The relationship between filial piety and caregiver burden among adult children: A systematic review and meta-analysis

Filial piety is an important cultural value in aging societies. However, mixed findings were identified regarding its influence on caregiver burden. The purpose of this meta-analysis was to clarify the relationships between filial concepts and caregiver burden. Twelve databases on filial piety, filial obligation, and caregiver burden among adult children prior to January, 2020 were systematically cross-culturally reviewed. Twelve studies were finalized for analysis. Fixed effect models indicated that stronger filial piety was significantly correlated (r = −.23) or associated with (β = −.27) less caregiver burden. However, no significant relationship between filial obligation and caregiver burden was revealed by random effect models. Stronger filial piety may lessen caregiver burden. Therefore, filial piety should be assessed and supported in adult child caregivers, particularly in Eastern cultures. However, the concept of filial piety and its tools should be updated transculturally. PROSPERO Registration Number: CRD42020161969
