A two-stage analysis of social media use patterns, psychosocial well-being, and frailty in an aging Japan

Social media usage patterns reflect underlying psychosocial states, but are not direct predictors of frailty. The motivation-driven behavior of self-documentation, rather than general activity, is a risk factor. These findings suggest that interventions should focus on the quality and function of social media use, promoting digital literacy that enhances well-being in older adults.
