Multiple sclerosis: impact of physical activity on psychosocial constructs

Area of Science:

• Neurology
• Rehabilitation Science
• Behavioral Science

Background:

• Multiple sclerosis (MS) significantly impacts physical functioning and quality of life.
• Understanding the psychosocial factors influencing physical activity (PA) is crucial for effective management in MS.
• Previous research has explored various interventions, but the specific impact on psychosocial constructs needs further elucidation.

Purpose of the Study:

• To investigate the effects of PA interventions and accumulated PA experience on psychosocial constructs in individuals with MS.
• To examine the relationship between psychosocial factors (self-efficacy, self-identity, social support) and PA levels before and after interventions.

Main Methods:

• A cohort of 39 individuals with MS participated in PA interventions.
• Key variables including PA, self-efficacy, self-identity, social support, and expected PA frequency were measured pre- and post-intervention.
• Statistical analyses included MANOVA to assess changes in psychosocial constructs and regression analyses to determine associations with PA.

Main Results:

• MANOVA revealed significant improvements in self-identity and PA, alongside decreases in self-efficacy and expectation (P<0.05).
• Regression analyses demonstrated that pretest self-identity and social support were significant predictors of PA.
• Posttest self-efficacy and social support also showed significant associations with PA levels.

Conclusions:

• PA interventions and experience demonstrably alter psychosocial constructs in individuals with MS.
• These changes in psychosocial factors subsequently influence their correlation with physical activity engagement.
• Findings highlight the importance of addressing psychosocial elements in designing effective PA programs for MS.
