How to measure camouflaging? A conceptual replication of the validation of the Camouflaging Autistic Traits Questionnaire in Dutch adults

•The CAT-Q-NL, given its face validity, can be helpful for the clinician’s toolbox.•There are challenges in measuring camouflaging using the CAT-Q-NL.•In autistic adults, camouflaging can be measured in a similar manner to the CAT-Q.•We cannot compare scores on the CAT-Q-NL between autistic and non-autistic adults.•Scores do not represent the same in both groups due to a lack of measurement invariance.
