Borderline personality disorder (BPD) is a life-threatening, costly public health crisis affecting ~1-3% of North Americans, with 10% dying by suicide and annual healthcare costs of ~$63k (Canadian Dollars)/patient. Further, people with BPD's intimate relationships are highly disrupted, and their partners report elevated mental health problems but little access to treatment. Existing BPD treatments are resource-heavy, inaccessible, and 47% of people with BPD do not respond to them. These treatments also neglect relationship problems and intimate partner's mental health concerns, even though they are thought to play a key role in BPD maintenance. BPD interventions may produce stronger, quicker, and more durable outcomes if they incorporated partners to target both the emotional and relationship core of BPD. Moreover, incorporating partners into interventions may improve relationship outcomes and partner mental health without added resource investments.
Accordingly, members of our team developed Sage. Named after a plant that thrives in relationship with its ecosystem, Sage is a brief, 12-session conjoint intervention for people with BPD and their intimate partners that targets BPD, relationship conflict, and partner mental health. Our recent uncontrolled trial provides preliminary support for its efficacy.
As a next step in testing Sage, it is critical to utilize a Randomized Controlled Trial (RCT) design to identify if Sage is more efficacious than standard care that these couples typically receive; supportive individual psychotherapy (SIP) for people with BPD and their partners. The investigators propose to conduct the first RCT of Sage for couples wherein one member has BPD. The study will examine if Sage is more efficacious than SIP in improving BPD symptoms (primary outcome), as well as relationship conflict and partner mental health (secondary outcomes), as well as a range of other outcomes, from pre- to post-intervention, and post-intervention to follow-up. It will also investigate factors that influence treatment response, BPD severity, and related problems.
Up to 152 couples wherein one member has BPD will be randomized to receive Sage or SIP. Gold-standard measures of primary, secondary, and exploratory outcomes will be administered at baseline, mid-intervention, post-intervention, and a one-month, three- month, and six-month follow-up.

| Sage | Behavioral | Sage is a 12-session manualized weekly intervention delivered to people with borderline personality disorder (BPD) and their intimate partners. The Sage intervention consists of three phases: Phase 1, orientation and safety which focuses on targeting destructive behaviours (e.g., suicide attempts and self harm engagement) by providing couples with safety strategies that target suicide risk/ crisis, education about BPD, the role of emotion dysregulation and intimate relationship dysfunction in maintaining it (~three sessions). Next, Phase 2, communication and emotion skills entails couples learning communication skills and strategies for identifying, expressing, and regulating emotions (~five sessions). Lastly, in Phase 3, cognitive skills and intervention termination, couples learn strategies to target negative cognitions that elicit emotion dysregulation and intimate relationship dysfunction (~four sessions). |

De-identified data will be posted on a public, online data repository for the purpose of sharing it with the broader scientific community, to promote integrity and transparency in our research and allow other researchers to replicate our results from an open science framework. Demographic data will be shared only in grouped form for the entire sample (e.g., the average age of the sample, the frequencies of various racial/ethnic groups in the sample) except for participant's gender, which will be posted at the individual, rather than group, level.

| Supportive Individual Psychotherapy | Behavioral | Supportive Individual Psychotherapy (SIP) is a comparator in our control condition reflects enhanced usual care (i.e., supportive psychotherapy) for people with BPD. Both people with BPD and partners will receive SIP sessions separately over the course of 12 sessions, delivered by therapists. For both members of the couple, SIP will involve 12 sessions of a specific form of supportive psychotherapy based on client-centered, humanistic principles. This intervention involves creating a supportive therapeutic relationship, expressing empathy, and helping individuals feel understood. The SIP intervention is designed to support individuals in exploring their relationships and communication patterns as well as following the client's lead on what they want to work on. |
