Comprehensive comparison of self-administered questionnaires for measuring quantitative autistic traits in adults.

Nishiyama et al. (2014) lined up every short self-report form that claims to measure autism traits in adults.

They tested how steady, how consistent, and how well each form tells autistic and non-autistic adults apart.

The forms were the Autism-Spectrum Quotient (AQ), the SRS-2 Adult Self-report (SRS2-AS), and the newer Subthreshold Autism Trait Questionnaire (SATQ).

All forms stayed steady when people took them twice, but only the SATQ stayed both short and solid.

The AQ and SRS2-AS showed weak internal consistency and mixed ability to separate groups.

Bottom line: SATQ gives you the cleanest quick picture of adult traits.

Griffith et al. (2012) built the SATQ two years earlier and already showed it worked in young adults.

Nishiyama et al. (2014) now widen the age range and still crown the SATQ best, so the newer work extends the first study.

Gergoudis et al. (2020) trimmed the SRS-2 for a rare genetic syndrome and also found shorter can be stronger, echoing the SATQ win.

No clash here—just more proof that brief, focused items beat long, noisy ones.

If you screen college students, job applicants, or clinic referrals, you now have data to pick the 24-item SATQ over longer tools. You save time, cut respondent fatigue, and keep decent psychometric footing. Swap it into your intake packet next week.
