The principal investigator interviewed consenting youth and parents, seeking endorsement of the symptoms of CD from either person, as well as further demographic information before administration of the CPT-II. The presence of CD was determined using the criteria for this disorder identified by the Diagnostic and Statistical Manual of Mental Health Disorders, Fourth Edition, Text Revision (DSM-IV-TR, 2000). The CPT-II performance of 34 youth with CD was compared to that of 35 youth who were members of the control group. Since research has shown a strong co-occurrence of CD with ADHD, with some authors reporting it to be as high as 90%, it was important to examine how a group of youth with CD would perform on this instrument and what characteristics of executive functioning might influence these results. The CPT-II is an instrument commonly used to assess for the presence of ADHD. The purpose of this study was to investigate neuropsychological factors related to performance on the Conners' Continuous Performance Test, Second Edition (CPT-II) among youth who met criteria for Conduct Disorder when compared to a control group of youth who did not meet criteria for Conduct Disorder (CD). One of the primary advantages of this paradigm is the high proportion of targets that appear, yielding a larger pool of responses for generating the statistical output. Over the duration of the test, 324 non-X stimuli (i.e., targets) appear, and the letter “X” (nontarget) appears 36 times. Respondents are instructed to press the spacebar or the appropriate key on the mouse for any letter that appears, except the letter “X.” The CPT takes fourteen min to administer excluding the recommended practice test. The ISIs are counterbalanced across these blocks. The 360 trials are divided into 18 blocks of 20 trials each. The Conners CPT-2 presents 360 stimuli trials (i.e., individual letters) on the screen, with 1, 2, or 4 s between the presentation of letters (ISI: Inter-Stimulus Interval).

The Conners Continuous Performance Test - 2 (CPT-2 Conners, 2000) is a computer administered test that is designed to assess problems with attention.
