Objectives: To determine whether there are racial and ethnicity group differences in Resources for Enhancing Alzheimer's Caregiver Health (REACH II) intervention delivery. Design: Randomized controlled trial. Setting: Community-based intervention delivered at five sites across the United States. Participants: Family caregivers of persons with dementia who were randomized to the active intervention condition (N = 323). Intervention: Nine in-home sessions (90 minutes each) and three telephone sessions (30 minutes each) were intended to be delivered and designed to reduce caregiver burden and depression, improve caregiver self-care and social support, and help caregivers manage behavior problems in persons with dementia. Measurements: Interventionists recorded the type of intervention (home or telephone), start and stop times, and whether specific intervention content modules (e.g., stress management, social support) were administered in each session. Results: Overall, REACH II intervention delivery was high, with more than 80% of randomized caregivers completing at least five in-home sessions and receiving eight or more hours of intervention contact, but black caregivers completed fewer in-home sessions (mean 6.98) than Hispanics (mean 7.84) or whites (mean 8.25) and received less total intervention contact time (mean 683 minutes) than Hispanics (mean 842 minutes) or whites (mean 798 minutes). No significant differences in exposure to content according to race or ethnicity were found after controlling for demographic covariates. Conclusion: Blacks in REACH II received significantly less intervention contact. Similar multicomponent interventions should examine whether there are systematic differences in intervention delivery across specific demographic subgroups and explore implications for treatment outcomes.
