  1. Developmental Screens in the Office Setting Nathaniel Beers, MD, MPA

  2. OBJECTIVES • Why to do developmental screen • What types of screen tools are available • How effective are they • How are they administered • What types of additional services are available

  3. WHY SCREEN • 12-22% of children in US have developmental or behavioral disorders • Many options now exist to tailor screening to what works in specific practice setting • Services available to children with developmental delays from birth on • Better outcomes for participants: • higher graduation rates, delayed pregnancy, employment, decreased criminality • $30,000 to >$100,000 benefit to society

  4. Why Screen (continued) • Without screening: • 70% of children with developmental disabilities not identified (Palfrey et al. J PEDS. 1994;111:651-655) • 80% of children with mental health problems not identified (Lavigne et al. Pediatr. 1993;91:649=655) • With screening: • 70% to 80% of children with developmental disabilities correctly identified Squires et al, 1996, JDBP, 17:420 - 427 • 80% to 90% of children with mental health problems correctly identified Sturner, 1991, JDBP; 12: 51-64

  5. Types of Screening Tools • Two major categories • Developmental • Behavioral • Two mechanisms of administration • Parental • Provider

  6. Developmental Screening Tools • Provider • Denver • CAT/CLAMS • Bayley • Brigance • DIAL-R • Parent • Ages and Stages Questionnaire • Parent’s Evaluations of Developmental Status

  7. Denver Developmental Screening Test - 2 • Very commonly used screening tool • Birth to 6 years old • Poor sensitivity and specificity (40-60%) • 10-20 minutes to administer • Normed on diverse population sample • Multiple languages • Domains: fine and gross motor, language, and social skills

  8. DDST (continued) • Identifies children at 25,75, and 90% completion of task • Scored as concern if child completing task in shaded area (75-90%) • Scored as failure if not completed by time 90% complete • Referrals warranted for one failure or two concerns • Correct for prematurity till 2 years old chronological age

  9. CAT/CLAMSClinical Adaptive Test/ Clinical Linguistic and Auditory Milestone Scale • Similar to Denver but more focused on screening language and better at catching MR • Some parental report, some direct observation by provider • Very high specificity and sensitivity (>90%) • Not standardized in Spanish • Quick to administer due to age categories

  10. CAT/CLAMS (continued) • Start at chronological age or at last point • Credit given for completed tasks only • Basal age calculated at age where child completes all tasks at that age plus the value given to any additional tasks above that age • Basal age divided by chronological age then multiple by 100. This is the developmental quotient (DQ). • DQ<70 constitutes delays and should be referred for further evaluation

  11. Bayley Screener • Ages 3 to 24 months • Direct observation of skills by provider • Assesses three domains (more neuro focused) • 11-13 items at each age group (3-6 month breaks) • Specificity and sensitivity 75-86% • 10-15 minutes to administer • Not standardized in Spanish

  12. Bayley (continued) • Neurologic processes (reflexes, tone) • Neurodevelopmental skills (movement and symmetry) • Developmental accomplishments (language, object permanence, imitation) • Scored as low, medium and high risk for developmental disorders

  13. Brigance • Multiple age break downs • Infants and Toddlers • Early Preschool • Pre-K • K-1st • Assesses all domains • Direct observation by provider

  14. Brigance (continued) • Standardized in English and Spanish • Specificity and sensitivity 70-82% • Easy to administer • Children almost always experience success • Time to administer approximately 10 minutes, 20 minutes in a slow child • Realistically after practice 5 minutes

  15. Brigance (continued) • Simple scoring • Circle for correct, slash for incorrect • Stop after 3 in a row incorrect • Try to get 3 in a row correct as well • Look up score for age to determine if normal or delayed • Can show advanced skills

  16. DIALDevelopmental Indicators for Assessment of Learning • Screening tool to evaluate pre-school aged children • Effective for evaluation of school readiness • Speed version: 10 questions (motor, concepts, language domains) • Spanish and English • Good specificity and sensitivity • Scored at norms for age with breakdown at 1.0, 1.3, 1.5, 1.7, 2.0 SD below

  17. Ages and Stages Questionnaire (ASK) • Parent administered survey • Screens multiple domains (communication, gross and fine motor, problem solving and social) • Sensitivity 70-90% Specificity 76-91% • Validated in English, Spanish,Korean and French • Can be administered by provider or non-clinical person in cases of illiteracy • 5 minutes to administer when familiar, less if parents administer

  18. ASK (continued) • Pictures with some tasks to improve understanding of parents • Scored as 10,5 or 0 points for each question with norms in each domain for each age level

  19. Parents Evaluations of Developmental Status (PEDS) • Parent administered survey • Identifies when to screen, refer, counsel, or monitor • Sensitivity 74-79% Specificity 70-80% • Available in Spanish • 2 minutes to administer, less if parents do alone • ONLY 10 QUESTIONS • Easy flow sheet to prompt when to refer, counsel or re-evaluate

  20. Behavioral Screening • Parent or teacher • Connors • Child Behavioral Checklist • Pediatric Symptom Checklist • Vanderbilt

  21. Connor’s • Specific tool for ADHD with high sensitivity and specificity (>90%) • Breaks down into inattentive or hyperactive types • Not going to determine cause • Should never be used in isolation to make diagnosis • Must rule out additional underlying conditions (MR, LD, hearing and vision abnormalities)

  22. Connor’s (continued) • Spanish versions available • Teacher and parent forms • Good for monitoring response to medications • Scored by positives (2 or 3) on domains of inattention or hyperactivity

  23. Child Behavioral Checklist (CBCL) • Multiple domains • Can help identify other mental health conditions • Available in Spanish as well • Teacher and parent forms, child forms for older children • Not as valuable for following child once on treatment • Scored in multiple areas (i.e.:internalizing, externalizing, somatic complaints, aggressive behaviors, attention • Scored by points in each of the domains. Cut off for significance given for raw or T-scores

  24. Pediatric Symptom Checklist • Multiple domains of assessment • Single score or subscales (attention, internalizing and externalizing) • Not standardized in Spanish • Not helpful once a child has been referred • Parent or child fills out form • Scored as 0,1,or 2 • Significance if total score >24 in child 4-5 YO or >28 in child 6-16 YO • Attention: >7 points; Internalizing: >5; Externalizing: >7 points

  25. NICHQ Vanderbilt Assessment • Sensitivity and specificity of >94% if both parent and teacher ratings used • Detailed questions about behavior to assess attention, opposition, conduct, anxiety and depression • Performance questions as well • Scored by number of 2 or 3 in behavior assessment and 4 or 5 in performance assessment • Break down given for diagnosis of ADHD (inattentive, hyperactive, or combined), Oppositional Defiant disorder, Conduct Disorder, and Anxiety/Depression

  26. Additional Services • Specialists • Developmental Behavioral Pediatricians • Speech Pathologists, PTs and OTs • Other agencies doing evaluations • Early Intervention • Special Education

  27. Specialists • Huge backlogs to see specialists affiliated with Children’s (Nationwide issue) • Constraints on types of testing they can do by insurance companies • Medicaid does not allow Children’s to bill for psycho-educational evaluations • Need to assess if patient actually needs this service

  28. Other agencies • Some are great and some are not • Some are profit driven and have not invested in making sure the quality of evaluations is good • WATS has been very reliable in both quality and speed • No longer covered by HSCSN • Additional agencies in handout

  29. Early Intervention • Zero to three years old • Eligibility criteria vary by state and county • DC requires delay of 2 SD • Anyone can refer patient • MD, RN, parent, childcare provider • EI must complete evaluation and help parents transition to SPED when child is 3yo

  30. Special Education • 3 to 21 years old • Every child has right to evaluation • Anyone can request eval, but parent must consent • Eval must be conducted in child’s primary language and in English • DC requires eval started within 90 days of request (does not include summer or vacation) • Repeat eval every 3 years

  31. SPED (continued) • Individualized Education Plan (IEP) • Contains the services child will receive and goals for child • Updated annually • Parents do not need to sign at IEP meeting • Quarterly report on progress • Types of SPED • Inclusion, pull-out, or self-contained class or school
