Family cohesion, burden, and health-related quality of life among Parkinson's disease caregivers in Mexico.

ABSTRACTBackground:Informal caregivers of individuals with Parkinson's disease face a range of responsibilities that increase as the disease progresses. As a result of these stressors, caregivers are vulnerable to decreased health-related quality of life (HRQOL). Guided by the stress process model of caregiving, the present study examined the relations between family cohesion, perceived burden, and mental and physical HRQOL among Parkinson's disease caregivers in Mexico. It was hypothesized that perceived burden would mediate the relations of family cohesion and mental and physical HRQOL.

METHODS: Ninety-five family caregivers of individuals with Parkinson's disease in Mexico City, Mexico, participated in the study. Multiple regression was utilized to conduct mediation analyses.

RESULTS: Results indicated that burden fully mediated the relation between family cohesion and mental HRQOL, and family cohesion was not associated with physical HRQOL.

CONCLUSIONS: Findings extend the stress process model cross-culturally and lend support for the importance of family cohesion and perceived burden in determining caregiver mental HRQOL. Clinical health promotion interventions should target perceived burden and family cohesion together to improve mental HRQOL among familial caregivers in Mexico.
