ADHD Assessment Forms

The Vanderbilt ADHD Rating Scales (parent and teacher versions) are the primary screening tools recommended by the American Academy of Pediatrics for children ages 6-12 years, while the Conners Rating Scales are validated alternatives across all age groups including preschool, school-age, adolescents, and adults. 1

Primary Recommended Assessment Tools by Age Group

Children Ages 6-12 Years

  • The Vanderbilt ADHD Rating Scales are specifically recommended by the American Academy of Pediatrics as part of their comprehensive ADHD toolkit for elementary and middle school children 1
  • Both parent and teacher versions must be completed to gather information across home and school settings, as DSM-5 criteria require documentation of impairment in more than one major setting 1
  • These forms help clinicians diagnose ADHD and categorize the problem into its various presentations (inattentive, hyperactive-impulsive, or combined) 1

Preschool-Aged Children (4-5 Years)

  • The Conners Comprehensive Behavior Rating Scales and the ADHD Rating Scale IV are the only DSM-based scales validated for preschool-aged children 2
  • Assessment is particularly challenging in this age group because children may lack separate observers if not attending preschool or childcare 2
  • Focused checklists help physicians determine the presence of key symptoms when observation across multiple settings is limited 2

Adolescents (12-18 Years)

  • The Vanderbilt scales can be used to screen for ADHD, related behavior disorders, and general academic and behavioral performance 1
  • The Pediatric Symptom Checklist and Strengths and Difficulties Questionnaire are well-suited for screening from 48 months through adolescence 1
  • The Conners Rating Scale helps gather information from multiple teachers when adolescents have several instructors 1
  • Obtaining teacher reports is more challenging because adolescents have multiple teachers, and parents have less opportunity to observe behaviors than when children were younger 2

Adults

  • The Conners Adult ADHD Rating Scale (CAARS) is used to evaluate ADHD symptoms in adults 1
  • Self-report rating scales and observer report scales quantify ADHD symptoms using Likert scales, making them useful for following the course of the disease 3

Critical Implementation Requirements

Multi-Informant Assessment is Mandatory

  • Information must be obtained from multiple sources including parents, teachers, and other observers to verify that DSM-5 criteria are met 1
  • Both parent and teacher ratings are needed for clinical purposes, as this is the most efficient assessment method 4
  • Rating scales serve to systematically collect symptom information but do not diagnose ADHD by themselves 1

Comprehensive Evaluation Beyond Questionnaires

  • Rating scales alone have adequate sensitivity but poor specificity in diagnosing ADHD 5
  • A comprehensive evaluation must include clinical interviews with parents, direct examination and observation of the child, and documentation of functional impairment 1
  • Alternative causes for symptoms must be ruled out through clinical interview and examination 1

Mandatory Comorbidity Screening

  • The American Academy of Pediatrics recommends screening for common comorbid conditions that may alter treatment approach 1
  • Essential screening includes emotional/behavioral conditions (anxiety, depression, oppositional defiant disorder, conduct disorders, substance use) 1
  • Developmental conditions (learning and language disorders, autism spectrum disorders) and physical conditions (tics, sleep disorders) should also be assessed 1
  • The majority of children with ADHD meet criteria for another mental disorder, making this screening essential rather than optional 6

Common Pitfalls to Avoid

  • Relying solely on questionnaire scores without clinical interview and multi-informant data is a common pitfall 1
  • Failing to gather information from multiple sources and settings leads to incomplete assessment 1
  • Not screening for comorbid conditions that may complicate treatment or explain symptoms 1, 6
  • Assigning an ADHD diagnosis when symptoms are better explained by trauma, substance use, or other psychiatric conditions 6
  • Failing to gather sufficient information from multiple settings before concluding criteria are not met 6

Integration with Treatment Monitoring

  • Once diagnosis is established, the same rating scales can be used to monitor treatment response over time 1
  • The American Academy of Pediatrics recommends titrating medication doses to achieve maximum benefit with minimum adverse effects, using these scales to track progress 1
