Turkish Validity and Reliability Study of the Digital Vaccine Literacy Scale

Objectives: This study aimed to assess the validity and reliability of the Turkish version of the Digital Vaccine Literacy (DVL) scale. Methods: This methodological study was conducted with 236 staff working at a foundation university hospital between September 2023 and April 2024. Data were collected using the Personal Information Form and DVL scale. The linguistic validity, content validity, exploratory factor analysis, and confirmatory factor analysis of the scale were conducted. Reliability was evaluated through item-total correlations, Cronbach's alpha coefficient, and test-retest reliability. Data were analyzed in SPSS 27.0 and AMOS 22.0 package programs. Results: The study revealed 3 dimensions comprising 7 items, with factor loadings ranging from 0.612 to 0.851, explaining 78.63% of the total variance. The fit measures were acceptable (χ2/df = 3.271; RMSEA = 0.072; CFI = 0.912; NFI = 0.875; GFI = 0.874; TLI = 0.889; IFI = 0.876; p < 0.001) in confirmatory factor analysis. The overall Cronbach's alpha value of the scale was 0.730, while the sub-dimensions were 0.791, 0.891 and 0.781, respectively. The test-retest reliability correlation was positive, very strong and statistically significant (r=0.962, p
