Harsh parenting and adolescent non-suicidal self-injury: A moderated mediation model of alienation and cognitive reappraisal

Harsh parenting has been shown to be associated with non-suicidal self-injury (NSSI) in adolescents. Based on the integrated theoretical model of the development of NSSI and the cognitive-emotional model of NSSI, we proposed a moderated mediation model to investigate "how" and "when" harsh parenting is associated with adolescent NSSI. Specifically, we tested whether feelings of alienation mediated the association between harsh parenting and NSSI, and whether this indirect effect was weakened by cognitive reappraisal as an adaptive emotion regulation strategy.A total of 1638 Chinese adolescents (54.7 % girls; ages 12-19 years) completed self-report questionnaires in their classrooms. The questionnaires assessed harsh parenting, feelings of alienation, cognitive reappraisal skills, and incidents of NSSI.Path analyses showed that harsh parenting positively predicted NSSI, and alienation mediated this association. Both the direct effect of harsh parenting on NSSI and the indirect effect through alienation were moderated by cognitive reappraisal. Specifically, cognitive reappraisal skills weakened the direct and indirect associations between harsh parenting and NSSI.Adolescents may benefit from interventions that decrease feelings of alienation and increase cognitive reappraisal strategies to reduce the risk of NSSI in the context of harsh parenting.
