Abstract
The present study applied the Transtheoretical Model (TTM) to better understand readiness, including decisional balance (DCBL; pros and cons) and self-efficacy (SE), as well as myths and barriers for COVID-19 vaccination. Using existing TTM-, COVID-19-, and vaccination-related literature, definitions for each Stage of Change (SOC) and measurement items for each DCBL, SE, Myths, and Barriers scales were developed. 528 adults ages 18 to 75 completed an online questionnaire containing the scales. For DCBL, exploratory factor analysis/principle component analysis (EFA/PCA) revealed three correlated factors (one pros, two cons) (n1 = 8, α = .97; n2 = 5, α = .93; n3 = 4, α = .84). For SE, two correlated factors were revealed (n4 = 12, α = .96; n2 = 3, α = .89). Single-factor solutions for Myths (n = 13, α = .94) and Barriers (n = 6, α = .82) were revealed. CFA confirmed models from EFAs/PCAs. Follow-up analyses of variance aligned with past theoretical predictions of the relationships between SOC, pros, cons, and SE, and the predicted relationships with myths and barriers. This study produced reliable and valid measures of TTM constructs for readiness to receive COVID-19 vaccination that can be used in future research.
