This study investigated the role of acceptance during the transition process among autistic young adults, parents, and practitioners. Six focus groups were run and thematic analysis was used to identify four themes: Youth on the autism spectrum discussed transition as a time where "Self-Advocacy and Self-Acceptance" were salient. Both youth and parents discussed the "Lack of Understanding and Acceptance" they experience. Particularly, youth highlighted the lack of understanding of sensory needs and parents underscored the lack of understanding by medical professionals. In contrast, practitioners highlighted the presence of "Community Openness." Both practitioners and parents discussed "Finding Personal Support through Acceptance." Self-acceptance and acceptance of autism are imperative for autistic young adults and families to achieve well-being.
