Longitudinal impact of public stigma and courtesy stigma on parents of children with autism spectrum disorder: The moderating role of trait mindfulness

Background: Although the public and courtesy stigma of autism spectrum disorder (ASD) are prevalent, there are very few studies examining their adverse psychological effects on parents of children with ASD or exploring plausible factors that can alleviate these adverse effects. The present study addressed these literature gaps by investigating the longitudinal linkages of public and courtesy stigma to detrimental cognitive (i.e., self-stigma content and process) and affective (i.e., perceived stress and symptoms of depression and anxiety) consequences for parents of children with ASD and testing if these linkages would be moderated by trait mindfulness. Methods: At two time points separated by 12 months, 372 Hong Kong parents of children with ASD provided questionnaire data on public and courtesy stigma, mindfulness, self-stigma content and process, perceived stress, and symptoms of depression and anxiety. Results: Hierarchical regressions showed that public and courtesy stigma interacted significantly with mindfulness at baseline in predicting self-stigma content and process, perceived stress, and symptoms of depression and anxiety at follow-up. Moreover, simple slope analyses showed that the linkages of public and courtesy stigma to the five detrimental psychological consequences were weaker in parents with high mindfulness than in those with low mindfulness. Conclusions: Our findings highlight the longitudinal linkages of public and courtesy stigma to detrimental cognitive and affective consequences for parents of children with ASD, and reveal the plausible protective effects of mindfulness against such linkages. These findings suggest the po-tential utility of increasing mindfulness in parents of children with ASD in coping with com-munity stigma and improving mental health.
