An assortment of additional cases (Anxiety and Depression) were also included. Reliability
Two types of reliability information—Split half Reliability and Standard Error— provide support for the psychometric soundness of the CPT II test. The CPT II test shows adequate consistency in terms of Split-half Reliability, and the Standard Error measurement values show that scores from the instrument are a reasonable match to the true performance of individuals.it-half Reliability: The K–CPT shows adequate consistency in terms of split-half reliability.
