Translation and cross-cultural adaptation into Brazilian Portuguese of the Children's Communication Checklist-2.

PURPOSE To translate the Children's Communication Checklist-2 (CCC-2) into Brazilian-Portuguese, to make its cross-cultural adaptation and to assess its internal reliability. METHODS The translation and cross-cultural adaptation followed the recommendations of the International Society for Pharmacoeconomics and Outcomes Research. The test was administered to 20 parents or caregivers of individuals with autism in order to investigate the level of understandability of the object under study. RESULTS After implementing the necessary adjustments, the final version of the Brazilian-Portuguese CCC-2 was achieved. Parents and/or caregivers did not make any suggestion for its adaptation. The final version was certified by the author of the original instrument and by the publisher responsible for marketing the CCC-2. Reliability of the instrument is acceptable, with values of internal consistency of its subscales ranging from 0.75 to 0.90. CONCLUSION The instrument can be used in the clinical evaluation of children with autism and developmental language disorder. However, further studies are needed to assess the reliability and validity of the instrument in Brazil.
