Abstract
Background: Camouflaging of autistic traits involves hiding or compensating for autistic characteristics, often due to stigma or a desire to fit in with others. This behaviour has been associated with mental health issues in autistic individuals. The 2 5-item Camouflaging Autistic Traits Questionnaire (CAT-Q) is the most commonly used self-report measure of camouflaging. In this study, a 9-item short form version was developed for use in clinical and research settings. Aims: To construct and psychometrically validate a brief self-report measure of camouflaging. Method: The Camouflaging Autistic Traits Questionnaire – Short Form (CATQ-SF) was developed and its factor structure and psychometric properties were evaluated in two studies. Study 1 used a large, online sample of autistic and non-autistic adults (N = 832) to evaluate the factor structure, psychometric properties, and measurement invariance of the CATQ-SF. Study 2 used an independent sample of autistic and non-autistic adults (N = 80) to test Study 1's findings. Results: In Study 1, evidence for a three-factor structure was observed, with good internal consistency (combined autistic & non-autistic α = 0.84). In addition, the instrument demonstrated measurement invariance, and reliably predicted higher levels of autistic traits. In Study 2, the 3-factor structure was replicated, and good internal consistency was again observed (combined autistic and non-autistic α = 0.89). In both studies, psychometric properties were of similar or higher validity compared to the full-form CAT-Q. Conclusions: The CATQ-SF can be used by clinicians and researchers to measure camouflaging in autistic and non-autistic adults quickly and reliably.
