“…Fifty-six of the articles examined sources including the type of information source, the quality and if that source was personal, formal or informal (Campbell, 2009;Ghweeba et al, 2017;Gibson, 2016;Wonsun et al, 2015). Twenty-nine explored the type of health related information sought such as information about dermatology, smoking cessation or diabetes (Jung et al, 2011;Noh et al, 2016;Ramasamy et al, 2016), and 22 of them were mutually interested in sources used. Research dedicated either entirely to discrete actions, such as discussing the information with others, and active versus passive seeking habits (Davis, 2014;Gavgani et al, 2013), or these actions in conjunction with other means of operationalisation, made up 23 of the articles.…”
