The purpose of this study is to examine the effectiveness of the interventions for improving mental health of caregivers of people with stroke by synthesizing individual studies. A meta-analysis was performed to summarize findings of intervention studies of caregivers of elderly stroke patients. Additionally, a sensitivity analysis and a publication bias were tested. The overall mean weighted effect size (MWES) for the four studies is 0.277 (Z = 3.432, p =.001) with a 95% CI.118 to.435 (N = 718) indicating that the intervention was effective in improving the mental health of informal stroke caregivers. The MWES for the education program was 0.354 (Z= 2.613, p <.01) and for the support program was.234 (Z = 2.335, p=.02). The MWES for the Europe study was.219 (Z= 2.613, p <.01) and for the United States was.922 (Z = 3.287, p =.001). The results show that overall interventions improved mental health of informal stroke caregivers. The small number of studies included in the meta-analysis limits the generalizability of results while supporting the need for more research in this area.
