Abstract (Summary)

The objective of the study was to examine self-injury and interpersonal relationship difficulties in adults diagnosed with major depressive disorder (MDD). Thirty-eight participants diagnosed with MDD were selected from a larger study on borderline personality disorder, mood disorders, and suicidal behavior. Of the sample, 17 participants denied a history of suicidal acts and non-suicidal self-injury (NSSI) and 21 reported engaging in at least one previous suicide attempt (actual, ambiguous, interrupted, or aborted) or NSSI. Assessments of depression, self-injury, rejection sensitivity (RS), insecure attachments (attachment anxiety and attachment avoidance), and trauma were conducted. There was no significant difference between those with a history of self-injury and those without a history of self-injury on rejection sensitivity, attachment anxiety, and attachment avoidance. Depression severity had a significant association with rejection sensitivity and attachment anxiety. Trauma history was a significant predictor of history of self-injury. The current study highlights the relationships between depressive symptoms and interpersonal functioning, and trauma history and self-injury. Given the rate and severity of self-injury among individuals with MDD, research should continue to examine risk factors in this population and prioritize the development and utility of preventative interventions that focus on interpersonal effectiveness.
