Concurrent validity of the scale for screening of developmental delay.
This study establishes the concurrent validity of the Screening Scale of Developmental Delay II (SSDD-II) with the Bayley Scale of Infant Development II (BSID-II). Three hundred and seventy-nine children referred by pediatricians at the Clinic of Developmental Delay at the Kaohsiung Medical University-Medical Center were tested using the SSDD-II, and about 1 week to 1 month later, they were tested again using the BSID-II. The results indicate that (1) the SSDD-II score increased as age increased, fitting the principle of developmental sequence. (2) The raw scores of the Mental and Motor scales of the BSID-II significantly correlated with the five subscales of the SSDD-II. (3) The three facet scale scores (language, cognitive and motor) of the BSID-II also significantly correlated with the five subscales of the SSDD-II. The SSDD-II has a high concurrent validity, and is a convenient scale to use to screen children for developmental delay in clinical practice in Taiwan.
