Conners Continuous
Performance Test 3rd Edition™
How it works The Conners CPT 3™ is a task-oriented computerized assessment of attention-related problems in individuals aged 8 years and older. During the 14-minute, 360-trial administration, respondents are required to respond when any letter, except “X”, appears. By indexing the respondent’s performance in areas of inattentiveness, impulsivity, sustained attention, and vigilance, the Conners CPT 3 can be a useful adjunct to the process of diagnosing Attention-Deficit/Hyperactivity Disorder (ADHD), as well as other psychological and neurological conditions related to attention.
Comprehensive Dimensions of Attention
New scores and scoring algorithms have been developed to help Formats: assessors pinpoint the exact Software nature of the respondent’s attention problems. The Conners Qualifications: CPT 3 uses both standardized B and raw scores to determine not only the respondent’s performance overall but also in four different aspects of attention: Inattentiveness, Impulsivity, Sustained Attention and Vigilance.

CPT 3 ™
Conners Continuous Performance Test 3™
Please see reverse for Reliability & Validity for Conners CATA
Reliability Users can be confident that the Conners CPT 3 will yield consistent and stable scores across administrations.
Internal Consistency One measure of a test’s internal consistency is split-half reliability, which has been previously used to establish the reliability of other continuous performance tests. Split-half reliability estimates of the Conners CPT 3 scales were calculated for the normative and clinical samples. Results were very strong – across all sccores, the median split-half reliability estimate was .92 for the norm samples, and .94 for the clinical samples (all correlations were significant, p < .001). These results indicate that the Conners CPT 3 demonstrates excellent internal consistency for both the normative and the clinical groups.
Test-Retest Reliablilty
Test-retest reliability refers to the consistency of scores obtained from the same respondent on separate occasions over a specified period of time. To estimate the test-retest reliability of the Conners CPT 3, a sample of 120 respondents from the general population completed the Conners CPT 3 twice with a 1- to 5-week interval between administrations. The median test-retest correlation was .67. These results suggest a good level of test-retest reliability.
Validity Users can be assured that the Conners CPT 3 will help detect attention deficits and differentiate Clinical from Non-Clinical Cases.
Discriminative Validity Discriminative validity pertains to an instrument’s ability to distinguish between relevant participant groups (i.e., the test’s ability to differentiate between clinical and non-clinical groups). In order to conduct discriminative validity analyses, Conners CPT 3 data were collected during the standardization process from 346 children and adults who had an existing ADHD diagnosis. Conners CPT 3 scores from this ADHD sample were compared to a matched sample from the general population. Results indicated that significant differences were found between the ADHD sample and the matched general population sample on most measures with small to moderate effect sizes (d = 0.10 to 0.49). As expected, the ADHD sample performed more poorly (i.e., they had higher scores on the Conners CPT 3). In particular, the ADHD sample had lower d’ scores, indicating more difficulty in distinguishing between relevant stimuli and distractors. Similarly, the ADHD sample made a greater number of errors (i.e., they had higher percentages of Omissions, Commissions and Perseverations than did the general population sample) and showed more variability in their responses overall (i.e., higher HRT SD scores) and across subblocks (i.e., higher Variability scores) compared to the matched sample of general population. The responses of the ADHD sample were also affected more by changes in block and ISI (i.e., higher HRT Block Change and HRT ISI Change scores).
Incremental Validity Another approach in establishing the Conners CPT 3’s validity is to show how it works together with other measures of similar constructs in the assessment of attention problems. To assess such validity, samples were collected in which cases were scored on the Conners CPT 3 and another measure of attention. Specifically, in a sample of 112 non-clinical and ADHD youths, parent-reports on the Conners 3rd Edition (Conners 3-P; Conners, 2008) were collected in addition to their scores on the Conners CPT 3. In a second sample of 137 non-clinical and ADHD adults, self-reports on the Conners Adult ADHD Rating Scales (CAARS; Conners, Erhardt, & Sparrow, 1999) were collected in addition to their scores on the Conners CPT 3. Logistic regressions were conducted in order to determine how well scores from the Conners CPT 3 improve the diagnostic efficacy of the rating scales in predicting group membership into ADHD or general population groups. For youth, when the Conners 3-P and Conners CPT 3 scores were considered together, there was an overall correct classification rate (i.e., the ability to accurately predict group membership) of 88.4%, sensitivity (i.e., the ability to correctly detect ADHD cases) of 89.5%, and specificity (i.e., the ability to correctly detect general population cases) of 87.3%. These values were 4.5%, 3.5%, and 5.5%, respectively, higher than when the rating scale was used on its own. For adults, when the CAARS and Conners CPT 3 scores were considered together, the overall correct classification rate was 92.7%, sensitivity was 73.1%, and specificity was 97.3%. These values were 3.6%, 7.7%, and 2.7%, respectively, higher than when the rating scale was used on its own. These results indicate that adding the Conners CPT 3 to scores from rating scales increases the ability to predict group membership. Conners 3-P

Auditory Test of Attention®
How it works The Conners CATA® assesses auditory processing and attention-related problems in individuals aged 8 years and older. During the 14-minute, 200-trial administration, respondents are presented with high-tone sounds that are either preceded by a low-tone warning sound (warned trials) or played alone (unwarned trials). Respondents are instructed to respond only to high-tone sounds on warned trials, and to ignore those on unwarned trials. By indexing the respondent’s performance in areas of inattentiveness, impulsivity, sustained attention, auditory laterality, and auditory mobility, the Conners CATA can be a useful adjunct to the process of diagnosing Attention-Deficit/Hyperactivity Disorder (ADHD) and other neurological conditions related to auditory attention.

Split-half reliability estimates of the Conners CATA scales were calculated for the normative and clinical samples. Results were very strong – across all scores, the median split-half reliability estimate was .95 for the norm and clinical samples (all correlations were significant, p < .001).

Test-Retest Reliability Test-retest reliability refers to the consistency of scores obtained from the same respondent on separate occasions over a specified period of time. To estimate the test-retest reliability of the Conners CATA, a sample of 69 respondents from the general population completed the Conners CATA twice with a 1- to 4-week interval between administrations. The median test-retest correlation was .64. These results suggest a good level of test-retest reliability.
Validity Users can be assured that the Conners CATA will help detect attention deficits and differentiate Clinical from Non-Clinical Cases.
Discriminative Validity Discriminative validity pertains to an instrument’s ability to distinguish between relevant participant groups (i.e., the test’s ability to differentiate between clinical and non-clinical groups). In order to conduct discriminative validity analyses, Conners CATA data were collected during the standardization process from 193 children and adults who had an existing ADHD diagnosis. Conners CATA scores from this ADHD sample were compared to a matched sample from the general population. Results indicated that differences were found between the ADHD sample and the matched general population sample on most measures with small to moderate effect sizes (d = 0.10 to 0.63). As expected, the ADHD sample demonstrated poorer performance (i.e., they had higher scores on the Conners CATA). In particular, the ADHD sample had lower d′ scores, indicating that they had more difficulty in distinguishing between target trials and non-target trials than did the general population sample. Similarly, the ADHD sample made a greater number of errors (i.e., they had higher percentages Commissions and Perseverative Commissions than did the general population sample) and showed more variability in their responses (i.e., higher HRT SD scores, when compared to the matched general population sample).
Incremental Validity Another approach in establishing the Conners CATA’s validity is to show how it works together with other measures of similar constructs in the assessment of attention problems. To assess such validity, samples were collected in which cases were scored on the Conners CATA and other measures of attention. Specifically, in a sample of 112 youth, parent-reports on the Conners 3rd Edition (Conners 3-P) were collected in addition to their scores on the Conners CATA and the Conners CPT 3. Logistic regressions were conducted in order to determine how well scales from the Conners CATA improve the diagnostic efficacy of the Conners 3-P and Conners CPT 3 in predicting group membership into ADHD or general population groups. Results are presented in the table below. When the Conners 3-P, Conners CPT 3, and Conners CATA scores were considered together, there was an overall correct classification rate (i.e., the ability to accurately predict group membership) of 93.8%, sensitivity (i.e., the ability to correctly detect ADHD cases) of 94.7%, and specificity (i.e., the ability to correctly detect general population cases) of 92.7%. These values were 9.9%, 8.7%, and 10.9%, respectively, higher than when the rating scale was used on its own.
