Validation of the Observer-Reported Communication Ability (ORCA) measure for individuals with Rett syndrome

CONCLUSIONS: This study provided initial support that the modified ORCA measure is an acceptable caregiver-reported measure of communication ability for females with RTT. Future work should include evaluation of longitudinal validity of the measure and its associations with clinician- and performance-based measures in diverse samples.PMID:37536121 | DOI:10.1016/j.ejpn.2023.07.007
