The adult experience of being diagnosed with autism spectrum disorder: A qualitative meta-synthesis.

There is a dearth of research into the experience of adult diagnosis of autism spectrum disorder, and targeted research is needed to understand the needs of these adults. The aim of this coproduced review was to assess existing qualitative data on the lived experience of receiving an autism spectrum disorder diagnosis, identify recurring themes, and synthesize them into a visual model representing the journey through diagnosis. Using thematic analysis, we analyzed qualitative data from 24 studies of adult experiences of autism spectrum disorder diagnosis from PsycINFO, Embase, MEDLINE, and CINAHL. Thirty-two "descriptive" themes and three superordinate themes were identified. These themes represented how factors relating to identity and relationships are impacted by the diagnosis of autism spectrum disorder and the role of adaptation and assimilation. While the diagnostic process was confusing and disappointing for many, it often led to a sense of relief and clarity regarding past experiences. It created opportunities to connect with other autistic individuals and to access services, though appropriate supports were widely lacking. Recommendations are made that the diagnosis process explicitly considers needs in relation to: the impact of the diagnosis on identity, interactions with other people, choices regarding disclosure, and whether and how to make informed adaptations. There is little research looking at the experience of individuals diagnosed with autism spectrum disorder as adults. Adults diagnosed with autism spectrum disorder face different challenges than children, and more research is needed to better understand those challenges. For this review, autistic and non-autistic researchers looked at research on the experience of receiving a diagnosis of autism spectrum disorder as an adult. We looked for themes in people's experience leading up to diagnosis, going through the diagnostic process, and living their life after diagnosis. We analyzed 24 studies and found three overarching themes that captured thirty-two themes describing the experience of diagnosis. The three overarching themes expressed issues with identity and relationships before and after the diagnosis and identified that the diagnosis of autism spectrum disorder in adulthood impacted people's adaptation to and assimilation (i.e. the making sense of and internalizing the diagnosis) of autism spectrum disorder. While the diagnostic process itself was confusing and disappointing for many, it often led to a sense of relief and clarity regarding past experiences and had effects on identity and self-esteem. It created opportunities to connect with other autistic individuals and to access services, though appropriate supports were widely lacking. Recommendations are made that the impact of the diagnosis on people's identity and choices about telling others about their diagnosis, and whether and how people want to make adaptations, should be discussed and thought through in the process of diagnosis.
