Scientists ask: is BPD really a 'Relationship use Disorder'?
NCT ID NCT07337889
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new idea: that Borderline Personality Disorder (BPD) may be a form of addiction to close relationships, similar to substance use disorders. Researchers will give a special questionnaire to 194 people—those with BPD, those with bipolar disorder, and healthy volunteers—to see if relationship addiction is stronger in BPD. The goal is to better understand BPD and reduce stigma, not to test a treatment.

- What this could lead to
- If this study confirms the addiction model, it could lead to new treatment approaches for BPD that focus on relationship patterns, similar to addiction therapies.
- What could go wrong
- This is an early observational study, not a treatment trial. The questionnaire is experimental, and the findings may not change current care or apply to all people with BPD.
