Psychometric properties of the awareness questionnaire, patient competency rating scale and Dysexecutive Questionnaire in patients with acquired brain injury.

Overall, the total scale scores of patient forms of all questionnaires demonstrated sufficient psychometric properties. Psychometric properties of subscales are questionable. We could not replicate the factor structures of AQ, PCRS and DEX: the items within subscales differed with previous findings. Additional research into the test-retest, inter-rater reliability and responsiveness of relative and clinician forms is required.
