| Abstract
The Smartphone Application-Based Addiction Scale (SABAS) can be used in screening for
the risk of smartphone addiction. This study aimed to validate a Persian version of the SABAS
using confirmatory factor analysis (CFA), Rasch analysis, and latent class analysis (LCA). In a
sample of 3807 Iranian adolescents, CFAs were used to confirm the factor structure of
SABAS, Rasch models were used to examine the unidimensionality of SABAS, and LCAs
were used to classify the adolescents in terms of application preferences and smartphone
application-based addiction. The unidimensional structure of SABAS was supported by CFA
and Rasch model. LCA classified the sample into three subgroups (i.e., low, medium, high) in
terms of risk of smartphone addiction. This study showed the unidimensionality of the Persian
SABAS with robust psychometric properties. It can be used by healthcare providers in
screening for risk of addiction to smartphone applications and provide early intervention if
necessary. |
