The project's results have significant potential impacts. They contribute to the advancement of evidence-based interventions for ASD by demonstrating the effectiveness of a digital parent trainer. We demonstrated that by deconstructing complex behaviors into simple and small building blocks, and by supplying video feedback, effective evidence-based therapies can reach many more children via their parents. This is a significant improvement over the situation today, where treatment relies on a too small pool of professionals. We proved that a digital platrofrm, by relying on students trained to give feedback and by breaking up complex interventions into simple steps, can open the bottleneck of the too small number of professionals and make effective therapy available to any child whose parent owns a smart phone.
The findings highlight the feasibility and scalability of delivering interventions through digital platforms, thereby increasing accessibility and reach. The project also emphasizes the importance of parental involvement and empowerment in ASD interventions, promoting a family-centered approach to therapy. Further uptake and success of the results require continued research, demonstration, and access to resources such as finance and supportive regulatory frameworks.
The primary outcomes of this study focused on key measures: communication events, joint attention and length of utterance. The average length of utterance in the test group, measured in whole words, increase by 0.74 and decreased (ie was shorter at the end of the trial) by 0.15 in the control group. The average number of responsive communication from the child in a ten minute period increased in the test group by 11.0 and decreased (was made lower) in the control group by 0.33 the average number of initiative communications of the child in a ten minute period increased in the test group by 27.0 and increased in the control group by 16.2 and the average number of joint attention events in a ten minute period increased in the test group by 9.8 and in the control group by 3.8.
