First-, second-, and third-order factors from the Children's Behavioral Classification Project Instrument and an attempt at rapprochement.

This article consists of two parts. The first part describes first-, second-, and third-order factor analyses of the responses of 1,278 parents to the Children's Behavioral Classification Project (CBCP) instrument. At the first order, 30 factors were derived, 26 of which matched factors from an earlier study with 341 subjects. At the second order, 9 factors were found, and at the third order, two forms of the well-known conduct problem and personality problem factors that could not be reduced by a fourth-order factoring were revealed. The second part of the study demonstrated convergencies among factors derived from the CBCP instrument and the factors, syndromes, or diagnostic categories of other instruments. Of the first-order CBCP factors, 14 appear to match the "narrow band syndromes" of Achenbach and Edelbrock's historic review. At least 7 of Sines' behavioral factors and 12 of Wirt et al.'s Personality Inventory for Children dimensions parallel the first-order CBCP factors; similarly, from 16 to 24 DSMIII categories appear to be fair matches. All but one of Stott et al's Bristol Social Adjustment Guides syndromes are matches for CBCP second-order factors. Finally, Quay's four major patterns appear to be counterparts of the third-order CBCP factors, as do Achenbach and Edelbrock's "broad band" factors and major DSM-III categories.
