Vaccine Hesitancy in the Autism Spectrum Disorder Context: Parental Vaccine Decision-Making and Coping with Stress Strategies

Despite no scientific evidence linking vaccines to Autism Spectrum Disorder (ASD), vaccine hesitancy persists among parents of children with ASD. This study aims to compare vaccine hesitancy and behaviors among parents of children with ASD, other Neurodevelopmental Disorders (NDD), and without NDD, and to examine the relationship between stress coping mechanisms and vaccine hesitancy, including comparing coping mechanisms between diagnostic groups as well as their association with hesitancy. In this cross-sectional study, one parent of each child with ASD, non-ASD NDD, or without NDD was included. Data were collected using a researcher-created form, the Vaccine Hesitancy Scale in Turkish, and the Coping Style Scale Brief Form. Vaccine hesitancy, parents’ COVID-19 vaccination status, and vaccination status of children’s younger siblings were analyzed through univariate and multivariate analyses, with a focus on correlations between vaccine hesitancy and coping styles. The study included one parent from each of 299 children. Parents of children with ASD showed an adjusted odds ratio of 2.66 (95
