PASCUCCI, MC et al. Validation for screening test of detecting psychomotor development problems in children under six. Rev. bol. ped. [online]. 2004, vol.43, n.3, pp. 193-193. ISSN 1024-0675.
The use of a screening test in the first years of life allows the early detection of delays of psychomotor development and its treatment, thus contributing to improve the prognosis of the child with special needs. In Argentina, a screening test for detecting developmental problems in children under 6, made with local children and data is available (PRUNAPE). A validation procedure for this test was carried out on 106 children attending at low risk outpatient clinic in Hospital Garrahan. The test was administered to the children together with a battery of diagnostic examinations and studies, performed by experienced specialists from different Hospital services: psychomotor development, neurology examination, mental health, intellectual quotient (Wechsler, Terman), adaptive behaviour (Vineland), language (Gardner expressive and receptive, ITPA), hearing (otoacustic emissions, audiometry, BERA), vision. The DSM IV was used as a reference for developmental problems. Using as a failure criterion to the PRUNAPE, the failure of performing correctly one type A item or two type B item, sensitivity of the test was 80%, specificity, 93%; positive predictive value, 95%; negative predictive value, 77%; overall agreement, 85%. A very high prevalence of developmental problems was found: 57%. PRUNAPE was found to be capable of detecting a wide range of problems. These results confirm PRUNAPE as a valuable instrument for early detection of developmental problems in paediatric practice at the primary care level.
