Conners 4 is a well-validated and trusted tool that provides a comprehensive evaluation of ADHD and continues to evolve with new research.

Conners 4th Edition (Conners 4™) is the highly anticipated revision of the Conners 3rd Edition (Conners 3®), the world's leading Attention-Deficit/Hyperactivity Disorder (ADHD) assessment.

Conners 4 provides a comprehensive assessment of symptoms and impairments associated with ADHD and common co-occurring problems and disorders in children and youth aged 6 to 18 years. The Conners 4 is an inclusive and fair measure that builds on the long history and strengths of the multi-informant Conners Rating Scales. Conners 4 will be an invaluable part of your ADHD assessment battery with updated norms, improved workflows, and new and improved features.

Your purchased online forms can be used for any of the Conners 4 forms (Conners 4, Conners 4-Short, Conners 4-ADHD Index).

All purchases include free access to the Conners 4 Manual (via your account). You can also access it here - Conners 4 Manual.

Your purchased online forms can be used for any of the Conners 4 forms (Conners 4, Conners 4-Short, Conners 4-ADHD Index):

Conners 4

This form is the most comprehensive and is recommended for use in initial evaluations and full re-evaluations.​ This form includes all Conners 4 items and scales. ​

  • Parent and Teacher (6–18 years): Conners 4 Parent: Full Length, 117 items; Conners 4 Teacher: Full Length, 109 items.
  • Self-Report (8–18 years): Conners 4 Self-Report: Full Length, 118 items.

Conners 4–Short

This form is useful when a rater has limited time, or when the rater will be asked to complete the Conners 4 repeatedly (e.g., monthly assessment of treatment response).​ This form takes less time to complete than the full-length form but is not as comprehensive because it has fewer scales and fewer items per scale (for both Content and Impairment & ​Functional Outcome scales).​

  • Parent and Teacher (6–18 years): Conners 4 Parent: Short, 53 items; Conners 4 Teacher: Short, 49 items.
  • Self-Report (8–18 years): Conners 4 Self-Report: Short, 51 items.

Conners 4–ADHD Index

This index can be used as a screener to determine which youth are most likely to require a more comprehensive evaluation.​ The Conners 4–ADHD Index contains 12 items from the full-length form that best differentiate youth diagnosed with ADHD from youth in the general population. ​

  • Conners 4 ADHD Index Parent, Teacher: 12
  • Conners 4 ADHD Index Self-Report: 12

All Conners 4 Forms provide a Single Rater Report. The Single Rater Report provides detailed information about scores from a single administration, presented numerically, graphically, and within an interpretive summary. A youth’s scores are compared to those in one or more Normative Samples, and optionally, to an ADHD Reference Sample. Also includes a Within-Profile Comparison of the youth’s results to their own average score. Elevations at both the scale and item level are included. Key results are provided in a one-page overview.

All Conners 4 users receive access to a free, digital version of the Conners 4 Manual.

Multi-Rater reports are now available for Conners 4.

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 on MAC+.
