Pivotal Response Treatment with and without robot-assistance for children with autism: a randomized controlled trial.

For the SRS rated by teachers, there were no differences between the groups on the percentages of clinical responders at endpoint and follow-up, although the difference at endpoint showed a marginal trend towards significance, with a higher percentage in the PRT + robot group compared with the other groups ( χ 2 (2) = 5.75, p = 0.050).
