Methods: TThe study included 242 participants, including 97 young adults, 72 middle-aged adults, and 73 older adults, with an even distribution of age groups. The data were analyzed using SPSS version 27.0, employing descriptive statistics, the Fisher-Freeman-Halton exact test, one-way analysis of variance, the Scheffe test, and multiple linear regression analysis. Results: COVID-19 anxiety syndrome (\u03b2 = .28, p = .009) was found to be a significant factor influencing hypochondriasis among young adults, but this model was found to have no statistically significant explanatory power; COVID-19 anxiety syndrome (\u03b2 = .47, p &lt; .001), and searching as a component of digital health literacy (\u03b2 = \u2212.42, p = .018) were significant factors among middle-aged adults (29% explanatory power; F = 3.12, p = .001); and COVID-19 anxiety syndrome (\u03b2 = .40, p &lt; .001) and diagnosis of chronic disease (\u03b2 = .32, p = .006) were significant factors among older adults (24% explanatory power; F = 2.58, p = .006). Conclusion: Measures to reduce COVID-19 anxiety syndrome in adults of all ages are needed to manage COVID-19-provoked hypochondriasis. In particular, differentiated strategies to improve COVID-19-provoked hypochondriasis according to age groups need to be developed, taking into account searching as a component of digital health literacy among middle-aged adults and diagnosis of a chronic disease among older adults.<\/jats:p>","DOI":"10.7586\/jkbns.25.017","type":"journal-article","created":{"date-parts":[[2025,8,14]],"date-time":"2025-08-14T04:42:30Z","timestamp":1755146550000},"page":"387-399","update-policy":"https:\/\/doi.org\/10.7586\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Age-differentiated
