Internet usage among the oldest-old: does functional health moderate the relationship between internet usage and autonomy?

In recent years, research on internet usage in old age and its associations with well-being outcomes has increased. However, the oldest-old age group (80 years and older) is frequently underrepresented, and autonomy and functional health are rarely considered in these studies. By applying moderation analyses with a representative dataset of the oldest-old in Germany (N = 1863), our study has analyzed the hypothesis that the autonomy of older individuals, in particular of those with limited functional health, can be enhanced by internet usage. The moderation analyses indicate that the positive association between internet usage and autonomy is greater for older individuals with lower functional health. This association remained significant after controlling for social support, housing situation, education, gender, and age. Explanations for these results are discussed, and imply that further research is needed to understand the relationships between internet usage, functional health, and autonomy.
