Association of eHealth Use, Literacy, Informational Social Support, and Health-Promoting Behaviors: Mediation of Health Self-Efficacy.

This descriptive, cross-sectional study identified the association of eHealth use, literacy, informational support, and health-promoting behaviors among older adults, as mediated by health self-efficacy. Convenience sampling was conducted at senior welfare centers in Chuncheon, in the Republic of Korea. Data analysis was performed using Pearson's correlation and via path analyses. The findings showed that eHealth use had an indirect effect on health-promoting behaviors, as mediated by self-efficacy. Informational support was indirectly mediated by self-efficacy and had direct effects upon health-promoting behaviors. eHealth can facilitate self-efficacy and health management, despite not having direct effects upon health-promoting behaviors themselves. Thus, older adults need to be prepared for the increased use of eHealth. In addition, healthcare professionals should support older people in their use of eHealth and encourage informational support through comprehensive interventions so as to facilitate self-efficacy and health behaviors.
