Purpose: A thorough assessment of attention-deficit/hyperactivity disorder (ADHD) and its most common comorbid problems and disorders in children and adolescents aged 6 to 18 years.
Time: 10-20 minutes
Qualification Level: B
The Conners 3rd Edition™ (Conners 3®) is a thorough assessment of attention-deficit/hyperactivity disorder (ADHD) and its most common comorbid problems and disorders in children and adolescents aged 6 to 18 years. It is a multi-informant assessment that takes into account home, social, and school settings, with rating forms for parents, teachers, and youth. School psychologists, clinicians, psychiatrists, pediatricians, child protection agencies, and mental health workers can count on the Conners 3 to be a reliable and dependable tool capable of supporting them in the diagnostic and identification process.
- Inform your ADHD diagnosis with results that have direct connections to DSM-5 symptom criteria and IDEIA legislation
- Develop informed intervention and treatment strategies by identifying specific challenge areas to work on
- Monitor response to intervention and its effectiveness with detailed progress reports
- Assess common comorbid disorders (Oppositional Defiant Disorder and Conduct Disorder) to assist with differential diagnosis
- Discover how ADHD symptoms are affecting the youth by looking at impairment items which indicate functioning in home, school and social settings
- Spend less time on paperwork and more time with the youth with fast and easy to use administration and scoring, and easy to interpret reports
- Gain a multi-rater perspective of the youth’s difficulties with a Parent, Teacher, and Self-report version
Key Areas Measured
Assessment 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.
Comparative Reports combine the results of different raters to provide an overview of an individual's scores from a multi-rater perspective. This highlights potentially important inter-rater differences in scores.
Both test-retest reliability and internal consistency are very good for the Conners 3 scales and indices. Internal consistency coefficients for the total sample range from .77 to .97, and 2- to 4-week test-retest reliability coefficients (Cronbach's alpha) range from .71 to .98 (all correlations significant, p < .001). Inter-rater reliability coefficients range from .52 to .94.
Support for the validity of the structure of the Conners 3 forms was obtained using factor analytic techniques on derivation and confirmatory samples. Convergent and divergent validity were supported by examining the relationship between Conners 3 scores and other related measures. Statistical examination of the ability of the Conners 3 to differentiate youth with ADHD from youth in the general population and from youth in other clinical groups (including those with Disruptive Behavior Disorders and Learning Disorders) strongly supported the measure’s discriminative validity.
