Abstract
BACKGROUND AND
PURPOSE: The negative attitude towards vaccines for coronavirus disease (COVID-19) has motivated the adaptation of instruments for this specific purpose. However, details of the reliability and validity of these scales are unknown. The study aimed to evaluate some indicators of the reliability and validity of the Spanish version of the Attitude towards COVID-19 Vaccines Scale.
METHODS: A validation study was carried out with 1,136 students of emerging age (18 and 29 years) from a Colombian university; 65.5% were female. Cronbach's alpha and McDonald's omega were calculated for reliability, and exploratory and confirmatory factor analyzes for validity. Additionally, the gender differential item functioning (DIF) was estimated with Kendall's tau b.
RESULTS: The Spanish version of Attitude towards COVID-19 Vaccines Scale showed high internal consistency (Cronbach's alpha of .94 and McDonald's omega of .95), a one-dimensional structure with acceptable goodness-of-fit indicators (CFI = .94, TLI = .91, and SRMR = .04), and non-gender DIF (Kendall's tau b between .02 and .06).
CONCLUSIONS: The Spanish version of the Attitude towards COVID-19 Vaccines Scale presents some appropriate reliability and validity indicators among university emerging adults. These findings should be explored in samples with other characteristics. © Copyright 2022 Springer Publishing Company, LLC.
