Physical Activity in the Management of Personality Disorders: Protocol for a Three-Arm Randomized Feasibility Trial (The PANDA Trial)

What this Trial Is About

Researchers are evaluating the safety, feasibility, and acceptability of two types of physical activity—an 8-week pedometer-based walking program and supervised karate training—combined with usual treatment for adults diagnosed with borderline or avoidant personality disorders. The study aims to explore whether these activities are manageable and safe while observing possible effects on physical health, fitness, emotions, personality symptoms, body image, and daily activity. This trial will help determine if a larger study can be done in the future to assess benefits for people with these personality disorders. Participants are randomly assigned to one of three groups: usual treatment only, usual treatment plus the walking program, or usual treatment plus supervised karate training. The walking program involves tailored goals, daily step recording with a pedometer, and regular check-ins over 8 weeks. The karate program includes twice-weekly group sessions led by experienced instructors, featuring meditation, basic karate techniques, partnered exercises, and stretching. After the 12-week follow-up, those in the control or walking groups may choose to join the karate program. Participants attend assessments at baseline, 8 weeks, and 12 weeks, including physical tests like body composition and cardiorespiratory fitness, and self-report questionnaires. The 12-week follow-up questionnaires can be completed online at home. Safety is monitored through bi-weekly questionnaires for adverse events during the intervention period and medical record reviews through follow-up. Interviews with some participants will explore their experiences and views on the activities. The total study participation lasts about 12 weeks, with some continuing karate training afterward if desired.
