Is physical activity related to a reduction in the severity of borderline personality disorder through less severe insomnia disorder?

INTRODUCTION: Borderline personality disorder (BPD) is associated with severe suffering and insomnia disorder (ID) (Fertuck et al., 2016; Galbiati et al., 2020). OBJECTIVES: The aim was to investigate the negative association between self-reported physical activity (PA) and the severity of BPD with ID acting as a mediator (St-Amour et al., 2021). METHODS: The role of ID within the association of PA with BPD was tested using mediation analysis with the statistical program R 4.3 (N = 120; RStudio Team, 2020). RESULTS: [Table: see text] Image: CONCLUSIONS: Accordingly, ID does not appear to affect the association of PA and BPD severity whereas fewer PA and severe ID can nonetheless have a positive association with the symptoms of BPD in independent ways.
