Effect of support groups on caregiver's quality of life

The objective of this study was to evaluate the effect that participating in support groups for caregivers has on the quality of life and psychotropic drug use of family caregivers of adults with limitations in activities of daily living. A controlled quasi-experimental longitudinal design was used with 134 caregivers (64 in the experimental group and 70 in the control group). The outcomes were health-related quality of life (EuroQol 5D3L test) and psychotropic drug use (no/yes). The analyses were performed using SPSS and R statistical software. An interaction was observed between the condition and the level of limitations in activities of daily living of the care receiver, having an effect on the caregiver's psychotropic drug use (p = 0.003), with this use being lower among caregivers who attend support groups when their relatives present fewer limitations in activities of daily living. Moreover, the quality of life was higher in the post-test in the experimental group (B = 8.66, p = 0.015). In conclusion, support groups could improve the caregiver's quality of life and decrease psychotropic drug use when the care receiver has low limitations in activities of daily living.
