Resumo

LOPES, Sónia et al. Estudo exploratório do instrumento Ages & Stages Questionnaires: 2ª edição. Aná. Psicológica [online]. 2011, vol.29, n.1, pp.149-166. ISSN 0870-8231.

The Ages and Stages Questionnaire 2nd edition (ASQ-2) was designed to screen developmental delays, identifying the need for more specific assessments. The ASQ-2 study with a sample of Portuguese population (n=339) was conducted with the aim of observing its psychometric qualities and with this intent it was translated and culturally adaptate for the Portuguese population. The study of the psychometric qualities of the ASQ-2 in its Portuguese version revealed that for sensitivity the values of kurtosis and skewness, by and large, are close to a normal distribution; for reliability, the Cronbach’s coefficient alpha values for the totals vary between 0,70 and 0,75, showing reasonable internal consistency, significantly improving when observed with split-half varying between 0,83 and 0,88, showing good internal consistency; for validity the r de Pearson values for totals indicate significant correlations in most of the areas in the different questionnaires. We conclude that the results obtained are an incentive to proceed with the validation of the ASQ-2 for the Portuguese population, thereby, contributing to fill the gap that exist presently, considering validated developmental assessment instruments for Early Intervention.
