Smartphone addiction among adolescents has become a major concern. The present study aims to investigate the psychometric properties of the Persian Smartphone Addiction Scale - Short Version (SAS-SV). A sample of 398 adolescents (52% girls and 48% boys) completed the SAS-SV, the Kutcher Adolescent Depression Scale (KADS), and the Young Internet Addiction Test (IAT). Factor analysis showed that the Persian SAS-SV consisted of one factor and is a reliable (Cronbach's [alpha]=?0.82) and valid (CFA model fit: RMSEA?=?0.7, CFI?=0?.95, AGFI?=0?.92) measure. Strong correlations with depressive symptoms (r?=?0.41) and internet addiction scores (r?=?0.57) were also found. A high prevalence of smartphone addiction in adolescents and the correlation with depression and internet addiction signals that more attention should be given to this issue. The Persian SAS-SV is a valid and reliable scale to be used for Persian speaking samples.
