Abstract: Objective To explore the impact of childhood trauma on health risk behaviors of rural left-behind children and mediating effect of parenting styles on this impact,in order to prevent and intervene health risk behaviors of rural left-behind children. Methods A total of 364 rural left-behind children were surveyed by the Adolescent Health Related Risky Behavior Inventory (AHRBI),the Childhood Trauma Questionnaire-Short Form (CTQ-SF) and the Egna Minnen av Barndoms Uppfostran (EMBU) from March to May 2016. Results 1) The health risk behaviors of rural left-behind children were significantly positively related to childhood traumas(r=0.12～0.31,P<0.05),negatively related to authoritative parenting style (r=-0.21～-0.48,P<0.01) and positively correlated with authoritarian and permissive/neglecting parenting styles (r=0.12～0.36,P<0.05); 2) Childhood traumas were significantly negatively related to authoritative parenting style (r=-0.11～-0.44,P<0.05) and positively related to authoritarian and permissive/neglecting parenting styles (r=0.12～0.47,P<0.05); 3)The moderating effect of parenting styles on the impact of childhood trauma on health risk behaviors of rural left-behind children was significant,and the structural equation model was statistical powerful (χ²/df=2.774～3.460,IFI=0.91～0.92,CFI=0.90～0.92,GFI=0.93～0.94,RMSEA=0.07～0.08). Conclusion Childhood trauma is an important risk factor for health risk behaviors of rural left-behind children,and authoritative parenting styles act as the role of positive moderating effect between them,while authoritarian and permissive/neglecting parenting styles act as the roles of negative moderating effect.
