Background: This study aimed to identify the predictors of the intention to receive the COVID-19 vaccine among Iranian health care workers (HCWs) based on the Theory of Planned Behavior (TPB). Methods: The study was a descriptive cross-sectional study that was conducted on 473 personnel working in hospitals of Hamadan, in May 2021 and before COVID-19 vaccination on hospital staff. The multi-stage sampling method was used for choosing participants. The survey included socio-demographic, questions related to TPB dimensions, and intention to receive a COVID-19 vaccine. Qualitative and quantitative data analyses were performed using the Chi-square test and T-test, respectively. Predictors of COVID-19 vaccination intention were determined using the logistic regression model. Results: Seventy percent of 361 eligible respondents stated their willingness to receive COVID-19 vaccine. The participants with the intention to receive COVID-19 vaccine had higher scores of attitude (7.25 ± 3.92 vs. 4.40 ± 5.14) and norm (3.04 ± 2.92 vs. -0.5 ± 3.18) (P < 0.001). Having an underlying disease and being married were significantly associated with the intention to receive COVID-19 vaccine (P < 0.05). Higher attitude and norm scores as a construct of the TPB were associated with an increase in intention to receive COVID-19 vaccine. Conclusions: The results of this study showed that the vaccination intention was affected by social, demographic, health, and behavioral features, such as age, marital status, underlying diseases, subjective norms, and attitude. Therefore, age groups below 50, single people, and those with no underlying diseases were eligible to be the target of interventional programs.
