title: [The Spanish adapted version of the Children's Communication Checklist identifies disorders of pragmatic use of language and differentiates between clinical subtypes].
abstract: BACKGROUND
  The Children's Communication Checklist (CCC) by Bishop is a useful scale for evaluation of pragmatic verbal abilities in school children. The aim of the study is to ascertain the validity and reliability of the CCC in Spanish.
  
  
  METHODS
  Answers to the CCC items by parents of 360 children with normal intelligence were analyzed. There were five groups: 160 control children; 68 children with attention deficit hyperactivity disorder, 77 with procedural non-verbal disorder, 25 children with social communication disorder and 30 with autism spectrum disorder. Investigations included: factorial analysis in order to cluster checklist items, reliability analyses of the proposed scales and discriminant analysis to check whether the scale correctly classifies children with pragmatic verbal abilities.
  
  
  RESULTS
  Seven factors were obtained (Kaiser-Meyer-Olkin: 0.852) with moderate similarity with those of the original scale: social relationships, interests, and five more that can be grouped into pragmatic verbal ability (conversational abilities, coherence-comprehension, empathy nonverbal communication and appropriateness). All factors are significantly correlated with each other in the control group, and the five that compose pragmatic verbal ability correlate with each other in the clinical groups (Pearson r). The scales have good reliability (Cronbach's alpha: 0.914). The questionnaire correctly classifies 98.9% of grouped cases with and without pragmatic disorder and 78% of subjects in their appropriate clinical group. Besides, the questionnaire allows to differentiate the pathologies according to the presence and intensity of the symptoms.
  
  
  CONCLUSIONS
  This Spanish version of the CCC is highly valid and reliable. The proposed statistics can be used as normative-reference values.
