1 Developing Evidence-based Interventions for Students with Autism and Asperger s Disorder Ruth Aspy, Ph.D., and Barry G. Grossman, Ph.D. The Ziggurat Group, PA Functional al Assessment ABCs Antecedent Consequences Presentation presented at the Texas Psychological Association November 17, 2007 FBA: Key Assumptions may be impacted by factors outside of immediate antecedents and consequences may result from biological factors Characteristics of ASD that Elicit Difficult s Impaired Theory of Mind/Mindblindness Weak Central Coherence Executive Dysfunction Sensory Differences Comorbid Disorders may result from skill deficits Foster-Johnson & Dunlap, 1993; O Neil, et al., 1997 Impaired Theory of Mind- Mindblindness Difficulty understanding the thoughts, feelings, and beliefs of others Difficulty predicting the actions of others Difficulty using words to describe one s own feelings Difficulty understanding non-literal language (e.g., sarcasm) Weak Central Coherence Tendency to focus on details and miss the big picture Difficulty understanding social situations 1

2 Problem Solving One way of viewing a problem Stuck thinking Sees facts instead of a whole Problems with cause and effect Does not see problems as having more than one option Problem solving is often literal Executive Dysfunction Difficulty with change Problems with regulating emotion Attention problems Disorganized Top 10 Situations that Trigger Insistence on Sameness 1. Annoying behavior 2. Activity interrupted 3. Losing a game 4. Object breaks 5. Event cancelled 6. Event delayed 7. Materials run out 8. Item misplaced 9. Sequence changed 10. Momentary separation Impact of Sensory Differences Distress in response to sensory stimuli Difficulty concentrating in noisy environments Cries Pain Sudden change in behavior Failure to attend to sensory stimuli (e.g., not responding to sounds) Low energy level Anxious and/or depressed Irritable Green, Sigafoos, Pituch, Itchon, O Reilly, & Lancioni (2006). Assessing al Flexibility in Individuals with Developmental Disabilities. Focus on Autism and Other Developmental Disabilities, 21(4) Emotional Reactivity Due to Sensory Differences Displays emotional outbursts when unsuccessful Is stubborn or uncooperative Often gets stuck in a situation Is overly sensitive Reacts overtly when sensory systems needs are not met Comorbid Psychiatric Disorders Comorbidity is to be expected (Gillberg & Billstedt, 200, p.237) ~65% comorbid psychiatric disorder (Ghaziuddin et al, 1998) 44% Phobia (Leyfer, et al., 2006) 37% Obsessive Compulsive Disorder (Leyfer, et al., 2006) 31% ADHD (Leyfer, et al., 2006) ~10% Major Depression (Leyfer, et al., 2006) Brenda Smith Myles 2
