Improving Research Practice for Studying Borderline Personality Disorder: Lessons From the Clinic.

Borderline personality disorder is an often misunderstood and underdiagnosed mental illness characterized in part by affective lability. Clinicians' unique understanding of the disorder has allowed them to develop disorder-specific approaches to treatment. In this review, we highlight how borderline personality disorder research can benefit from greater engagement with key disorder-specific features, including symptom variability and interpersonal sensitivity. In addition, we propose that research which employs interactive tasks will be more reflective of the kinds of volatility found in the real-life situations. Finally, we discuss how mixed-methodology can serve as a way for recovery-oriented research to practice the very ideals and recommendations it suggests. We use a patient case to contextualize each section. As interest in borderline personality disorder continues to grow, an intentional emphasis on a person-centered, recovery-focused, and disorder-specific approach to research is needed.
