Preliminary Test of the Potential of Contact With Dogs to Elicit Spontaneous Imitation in Children and Adults With Severe Autism Spectrum Disorder.

IMPORTANCE: Finding strategies to enhance imitation skills in people with autism spectrum disorder (ASD) is of major clinical relevance. OBJECTIVE: To evaluate whether contact with dogs may be a useful approach to elicit spontaneous imitation in people with ASD. DESIGN: Participants completed a spontaneous imitation task under three experimental conditions: after a free-play interaction with a live dog, after a free-play interaction with a robotic dog, and after a waiting period that involved no stimuli. PARTICIPANTS: Ten children and 15 adults diagnosed with severe ASD. OUTCOMES AND MEASURES: Imitation ratio, imitation accuracy, and indicators of social motivation. RESULTS: Children appeared more motivated and engaged more frequently in spontaneous imitation in the live dog condition than in the other conditions. No differences between conditions were found for adults for imitation or social motivation. However, correlations suggested a possible trend for adults in time spent engaging with the live dog before testing and in increased imitation frequency. CONCLUSIONS AND RELEVANCE: The results are preliminary and do not indicate the utility of integrating (live) dogs into interventions aimed at promoting social motivation and enhancing imitation skills in people with ASD. However, they suggest that doing so holds promise. Larger scale studies are now needed. WHAT THIS ARTICLE ADDS: This research calls for occupational therapy practitioners' attention to the potential benefits that may derive from using dogs to promote spontaneous imitation, and increase imitation performance, in people with ASD, particularly children.

Can Dogs Assist Children with Severe Autism Spectrum Disorder in Complying with Challenging Demands? An Exploratory Experiment with a Live and a Robotic Dog.

OBJECTIVES: Prompted by the need to find effective ways to enhance compliance in children with autism spectrum disorder (ASD), and building on the increasing interest in dog-assisted interventions for this population, this study provides an exploratory test on whether dogs may assist children with severe ASD in complying with challenging demands while also decreasing behavioral and cardiovascular distress. DESIGN: A within-subject design was used. Depending on condition, participants were allowed to engage with a particular stimulus-their preferred toy, a live dog, or a robotic dog-before being exposed to a demanding task in which they had to wait for permission to eat a desired food item ("prohibition task"). Although inactive, the stimulus remained present during the prohibition task. SUBJECTS AND SETTINGS: Ten male children, aged between 6 and 9 years and diagnosed with severe ASD, participated in this study. All were clinically referred as having serious compliance difficulties in everyday routines. Testing occurred at participants' homes. OUTCOME MEASURES: Participants' emotional expressions, latency to distress, compliance levels, and behaviors that were shown during committed compliance were assessed during the prohibition task. In addition, cardiovascular reactivity to the task was monitored. RESULTS: Obtained data revealed significant differences between conditions for some of the considered measures. Latency to distress was higher in the live dog than in the toy condition. Committed compliance was higher in the live dog than in the toy and robot conditions. Quiet waiting during committed compliance was higher in the live dog condition than in the toy condition, and tension release behaviors were lower. In addition, heart rate reactivity was lower in the live dog condition than in the toy condition. CONCLUSIONS: The live dog condition appeared to have a calming effect on the participants, hypothetically facilitating compliance. Although promising, these findings are only preliminary and their clinical significance needs to be assessed in future studies.
