Overview of Neurocognitive and Behavioral Assessments

1. Overview of Neurocognitive and Behavioral Assessments Sarah N. Mattson, Ph.D. San Diego State University

2. Outline of Presentation • Overview of assessments • General ability measures • Social and communication behavior • Behavior ratings • Findings from previous assessments

3. General Ability Measures • Bayley-III: Bayley Scales of Infant and Toddler Development-third edition • Ages: 1 to 42 months • Administration time: 45-60 minutes • DAS-II: Differential Abilities Scale-second edition • Ages: 2:6 to 17:11 years • Administration time: ~45 minutes • WAIS-IV: Wechsler Adult Intelligence Scale-fourth edition • Ages: 16:0 to 90:11 years • Administration time: ~60 minutes

4. Social and Communication Behavior • ADOS: Autism Diagnostic Observation Schedule • Description: a semi-structured assessment used to evaluate social and communication behavior across developmental levels and ages • Ages: toddlers to adults • Administration time: 30-45 minutes

5. Behavior Ratings • VABS-II: Vineland Adaptive Behavior Scale-second edition • Questionnaire and interview format • Assesses adaptive behavior (personal and social skills needed for daily living) • SCQ: Social Communication Questionnaire • Assesses communication skills and social functioning • CBCL: Child Behavior Checklist • Assesses adaptive and maladaptive behavioral functioning • DBD: Disruptive Behavior Disorder Rating Scale • Assesses disruptive behaviors like those seen in ADHD

6. Research Involvement • Location: San Diego State University • Direct assessment • ~2 hours to complete assessments • Parent assessment • ~1-2 hours to complete questionnaires • ~1 hour to complete interview at CBT • Compensation: ~ $20 financial incentive and feedback from testing

7. Previously Reported • Delayed development, including motor and speech • Mild to severe intellectual disabilities • Learning difficulties • Behavior Problems including compulsive behavior, short attention span, distractibility

8. Results from Ongoing Research • Parent and Child Questionnaire • Medical Issues • Developmental Milestones • School & Behavior • Behavior Ratings • Relation to Deletion Size

9. Medical Issues Data from 2006/2008, N = 29

10. Developmental Milestones Data from 2006/2008, N = 35

11. School & Behavior Data from 2006/2008, N = 29

12. Behavioral Functioning

13. Behavioral Functioning

14. Deletion Size & IQ r = -.83

15. Deletion Size & Adaptive Behavior r = -.58

16. Deletion Size & Behavior r = -.71

17. Summary So Far… • Behavioral assessments support previous reports and may be unique from other developmental conditions • Understanding the relation between deletion size and cognition and behavior will provide important information that will help families, especially those with new diagnoses

18. Plans for the Future • Further examine our existing data and continue to collect new information • Seek external funding for research activities

19. We couldn’t do this without you - THANK YOU!
