title: Brief report: self-harm is associated with immature defense mechanisms but not substance use in a nonclinical Scottish adolescent sample.
abstract: It has been unclear whether adolescent deliberate self-harm (DSH) is more associated with substance use or with characterological impairments. Multivariate determination of (N = 114 Scottish adolescents) ever engaging in DSH (Youth Risk Behavior Survey) from alcohol use, other substance use, and immature defense mechanism use (Defense Style Questionnaire; DSQ-40) revealed that a history of DSH was associated with more use of immature defense mechanisms by not with substance use or recent alcohol use. More research and clinical attention might be given to immature defense mechanisms in cases of DSH.
