The aim of this study was to develop a self-administering scale that could measure smartphone use. In addition, the reliability and validity of the Smartphone Use Scale (SUS) was demonstrated. A set of 30 questions pertaining to smartphone use were developed with the help of experts. A total of 372 participants were selected to accomplish a set of questionnaires –Smartphone Use Scale (SUS) and Smartphone Addiction Scale (SAS) (Kwon, Lee, Won, Park, & Min, 2013). The sample comprised 182 males and 190 females, with ages ranging from 16 to 22. Internal-consistency test and correlation analysis were conducted to verify the reliability and validity of SUS. Reliability and concurrent validity of the test were computed. Cronbach’s alpha was found to be 0.712. Concurrent validity using the SAS was found to be 0.76. The study shows that 13.72% males and 14.28% females fall under the “high smartphone use” category, 63.72% males and 63.47% females were found to be under the “average smartphone use category, and 22.54% males and 21.73% females were found to be under the “low smartphone use” category.
