Turkish validity and reliability study of the falsified hand sanitizer identification scale

Abstract

Objective: The aim of this study was to analyze the validity and reliability of the Fake Hand Sanitizer Identification Scale, which was developed to help consumers determine safe and effective hand disinfectants, in Turkish culture and language. Methods: This methodological and cross-sectional study was conducted between February and April 2021 by applying an online questionnaire to a state university staff. 355 people were reached. The Turkish validity of the scale was tested with language (translation-back translation), structure (Confirmatory Factor Analysis (CFA)) and known group validity. Reliability was evaluated with Cronbach's alpha internal consistency coefficient, item analysis based on item-total correlation, and test-retest method (Spearman correlation analysis). Results: Majority of the participants (62.18%, n=217) were male, and the mean age of all participants was 41.14 ± 9.80 years. In DFA, x2/sd = 3.67, CFI = 0.98, GFI = 0.92, NFI = 0.97, and RMSEA = 0.08. As the frequency of daily use of sanitizer increased, the score obtained from the scale increased (p < 0.001). When all items were removed from the scale, the Cronbach's alpha value of the scale decreased. The Cronbach's alpha value of the scale was 0.934, 0.892 for factor 1, 0.891 for factor 2 and 0.818 for factor 3. The corrected item-total correlation values of all items ranged from 0.584 to 0.758. The test-retest correlation coefficient was 0.859 (p < 0.001). Conclusion: The Turkish Falsified Hand Sanitizer Identification Scale is a valid and reliable 5-point Likert scale consisting of 12 items and 3 sub-dimensions.
