A comparison of methods for measuring camouflaging in autism.

Interest in social camouflaging has led to a multiplicity of measurement methods of uncertain validity. This two-part investigation first used a systematic review ("Study 1") to identify and appraise methods used to quantify camouflaging of autistic traits, using the Consensus-based Standards for the Selection of Health Status Measurement Instruments checklist. A total of 16 distinct measurement tools were identified; all are in the preliminary phases of psychometric evaluation. The systematic review highlighted: (1) the need for parent-report tools which specifically measure camouflaging; and (2) a lack of studies looking at associations between different methods of camouflaging, which limits understanding of their validity. "Study 2" aimed to begin to address these gaps in knowledge. We created a parent-report version of the Camouflaging Autistic Traits Questionnaire (CAT-Q) and evaluated its concurrent validity in autistic young people by examining associations with the self-report CAT-Q and a discrepancy measure. Discriminant validity was investigated by comparing all three methods of measuring camouflaging to a measure of social skills, to test whether they assess a construct distinct from social ability. The self- and parent-report CAT-Q were significantly related (r = 0.47, 95% CI = 0.24-0.65), and were related weakly (r = 0.20, 95% CI = -0.06 to 0.43) and strongly (r = 0.46, 95% CI = 0.23-0.64), respectively, to the discrepancy approach. No measure was associated with social skills. Improving the psychometric properties of these methods, and introducing a novel parent-report measure, may help selection of appropriate methods in future research and integration into clinical practice.
