AB - Cross-sectional and longitudinal associations were examined for social isolation, loneliness, and self-control in 299 Korean adults (aged 40–83 years) across three waves over one year.
At baseline, self-control partially mediated and moderated the isolation–loneliness link.
Loneliness increased over time, with higher baseline social isolation predicting a greater increase. However, self-control did not predict longitudinal changes in loneliness.
Middle-aged adults reported higher isolation and loneliness and lower self-control than older adults. Mediation was significant only for middle-aged adults, whereas longitudinal effects were observed in both groups. Overall, social isolation longitudinally exacerbates loneliness, and the moderating effect of self-control is cross-sectional. Effective interventions may need to address both short-term self-control and long-term social isolation, extending beyond older adults to include middle-aged adults.
