Layers of loneliness: A qualitative study on social isolation in midlife using ecological systems theory

This study proposes policy measures to address social isolation among middle-aged individuals through ecological systems theory. In-depth interviews with eight high-risk participants were analyzed using framework analysis, a structured form of thematic analysis, in which inductively and deductively generated themes were organized into a systematic framework to integrate detailed data description with higher-level abstraction. The findings move beyond previous research that primarily emphasized individuals’ feelings of loneliness and psychosocial support, by applying an ecological systems perspective to address social isolation among middle-aged adults in a comprehensive and structural manner. The findings yield theoretical, practice, and research implications, informing multi-level interventions.
