ABSTRACT
OBJECTIVES:
To examine the longer-term effects of benefit-finding on caregivers' depressive symptoms (primary outcome), and global burden, role overload, psychological well-being, and positive aspects of caregiving (secondary outcomes).METHOD:
Ninety-six Hong Kong Chinese caregivers of relatives with Alzheimer's disease were randomly assigned to receive the benefit-finding intervention (BFT) or one of the two control conditions, namely, simplified psychoeducation (lectures only; SIM-PE) or standard psychoeducation (STD-PE). Caregivers received four biweekly one-to-one interventions of 3 hours each at their own homes. We focused on outcomes measured at 4- and 10-month follow-ups. The trajectories of intervention effects were modeled by BFT × time and BFT × time2 interaction terms.RESULTS:
Mixed-effects regression showed significant BFT × time2 interaction effects on depressive symptoms against both control conditions, suggesting diminishing BFT effects over time. Z tests showed that, compared with controls, BFT participants reported substantial reductions in depressive symptoms at 4-month follow-up (d = -0.85 and -0.75 vs. SIM-PE and STD-PE, respectively). For depressive symptoms measured at 10-month follow-up, BFT was indistinguishable from STD-PE, whereas a moderate effect was observed in comparison with SIM-PE (d = -0.52). Moreover, positive aspects of caregiving, but not other secondary outcomes, continued to show intervention effect up to 10-month follow-up.DISCUSSION:
Benefit-finding is an efficacious intervention for depressive symptoms in Alzheimer caregivers, with strong effects in the medium-term post-intervention and possible moderate effects in the longer-term post-intervention.Palabras clave
