Comparing the Ddst-Ii and Asq in Motor Development Domains of 4-60 Months Old Children in Tehran City

This research was made for screening the motor developmental status) fine and gross) of 4-60 months old children in Tehran city through Denver Developmental Screening Test II (DDST-II) and Ages and Stages Questionnaires (ASQ), comparing the results of two tests and determining their agreement coefficient. In this analytical study the gross and fine motor developmental status of 197 children 4-60 months old were screened by using ASQ and DDST-II in 4 primary health care clinics in north, south, east and west areas of Tehran. Convenient sampling was used. Data was analyzed and consistency coefficient of two tests was determined. By using ASQ and DDST-II fine motor developmental delay suspected in %5 and 11.7% of children and gross motor developmental delay suspected in 3.6% and 11.2% respectively. The estimated consistency coefficient between DDST-II and ASQ for fine motor domain was 0.05 and 0.24for gross motor domain. In this study motor developmental screening of children showed different results and kappa measure agreement of two tests was weak. For selecting a suitable tool it is necessary to compare the developmental screening results with a gold standard diagnostic test results of motor developmental screening be compared with a diagnostic gold standard test.
