“…Older users primarily use SNSs to maintain their relationship with close contacts (i.e., friends and family) and overall spend less time on the site (e.g., Brandtzaeg, Lüders, & Skjetne, 2010;Christofides, Muise, & Desmarais, 2012;McAndrew & Jeong, 2012), whereas younger adults seek larger and more heterogeneous social networks and use SNSs for a wider range of purposes (Arjan, Pfeil, & Zaphiris, 2008;Chang et al, 2015). Being at a developmental stage characterized by "exploration and instability" (Arnett, 2004), young adults are more likely to be motivated to experiment with social boundaries and engage in self-disclosure on SNSs as a means of satisfying this motivation than older adults do (for a summary, see Van den Broeck et al, 2015). Relatedly, young adults are more likely to use SNSs for self-presentation, which, in turn, may be related to their tendency to use SNSs more actively, which entails higher self-disclosure (Arjan et al, 2008;Chang et al, 2015;Christofides et al, 2012;Peter & Valkenburg, 2011;Steijn, 2014;Walrave et al, 2012).…”
