The 70-item questionnaire is completed by a respondent who has regular contact (3-4 days per week) with the individual and knows them well (partner, parent, friend or carer).
50 behavioural statements focus on communicative weaknesses and 20 on communicative strengths.
The CC-A is suitable for use with adults who have a developmental disorder such as Specific Language Impairment, an autism spectrum disorder, Downs Syndrome, Fragile X syndrome, learning difficulties, and for adults with an acquired disorder, such as head injury.
It also helps to identify subtle communicative difficulties indicative of the broader autism phenotype in individuals who are related to people with heritable disorders such as an ASD.
Z scores, scaled scores and percentiles are provided for the following 3 composites: Language Structure, Pragmatic Skills, Social Engagement, in addition to a total z score.
