Health-related difficulty in internet use among older adults: Correlates and mediation of its association with quality of life through social support networks.

BACKGROUND AND OBJECTIVES Internet use is increasingly a necessity. However, older adults may not use the internet due to either non-health reasons (e.g., lack of digital literacy or internet access) or health-related reasons (e.g., visual impairment or movement difficulties). While researchers have studied internet use among older adults, most do not discriminate whether non-use is due to health-related reasons or otherwise. We therefore examine the key correlates of health-related difficulty in internet use among older adults, and how it may affect quality of life (QoL) through their perceived social support networks. RESEARCH DESIGN AND METHODS Data were from a national survey of older Singaporeans (N=3966) conducted in 2016-17. Multinomial logistic regression and mediation analysis were used to identify older adult subgroups more likely to experience health-related difficulty in internet use, and whether such difficulty affected older adults' QoL through their social support networks. RESULTS Those of male gender, of Malay ethnicity, with less education, and with more instrumental activity of daily living limitations were more likely to experience health-related difficulty in internet use. Social support networks mediated the relationship between health-related difficulty in internet use and QoL. DISCUSSION AND IMPLICATIONS Disparities in internet use are not just shaped by access or skill, but also health. Health-related difficulties in internet use are related to older adults' social support networks and quality of life. As social connections become increasingly based around networked individuals due to technological advancements, more attention should be given to addressing these health-related difficulties.
