| Summary: | 碩士 === 臺北市立教育大學 === 溝通障礙碩士學位學程 === 96 === The main purpose of this study was to examine the concurrent validity and predictive validity of the “Birth to Three Infant-Toddlers Communication and Language Developmental Screening Test,（0-3CLST）” as well as to investigate the best cutoff points using to screen the high risk children.
There are 153 subjects (age of 17-36 months) participating in testing concurrent validity and 225 subjects (NH=206, DD=19) in predictive validity. Comparisons were made between the 0-3CLST and language subtest from “the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT) screening test”. Correlation analyses, classification analyses, and ROC analyses were also conducted.
The study has found that (1) the concurrent validity was .77(p<.01). (2)0-3CLST has good predictive validity for the language subtest of CDIIT screening test .78(p<.01). (3)The AUC.81~ .85 means that the test possesses good classification accuracy. (4) When the cutoff point is set at -1.5SD, the following numbers show good prediction: the SEN of .70, SPE of .99, Hit Rate .96 and PPV of .88.
The evidence, therefore, has given strong support to suggest that the 0-3CLST has good concurrent validity and predictive validity, which can be used effectively in screening children with communication and language developmental delays.
