The Broad Autism Phenotype Questionnaire (original) (raw)

Abstract

The broad autism phenotype (BAP) is a set of personality and language characteristics that reflect the phenotypic expression of the genetic liability to autism, in non-autistic relatives of autistic individuals. These characteristics are milder but qualitatively similar to the defining features of autism. A new instrument designed to measure the BAP in adults, the Broad Autism Phenotype Questionnaire (BAPQ), was administered to 86 parents of autistic individuals and 64 community control parents. Sensitivity and specificity of the BAPQ for detecting the BAP were high (>70%). Parents of children with autism had significantly higher scores on all three subscales: aloof personality, rigid personality, and pragmatic language. This instrument provides a valid and efficient measure for characterizing the BAP.

Instructions

You are about to fill out a series of statements related to personality and lifestyle. For each question, circle that answer that best describes how often that statement applies to you. Many of these questions ask about your interactions with other people. Please think about the way you are with most people, rather than special relationships you may have with spouses or significant others, children, siblings, and parents. Everyone changes over time, which can make it hard to fill out questions about personality. Think about the way you have been the majority of your adult life, rather than the way you were as a teenager, or times you may have felt different than normal. You must answer each question, and give only one answer per question. If you are confused, please give it your best guess.
