Role Strains and Mood in Husbands of Women with Fibromyalgia Syndrome: A Test of the Stress Process Model

Abstract

Spouses of patients experience role strains as a result of informal caregiving, which has been associated with mood in numerous research studies. However, most research is on female caregivers, and little is known about the experi- ence of male spouses, or of the caregiving provided to fibromyalgia patients. The Stress Process Model was used to exam- ine mediators and moderators of the relation between role strain and mood among 135 husbands of women with fibromy- algia. Results indicated that the more activities of daily living and instrumental activities of daily living performed by the husband, the greater the role strain. Role strain was associated with worse mood. A test of the Stress Process Model sup- ported a partial mediation model, where social support and emotion-focused coping partially mediated the relation be- tween role strain and mood. No evidence was found for a moderation model or for problem-focused coping as a mediator. Our research suggests significant impairment and caregiving needs among this patient population, which in turn relates to the mood of the husband who is also an informal caregiver. Our findings also support the Stress Process Model in explain- ing the complexity of caregiving effects. The results of the study suggest avenues for intervention for individuals strained by their partners' illness.
