CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this questionnaire measure?

It measures mild traits associated with the broader autism phenotype, such as social aloofness, pragmatic language differences, and rigidity. It is intended to capture subtle patterns that may not meet criteria for a clinical diagnosis.

Who is this questionnaire intended for?

It is used in research and clinical settings, including with relatives of individuals on the autism spectrum and with adults seeking clarification of subclinical traits. It is not designed for young children.

How long does it take and how many items are included?

Completion typically takes about 7 minutes. The questionnaire includes 36 items.

How should items be answered?

Select the response that best describes typical behavior over time rather than a single recent event. Answer all items and avoid leaving questions blank when possible.

How should results be interpreted?

Scores indicate the relative level of broad-phenotype traits across domains rather than a definitive diagnosis. Interpretation is most appropriate when considered alongside clinical history or research criteria.

WHAT THE TEST MEASURES

About This Assessment

Broad Autism Phenotype Questionnaire (BAPQ) Test - Symptoms and Signs

autism

This self-report measure is designed to screen for subtle autism-related traits in adults. The Broad Autism Phenotype Questionnaire (BAPQ) is commonly used in research and clinical contexts to characterize subclinical patterns associated with the broader autism phenotype.

The instrument includes 36 items and typically takes about 7 minutes to complete. Items assess everyday tendencies across domains such as social interaction style, pragmatic communication, and behavioral rigidity, yielding dimensional scores that can support case formulation or research phenotyping. Development is attributed here to psytests.org (2023).

Results from the Broad Autism Phenotype Questionnaire (BAPQ) are descriptive and should be interpreted in context (e.g., developmental history, current functioning, and collateral information). It is not intended to establish or rule out a diagnosis on its own and is best used as part of a broader assessment process.
