Mediating Role of Moral Disengagement Mechanisms in the Relationship Between Perceived Parental Warmth and Youth Violence

<b>Background/Objectives:</b> Although child-to-parent violence (CPV), peer violence (PV), and dating violence (DV) share risk factors and tend to co-occur, little is known about the common and differential mechanisms involved in the development of these types of youth violence. This study aims to (1) analyze the relationship between youth violence (CPV, PV, and DV) and perceived parental warmth and moral disengagement mechanisms and (2) explore the mediating role of moral disengagement mechanisms in the relationship between the lack of perceived parental warmth and youth violence. <b>Methods</b>: A cross-sectional population-based survey study was conducted. The sample consisted of 2124 Spanish adolescents (57.9% girls) aged between 13 and 17 years from educational centers. <b>Results</b>: The lack of perceived parental warmth (parental criticism-rejection in particular) is a common risk factor for all three types of violence and, more relevantly, is related to youth violence through moral disengagement mechanisms, highlighting a differential contribution of these mechanisms according to the type of violence. In particular, advantageous comparison and attribution of blame are specific mediators of CPV, and moral justification and distortion of consequences are specific to PV, whereas euphemistic language seems to be a common mediator of PV and DV. <b>Conclusions</b>: This study suggests that adolescents who perceive a lack of parental warmth are more likely to develop different dysfunctional cognitive mechanisms, which in turn are related to different types of youth violence. It would be important to promote warm parenting practices and address the cognitive mechanisms underlying youth violence.
