Nonsuicidal Self‐Injury, Stress, and Self‐Differentiation

The authors surveyed 458 young adults and examined the relationships among stress, self‐differentiation, and nonsuicidal self‐injury (NSSI). They conducted multiple regression analyses to explore whether characteristics of self‐differentiation (i.e., emotional reactivity and “I position”) were related to NSSI after controlling for the effects of stress, as well as whether emotional reactivity and I position served as mediators in the stress–NSSI relationship. I position and emotional reactivity both contributed statistically significant variance to NSSI after accounting for stress. Moreover, both I position and emotional reactivity served as partial mediators in the stress–NSSI relationship. The authors discuss counseling and research implications.
