comparing the results of developmental screening of 4 to 60-month-old children in tehran using parents evaluation of developmental status and ages and stages questionnaires

Objectives: this research was designed to evaluate the developmental status of children aged 4 to 60 months in tehran city by two parent-based developmental screening questionnaires, parents evaluation of developmental status (peds) and ages and stages questionnaires (asq), and also to determine the consistency coefficient between these two tests. methods: in this cross-sectional study, peds and asq were performed on 648 children (350 boys and 298 girls), aged 4 to 60 (mean, 23.5 ± 16.10) months at four health centers in tehran city. results: developmental disorders were observed in 23.1% of children (4.6% delayed and 18.5% suspicious), who were examined by peds, and in 26.4% of children, who were examined by asq (14.7% delayed and 11.7% suspicious). the estimated values of kappa measure of agreement and pearson chi-square for the results of the two screening tests were 0.30 (p < 0.001) and 115.98 (p < 0.001), respectively. the results of these tests were similar in 93.3%, 94% and 91% of cases in fine motor, gross motor and language domains of development, respectively. due to the rather large sample size and similarity of the screening results by both questionnaires in 71.5% of cases, it is possible to conclude that this measure is an acceptable one. conclusions: this study showed that peds and asq have acceptable agreement, thus it seems that peds can be used for children’s developmental screening especially in child care visits.
