Borderline Symptom List

The Borderline Symptom List (BSL) is a comprehensive self-report questionnaire with 95 items designed to assess symptoms of borderline personality disorder (BPD). It evaluates emotional, cognitive, and behavioral difficulties such as impulsivity, emotional instability, identity disturbance, and interpersonal challenges. Mental health professionals utilize the BSL for evaluating and monitoring BPD symptoms, guiding treatment planning, and assessing treatment outcomes.
