Autism at 30: Conceptualizations for adult research and clinical practice.

Researchers followed 115 people with autism for 30 years from early childhood into adulthood. The study included a diverse group with different abilities, backgrounds, and living situations. They found that while autistic adults face unique challenges, they also share many similarities with other adults, especially when it comes to quality of life. As more autistic children grow up, we need better research and services for autistic adults.

This narrative review follows 115 individuals diagnosed with autism between ages 2-3 for three decades to examine adult outcomes. The diverse sample includes 20% Black/mixed race participants, 13% females, 43% from rural areas, and 37% with non-college educated caregivers. Fifty participants have average cognitive abilities and verbal fluency, while 65 have intellectual disabilities and/or are minimally verbal. The review highlights that while autistic adults' experiences differ from the general population in some ways, important similarities exist, particularly regarding quality of life.

As the autistic adult population grows and increasingly seeks services, the authors emphasize the need for high-quality research and clinical services tailored to this population.

Findings emphasize the need for lifespan approaches to autism support and highlight the growing population of autistic adults requiring clinical services. The diversity of outcomes suggests individualized approaches are essential. Quality of life similarities with general population indicate potential for positive adult outcomes with appropriate support.

This is a narrative review of a single longitudinal cohort study rather than a systematic review or meta-analysis. The abstract does not specify methodology for data collection or analysis. Limited information is provided about specific outcome measures or comparative data with neurotypical populations.

Autism spectrum disorder is one of the most common neurodevelopmental conditions diagnosed in children. Most autism research, intervention, and policy focus exclusively on this condition in childhood, but autism often persists across the life course. This narrative review leverages data from 115 participants first diagnosed with autism between ages 2 and 3 years and subsequently followed for 3 decades (= 30.93 years,= 3.41) to highlight key aspects of adult life and experiences for autistic individuals identified in early childhood. Compared to other autism samples, the participants described here are relatively diverse: 20% are Black or mixed race; 13% are female; 43% reside in Census-designated rural locations; and 37% have a primary caregiver without a college degree.

Fifty participants have average cognitive abilities (mean intellectual quotient [] = 98.8,= 19.3) and are verbally fluent; the remaining 65 have an intellectual disability (= 28.5,= 17.7) and/or are minimally verbal. In some ways, the adult experiences of autistic individuals are quite distinct from those of the general population, but important similarities exist also, particularly related to quality of life. As the number of autistic adults continues to rise, and increasing numbers of autistic adults seek out clinical and community services, high-quality research and clinical services focused on this population should be a priority for psychological science and practice.
