Multi-Rater Reports

Conners 4 measures symptoms and impairments associated with ADHD and common co-occurring problems and disorders in youth. Information is collected from multiple sources, including one or more parents/guardians (using the Parent form), one or more teachers (using the Teacher form), and the youth themselves (using the Self-Report form). The multi-rater report highlights potentially important inter-rater differences in scores.

The Conners 4 Multi-Rater report combines the results of up to five raters to provide an overview of the youth’s behaviour from a multi-rater perspective. It is available for the full-length Conners 4, Conners 4–Short, and the Conners 4–ADHD Index.

Integrating information from multiple raters ensures a more comprehensive assessment of youth being evaluated than what a single rater provides. The frequency and intensity of reported symptoms and associated features of ADHD can vary based on the environment and context, as well as the interactions with the individual. By comparing scores from different raters, one can better understand how these behaviors manifest in various situations and from different viewpoints. The Conners 4 Multi-Rater report facilitates this process by providing 
the results of multiple raters in one report, highlighting statistically significant inter-rater differences in scores and any critical areas that need further examination.

To access more information on the Multi-Rater report, refer to chapters 1 (Introduction) and 3 (Scoring and Reports) of the Conners 4 digital manual.
