Turkish Adaptation, Validity and Reliability of the Online Shopping Addiction Scale (OSAS-TR)

Abstract

Objective: This study aimed to determine the validity and reliability of the Turkish version of the ''Online Shopping Addiction Scale'' (OSAS-TR).Method: It is a methodological type of research. A back-translation technique was used and then the scale was validated with a sample of 275 young adults. The translation of the scale into Turkish was done according to the forward and reverse conversion procedure. The test-retest method, Cronbach's alpha coefficient, Split-half analysis, and item analysis methods were used to determine the reliability of the scale. Running to determine construct validity factor analyses were applied. The Turkish version of Online Shopping Addiction Scale (OSAS-TR) and the Young Internet Addiction Scale (YIAS) were applied to the all participants. SPSS 23.0 package program was used for the analysis of the data. Results: The mean age of the participants was 22.2±1.9 years. The mean OSAS-TR score of the participants was 32.1±12.1. Women's OSAS-TR scores were significantly higher than men's scores (p<0.05). There was a statistically significant positive correlation between the mean scores of the YIAS and OSAS-TR scores (p<0.05). Cronbach's alpha coefficient was measured as 0.899. Spearman-Brown coefficient was 0.85 and the Guttman Split-Half coefficient was 0.81. The Kaiser-Meyer-Olkin coefficient was 0.926 and the Barlett Sphericity test was p<0.001, and the data were found to be suitable for factor analysis. The three-factor structure consisting of 18 items explained 67.57% of the total variance. According to the item-total correlation and Cronbach's alpha values when the item was deleted, no item was deleted from the scale. Conclusions: OSAS-TR is a valid and reliable tool for measuring and addressing online shopping addiction in young adults. After comprehensive analyses, it was determined that the scale's measurement skill, internal consistency, and temporal consistency were sufficient.
