Conners’ Continuous Performance Test (2nd ed.; CCPT-II)

The Conners’ Continuous Performance Test (2nd ed.; CCPT-II; Conners, 2000) is a visual paradigm used for the evaluation of attention as well as the response inhibition component of executive control. It represents an effort to incorporate reliable and objective assessment into evaluations for ADHD and other neurological disorders. The updated version of the CCPT-II (Conners, 2000) differs from previous versions of the CCPT-II (Conners, 1992, 1995) in that it provides a validity test to identify invalid administrations, a confidence index (CI) score to assess the likelihood that the examinee’s responses fit those given by individuals with ADHD, new theory and methods for computing signal detection theory statistics, and new and expanded norms. Although improvements are commended, clinicians are encouraged to familiarize themselves with the manual and normative data and be mindful of limitations when interpreting results.
