Abstract:

In this study, we aimed to determine the validity and reliability of the Smartphone Addiction Inventory-Short Form (SPAI-SF) developed by Lin et al. for Turkish high school students. We analyzed the construct validity by conducting a confirmatory factor analysis (CFA) with the data collected from 578 participants who used smartphones in the past 3 months. Young’s Internet Addiction Test-Short Form was used for criterion validity. We calculated the Cronbach’s alpha coefficient for the internal consistency of the scale. We conducted the test-retest reliability of the scale with 109 students. We used item analysis based on the correlations method. As a result of CFA, x2/df=2.25, root mean square error of approximation=0.047, comparative fit index =0.98, normed fit index=0.96, and incremental fit index=0.98. We found a highly positive and significant relationship between total scores of the two scales (r=0.57, p<0.001). The Cronbach’s alpha value was 0.85 in the internal consistency analysis. First and retest total scores were highly positively correlated (r=0.68, p<0.001). In the item analysis based on correlations, the Spearman correlation coefficients calculated for each item ranged from 0.47 to 0.70 (p<0.001). SPAI-SF can be used as a measurement tool to evaluate the risk of smartphone addiction in Turkish high school students.
