Abstract

Introduction

Poor mental health is a common secondary health condition for adults with disabilities. The mental health benefits of moderate-to-vigorous intensity physical activity (MVPA) are well-documented. Few studies have empirically tested the relationship between MVPA and mental health among persons with disabilities. Additionally, theoretically-informed factors that may mediate the relationship are not commonly tested among persons with disabilities. The primary aim of this study was to examine the cross-sectional relationship between MVPA and mental health in adults with disabilities. A secondary aim was to explore the indirect effects of the three psychological needs (autonomy, competence, relatedness) on the MVPA-mental health relationship.

Material and methods

Participants (n = 100; mean age = 36.61; 54% women; 84% physical disability) completed an online questionnaire to assess MVPA, mental health, autonomy, competence, and relatedness. The associations between MVPA, psychological needs, and mental health were explored descriptively and in a multiple mediation regression model.

Results

The bivariate association between MVPA and mental health was significant (rs = 0.34, p = 0.01), as were the associations between the three psychological needs and MVPA (rs = 0.24–0.43) and mental health (rs = 0.61–0.82). MVPA had a significant indirect effect on mental health through autonomy (β = 0.05, 95% CI = 0.00–0.12), competence (β = 0.16, 95% CI = 0.08–0.25) and relatedness (β = 0.08, 95% CI = 0.02–0.17).

Conclusions

The results of this study add to limited research documenting the relationship between MVPA and mental health in adults with disabilities by highlighting the potential benefits of autonomy, competence, and relatedness. Future prospective research is needed to investigate the mediating effects of autonomy, competence and relatedness on the relationship between MVPA and mental health in adults with disabilities.
