Abstract

This study aimed to explore the main psychometric properties of the CDR, a new parent report instrument for the early screening of communication and language development of Greek-speaking children. Based on a representative sample of 1391 children aged 7 to 30 months (M= 19.45, SD= 6.91), results are presented on the sensitivity, internal
consistency, and convergent and divergent validity of its two major scales (‘Preverbal behaviors’ and ‘Verbal behaviors’) and their respective subscales (vocal and non-vocal preverbal communication, language comprehension, productive vocabulary, morphology and syntax). Results also illustrate the developmental patterns of the dimensions of communicative/linguistic development assessed, as well as the high and significant correlations among these dimensions of (pre)linguistic knowledge. Overall, results provide evidence on the functionality, validity and reliability of the CDR, and point to its use as a tool for the early screening of communication development in Greek-speaking children for clinical, educational and research purposes.
