How Effective Are Interventions With Caregivers? An Updated Meta-Analysis

The combined interventions produced a significant improvement of 0.14 to 0.41 standard deviation units, on average, for caregiver burden, depression, subjective well-being, perceived caregiver satisfaction, ability/knowledge, and care receiver symptoms. Intervention effects were larger for increasing caregivers' ability/knowledge than for caregiver burden and depression. Psychoeducational and psychotherapeutic interventions showed the most consistent short-term effects on all outcome measures. Intervention effects for dementia caregivers were smaller than those for other groups. The number of sessions, the setting, care receiver age, caregiver age, gender, type of caregiver-care receiver relationship (spouse vs adult child), initial burden, and study characteristics moderated the observed effects.

Caregiver interventions are effective, but some interventions have primarily domain-specific effects rather than global effects. The differences between intervention types and moderators suggest ways of optimizing interventions.
