Children with autism spectrum disorder (ASD) often exhibit difficulties with social communication skills that negatively impacts quality of life. Training parents to implement effective interventions that improve the social communication skills of children with ASD may facilitate parent-child interaction and ameliorate the impact of social communication impairment on children and their families. However, the unique cultural, societal, and historical contexts of Chinese parents may pose unique challenges when working to improve social communication outcomes for their child with ASD. The shortage of qualified professionals in China and other logistical barriers to traditional parent training implies telehealth may be a potentially effective and accessible way to teach Chinese parents to improve their child's social communication skills. This dissertation investigated the effects of a telehealth parent training package on fidelity to incidental teaching for four Chinese parents of children with ASD. Training included multi-media modules accessed via a popular social media platform in addition to asynchronous delayed video feedback to parents about their fidelity to incidental teaching procedures. Results indicated a functional relation between the telehealth parent training package and increased parent fidelity to incidental teaching. The telehealth parent training package also appeared to have a positive impact on child rate of mands, but this outcome varied across child participants. Increases in parent fidelity to incidental teaching coincided with an increase in each child's average rate of total mands, prompted mands, and independent mands. However, no apparent change was observed for spontaneous mands. Maintenance of parent fidelity was evident for all participants, though one participant's fidelity was slightly lower than mastery criteria at follow up. Social validity of the telehealth parent training was generally high across all participants both prior to and post intervention. Implications for further development and testing of the intervention package are discussed with a goal of promoting infrastructure for ASD treatment in China.
