The relations between childhood experience of negative parenting practices and nonsuicidal self-injury in Chinese adolescents: The mediating roles of maladaptive perfectionism and rumination

Abstract

Background: Nonsuicidal self-injury (NSSI) is a highly prevalent and serious public health concern among adolescents worldwide, and family experiences are influential in its development. However, the potential mediating mechanisms underlying the relations between childhood experience of negative parenting practices and NSSI are not fully understood. This study tested a mediating model to examine the roles of maladaptive perfectionism and rumination in these relations.

Methods: A total of 5,619 Chinese adolescents (54.7 % males; mean age = 15.92 years, SD = 0.73) participated in this study and completed self-report measures of negative parenting practices, maladaptive perfectionism, rumination, and NSSI.

Results: There were significant positive correlations among negative parenting practices, maladaptive perfectionism, rumination, and NSSI. In the mediation analyses, all negative parenting practices were indirectly related to NSSI via maladaptive perfectionism, while rumination only mediated the relation of maternal overprotection to NSSI. In addition, among all negative parenting practices, maternal rejection was the most closely associated with maladaptive perfectionism.

Conclusion: The findings of the study expand our understanding of the influences of negative parenting practices on NSSI. Clinicians may pay special attention to maternal rejection and focus on adolescents' maladaptive perfectionism and rumination when interacting with individuals with NSSI.
