The Role of Digital Literacy in Moderating Mental Health Outcomes among the Elderly: A Comprehensive Analysis

Abstract

This paper examines the critical and evolving role of digital literacy as a moderator of mental health outcomes among older adults. In an era of rapid digitalization, the ability to use information and communication technologies (ICT) has become a significant determinant of psychosocial well-being in later life. Drawing upon interdisciplinary research from gerontology, psychology, public health, and communication studies, this analysis synthesizes empirical evidence demonstrating that digital literacy functions as both a protective factor against depression, loneliness, and social isolation, and a potential risk factor when absent. The paper elaborates on theoretical frameworks including digital divide theory, social capital theory, social cognitive theory, socioemotional selectivity theory, and person-environment fit models to elucidate the mechanisms through which digital skills influence mental health. Methodological considerations in existing research are critically assessed, highlighting the need for longitudinal, mixed-methods designs and standardized measures. The review confirms a consistent moderating effect, whereby digital literacy buffers the impact of traditional risk factors, particularly for socially isolated or economically disadvantaged elders.
