Latent structure of the Children's Category Test at two age levels in the standardization sample.

The latent structure of the Children's Category Test (CCT; Boll, 1993) was evaluated in the standardization sample, with separate principal factor analyses for the younger subgroup (ages 5-8 years; CCT-1) and the older subgroup (ages 9-16 years; CCT-2). At both age levels, a two-factor solution was found. It is concluded that the CCT is a multifactorial instrument, and that clinical interpretation should consider the diversity of dimensions assessed by this test.
