Exploring Intergenerational Interactions in Residential Environments: A Systematic Scoping Review.

Abstract

Background: Family caregiving has been central to U.S. eldercare, supported by federal policies. However, recent shifts towards neoliberalism, devolution of aging policy, rising chronic illnesses, and increasing social isolation have spurred interest in intergenerational communities. Objective: This study explores these models, assessing their impact on health and well-being. Methods: We conducted a systematic scoping review of studies published after 2000, searching PsycInfo, Family & Society Studies Worldwide, SocINDEX, Urban Studies, PubMed, Scopus, and Web of Science. Results: Selected studies were analyzed under three themes: the quality and quantity of intergenerational interactions, potential benefits, and the impact of the built environment. A total of 20 studies were included in this review. Interventions mostly occurred weekly, with varied interaction quality. Potential outcomes included improved intergenerational attitudes, social and behavioral development, physical and mental health, and quality of life. Research on the role of the built environment remains scarce. Conclusion: This review highlights the potential of Intentional Intergenerational Communities (IICs). However, significant gaps remain, reflecting the early stage of IIC implementation. Future research should focus on generating robust evidence to inform policymakers and practitioners.
