The Conners Kiddie Continuous Performance Test 2nd Edition™ (Conners K-CPT 2™) assesses attention deficits in children ages 4 to 7:11 years old. Based on the well-established Conners CPT paradigm, the Conners K–CPT 2 takes only half the time (7.5 minutes) to complete, making it more appropriate for younger children. Results from the measure can be used for clinical assessment,
early identification, and educational classification. The assessment can be also be used to evaluate treatment effectiveness by
administering the test before treatment and during treatment
to monitor change.
Key Features:
• Authored by Dr. C. Keith Conners, Ph.D, an internationally
recognized academic, clinician, researcher, and expert on ADHD
• Time efficient, taking only 7.5 minutes to administer
• New normative data, collected to standardize the Conners
K-CPT 2 scores
• New scores and scoring algorithms, developed to help
assessors pinpoint the exact nature of the child’s attention
problems
• Easy interpretation through redesigned computer-generated
reports that feature clear visuals and interpretive text
• Cost-effective as a screening device using an unlimited
software program or pay per use option (for one computer
per user license)
Key Areas Measured
- Inattentiveness
- Impulsivity
- Sustained Attention
- Vigilance
ReportsAssessment Reports provide detailed information about
scores from a single administration, presented both numerically and graphically. An individual's scores are compared to those in the normative sample and elevations at the
scale and subscale level are indicated.
Progress Reports compare the results of two to four
administrations for the same individual to measure
changes
over time. These reports are ideal to use when monitoring treatment and intervention effectiveness.
How To Use
Development of the Conners K–CPT 2 was based on a normative sample of 320 four- through seven-year-old children. The normative sample was stratified to match the U.S. Census on a number of key demographic variables including gender, age, region, race/ethnicity, and parental education level. An additional clinical sample of over 100 cases of children diagnosed with ADHD and other clinical disorders were also collected.
Reliability and Validity
Reliability
Internal Consistency
Split-half reliability estimates:
Median r= .87 to .89 across gender groups in norm sample
Median r = .86 to .89 across gender in clinical sample
Test-Retest:
Median r= .57
Interval between test administrations: 8 to 34 days
Validity
Discriminative Validity (analysis of variance):
Conners K-CPT 2 accurately discriminates between clinical and non-clinical groups. Both an ADHD sample and a clinical non-ADHD sample scored higher than the general population sample on the majority of the Conners K-CPT 2 scores.
Incremental Validity:
Including Conners K-CPT 2 as part of a battery of assessments contributes to a more accurate prediction of clinical conditions. Adding the Conners K-CPT 2 to a broadband emotional and behavioural rating scale (Conners EC-P) increases the ability to predict group membership (ADHD) versus general population groups.
