Systematic Review of the Relationship Between Autism Stigma and Informal Caregiver Mental Health.

All quantitative studies used non-random sampling, so the results may not apply to all caregiver populations. The review included only English and Dutch language papers, which may have missed relevant research. Most studies focused on parents of young children, so findings may not apply to caregivers of adults or other relative types like grandparents. The lead researcher is a father of an autistic child, which may have influenced the interpretation of the findings despite efforts to mitigate bias. No studies examined the impact of comorbidities like fragile X syndrome or epilepsy on the relationship between stigma and mental health.

Do not interpret the consistent association between stigma and poor mental health as proof that reducing stigma will automatically improve caregiver wellbeing. The included studies were cross-sectional or qualitative, so they show a link but do not prove that changing stigma causes a change in mental health.
