E N D
Revision of the CRS-R • Thorough assessment of attention-deficit/hyperactivity disorder (ADHD) • Comprehensive Behavior Rating Scales (CBRS) • Covers a broad range of childhood disorders and problems
Conners:Responding to Assessment Trends • First: Broad-band assessment used to identify suspected and unknown areas of concern (Conners CBRS). • Second: Once the areas of concern have been identified, a narrow instrument is used to confirm the diagnosis (Conners 3).

Conners 3 • Streamlined and refined revision of CRS-R • An in-depth, focused assessment of ADHD • Informs differential diagnosis by assessing and screening for problems and disorders most commonly comorbid or associated with ADHD • Stratified and representative of U.S. population (2000)
Key Changes From CRS-R • Streamlined content • New normative data and updated psychometric properties • Modified age range • Increased similarities across forms • Respondent-friendly translations ofDSM-IV concepts
Key Changes From CRS-R (cont.) • Shifted some CRS-R content to Conners CBRS • Anxious/Shy, Perfectionism, and Psychosomatic • Conners-Wells’ Adolescent Self-Report Scale(CASS) Emotional Problems • New scale and item-level content • DSM-IV symptoms of oppositional defiant disorder (ODD) and conduct disorder (CD) • Assessment of executive functioning (parent andteacher forms) • New validity scales (PI, NI, and IncX) • Screener items for anxiety and depression • Severe conduct critical items • Impairment items
Key Changes From CRS-R (cont.) • Short form content • No more Conners ADHD/DSM-IV Scales (CADS) • CASS has been renamed the self-report • ADHD index available as separate 10-item index • The Conners 3 Global Index features the same items with new norms
Conners 3Full-Length Forms • Recommended for use when comprehensive information and DSM-IV symptoms are required • Parent (ages 6-18 years), teacher (ages 6-18 years), and self-report (ages 8-18 years) • 110 items for parent, 115 for teacher, and 99 items for self-report • Ratings are based on the past month • The scales of the three forms closely parallel each other
Conners 3 DSM-IV scales ADHD Hyperactive/Impulsive ADHD Inattentive Conduct Disorder Oppositional Defiant Disorder Validity scales Negative Impression (NI) Positive Impression (PI) Inconsistency Index (IncX) Conners ADHD Index (3AI) Conners3 Global Index (3GI) (parent, teacher) Screener items anxiety, depression Impairment questions Severe conduct critical items
Conners 3Short Forms • Useful when administration of the full-length versions is not possible or practical • Subset of items from the full-length form, representing concepts from all empirical scales, the rational inattention scale, and the validity scales • Parent (ages 6-18 years), teacher (ages6-18 years), and self-report (ages 8-18 years) • Ratings are based on the past month • The scales closely parallel each other
Conners 3 Short Forms (cont.) Validity scales: Negative Impression + Positive Impression
Conners 3AI • A 10-item index within the full-length forms • Also available as a separate, brief, ADHD-focused measure • Items selected as the best to differentiate peoplewith ADHD from individuals with no clinical diagnosis • Useful as a quick check to see if further ADHD evaluation is warranted • Can also be useful for repeated measures • Available for parents, teachers, and as a self-report
Conners 3GI • An index within the Conners 3 full-length forms • Also available separately as a quick measure of general psychopathology • Same items, new norms • Useful in determining which direction to take with further examination • Especially useful for monitoring treatment effectiveness and changes over time • Available for parents and teachers
Conners 3 Psychometrics
Norms: Age x Gender Age (years) Gender M F Parent total N = 1,200 (ages 6-18 years) Teacher total N = 1,200 (ages 6-18 years) Self total N = 1,000 (ages 8-18 years)
Ethnic Representation (%) Ethnic representation closely matches census figures.
Reliability • Positive and Negative Impression scales contain only six items each. The fewer the number of items, the lower alpha tends to be.1 • These scales are made up of items not typically endorsed. Therefore, variability of the items is compromised, resulting in lower alphas. • Given these considerations, the obtained alpha values for the validity scales are considered satisfactory. Why are internal consistency estimates of validity scales generally weaker than the remaining scales? 1 John, O. P., & Benet-Martinez, V. (2000). Measurement, scale construction, and reliability. In H. T. Reis & C. M. Judd (Eds.), Handbook of research methods in social and personality psychology (pp. 339-369). New York: Cambridge University Press.
Measuring Change • If we have implemented a treatment program and are measuring change, how do we know if the difference is significant or not? • Important consideration for RTI programs and evidence-based practice issues in health care • Jacobson and Truax method of calculating a reliable change index (RCI).2 How do I know if a change in Conners scores over time is statistically and/or clinically significant? 2 Jacobson, N. S., & Truax, P. (1991). Clinical significance: A statistical approach to defining meaningful change in psychotherapy research. Journal of Consulting and Clinical Psychology, 59, 12-19.
Reliable Change Index • RCI values are based on a 90% confidence interval. • A change in scores that meets or exceeds the RCI value can be considered to be a statistically significant change 90% of the time. • Liberal criteria were used to better ensure that important changes in scores are not missed.
Reliable Change Index: Example • Johnny’s teacher completed the form at time 1, then again 3 months into an intervention at time 2. • Johnny’s T score on the Hyperactivity/Impulsivity scale is 85 at time 1 and 75 at time 2 (a 10-point decrease). • The RCI value for the Hyperactivity/Impulsivity scale is 9.01. • Johnny’s 10-point decrease is considered statistically significant. • Clinical significance can be established by looking at what the change means in practical terms. In this case Johnny is still 2.5 standard deviations above the mean, suggesting little clinical significance.
Conners 3and the BRIEF A sample of participants completed both the Conners and the BRIEF. The results suggest that the two scales complement each other nicely and that an elevated score on the Executive Functioning scale on the Conners should be followed up with a full administration of the BRIEF to provide a clearer picture of executive functioning deficits.
Conners 3 andthe BRIEF (cont.) Hyperactivity/Impulsivity • Conners 3 Hyperactivity/Impulsivity Scale • - Correlates with BRIEF Inhibit scale = .76-.90 (p < .01) • Conners 3 DSM ADHD Hyperactive/Impulsive Scale • - Correlates with BRIEF Inhibit scale = .78-.92 (p < .01)
Conners 3 andthe BRIEF (cont.) Learning Problems/Executive Functioning • Conners 3 Executive Functioning (Teacher) • Correlates with BRIEF Plan/Organize scale = .87 (p < .01) • Correlates with BRIEF Organization of Materials scale = .75 (p < .01) • Conners 3 Executive Functioning (Parent) • Correlates with BRIEF Plan/Organize scale = .70 (p < .01) • Correlates with BRIEF Organization of Materials scale = .45 (p < .01)
Making the Transition:CRS-R to Conners 3 • CRS-R long and short forms (ages 3-17 years) • Conners 3 full-length and short forms (ages 6-18 years) • Conners Early Childhood (Conners EC) full-length and short forms (ages 2-6 years) • CADS (ages 3-17 years) • Not part of Conners 3 • Can use Conners 3AI (ages 6-18 years) in screening situations • If DSM-IV scores are required, you can use the full-length Conners 3 • Conners Global Indexes (ages 3-17 years) • Conners 3GI (ages 6-18 years) • Conners EC Global Index (ages 2-6 years)
