Is this trial a fit for you?

Likely a good fit

Adults (18+) with a documented diagnosis of borderline personality disorder or avoidant personality disorder who are receiving treatment at one of the two participating outpatient psychotherapeutic clinics in the Capital Region of Denmark and who are proficient in Danish.

Probably not a fit

People not treated at the participating clinics, those with a documented diagnosis of antisocial personality disorder (an exclusion), or individuals unable or unwilling to engage in regular physical activity may not benefit from or be eligible for these programs.

What this trial studies

This randomized, three-arm feasibility trial will enroll about 60 adults receiving outpatient care at two psychotherapeutic clinics in the Capital Region of Denmark and assign them to usual treatment, usual treatment plus an 8-week pedometer-based walking program, or usual treatment plus 8 weeks of supervised karate. The primary focus is on feasibility, acceptability, and safety, measured by screening, recruitment, retention, attendance, and adverse events. The trial will also measure changes in objective outcomes (body composition and fitness) and patient-reported outcomes such as emotion regulation, personality disorder symptoms, interpersonal functioning, recovery, physical activity behavior, and body awareness. Participant experiences will be explored qualitatively to understand acceptability and perceived impact and to inform the design of a larger definitive trial.

Why it matters

Potential benefit: If successful, these low-cost physical activity programs could offer safe, accessible ways to improve emotion regulation, interpersonal functioning, and physical health for people with borderline or avoidant personality disorder.

How similar studies have gone: Exercise interventions have shown benefits for mood and emotion regulation in other mental health conditions, but randomized evidence specifically in personality disorders—and using karate or pedometer walking—remains limited, so this is a relatively novel application.
