The Vanderbilt Assessment Scales (VAS) are used by health care professionals to help diagnose ADHD in children between the ages of 6- and 12-years. They include parent, self, and teacher-report versions. The scale is particularly helpful for collecting data from multiple sources and assessing academic and behavior performance. It can also be used to establish baselines, measure treatment effectiveness, and has utility to screen for comorbid disorders.
Parent-report, self-report, and teacher-report versions
The VAS produces a composite score, as well as subscale scores, automatically through the Blueprint platform. Scores can be used to assess the severity of ADHD symptoms and track change across the course of treatment.
The scale has good internal reliability with Cronbach’s alpha coefficient of > .90 (parent) and >.89 (teacher) (Wolraich et al., 2002; Wolraich et al., 2013). Test-retest reliabilities were assessed as adequate (r >.80) (Bard et al., 2013). Interrater reliability, between the two scales is very low (r=.27 – .34) (Wolraich et al., 2002). The four factor structure of the scale confirms it is a valid measure of inattention, hyperactivity, conduct disorder/oppositional defiance disorder, anxiety/depression. Convergent validity is evidenced by the moderate to high correlations with the Diagnostic Interview Schedule for Children-IV Parent Version (Bard et al., 2013; Collett et al., 2003).
