2.5. eHealth Literacy

eHealth literacy is defined as the “ability to seek, find, understand, and appraise health information from electronic sources and apply the knowledge gained to addressing or solving a health problem” [32] Participants’ skill of looking for electronic health resources was measured with the eHealth literacy scale (eHEALS) [32]. The formal part of this instrument consists of eight items. Additionally, the scale developers have incorporated two supplementary items to measure people’s general interest in eHealth. Responses were recorded on a 5-point scale (1 = strongly disagree; 5 = strongly agree). The total score ranged from 16 to 50. A higher score meant a higher eHealth literacy. This instrument’s internal consistency was excellent, with a Cronbach alpha score of 0.90 [31].
