Psychometric Properties of Shopping Addiction Scale in Iranian Sample

Shopping addiction is an uncontrollable need that forces a person to go shopping for temporary relief from psychological distress and depression. In this regard, the present study was conducted to investigate the reliability and validity of the shopping addiction scale in the Iranian sample. This research was a descriptive-analytical study of evaluation type. The sample consisted of 500 women (404) and men (96) in Tehran in 2021 who were selected by the available sampling method and completed the shopping addiction scale, saving inventory, and psychological well-being scale. Psychometric properties of the shopping addiction scale were analyzed by confirmatory factor analysis, divergent validity, concurrent validity, Pearson correlation, and Cronbach's alpha coefficient in R software version 4.1 at a significance level of 0.05. The seven-factor structure (Salience, Mood Modification, Conflict, Tolerance, Relapse, Withdrawal, and Problems) of the shopping addiction scale was evaluated and confirmed using confirmatory factor analysis (CFI = 0.89, RMSEA = 0.07). In examining the concurrent and divergent criterion validity, the correlation of the online shopping addiction scale with the saving inventory was positive and significant. The relationship between shopping addiction and psychological well-being was also negative and significant. Cronbach's alpha coefficient for the total score of the in-person addiction scale was 0.96 and for its dimensions was 0.81 to 0.92. The findings indicate the structural validity and acceptable reliability of the shopping addiction scale, and the multidimensional structure of this scale can help to diagnose shopping addiction.
