Qualitative outcomes and impact of a robotic intervention on children with autism spectrum disorder: A multiple embedded case study.

Most studies of social robot interventions for children with autism spectrum disorder have been laboratory experiments focusing on component skills. There is insufficient evidence documenting the qualitative impact of such programmes on social development and participation of children with autism spectrum disorder. This study aimed to identify the qualitative outcomes of a robot-mediated social skills training programme for children with autism spectrum disorder, examine the impact of such programmes on children's social participation and identify the essential elements of robotic interventions that are conducive to children's social development. A case study approach with a multiple case study design was adopted. Sixteen children with autism spectrum disorder, aged 5-11 years, were included. Participants received 12 weekly sessions of robot-mediated social skills training. The successful outcomes relating to social participation were identified as enhanced verbal expression, social awareness and emotional reciprocity. The impacts of the programme on personal development were identified as enhanced self-esteem, self-confidence and emotional expression. Robot friendship, the role of the robot as a facilitator and the presence of a human instructor capable of leading the programme were identified as essential elements of the positive changes. The encounter with a social robot was regarded as meaningful and important to the children with autism spectrum disorder.
