Association between familism and mental health in dementia caregivers: a systematic review and meta-analysis.

Background: Dementia caregivers suffer from mental health problems while caring for dementia patients. As a core value, familism has been linked to the mental health of dementia caregivers. This study aims to systematically review the familism of dementia caregivers and to examine the association between familism and mental health of anxiety, depression, and burden in empirical research studies.

Methods: We conducted a systematic search in various databases like Medline, PubMed, and Embase databases from inception till April 2021. Fisher's z was calculated with correlation coefficient or regression coefficient values for three familism dimensions and mental health of anxiety, depression, and burden. All statistical analyses were performed using Comprehensive Meta-Analysis (CMA) version 2.0 software.

Results: A total of seven studies with 1178 participants were eligible for the meta-analysis. For caregivers' anxiety, three of seven studies, with 358 participants, were examined in terms of the average corrected correlation coefficient across the studies. It was found that dementia caregivers' familism was significantly related to anxiety. The pooled z-value was 0.148 (95% CI = 0.043-0.253). In addition, caregivers' familism significantly affected depression (z = 0.080; 95% CI = 0.003-0.156), as did familial obligation (z = 0.122; 95% CI = 0.034-0.211), but perceived family support was not associated with this (z = 0.051, 95% CI = -0.038-0.140). As for caregiver burden, there was no evidence that familism was significantly associated with it (z = -0.073; 95% CI = -0.297 to 0.151), including familial obligation and perceived family support (z = -0.087 and -0.089, respectively; 95% CI = -0.278 to 0.104 and -0.335 to 0.157, respectively).

Conclusions: An association between caregiver familism and anxiety/depression exists in dementia patients. More research is needed to explore the relationship between familism and burden.
