VALIDADE CONCORRENTE E CONCORDÂNCIA ENTRE OS TESTES ALBERTA INFANT MOTOR SCALE E BAYLEY SCALES OF INFANT DEVELOPMENT-THRID EDITION EM PREMATUROS BRASILEIROS COM TRÊS MESES DE IDADE GESTACIONAL CORRIGIDA

Abstract

Objective: To compare the results with the Scale of Alberta (Alberta Infant Motor Scale), applied at three months of corrected gestational age (IGC), with those Scale Bayley (Bayley Scales of Infant Development - 3rd edition) in premature infants, discharged from the Neonatal Intensive Care Unit-NICU of University Hospital Maternal Child Unit - UFMA. Methods: We studied 42 premature infants in the outpatient clinics ("Follow up") Unit, University Hospital Maternal Child Unit - UFMA between March and August 2009. In the study of concurrent validity and agreement of the 42 premature infants at 3 months of IGC were assessed by AIMS and the motor scale of the Bayley Scales of Infant Development, 3rd edition, using the correlation coefficient of Pearson and the concordance test Bland & Altman to analyze the results. Results: In the study of concurrent validity, correlation found between the two scales was high (r = 0.86) and statistically significant (p <0.01) in the total population of infants. In concordance analysis showed that most of the measures is in the range between ± 1.96 standard deviation is thus the two tests agree. Conclusion: The AIMS is a valid and consistent with the standard measures can be recommended for evaluation of motor development of premature infants in the population of public health in Brazil.
