INTRODUCTION:
Knowledge Gap: Disparities in caregiver burden across racial/ethnic groups are well established, but the mechanisms driving these differences, especially the role of domain-specific self-efficacy, remain unclear.
Approach: This study examines whether perceived social support and domain-specific caregiving self-efficacy are associated with caregiver burden across racial/ethnic groups.
METHODS:
•Baseline data from an on-going clinical trial was examined (n=179)
Instruments:
•Multidimensional Scale of Perceived Social Support (MSPSS)
•Revised Scale for Caregiving Self-Efficacy (3 domains)
•Neuropsychiatric Inventory (Caregiver Burden)
MANOVA and post hoc analyses with Bonferroni adjustment were conducted.
RESULTS:
A multivariate analysis of variance revealed significant group differences in self-efficacy for obtaining respite (F(3,178) = 5.151, p = .002) and caregiver burden (F(3,178) = 5.324, p = .002). Post hoc analyses with Bonferroni adjustment indicated that Hispanic caregivers reported lower perceived social support (p = .048) and lower self-efficacy in obtaining respite (p = .002) compared to Black non-Hispanic caregivers, and higher caregiver burden compared to both Black (p = .001) and White non-Hispanic caregivers (p = .003). Black non-Hispanic caregivers demonstrated higher self-efficacy in obtaining respite compared to White non-Hispanic caregivers (p = .024). Regression analyses revealed that among Hispanic caregivers, self-efficacy in controlling upsetting thoughts was strongly associated with caregiver burden (β--.749, t = -3.56, p < .004), whereas among White non-Hispanic caregivers, perceived social support was significantly associated with burden (β = -.285, t = -3.274, p < .001
CONCLUSIONS:
•Self-efficacy and perceived social support may differentially influence caregiver burden across ethnic groups.
•Interventions aimed at reducing caregiver burden should consider culturally tailored strategies that enhance self-efficacy and social support.
