The design and evaluation of the scale went through three phases: item development, scale development, and evaluation.
Results: The sampling adequacy of Kaiser-Meyer-Olkin measure was 0.8 at significance level of Bartlett's test of sphericity Conclusion: The designed scale to assess hesitancy towards new vaccines based on health belief model was valid among the studied population; also, it was a reliable scale according to Cronbach's alpha.
