ABSTRACT
Objectives
The Communication and Symbolic Behavior Scale Developmental Profile (CSBS DP) consists of three subtests: Infant Toddler Checklist (ITC), Behavior Sample (BS), and Caregiver Questionnaire (CQ). While the reliability and validity of the Korean edition of the CSBS DP BS had been previously reported, the reliability and validity of other two tests have not reported yet. This study aimed to examine that the reliability and validity of the Korean edition of the CSBS DP CQ.
Methods
The CSBS DP CQ was trans¬lated into Korean and then reviewed by 3 child language professionals for the accuracy of the translation. 794 caregivers who have typically developing toddlers age ranged from 6-24 months completed the K-CSBS DP CQ and 679 data had been analyzed among them. The reliability by internal consistency, the concurrent validity by correlation between K-CSBS DP BS and SELSI each, the construct validity by confirmation factor analysis, and the developmental validity by ANOVA according to age group measured.
Results
The reliability of the K-CSBS DP CQ measured by internal consistency was high and the correlation measured with the K-CSBS DP BS and SELSI were each significant as well. The results of confirmatory factor analysis confirmed the three factors (social, speech, and symbolic) of the original CSBS DP CQ and the developmental validity was confirmed by results of ANOVA.
Conclusion
Through this study, the K-CSBS DP CQ has been confirmed as a valid and reliable for assessing early communication of Korean toddlers. It can be used for assessing early communication abilities of typically developing toddlers and children with developmental disabilities as well.
