Analysis of the impact of digital literacy on life satisfaction (2019-2022) for older adults in South Korea: a national community-based panel study.

This study analyzed the effects of digital literacy on life satisfaction in older adults aged 65 years and above in modern day Korea. It utilized raw data from the 2019-2022 Report on the Digital Divide, an annual survey conducted by the Korean Ministry of Science and Information and Communications Technology. A total of 4,216 participants were assessed from 2019-2022. Correlation between digital literacy and life satisfaction was analyzed using Pearson correlation analysis and polynomial linear regression analysis. Life satisfaction was significantly positively correlated with digital access, digital competency, and digital utilization in all the years. In 2019, participants' life satisfaction score rose significantly by 0.15 with every one-point increase in digital competency. It further rose by 0.035 in 2020, 0.030 in 2021, and 0.116 in 2022. Digital literacy was consistently positively correlated with life satisfaction in each year from 2019-2022. Of the three main elements, digital competency had the strongest impact and digital information, income, and education level also significantly impacted life satisfaction. While digital competency improved steadily from 2019 to 2022, it remains below 50% for Korea's older adult population. Further efforts are required to improve digital competency and subsequent life satisfaction among Korea's older adult population.
