Building Better Caregivers (BBC), a community 6‐week, peer‐led intervention, targets family caregivers of those with cognitive impairments. BBC was implemented in four geographically scattered areas. Self‐report data were collected at baseline, 6 months, and 1 year. Primary outcome were caregiver strain and depression. Secondary outcomes included caregiver burden, stress, fatigue, pain, sleep, self‐rated health, exercise, self‐efficacy, and caregiver and care partner health care utilization. Paired t tests examined 6 month and 1‐year improvements. General linear models examined associations between baseline and 6‐month changes in self‐efficacy and 12‐month primary outcomes. Eighty‐three participants (75% of eligible) completed 12‐month data. Caregiver strain and depression improved significantly (Effect Sizes =.30 and.41). All secondary outcomes except exercise and caregiver health care utilization improved significantly. Baseline and 6‐month improvements in self‐efficacy were associated with improvements in caregiver strain and depression. In this pilot pragmatic study, BBC appears to assist caregivers while reducing care partner health care utilization. Self‐efficacy appears to moderate these outcomes.
