BackgroundCaring for a family member with dementia is extremely stressful, contributes to psychiatric and physical illness among caregivers, and increases the risk for caregiver death. Finding better ways to support family caregivers is a major public health challenge.ObjectiveTo test the effects of a structured multicomponent intervention on quality of life and clinical depression in caregivers and on rates of institutional placement of care recipients in 3 diverse racial or ethnic groups.DesignRandomized, controlled trial.SettingIn-home caregivers in 5 U.S. cities.Participants212 Hispanic or Latino, 219 white or Caucasian, and 211 black or African-American caregivers and their care recipients with Alzheimer disease or related disorders.InterventionCaregivers within each racial or ethnic group were randomly assigned to an intervention or to a control group. The intervention addressed caregiver depression, burden, self-care, and social support and care recipient problem behaviors through 12 in-home and telephone sessions over 6 months. Caregivers in the control group received 2 brief "check-in" telephone calls during the 6-month intervention.MeasurementsThe primary outcome was a quality-of-life indicator comprising measures of 6-month caregiver depression, burden, self-care, and social support and care recipient problem behaviors. Secondary outcomes were caregiver clinical depression and institutional placement of the care recipient at 6 months.ResultsHispanic or Latino and white or Caucasian caregivers in the intervention group experienced significantly greater improvement in quality of life than those in the control group (P < 0.001 and P = 0.037, respectively). Black or African-American spouse caregivers also improved significantly more (P = 0.003). Prevalence of clinical depression was lower among caregivers in the intervention group (12.6% vs. 22.7%; P = 0.001). There were no statistically significant differences in institutionalization at 6 months.LimitationsThe study used only a single 6-month follow-up assessment, combined heterogeneous cultures and ethnicities into a single group, and excluded some ethnic groups.ConclusionsA structured multicomponent intervention adapted to individual risk profiles can increase the quality of life of ethnically diverse dementia caregivers.
