Thesis (B.Sc)--University of Hong Kong, 2010."A dissertation submitted in partial fulfillment of the requirements for the Bachelor of Science (Speech and Hearing Sciences), The University of Hong Kong, 30 June, 2010."Includes bibliographical references (p. 26-30).The first aim of this study is to investigate the criterion validity of the Chinese
Communicative Development Inventories (CCDI) using direct measures of the
children’s language. The direct measures were the Expressive score of the Reynell
Developmental Language Scales (E-RDLS) and mean length of utterance (MLU).
Twenty-seven parents and their children aged between 25 and 30 months old
participated. The children’s CCDI scores were moderately correlated with their
E-RDLS scores and MLUs, indicating that CCDI demonstrated adequate criterion
validity. The second aim of the study is to examine CCDI’s screening accuracy in 11
children with normal language and 3 children with language delay. These children’s
language status was defined by their performance in E-RDLS and MLU. CCDI’s
sensitivity and specificity was 33% and 91% respectively, suggesting that CCDI
could accurately screen children with normal language but not language delay in this
small sample. Clinical implications of these findings are discussed.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science
