50% reduction in the number of incidents in the first 21 days of treatment
Object Mouthing and Pica are common with individuals with autism spectrum disorder. Allison’s* parents struggled for years with their daughter’s constant urge to place anything in her mouth or rubbing it on her lips. It was impacting her learning and her social development. She had to be temporarily removed from school and her parents were unable to find care. Dad was able to work part-time from home, but struggled to find a care / work balance for his daughter and family.
Behavior Analysts conducted an analysis using an ABABCB reversal design. The case study began with repeated measures of behavior in a given setting that required an initial baseline phase, an intervention phase, a return to baseline, a reintroduction of the intervention phase, a second intervention phase, followed by a return to the preliminary intervention phase.
During the initial baseline Allison* engaged in pica and object mouthing 50 and 55 times per day. Following the introduction of the first procedure, the number of incidents decreased significantly to 13 instances recorded on the first day of the intervention. A return to baseline caused an increase of incidents but the number was still well below the number in the initial baseline phase.
After 21 days of treatment, the Pica and Object Mouthing have been reduced by 50%. Allison’s* parents are pleased and hopeful to reintegrate her back into school. We will provide updates in the months to come on further findings.
