“…Traditional theoretical models have examined psychopathology predicting increased smartphone use frequency, which in turn predicts problematic smartphone use Kim, Seo, & David, 2015;van Deursen et al, 2015). This model assumes that psychopathology lends itself to increase smartphone use, which in turn can grow into problematic use, a notion that fits with UGT (Blumler, 1979) and CIUT (Kardefelt-Winther, 2014). However, such models have rarely measured smartphone use frequency or problematic use in a multidimensional manner (using subscales), and future work could benefit from such a richer multidimensional approach.…”
