Types of smartphone usage and relations with problematic smartphone behaviors: The role of content consumption vs. social smartphone use

“…We should note that prior research often has assessed smartphone use as the predictor variable(s) and problematic use as the dependent variable(s) Park et al, 2013;van Deursen et al, 2015). In the present paper, we used the reverse ordering of variables.…”

“…UGT has been applied to understanding problematic internet use (e.g., Kim & Haridakis, 2009;Song et al, 2004), and more recently to problematic smartphone use (Dhir et al, 2015;Park, Kim, Shon, & Shim, 2013) by examining individual differences accounting for problematic use. Applying UGT within the context of problem smartphone use, individuals' problem smartphone behaviors may vary as a function of the particular types of smartphone uses they prefer (Park et al, 2013). Kardefelt-Winther's (2014) recently-developed Compensatory Internet Use Theory (CIUT) could be viewed as an extension of UGT, in explaining variables that drive such use.…”
