The RAADS-14 Screen, explained

The RAADS-14 Screen exists because the full RAADS-R is long. Psychiatric outpatient clinics see many adults whose autism was never identified, often hidden behind anxiety, mood or attention problems. The Swedish team behind the RAADS-14 wanted a quick first filter that clinicians could hand out routinely, to spot who might need a full assessment.

How it was developed

The researchers gave a shortened RAADS-R to adults with autism and to adults with other psychiatric diagnoses, then picked the statements that best separated the groups. Two senior psychiatrists and a senior psychologist checked that the final 14 matched autism features in the then-proposed DSM-5. The study included 135 autistic adults, 508 adults with conditions such as ADHD, anxiety, mood and psychotic disorders, and a large non-psychiatric comparison group.

The three areas it covers

Factor analysis grouped the statements into three areas. Seven relate to mentalizing, meaning reading other people's intentions and meanings. Four relate to social anxiety. Three relate to sensory reactivity. Clinicians can look at these areas separately, but the total is what the cut-off applies to.

RAADS-14 scoring and interpretation

Put plainly, the cut-off was chosen to miss very few autistic people, at the cost of flagging many others. That is a deliberate choice for a screener in a psychiatric clinic, where a missed diagnosis can mean years of treatment that does not fit. It also means a score of 14 or more, on its own, says little about any one person. In a group with high rates of ADHD, more than half of those above the line may not be autistic.

Gender differences

The original paper reported scores separately for men and women. A later Irish study of young adults with ADHD found that autistic women scored higher than autistic men on all three RAADS-14 areas, and that sensory sensitivity was higher in women whether or not they were autistic. That matters because women are more often missed, and a screener that leans on social statements alone could miss them too. Samples, ages and settings differ between studies, so no single result settles the question.

Who may use it, and where the official version is

The RAADS-14 Screen items and scoring appear in the open-access 2013 article in Molecular Autism, in a table and a downloadable supplementary file. The article is under an open license, but the statements themselves come from the RAADS-R, which its authors released for noncommercial use only. That is why SpectrumFox describes the RAADS-14 rather than hosting it. Clinicians and researchers should read the original article for the official wording.

What the cut-off means in everyday terms

Imagine a busy outpatient clinic where many patients have ADHD, anxiety or mood problems and a few are autistic without knowing it. Handing everyone the RAADS-14 would catch nearly all of the autistic patients. It would also put a large share of the others above 14. The clinic would then need to follow up with more careful assessment, which is exactly how the authors intended it to work. The screen narrows the field. It never makes the final call.

RAADS-14 versus RAADS-R

The RAADS-14 is a quick filter for clinics. The RAADS-R is longer, covers more areas including language and circumscribed interests, and was designed to support a clinician during assessment. Neither diagnoses autism. If you scored high on either, the useful next step is the same: a conversation with a professional who can look at your history and current life together.
