“…PSU is typically assessed with various scales, including the Mobile Phone Problem Use Scale (MPPUS; Bianchi & Phillips, 2005 ), the Problematic Mobile Phone Use Questionnaire (PMPUQ; Billieux, der Linden, & Rochat, 2008 ), the Smartphone Addiction Scale (SAS; Kwon, Lee, et al., 2013 ), the Short Version of Smartphone Addiction Scale (SAS-SV; Kwon, Kim, Cho, & Yang, 2013 ), the Smartphone Addiction Inventory (SPAI; Lin et al., 2014 ) and the Short-Form of Smartphone Addiction Inventory (SPAI-SF; Lin, Pan, Lin, & Chen, 2017 ), which measure factors like tolerance, withdrawal, overuse, loss of control and dangerous/prohibited use. While cross-cultural validation studies have shown satisfactory psychometric properties for these scales (e.g., Agus, Mascia, Bonfiglio, & Penna, 2022 ; Andrade et al., 2022 ; Khoury et al., 2017 ; Lopez-Fernandez, Honrubia-Serrano, Freixa-Blanxart, & Gibson, 2014 , 2018 ; Sfendla et al., 2018 ; Wang, Long, Liu, Liu, & Billieux, 2020 ; Zhao, Rafik-Galea, Fitriana, & Song, 2022 ), we would argue that there is room for improvement.…”
