Manual Assisted Cognitive Treatment for Deliberate Self-Harm in Borderline Personality Disorder Patients

Abstract

This study examines the efficacy of a short-term individual therapy, Manual Assisted Cognitive Treatment (MACT), which was developed to treat parasuicidal (suicidal or self-harming) patients. In this trial, MACT was modified to focus on deliberate self-harm (DSH) in patients with borderline personality disorder (BPD). Thirty BPD patients who were engaged in DSH while in ongoing treatments, i.e., treatment-as-usual (TAU), were randomly assigned to receive MACT (N = 15) or not. DSH and level of suicide ideation were assessed at the baseline, at completion of the MACT intervention, and six months later. Results indicated that MACT was associated with significantly less frequent DSH upon completion of the intervention and with significantly decreased DSH frequency and severity at the six months follow-up. Moreover, MACT's contribution to reducing DSH frequency and severity was greater than the contribution by the amount of concurrent treatments. In contrast, MACT did not affect the level of suicide ideation and time-to-repeat of DSH. In conclusion, MACT seems to be a promising intervention for DSH in patients with BPD. More definitive studies are needed.
