Smartphone addiction (SAS-SV): Kwon et al. (2013)
The SAS-SV measures smartphone addiction through signs such as disruption of daily life, irritability without the phone, using it longer than intended and complaints from others. Kwon, Kim, Cho and Yang (2013) selected 10 items from the 33-item SAS based on expert ratings and validated them with Korean adolescents. It is the most widely used smartphone addiction scale in student theses, linked with sleep, stress, academic performance and FoMO.

Response scale
6-point Likert scale (1 = Strongly disagree … 6 = Strongly agree), following the original SAS from which the SAS-SV was derived. Summing the 10 items gives 10–60; there are no reverse-coded items. Kwon et al. (2013) proposed cut-offs of 31 for boys and 33 for girls among Korean adolescents.
