Understanding profound autism: implications for stigma and supports.

Area of Science:

• Neurodevelopmental Disorders
• Autism Spectrum Disorder Research
• Public Health

Background:

• Societal stigma and misunderstanding of autism spectrum disorder (ASD) negatively impact autistic individuals and families.
• Profound autism, a severe form of ASD, affects a marginalized group with significant service needs.
• Limited data exists on the prevalence and lived experiences of individuals with profound autism.

Purpose of the Study:

• To determine the prevalence of profound autism in diverse populations.
• To explore the experiences of caregivers of profoundly autistic adults.
• To identify key challenges faced by families supporting individuals with profound autism.

Main Methods:

• A mixed-methods approach was employed, combining prevalence estimation and qualitative analysis.
• Prevalence of profound autism was assessed across six distinct samples in the United States and Western Europe.
• Inductive thematic analysis was used to code interviews with 20 caregivers of profoundly autistic adults.

Main Results:

• Prevalence of profound autism ranged from 11% to 48% across the studied samples, with variations by gender, race, and ethnicity.
• Two major themes emerged: community perceptions of autism and family support/advocacy challenges.
• A significant majority of caregivers (85%) reported experiencing perceived stigma, even when not directly probed.

Conclusions:

• Future research is crucial to understand the specific needs and stigma experienced by individuals with profound autism and their families.
• Addressing the unique challenges and support requirements of this population is essential for improving their quality of life.
• Continued investigation across the lifespan is needed to inform effective interventions and reduce societal stigma.
