This is an individual National Research Service Award for pre-doctoral research training, which provides support for promising doctoral candidates who will be performing dissertation research and training in a scientific health-related field. Asperger's syndrome (AS) is an autism spectrum disorder characterized by impairment in social interaction and restricted, repetitive interests. But is this "social disorder" best thought of as a disease of the individual brain, or as a state of ongoing interpersonal mismatch with others? The experiences of this growing population in "real life" educational and community settings requires further study from a lifespan perspective. As this cohort of individuals moves into adolescence and adulthood, it becomes increasingly important to understand their understanding of the diagnosis in order to design methods of service provision that will continue to be relevant and effective. In this study, the fellow will use a mixed-method, comparative study of clinical and educational programs for adolescents with AS. In particular, the project responds to concerns raised by an increasingly vocal group of adult autistic self-advocates, claiming that defining autism as brain-based biomedical pathology rather than an inherent aspect of identity represents a stigmatizing and demoralizing misconception about the nature of these disorders.
