“…Online health information is, however, often inaccurate, inappropriate, or not updated (Carpenter et al, 2011;Langille et al, 2010). The potential negative effect of using (inaccurate) online health information on public health-related behaviors has drawn research attention but this is still scarce and inconclusive (Carpenter et al, 2010;Carpenter, Elstad, Blalock, & DeVellis, 2014;Im & Huh, 2017;Sivakumar & Mares, 2016). A reason for these inconclusive results might be that the majority of existing studies are cross-sectional in nature and were thus only able to provide 'snapshots' of patients' online information seeking behavior measured at a single point in time (Bernstein et al, 2011;Lee, Hoti, Hughes, & Emmerton, 2014;Rutten, Arora, Bakos, Aziz, & Rowland, 2005;Squiers, Finney Rutten, Treiman, Bright, & Hesse, 2005).…”
