Autism Spectrum Quotient, Brief (AQ-10)

The AQ-10 (Autism Spectrum Quotient, Brief) is a 10-item self-report questionnaire that screens adults for autistic traits, developed as a shortened version of the full 50-item Autism Spectrum Quotient (AQ). Its purpose is rapid identification of individuals who may benefit from a full autism assessment.

Each item reflects a high-discriminating question drawn from the original AQ domains: Social Skills, Communication, Attention Switching, Attention to Detail, and Imagination. Scores range from 0–10, with 6 or more recommended by NICE as the threshold for referral for a comprehensive autism assessment. The AQ-10 is not a diagnostic tool but serves as an efficient “red flag” screener suitable for busy clinical environments.

  • At intake when autism is part of the presenting concern
  • Once, unless a reassessment is clinically relevant
  • Repeat only if self-awareness, symptoms, or masking patterns have meaningfully changed
  • Not intended for routine monitoring

  • 10 self-report items, scored 0–1 each. Total score 0–10; higher scores reflect more autistic traits. Validated cut-point ≥6 for referral consideration in adults.

    Total scoreInterpretation
    6+Positive screenScore meets the ≥6 threshold associated with referral for a comprehensive autism assessment. A positive screen does not confirm an autism spectrum condition.
    0–5Below thresholdScore is below the ≥6 referral threshold. A low score does not rule out autism spectrum condition, particularly in individuals who mask or camouflage autistic traits.

The AQ-10 (Autism Spectrum Quotient, Brief) is a 10-item self-report questionnaire that screens adults for autistic traits and helps decide whether a full autism assessment is warranted. Totals run 0 to 10, and 6 or above is the referral cutoff [1].

How was the AQ-10 developed?

The AQ-10 was built by item reduction from the full 50-item Autism Spectrum Quotient [2]. Its developers took the 10 items with the best test accuracy, using more than 1,000 people with an autism diagnosis and 3,000 controls who had completed the full-length measure [1].

The full AQ was designed for adults of average or above-average intelligence [2], and the AQ-10 was intended as a "red flag" tool for frontline professionals deciding whether to refer for a full diagnostic assessment [1].

What does the AQ-10 measure?

The AQ-10 measures core autistic traits, capturing difficulties or differences in:

  • Social intuition and comfort
  • Flexibility and attention switching
  • Literal or detail-oriented thinking
  • Communication and conversational nuance
  • Imagination and perspective-taking

These items reflect the same cognitive–behavioural constructs as the 50-item AQ but in highly condensed form.

How do you give the AQ-10?

The AQ-10 is a self-report questionnaire. Individuals complete it themselves, typically in a few minutes; it does not require clinician administration.

  • Ideal for primary care, community mental health, and diagnostic triage
  • Best used early in assessment workflows
  • Responses may be influenced by masking/camouflaging, anxiety, or social learning
  • Not validated for individuals with intellectual disability or limited literacy
  • Works well in combination with the full AQ, the RAADS-R, or developmental history tools

How do you score and interpret the AQ-10?

The AQ-10 produces a single total score from 0 to 10.

Standard interpretation (aligned with NICE):

  • 0–5: Below screening threshold
  • ≥6: Positive screen; consider referral for comprehensive autism assessment

Interpretation Notes:

  • A positive screen does not indicate autism; it signals that further evaluation may be appropriate
  • A score below 6 does not rule out autism, especially in individuals who mask or compensate socially
  • Cultural, linguistic, gendered, and neurodivergent presentation differences influence responses
  • Should be reviewed alongside developmental history, functioning, sensory profile, and clinical interview data

Psychometric properties

Reliability

  • Internal consistency was above 0.85 in the development study [1]
  • Items were selected for their discrimination between more than 1,000 autistic people and 3,000 controls [1]

Validity

  • Development study. At a cutoff of 6, the adult version had sensitivity of 0.88, specificity of 0.91 and positive predictive value of 0.85 [1]
  • Referred outpatients. In 210 adults referred for autism assessment and 63 controls, the AQ short forms (AQ-28 and AQ-10) had specificity of 70% and 72%, and sensitivity and specificity were much lower than in earlier reports [3]
  • Designed to support referral decisions, not diagnosis

Limitations

  • Not diagnostic; cannot determine autism on its own
  • Does not capture sensory experiences, camouflaging, burnout, or female-presenting autism profiles
  • Binary scoring may oversimplify nuanced traits
  • Very brief, can miss subtle presentations
  • In a referred outpatient sample, the AQ-10 did not predict a diagnosis reliably enough to stand on its own [3]

FAQ

  • How is the AQ-10 scored?

    Each of the 10 items is scored 0 or 1 based on the direction of the response. Scores consistent with autistic traits receive 1 point; all other responses score 0. The total score ranges from 0 to 10, with higher scores indicating a greater number of autistic traits endorsed.

  • What score on the AQ-10 suggests a referral for further assessment?

    A score of 6 or above is the recommended threshold, established in the 2012 development study. At this cut-point the adult version showed sensitivity of 0.88 and specificity of 0.91. A positive screen indicates that a comprehensive autism assessment may be appropriate, not that autism is present.

  • Is the AQ-10 a self-report tool or clinician-administered?

    The AQ-10 is a self-report questionnaire. Individuals complete it themselves, typically in a few minutes. It does not require clinician administration, making it well suited to initial triage in primary care, mental health intake, or referral pathways.

  • Can the AQ-10 diagnose autism spectrum condition?

    No. The AQ-10 is a screening tool only and cannot provide a diagnosis. A positive screen identifies individuals who may benefit from a full multidisciplinary autism assessment; it does not confirm or rule out an autism spectrum condition on its own.
