Validity of developmental delay screening test; using latent class model

Abstract

The purpose of this study was measured and compared validity including sensitivity, specificity and positive predictive values using latent class analysis. Data were collected from 229 children from 3 to 5 years old in local nurseries whose parents agreed with the purpose of study. Especially this study, validity of each test was measured for three developmental screening tests after establishing the last one developmental screening test as a standard and utility of the four screening tests was calculated four two latent class model. When a child was included in the developmental delay class through a latent class analysis. Positive predictive values were 86%-54% in K-DIAL3, K-DDSTII, K-ASQ and K-CDI respectively and those of combination of two of them were 95%-78%. It was suggested that tests of children of two or more rather than one and shall be used to of developmental screening tests for detecting developmental delay. © 2011 Springer-Verlag.
