How Internet Control Beliefs and Involvement Shape Older Adults’ Social Adaptation Through Differential Internet Use

ABSTRACT: In an increasingly digitalized society, successful aging requires effective social adaptation through Internet engagement, yet empirical evidence on how specific online behaviors affect older adults’ adaptation remains limited. Grounded in the Theory of Planned Behavior, this study examines the associations between four Internet use types—informational, social, instrumental, and recreational—and social adaptation, and their mediating roles between psychosocial antecedents (Internet control beliefs and involvement) and adaptation outcomes. Using data from 388 Chinese older adults (aged 60–83), structural equation modeling revealed that only instrumental and recreational use showed significant positive associations with social adaptation, whereas informational and social use showed no substantial effects. Internet control beliefs and involvement predicted all four usage types, with their effects on adaptation fully mediated by instrumental and recreational activities. By elucidating these domain-specific pathways, the findings refine the application of the Theory of Planned Behavior to digital engagement in aging populations. Accordingly, interventions aimed at enhancing digital inclusion and adaptive aging may benefit from promoting instrumental and recreational Internet use while supporting older adults’ perceived control and active involvement in the digital environment.
