Test-retest reliability and validity of the Computerized Version of the Category Test-Young Children's Version
The primary focus of the research involved the reliability and validity of the Computerized Version of the Category Test-Young Children's Version (CVCT-YC). There were 56 elementary school children, ages 5-8 (24 females 42.9% and 32 males 57.1%) who participated in this study. The subjects were drawn from several YMCA after-school programs in northern Texas and the mean age was 6.78 years.
Statistical results indicated that the CVCT-YC is indeed statistically stable over time, specifically over three-week periods. The CVCT-YC was also found to correlate significantly with a psychometrically established measure of fluid reasoning: the Concept Formation Test, which originates as a subtest from the Woodcock-Johnson Tests of Cognitive Ability. This research also examined for significant relationships between particular populations and the results of either the CVCT-YC or Concept Formation assessments. This research examined for the possible effects of age, gender, hand dominance, ethnicity, income, mother's highest level of education, father's highest level of education, primary caregiver's marital status, and with whom the subject lives. None of the populations were found to exhibit a significant relationship with assessment scores.
