Applied behavior analysis (ABA) is an evidence-based intervention used to promote positive behaviors and decrease target behaviors. ABA is frequently used with children diagnosed with an autism spectrum disorder (ASD). In 2012, the state of Michigan passed a law providing insurance coverage for intensive ABA services for children up to 18 years of age diagnosed with an ASD. This new change has provided children with early on services that extend into young adulthood. Many children who do not receive an autism diagnosis may still benefit from ABA services, though insurance does not cover these services. This case presents a parent based consultation model to teach manding to an early elementary school student receiving special education services under a cognitive impairment eligibility and who has a diagnosis of attention-deficit hyperactivity disorder (ADHD). The parent trainer met with mom and dad weekly. The parent trainer modeled the intervention and data collection procedures for parents. Parents were asked to perform the intervention at least once a day, which consisted of ten discreet trials. The initial intervention provided an immediate verbal prompt and was later modified by fading out the prompt once mastery criteria was met. Each time the intervention was modified, the parent trainer modeled intervention and data collection procedures for parents. The goal was for the child to mand, with a visual prompt (i.e., food) and the verbal prompt “What do you want?” A mastery criterion was set at 80% of correct trials over 3 consecutive days. Baseline data showed that the child manded 0%. Once intervention started, correct manding occurred 10% on one day out of the week, and a total of 53 teaching trails were performed. After the first follow-up consultation meeting, manding was mastered with 80% of correct manding trials over 3 days in the second week. Additionally, teaching trials reduced to 4. The intervention was modified to delay the verbal prompt during teaching trials, and will later be modified to completely fade out the verbal prompt and visual prompt. Additionally, an intervention was added with a focus on generalization using the same immediate verbal prompting procedure that was in the initial mand intervention. The results provide support for the delivery of ABA through a weekly parent consultation model in the home setting.
