Abstract
The coming decades will see a substantial increase in the population of older adults, accompanied by significant demographic and family structure changes worldwide. As a result, the empty nest period-the postparental phase in parents' lives when their children have left home and they are no longer engaged in childrearing-is becoming an increasingly common experience in Western and Asian cultures. The current theoretical review examines the psychological consequences of the empty nest period on loneliness and well-being across cultures, emphasizing the impact of cultural factors on these experiences. By synthesizing research from Western and Asian contexts, we explore two primary theoretical mechanisms-role loss and role strain relief-that shape the postparental phase's psychological outcomes. Our review reveals that while some parents experience reduced well-being due to role loss, others benefit from role strain relief and increased social engagement. We highlight how cultural differences in familial roles, gender roles, social expectations regarding nest-leaving, and social participation patterns moderate these mechanisms. We propose a comprehensive cultural framework, along with a discussion of culturally sensitive interventions to enhance the well-being of empty nesters globally.
