Positive Social Interaction by Spatial Design: A Systematic Review of Empirical Literature in Memory Care Facilities...

Objective: The objective of this review is to outline a comprehensive set of possible design interventions focusing on spatial and environmental design factors influencing positive social interaction, which is one of the key aspects of quality of life (QoL) in long-term care facilities (LTCFs). Methods: This systematic literature review synthesized research evidence from seven databases (after the year 2000) spanning medical and health literature, environmental psychology, architecture, interior design, and evidence-based design literature. Results: The key spatial design characteristics of the facilities shown to affect positive social interaction were as follows: (a) The Physical Environment and Setting; (b) Accessibility, Legibility, and Layout; (c) Social Environment and Network; and (d) Staff-Resident Ratio and Care Philosophy. Conclusion: Several critical spatial design features of the facilities were identified. Spatial design interventions could influence the design decisions for future care facilities and provide designers the guidelines that are generalizable regardless of geographic location of the LTCF.
