What is the VADRS?

The Vanderbilt ADHD Diagnostic Rating Scale (VADRS), developed by Dr. Mark L. Wolraich and colleagues in 2003, is a standardized behavioral rating scale used to screen for symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) and common comorbid conditions in children. It was created in response to concerns that other commonly used behavior scales did not fully align with the diagnostic criteria outlined in the DSM-IV.

The version of the scale available in Creyos Health is the Vanderbilt ADHD Parent Rating Scale (VADPRS), designed specifically for use by parents of children ages 6 to 12.

Use in Clinical Settings

The VADRS is commonly used in pediatric and primary care settings as part of a multi-informant screening process for ADHD. It is a widely accepted tool due to its alignment with DSM criteria and its inclusion of symptom and performance indicators beyond attention and hyperactivity, such as mood, conduct, and school functioning.

How It Works

The parent-report version includes 55 items that cover:

• Core DSM-IV symptoms of ADHD (inattentive and hyperactive/impulsive subtypes)

• Symptoms of oppositional defiant disorder (ODD) and conduct disorder (CD)

• Indicators of anxiety and depression

• Academic and social functioning

Parents rate the frequency of each behavior over the past 6 months on a 4-point scale ranging from “never” to “very often.” Scores are then automatically tallied and interpreted within the Creyos platform.

The tool provides insight into whether diagnostic criteria are met for:

• Inattentive type ADHD

• Hyperactive/impulsive type ADHD

• Combined type ADHD
  ➤  It also highlights potential concerns for comorbid behavioral or emotional disorders when relevant cutoff thresholds are reached.

How It Relates to Cognition

ADHD frequently coexists with cognitive challenges, including difficulties with attention, working memory, and executive functioning. When paired with Creyos cognitive assessments, the VADRS provides a well-rounded picture—combining subjective behavioral ratings with objective cognitive data to support more informed clinical decision-making.

The VADRS is also a valuable complement to the ASRS, which assesses ADHD symptoms in adults.

Clinical Considerations

The VADRS is a validated, research-backed screening tool, but it is not diagnostic on its own. A trained clinician should interpret results in the context of additional clinical interviews, teacher input (if applicable), developmental history, and cognitive assessments. The scale should be used as part of a comprehensive evaluation process.
