Abstract
Objective
To conduct a cross-cultural adaptation of the instrument: Autism Classification System of functioning: Social communication (ACSF: SC), which allows clinicians to classify the level of the social communication function of children with autism spectrum disorder (ASD), for its use in Brazil.
Method
Methodological study of cross-cultural adaptation of the instrument ACSF: SC. We followed recommendations for transcultural adaptation of health protocols, which included assured permission, translation, reverse translation, review, and panel of experts.
Results
The evaluation of the experts revealed that the translated version of the ACSF: SC instrument was well understood conceptually and culturally adequate, with 48 sentences presenting a concordance index greater than 90% regarding conceptual and cultural equivalence. Phrases that did not achieve adequate levels of agreement were reviewed, according to experts’ suggestions.
Conclusion
Equivalence between the original ACSF: SC and its translated into Brazilian Portuguese is guaranteed, as it reached a concordance index above 90%. The Brazilian version of the ACSF: SC will be suitable for clinical use once its psychometrics properties are established.
