SAMPLE QUESTIONS

Example Questions From the Test

You will be asked to read a series of statements about personality characteristics and lifestyle. For each item, select one response that best describes how often the statement applies to you. Many of these questions concern your interactions with other people. Please base your answers primarily on how you behave with most people, rather than on specific relationships you may have with a spouse or other significant individuals (e.g., children, relatives, partners). People change over time, which can make it difficult to answer questions about personality characteristics. Please focus primarily on how you have been for most of your life, rather than during adolescence or during periods when you did not feel like your usual self. Even if you are unsure, please select the response option that seems most appropriate.

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.

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.
