Dialectic behavioural therapy has an impact on self-concept clarity and facets of self-esteem in women with borderline personality disorder.

Identity disturbance and an unstable sense of self are core criteria of borderline personality disorder (BPD) and significantly contribute to the suffering of the patient. These impairments are hypothesized to be reflected in low self-esteem and low self-concept clarity. The objective of this study was to evaluate the impact of an inpatient dialectic behavioral therapy (DBT) programme on self-esteem and self-concept clarity.
