What this trial studies
Adults who meet full DSM-5-TR criteria for BPD and their consenting romantic partners will take part in a Phase 2 interventional comparison involving a partner-inclusive program (Sage) versus supportive individual psychotherapy, with sessions audio- and video-recorded. Both members must be at least 19 years old, live in Ontario, be fluent in English, consent to contact procedures for safety, and have private internet access for study appointments. The protocol excludes couples with severe intimate partner violence in the past year and includes safety monitoring for imminent risk. Key outcomes include BPD symptom change, relationship functioning, and partner mental health tracked over the course of treatment.
Who should consider this trial
Good fit: Adults (≥19) living in Ontario who meet full DSM-5-TR criteria for BPD and are in a romantic relationship with a partner willing to participate, fluent in English, and able to join private online sessions are ideal candidates.
Not a fit: People who are not in a consenting partnership, have had severe intimate partner violence in the past year, cannot participate in English, or cannot attend private online appointments are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this approach could reduce BPD symptoms more quickly and improve relationship functioning and partner mental health without large additional resource needs.
How similar studies have performed: Some couple-based approaches for related problems have shown promise, but partner-inclusive treatments specifically tailored for BPD are relatively novel and have limited prior evidence.
