Spousal support and self-determined physical activity in individuals with multiple sclerosis: A theory-informed qualitative exploration.

BACKGROUND

Individuals with multiple sclerosis (MS) tend to exhibit high levels of sedentary behavior which contributes to increased disability and comorbidity. Understanding what factors underlie the motivation to be physically active in this group is therefore important.

OBJECTIVE

This theory-informed qualitative study explored spousal support and behavior in fostering self-determined physical activity engagement of adults with MS.

METHODS

Eight couples were interviewed using a semi-structured interview guide derived from Self-Determination Theory.

RESULTS

Analysis of transcribed audio recordings revealed that supportive and empathetic spousal communication, encouragement and expectations regarding physical activity, and bonding through co-participation increased feelings of relatedness. In addition, co-planning and problem-solving around physical activity and serving as a behavioral model facilitated perceptions of competency, while spouses who valued their partners' independence and offered choice enhanced autonomous motivation for physical activity.

CONCLUSIONS

Insight into the marital context that supports self-determined physical activity decisions of individuals with MS may better inform family-oriented health promotion approaches in this group.
