The factor analytic structure of the Roberts Apperception Test for Children : a comparison of the standardization sample with a sample of chronically ill children

A confirmatory principal component factor analysis of the Roberts Apperception Test for Children was conducted using the standardization sample and a sample of chronically ill children. An interpretation of three- and four-factor solutions identified the three-factor solution as superior to the four-factor solution as measured by chi-square goodness of fit and coefficients of convergence. A cluster analysis using Ward's minimum variance method was calculated to determine the typical profiles that best describe the chronically ill sample. Results of this analysis reveal two distinct profiles that differ primarily on the level of adaptive psychological functioning.
