The Vanderbilt ADHD Diagnostic Parent Rating Scale is used to help in the diagnostic process of Attention Deficit/Hyperactivity Disorder (ADHD) in children between the ages of 6 and 12.
It has a total of 55 questions, includes all 18 of the DSM criteria for ADHD and should be completed by a parent of the child.
The teacher rated version can be used in parallel: Vanderbilt ADHD Diagnostic Teacher Rating Scale (VADTRS).
As well as identifying inattentive, hyperactive/impulsive, or combined subtypes of ADHD, it can also be used to identify symptoms of frequent comorbidities, including oppositional defiance, conduct disorder, anxiety and depression.
Concurrent validity has been established through comparing parent rating with teacher ratings and those independently diagnosed with ADHD (Mark et al., 2003). Confirmatory factor analysis confirmed four factors that fitted with the theoretical formulation of inattention, hyperactivity/impulsivity, ODD-CD, and anxiety-depression subscales.
Becker et al. (2011) validated the subscales but reformulated the scoring method for the comorbid sub-scales by using the total sum of scores. In this scoring system the total sum of the subscales (rather than when a parents rates either 2 or 3 on the Likert scale), ODD is ruled out at <10, CD at <4, Anxiety at <5 and Depression at <5. Nevertheless, the overall scale was validated and found to have high reliability and clinical utility.
Scores are presented for the three subtypes of ADHD:
Percentiles are presented (based upon the age of the child) comparing the respondent’s scores to those of a community sample of 1,570 parents in the USA (Anderson et al., 2022). A percentile of 50 indicates average (and healthy) functioning, and higher percentiles indicate more reported difficulties. For example, a percentile of 90 indicates the parent reports more problems for their child that 90 percent of other parents.
In addition to the ADHD scales, scores are presented for frequently comorbid difficulties. Children with scores below the clinical cutoff are highly unlikely to meet the diagnostic criteria for that disorder. Children above the cutoff on the ODD, CD, Anxiety/Depression sub-scales should be further evaluated, as these sub-scales are only designed as a cursory screening measure for such problems.
