Online Administration and Psychometric Characteristics of the Croatian Version of the 7C Vaccination Readiness Scale and The Attitudes Against Socializing With (Non-)Vaccinees Scale

The Croatian version of 7C vaccination readiness scale and the new Attitudes Against Socializing with (Non-) Vaccinees Scale have been applied online. The aim of this study was to explore their psychometric properties and whether online application is justified. The study involved 1806 participants (76.3% female) with an average age of 35.95 years (SD = 11.66). In order to examine the psychometric characteristics of the 7C vaccination readiness scale, a confirmatory factor analysis was conducted with the assumption of a bifactor model. Based on the modification indices, the final model suggests the measurement error covariances for the first two Complacency items, which both address the need for vaccination, and for the first and third Compliance items, which both address the need to punish non-vaccinees. This final model has a satisfactory fit (χ2 = 1728.24 ; p < .001 ; GFI = 0.910 ; CFI = 0.958 ; TLI = 0.951 ; RMSEA = 0.069 (0.066-0.072)). The reliabilities of the factors are satisfactory (.73 to .97) with the exception of the reliability for the Calculation (.60), which will be further commented on in the paper. An exploratory factor analysis was performed for the Attitudes Against Socializing with (Non-)Vaccinees Scale, which had 13 items in its original form. The analysis suggested a version with 11 items distributed in Attitudes against socializing with non-vaccinees (eight items ; α = .93) and Attitudes against socializing with vaccinees (three items, α = .70) and explained 66.89% of the variance. The data suggest satisfactory psychometric characteristics of these scales and the appropriateness of their online application. The challenging items and the possibilities of eliminating these challenges will be discussed thouroughly
