The sample consisted of 304 children (141 boys, 163 girls) 3- and 4-yr.-old and enrolled in Head Start. A principal component analysis with a varimax rotation was conducted and two- and three-factor solutions were extracted. A two-factor solution produced a clear interpretive structure representing Fowler and Park's 1979 Aggressive-Hyperactive-Distractible and Anxious-Fearful factors. Even though a three-factor solution was statistically appropriate, extracting more than two factors yielded dimensions difficult to interpret. Examination of subscale differences among ethnic groups indicated significant group effect for ethnicity. Further examination showed that Euro-American children are rated significantly higher on the Anxious subtest than Latino, African-American, and Asian children, but there were no other subscale differences. Clinical and research implications are discussed.
