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

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

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
