The objective of this study was to examine the psychometric properties of the Spanish version of the Denver Developmental Screening Test II in a population of Spanish children. Two hundred children ranging from 9 month to 6 years were grouped into two samples (healthy/with psychomotor delay) and screened in order to check whether they suffered from psychomotor delay. Children from three Early Intervention Centres and three schools participated in this study. Criterion validity was calculated by the method of extreme groups, comparing healthy children to those with development delay. Interobserver and intraobserver reliability were calculated using Cohen Kappa coefficient, and internal consistency was calculated via the Kuder-Richardson coefficient. The scale demonstrated 89 % sensitivity, 92 % specificity, a positive predicted value of 91 % and a negative predicted value of 89 %, whereas the positive and negative likelihood ratio was 11.12 and 0.12, respectively. Intraobserver reliability ranged from 0.662 to 1, and interobserver reliability ranged from 0.886 to 1. The Kuder-Richardson coefficient values ranged from 87.5 to 97.6 %.
Conclusion: The Spanish version of the Denver Developmental Screening Test II was found to have a good criterion validity, reliability and internal consistency and is a suitable screening test for use in a population of Spanish children.
