“…In order to study people's digital skills, researchers have started to develop digital literacy measures. However, currently existing measures have several limitations, such as not being up to date with the fast changes in technology (Wilson et al, 2015), having a narrow focus on the Internet at the omission of other technological developments (Hargittai & Hsieh, 2012;Lee & Chae, 2012;Len-Ríos, Hughes, McKee, & Young, 2016;Tsai & Tsai, 2010) or not having been validated (Pino Juste & Soto Carballo, 2010;Gastelú, Kiss, & Domínguez, 2015;Li & Ranieri, 2010;Park & Burford, 2013). Others have been validated only among children, adults or young adults, but not among adolescents (Boyaci & Atalay, 2016;Bunz et al, 2007;Helsper & Eynon, 2013;Koc & Barut, 2016;Park & Burford, 2013;Røkenes & Krumsvik, 2016).…”
