Objective: To evaluate concurrent validity between the Korean-Ages and Stages Questionnaires (K-ASQ) and the Denver Developmental Screening Test II (DDST II), and to evaluate the validity of the K-ASQ as a screening tool for detecting developmental delay of Korean children.
Method: A retrospective chart review was done to examine concurrent validity of the screening potentials for developmental delay between the K-ASQ and the DDST II (n=226). We examined validity of the K-ASQ compared with Capute scale (n=141) and Alberta Infant Motor Scale (AIMS) (n=69) as a gold standard of developmental delay. Correlation analysis was used to determine the strength of the associations between tests.
Results: A fair to good strength relationship (k=0.442, p<0.05) was found between the K-ASQ and the DDST II. Th e test characteristics of the K-ASQ were sensitivity 76.3-90.2%, specifi city 62.5-76.5%, positive likelihood ratio (PLR) 2.41-3.40, and negative likelihood ratio (NLR) 0.16-0.32.
Conclusion: Evidence of concurrent validity of the K-ASQ with DDST II was found. K-ASQ can be used for screening of developmental delay.
