Methods: An electronic survey based on Readiness and Enablement Index for Health Technology (READHY) was aimed at young adults in the geographical are of one wellbeing services county in Southern Finland. Data were analyzed using non-parametrical statistical methods. Results: Young adults ( N = 110) actively used eHealth and eWelfare and assessed themselves as having good general digital skills. They were confident in their eHealth literacy and readiness for the use of eHealth and eWelfare. However, young adults not in education, employment, or training (NEETs, n = 21) were significantly less confident than non-NEETs ( n = 89) in three of the five domains describing eHealth literacy, and readiness for the use of health technology.
