Self-harm typically occurs in adolescence and has been conceptualized as a dysfunctional strategy to regulate intense negative emotions. Furthermore, empirical literature outlines that self-harmers are more prone to have an insecure attachment style. Moreover, the link between quality of attachment and capacity to regulate emotions has been theoretically and empirically supported.

To examine the associations between attachment style, self-harm behaviors and emotion dysregulation among a sample of adolescents. The sample consisted of 740 adolescents aged between 13 and 19 years (mean age = 16.70, SD = 0.91).

To explore the nature of different pathways by which insecure attachment leads to self-harm behaviors.

As expected, insecure attachment and emotion dysregulation were positively associated with self-harm behaviors. Moreover, emotion dysregulation mediated the link between attachment styles and self-harm. Specific pathways between types of insecure attachment dimension of emotion dysregulation and self-harm behaviors emerged.

Such results confirm the theorization of self-harm behaviors as a dysfunctional strategy to regulate emotions. Moreover, such emotion dysregulation in self-harmers seem to be connected to insecure attachment. Depending on the subtype of insecure attachment, specific dimensions of emotion dysregulation seem to be involved in self-harm behavior, suggesting interesting clinical implications.
