Applied behavior analysis (ABA) is the gold standard treatment for autism spectrum disorder (ASD), and caregivers can learn to use ABA strategies to teach skills to their children with ASD. However, some families may not be able to access synchronous training due to cost, time, or location. Asynchronous modalities, such as DVDs or internet modules, remove some of these barriers. Other asynchronous options like podcasts need additional efficacy research. We evaluated a brief podcast about positive reinforcement with three caregivers and their children with ASD. We measured correct implementation of positive reinforcement and percentage correct on a multiple-choice quiz. The caregiver's implementation of positive reinforcement was assessed with a confederate and their child before and after listening to the podcast. If the caregiver's performance did not reach the mastery criterion, we provided modeling and coaching. Two of the caregivers implemented positive reinforcement at mastery after listening to the podcast. One caregiver needed modeling and coaching. All three responded correctly to more questions on the quiz after the podcast. These preliminary data suggest that a podcast may teach ABA strategies like positive reinforcement to caregivers of children with ASD, which could reduce some barriers to accessing training.
