The chain mediating role of cognitive styles and alienation between life events and depression among rural left-behind children in poor areas in Southwest China

Compared with no-left-behind children, left-behind children show more psychological and behavioral problems, among which depression is the most common and most influential psychological problem in childhood. Many studies have documented the impact of life events on depression among left-behind children, but few studies have focus on the mediating mechanisms behind this relationship. Based on theoretical and empirical research on cognitive style and alienation, this study constructed a chain mediation model to test whether cognitive style and alienation play a mediating role in life events and depression of left-behind children.We recruited 13,035 participants from 25 districts and counties in Chongqing. After screening, 5127 questionnaires of left-behind children were included in the data analysis. They all completed self-report measures of demographic information, life events, cognitive styles, alienation and depression. We used SIF, CDI, ASLEC, CCSQ and IAP to collect the information of the variables and used the SPSS to analyze the data.(1) There were significant positive correlations among life events and depression. (2) Left-behind children's depression was affected by life events through 3 different pathways: the mediating role of cognitive styles, the mediating role of alienation, and the chain mediating role of both cognitive styles and alienation.This is a cross-sectional study and the data used in our study is self-reported.Cognitive styles and alienation could mediate the association between life events and depression among left-behind children.
