A further validation of the children's behavioral classification project inventory

To add evidence of the validity of the Children's Behavioral Classification Inventory, the response of parents and teachers were compared on a set of 110 items of the inventory which describe behaviors equally observable to both groups. The two sets of data were subjected in Phase I to principal components analysis to extract two factors in each case which were compared by means of the Ahmavaara transformation and found to be highly comparable. In Phase II, predictions were made from factor weights of 36 items measuring six factors in the original standardization of the inventory to both sets of respondents' data by means of confirmatory factor analysis. The formal indices of comparability were not generally in acceptable ranges; however, substantively the six factors were definitely replicated in the two samples.
