The usability of a Norwegian adaptation of the Children's Communication Checklist Second Edition (CCC-2) in differentiating between language impaired and non-language impaired 6- to 12-year-olds.

The aim of the present study was to evaluate if the Norwegian adaptation of the Children's Communication Checklist-2 (CCC-2) differentiates between a language impaired and a non-language impaired population and to make a first evaluation of the psychometric qualities of the questionnaire on a Norwegian sample. A total of 153 children aged 6-12 years participated in the study (45 language impaired and 108 non-language impaired). The Norwegian adaptation of the CCC-2 distinguished language impaired from non-language impaired children and thus seems to provide a useful screening tool for communication impairments in Norwegian children. The reliability of the CCC-2 appeared to be reasonable with internal consistency values ranging from 0.73 to 0.89.
