K–CPT™ V.5
Conners’ Kiddie Continuous Performance Test Version 5

C. Keith Conners, Ph.D.

Technical Information

The normative sample for the K–CPT included 454 children between the ages of 4 and 5. 314 of these children were classified as nonclinical, 100 were classified as clinical with ADHD, and 40 were classified as nonADHD clinical.

The K–CPT research results provide support for the psychometric soundness of the K–CPT for use as a screening tool. Two types of reliability information are provided:

  • Split-half Reliability: The K–CPT shows adequate consistency in terms of split-half reliability.
  • Standard Error: The standard error measurement values show that scores from the instrument are a reasonable match to the true performance levels of respondents.
Statistical validation is provided to demonstrate that K–CPT scores are significantly different for the general population and clinical
groups. In addition, hit rates are provided to evaluate the classification accuracy of the test. The K–CPT has satisfactory accuracy
in terms of both false negatives and false positives. The results also suggest that the K–CPT can provide observational and descriptive support in clinical contexts. Back to the top
