignificant for migrant children with high social participation. This study deepens the theoretical understanding of the underlying mechanism between migration stress and psychological distress and provides practical implications for preventing mental disorders in Chinese migrant children.
