Delayed video-feedback and pyramidal training is a promising approach to teach incidental teaching to paraprofessionals in low-resource countries, but it may not be sufficient to increase child mands

Allocation: The researchers did not report any forms of randomization in this single-case experimental design study. Blinding: The authors did not provide specific information on whether the raters were aware of the experimental phase change in this study. The first author,who was the trainer of the study, was also one of the raters of implementation fidelity and treatment integrity. Study duration: The study lasted approximately 2 weeks and included three experimental phases. In phase one that lasted 1 month, the researcher in the US trained the bilingual coach in Japan to reach fidelity through four sessions. In phase two, the trainer taught the coach the training procedures within 1 h. In the last phase that lasted 2 weeks, the bilingual coach trained paraprofessionals in Japan to reach fidelity in incidental teaching strategies through an average of four sessions. The telehealth sessions were approximately 1 h long.
