Abstract

Borderline Personality Disorder (BPD) is a mental health disorder which affects approximately 1.7% of the US population. BPD is characterized by debilitating symptoms (including erratic relationships, emotional instability, and self-harm), comorbid diagnoses, high levels of treatment resistance, and heavy disease burden. Recent studies show that individuals with BPD continue to experience poor psychosocial functioning regardless of their remission status. These studies suggest that BPD clinical guidelines should emphasize Health Related Quality of Life (HRQoL) over the mere amelioration of symptoms. This study assessed the relationship between BPD treatment and patient outcomes (including diagnostic remission and quality of life). A custom survey was conducted from May 13th, 2025 to June 5th, 2025. The survey garnered 103 participants who met DSM-V BPD criteria, currently resided in the US, and were at least 18 years of age. Quantitative results were analyzed using SPSS via Paired Sample T-Tests, Binary Logistic Regressions, and Linear Regressions. Qualitative results were assessed through thematic analysis, including auto-coding and word frequency queries in NVivo. Data analysis identified positive associations between BPD symptom abatement and three different therapies: individual therapy, mindfulness-based therapy, and prescription drug therapy. Data analysis also indicated positive associations between both (1) HRQoL and BPD diagnostic remission & (2) HRQoL and BPD symptom abatement. However, the association between HRQoL and BPD symptom abatement was slightly stronger than the association between HRQoL and diagnostic remission. This indicates that, while diagnostic remission is a predictor of increased HRQoL, symptom abatement may be a superior predictor for long-term recovery from BPD. These findings provide several implications for the BPD clinical landscape, which is obstructed by cultural stigma, practitioner bias, and barriers to accessibility. Overall, this study highlights the need to shift BPD care into a patient-centered framework, thereby increasing BPD individuals’ access to autonomous, fulfilling lives.
