Classify Sensory Reactivity: Sensory Assessment for Neurodevelopmental Disorders
Many children with ASD and other neurodevelopmental disorders exhibit sensory reactivity differences. There are differences in the patterns of symptoms displayed, which require different treatment. The Sensory Assessment for Neurodevelopmental Disorders (SAND) combines caregiver interview and clinical observation and is feasible for use across the spectrum of individuals with NDDs, including those who are minimally verbal or have an intellectual disability, and those who are profoundly affected. The SAND provides objective quantification of sensory reactivity symptoms, to inform personalized treatment planning, and to measure change over time. SAND description, administration, interpretation of results, and case examples will be presented. As a result of attending this presentation, attendees will be able to: 1. Describe a classification system of sensory reactivity behavior preferences by predominant modality and behavior. 2. Administer, score, and interpret an assessment to classify sensory reactivity. 3. Integrate sensory reactivity assessment into treatment planning and provide specific recommendations

Psychometric analysis of Children's Stroop Color and Word Test Normative Update. Description of standardization sample and scores obtained, grouped by stratification variables, examined for fairness across groups. Models were constructed to identify important predictor variables. T-score tables were constructed to convert raw scores. The reliability of the test, including internal consistency and test-retest were analyzed. The test's validity was examined by analyzing the factor structure of the test and identifying convergent and discriminant validity with other measures.
