Abstract
Although autism is a childhood-onset neurodevelopmental disorder, its features change across the life course due to a combination of individual and contextual influences. However, the influence of contextual factors on development during childhood and beyond is less frequently studied than individual factors such as genetic variants that increase autism risk, IQ, language, and autistic features. Potentially important contexts include the family environment and socioeconomic status, social networks, school, work, services, neighborhood characteristics, environmental events, and sociocultural factors. Here, we articulate the benefit of studying contextual factors, and we offer selected examples of published longitudinal autism studies that have focused on how individuals develop within context. Expanding the autism research agenda to include the broader context in which autism emerges and changes across the life course can enhance understanding of how contexts influence the heterogeneity of autism, support strengths and resilience, or amplify disabilities. We describe challenges and opportunities for future research on contextual influences and provide a list of digital resources that can be integrated into autism data sets. It is important to conceptualize contextual influences on autism development as main exposures, not only as descriptive variables or factors needing statistical control.
