Reliability
The Conners 4 Parent, Teacher, and Self-Report scale have excellent internal consistency (median omega coefficient = .94), strong test-retest reliability (median r = .89), and moderate to strong inter-rater reliability (median r = .84 for two parent raters; median r = .52 for two teacher raters).
Test Validity
Results from confirmatory factor analyses (CFA) provided evidence to support the structure of the Conners 4 scales (6-factor model for the Content Scales [CFI = .940, RMSEA = .051]) and 3-factor model for Parent and Self-Report and 2-factor model for Teacher for the Impairment Functional Outcome Scales [CFI = .935; RMSEA = .094]).
Please contact us if you would like to know more about the convergent or criterion related validity of the Conners 4.
Norms
A total of 3,120 youth were included in the Normative Samples (N = 1,560 for Parent; N = 1,560 for Teacher; and N = 1,100 for Self-Report). Combined gender norms are provided for youth in 1-year age intervals; separate norms for males and females are also available.
