Estudo de validação e reprodutibilidade de uma escala de silhueta para adolescentes Estudio de validación y reproductibilidad de la escala de silueta para adolescentes Study of validity and reliability of one contour rating scale to adolescence
Abstract
O objetivo deste estudo foi validar e confirmar a reprodutibilidade de uma escala de silhueta para adolescentes. Para tanto, pesquisou-se 386 jovens de uma Escola Particular de Ensino. Desenvolveram-se análises de validação de construto e reprodutibilidade. O instrumento foi capaz de discriminar os quatro grupos segundo estado nutricional (α2=30,5, pEl objetivo del estudio fue validar y confirmar la reproductibilidad de la escala de silueta para adolescentes. Participaron 386 jóvenes de una Escuela Particular de Enseñanza. Se evaluaron análisis de validación de construto y reproductibilidad. El instrumento fue capaz de discriminar los cuatro grupos según estado nutricional (α2=30,5, pThe aim of this study was to validate and verify the reliability of one contour rating scale. Therefore, were searched 386 teenagers of a private school. It was developed validity construct of analyses and reproducibility. The instrument was evaluated for construct analyses and reproducibility. The instrument was able to discriminate the four actual weight groups (α2=30,5, p<0,001; α2=19,3, p<0,001), correlated with the other three measures (IMC, RCQ e CC) researched (r=-0,61, p<0,001, r=-0,49, p<0,001, r=-0,54, p<0,001; r=-0,52, p<0,001, r=-0,23, p=0,001, r=-0,42, p<0,001) and confirmed its reliability by the coefficient of the interclass correlation (r icc=0,86, p<0,001; r icc=0,80, p<0,001) for boys and girls, respectively. In the comparison of means of the score scales (test-retest) were confirmed the reliability only for boys (p=0,86). The instrument performed well regarding verbal comprehension and time of completion. It was concluded that the contour rating scale presented goods results in the analysis of validity and reliability.
