There is minimal research regarding the personal experiences and perceptions of youth with autism spectrum disorder (ASD). Yet, the positive and negative perceptions that youth internalize about their diagnoses are crucial, as they may have a strong impact on individuals' self-concept and well-being. This paper utilizes mixed methods to describe the perceptions of 38 adolescents with ASD about their diagnoses, as elicited via semi-structured interviews. Quantitative analyses explore links between youths' perceptions and other aspects of their social--emotional well-being. Implications are highlighted regarding the importance of shifting the narrative that individuals with ASD develop about themselves and their diagnoses.
