How useful are the Adult Asperger Assessment and AQ-10 within an adult clinical population of all intellectual abilities?

How useful are the Adult Asperger Assessment and AQ-10 within an adult clinical population of all... Purpose– The Adult Asperger Assessment (AAA) was designed to be a screening tool to identify adults with Asperger syndrome and/or high-functioning autism. The AAA includes three questionnaires; the Autism Quotient (AQ), the Empathy Quotient (EQ) and the Relatives Questionnaire (RQ). The Autism Quotient-10 (AQ-10) was designed to be a “red flag” for healthcare professionals considering referral for ASD assessment. The purpose of this paper is to determine the usefulness of the AAA and AQ-10 as part of an adult autism diagnostic pathway that includes patients of all intellectual ability. Design/methodology/approach– Results were obtained for all patients who had received a clinical decision at Leeds Autism Diagnostic Service, which is a service that assesses patients of all intellectual ability, during 2015, n=214. Of these 132 were included in the analysis, 77 patients were excluded for not completing the AAA and four were excluded for not receiving a clinical decision. Findings– Results suggest that patients diagnosed with ASD without intellectual disabilities score on average 35 on the AQ, 17 on the EQ and 20 on the RQ. Those not diagnosed with ASD score on average 33 on the AQ, 22 on the EQ and 15 on the RQ. Patients with intellectual disabilities, scores are lower on the AQ, and higher on the EQ and RQ than those without intellectual disabilities. These results are the same regardless of diagnosis of ASD. The RQ is the only questionnaire to result in a significant difference between those diagnosed and not diagnosed. Results suggest that the AQ-10 is not useful in this clinical population. Research limitations/implications– This study was undertaken as part of a service development improvement process.

Abstract

Purpose– The Adult Asperger Assessment (AAA) was designed to be a screening tool to identify adults with Asperger syndrome and/or high-functioning autism. The AAA includes three questionnaires; the Autism Quotient (AQ), the Empathy Quotient (EQ) and the Relatives Questionnaire (RQ). The Autism Quotient-10 (AQ-10) was designed to be a “red flag” for healthcare professionals considering referral for ASD assessment. The purpose of this paper is to determine the usefulness of the AAA and AQ-10 as part of an adult autism diagnostic pathway that includes patients of all intellectual ability. Design/methodology/approach– Results were obtained for all patients who had received a clinical decision at Leeds Autism Diagnostic Service, which is a service that assesses patients of all intellectual ability, during 2015, n=214. Of these 132 were included in the analysis, 77 patients were excluded for not completing the AAA and four were excluded for not receiving a clinical decision. Findings– Results suggest that patients diagnosed with ASD without intellectual disabilities score on average 35 on the AQ, 17 on the EQ and 20 on the RQ. Those not diagnosed with ASD score on average 33 on the AQ, 22 on the EQ and 15 on the RQ. Patients with intellectual disabilities, scores are lower on the AQ, and higher on the EQ and RQ than those without intellectual disabilities. These results are the same regardless of diagnosis of ASD. The RQ is the only questionnaire to result in a significant difference between those diagnosed and not diagnosed. Results suggest that the AQ-10 is not useful in this clinical population. Research limitations/implications– This study was undertaken as part of a service development improvement process. The specific demographics of this clinical population may have influenced the findings. The process will need to be repeated to ensure that the results are consistent across time and increased sample size. The population of patients with an intellectual disability is small, further studies into the use of the AAA or the design of other intellectual disability specific screening tools should be pursued. It is of note that the AAA was never intended for use within an intellectual disability population. Originality/value– This is an original paper as it will be the first to consider the usefulness of each of the aspects of the AAA collectively. It will be the first to assess: the AQ-10 alongside the AAA, the usefulness of the AAA regardless of intellectual ability and the usefulness of the AAA within a clinical population by using the diagnostic outcome as the benchmark of the usefulness of the AAA scores. This paper will only be discussing the scores generated by the AAA, and the correlation of these scores with a diagnosis.
