A nationwide survey on quality of life and associated factors of adults with high-functioning autism spectrum disorders.
Early diagnosis and steady maternal support protect adult quality of life in HFASD, while current aggression quickly erodes it.
01Research in Context
What this study did
Kamio et al. (2013) mailed a quality-of-life survey to adults with high-functioning autism across Japan. They asked about mood, work, friends, and daily hassles. They also asked about early life: who first noticed autism, when, and what help the family gave.
The team then looked for patterns. Did early diagnosis link to better adult life? Did family support matter? Did current behavior problems change the picture?
What they found
Adults with HFASD scored lower on every psychosocial area than typical Japanese adults. The gap was large and consistent.
Two childhood facts predicted better adult life: learning the diagnosis early and having a supportive mother. One adult fact predicted worse life: showing aggressive behavior now. Surprisingly, preschool language level had no link to adult quality of life.
How this fits with other research
Low et al. (2024) extends the story. They found Malaysian university students who self-report autism traits also feel lower quality of life. Together the papers show the problem is not just in clinic-diagnosed Japanese adults; it spans cultures and diagnostic borders.
Khanna et al. (2011) flips the lens. They asked U.S. caregivers of children with autism about their own quality of life. Caregivers also scored very low, and child behavior problems were the biggest drain. The same risk factor—aggressive behavior—hurts both the adult with autism and the parent raising a child with autism.
Garrido et al. (2021) adds a twist. In Spanish families, parents who easily understand numbers and risk information report higher family quality of life. So adult outcomes may hinge on both early support and current cognitive skills.
Why it matters
You cannot change a client’s preschool language history, but you can act on the two levers this study flags. First, share diagnosis early and clearly; second, teach caregivers how to stay warm and consistent. When you see aggressive behavior in teens or adults, treat it fast—every episode drags down future life satisfaction. Track caregiver numeracy too; if they struggle with data, add visual supports. These small moves may protect quality of life for both your client and their family.

03Original abstract
The psychosocial outcomes of individuals with high-functioning autism spectrum disorder (HFASD) appear to be diverse and are often poor relative to their intellectual or language level. To identify predictive variables that are potentially ameliorable by therapeutic intervention, this study investigated self-reported psychosocial quality of life and associated factors for adults with HFASD. All participants (n = 154) had a diagnosis of autism spectrum disorder, were over 18 years of age, lived in the community, and had used one or more support services during the survey period. The results demonstrated that psychosocial quality of life was lower than that of the general Japanese adult population. Environmental factors, such as mother's support and early diagnosis, were associated with better quality of life, and aggressive behaviors were associated with poorer quality of life, while expressive language level at preschool years, a conventional outcome predictor, did not predict quality of life. These results emphasize that quality of life measures should be included as outcome indicators in treating individuals with HFASD.
