Understanding predictors of change in a day treatment setting for non-suicidal self-injury.

Patients who engage in NSSI show significant change from admission to discharge in a day treatment programme dedicated to the treatment of NSSI. Quality of life and functional impairment are important outcome variables to consider and evaluate in higher levels of care. It is important to consider demographic and clinical variables when creating a treatment plan for NSSI. Although BPD symptoms may be important to consider in day treatment for NSSI, interpersonal dysfunction, depressive symptoms, and mood lability may also affect change in symptoms.
