“…Recent studies corroborate the existence of WaP as a distinct dimension of burden among adult children caregivers, which may be particularly salient in Asian societies that are often heavily influenced by notions of filial piety and obligatory care (Cheah et al, 2012). Unlike role and personal strain, WaP is poorly correlated with other factor scores, significantly endorsed even in milder stages of cognitive impairment and is not predicted by "conventional" factors such as functional impairment and behavioral problems (Lim et al, 2014). In support of this, a recent confirmatory factor analysis revealed that ZBI factor models premised on the three key dimensions of role strain, personal strain, and WaP were superior to one-factor (total score) and two-factor (role/personal strain) models (Li et al, 2018).…”
