[Adaptation and validation of the MoVac-flu scale on motivation towards the flu vaccine].

Objective: To translate, adapt and validate the psychometric properties of MoVac-flu scale in order to be used in Spanish.
Method: The present research was an analytical observational study of cross-cultural adaptation and validation into Spanish of the MoVac-flu scale. It has been carried out between the months of March and July 2022. The sample size was 142 people who were obtained by consecutive sampling. The processes used for the adaptation have been translation, validation by a committee of experts, back-translation and pilot test. For validation, the psychometric properties of reliability, internal consistency, appearance validity, content validity, utility and ceiling-floor effect have been verified.
Results: The internal consistency of the MoVac-flu scale in its version translated into Spanish was high, showing a McDonald's ω of 0.914.
Conclusions: The MoVac-flu scale in Spanish allows to measure the degree of motivation towards vaccination against influenza in the adult population.
