Development of a patient-centered conceptual model of the impact of living with autism spectrum disorder.

The aim of this study was to generate a patient-centered conceptual model of the impact of living with autism spectrum disorder, which can be used to support the selection of outcome measures for clinical trials. Following an initial literature review to identify preliminary concepts and inform an interview guide, in-depth face-to-face interviews were conducted with adolescents and adults with autism spectrum disorder (IQ ⩾ 70) (n = 10), as well as parents of children, adolescents, and adults with autism spectrum disorder (IQ ⩾ 70) (n = 26). Data were analyzed using established qualitative research methods. The resultant conceptual model contains three interrelated domains reflecting core symptoms of autism spectrum disorder (communication deficits, socialization deficits, and restrictive, repetitive patterns of behavior), three domains reflecting associated symptoms of autism spectrum disorder (physical, cognitive, and emotional/behavioral), and three domains representing the impacts of living with autism spectrum disorder (impacts on activities of daily living, school/work, and social life). Interview respondents also cited social communication deficits as priority targets for new treatments. The conceptual model provides a patient-centered perspective of relevant concepts of autism spectrum disorder from the perspectives of people with autism spectrum disorder and their parents and offers a valuable tool for identifying valid patient-centered outcome measures for future clinical trials.
