Background: Vaccination against Covid-19 is a crucial tool to combat the disease and control the pandemic. In Italy, despite the initial success of the vaccination campaign, vaccination rates are still not optimal in some population groups, as well as adherence to booster doses. To clarify whether and how vaccination acceptability has changed over time, this repeated cross-sectional study aimed to test the efficacy of an extended Theory of Planned Behaviour (TPB) model (including anticipated affects, risk perception, trust in science, trust in government, and religiosity) in predicting intention to get vaccinated in three different stages of the pandemic. Methods: Three self-report questionnaires were administered to three different convenience samples of Italian adults: at T1 (November 2020; N = 657), we evaluated intention to receive the future vaccine against Covid-19; at T2 (April 2021; N = 818), we measured actual vaccination intention; at T3 (February 2022; N = 605), we evaluated intention to continue vaccinating. Findings: Results from ANCOVAs indicated significant differences between the time points in all investigated variables, highlighting that vaccination acceptability was higher at T2 than T1, and lower at T3 compared to the other two stages. However, a multi-group SEM analysis, considering the time point as the moderation variable, showed that the strength of the structural relationships investigated within the model did not change over time. Discussion: Results confirm TPB validity in predicting Covid-19 vaccination intention at different stages of the vaccination campaign and shed light on the factors to be targeted to continue promoting vaccination.

Abstract
Background: Vaccination against Covid-19 is a crucial tool to combat the disease and control the pandemic. In Italy, despite the initial success of the vaccination campaign, vaccination rates are still not optimal in some population groups, as well as adherence to booster doses. To clarify whether and how vaccination acceptability has changed over time, this repeated cross-sectional study aimed to test the efficacy of an extended Theory of Planned Behaviour (TPB) model (including anticipated affects, risk perception, trust in science, trust in government, and religiosity) in predicting intention to get vaccinated in three different stages of the pandemic. Methods: Three self-report questionnaires were administered to three different convenience samples of Italian adults: at T1 (November 2020; N = 657), we evaluated intention to receive the future vaccine against Covid-19; at T2 (April 2021; N = 818), we measured actual vaccination intention; at T3 (February 2022; N = 605), we evaluated intention to continue vaccinating. Findings: Results from ANCOVAs indicated significant differences between the time points in all investigated variables, highlighting that vaccination acceptability was higher at T2 than T1, and lower at T3 compared to the other two stages. However, a multi-group SEM analysis, considering the time point as the moderation variable, showed that the strength of the structural relationships investigated within the model did not change over time. Discussion: Results confirm TPB validity in predicting Covid-19 vaccination intention at different stages of the vaccination campaign and shed light on the factors to be targeted to continue promoting vaccination.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
