Factor analysis of the Intermediate Category Test.

This study examined the factor structure of the six subtests of the Intermediate Category Test in a heterogeneous sample of school-referred students, age 9 to 14 years. A three-factor solution emerged that accounted for approximately 72% of the total variance. This indicates that the test measures multiple underlying constructs in this school-referred sample. Clinical and educational interpretations may be enhanced by utilizing factor scores that reflect the multiple abilities assessed. Recommendations for developing factor/index scores are provided.
