Effects of supervised physical exercise on emotions among adults with a diagnostic of borderline personality disorder: A series of mixed method single-case experimental trials combined with ecological momentary assessment

Résumé

Borderline personality disorder (BPD) is characterized by an instability of goals, self-image, interpersonal relationships, and affects. It is thought to be shaped around emotional dysregulation. Physical exercise is an effective way to improve emotional regulation in individuals both with and without mental disorder. However, to this day no study examined the effect of regular physical exercise on emotion regulation in adults with BPD. This study used a series of single case experimental design (A-B-A) combined with ecological momentary assessment and individual interviews to explore and analyze the effect of physical exercise on emotion regulation in adults with BPD. Emotions of participants were monitored thrice daily with an app that prompted them to report their emotions on a 0-100 analogue scale. Both A phases lasted 2 weeks (control measurement) and the B phase (intervention) lasted 4 weeks (3 1-hour supervised sessions of physical exercise weekly). Emotion related data were analyzed by piecewise linear regression and qualitative data with thematic analysis. Seven women with BPD on a waitlist for treatment completed this study and five of them participated in the interviews. Three participants showed an increase in positive emotions and four participants showed a decrease in negative emotions throughout the study. Interindividual analyses confirm these results with a greater decrease of negative emotions during the intervention. No significant effect was found on emotion variability. Participants reported enjoying the exercise program and the trainer they were assigned. Trainers’ characteristics were among the reasons of their adhesion to the program. Finally, participants also reported being less reactive and more patient when encountering irritating or stressing events. In conclusion, adult women with BPD found physical exercise acceptable, it decreased their negative emotions and reactivity to psychological stressors. It could therefore be used in addition to usual treatment to help alleviate BPD symptoms.
