Item level validity of the Devereux Elementary School Behavior Rating Scale.

Abstract

Using a random sample of children in grades one through six as well as a sample of children referred for social or emotional problems, the item level validity of the Devereux Elementary School Behavior Rating Scale was assessed. Results indicated that Devereux responses for “normal” children tended to be skewed, with the item means falling near the positive end of the response continuum and with narrow standard deviations. Item means in the referred sample were closer to the center of the distribution and tended to have larger standard deviations. When item-to-subscale correlations were considered, the Devereux items, in general, were significantly correlated with their home subscale. Thirty-two of the 45 items on the scale had home scale correlations that were significantly higher than any other subscale correlation for that item. K-R 20 coefficients for subscales ranged from .74 to .89. Because the 9 items that had very poor subscale correlations were clustered on 4 of the 11 original subscales, it was recommended that these subscales be eliminated. The result would be a 31-item scale that measures seven different factors.
