Significant barriers to training have been introduced by the COVID-19 pandemic, limiting in-person professional activities resulting in the development of the novel remote training. We developed and evaluated a remote training approach for master trainers of the Caregiver Skills Training Program. Master trainers support community practitioners, who in turn deliver the Caregiver Skills Training program to caregivers of children with developmental delays or disabilities. The aim of this study was to evaluate the remote training of master trainers on Caregiver Skills Training Program. Twelve out of the 19 practitioners who enrolled in the training completed the study. The training consisted of a 5-day in-person session completed prior to the pandemic, followed by supporting participants' ability to identify Caregiver Skills Training Program strategies through supported coding of seven video recordings over 7 weekly meetings and group discussions and ended with participants independently coding a set of 10 videos for Caregiver Skills Training Program strategies. We found that master trainers' scoring reliability varied over 7 weeks of supported coding. All but one participant reached moderate or good independent scoring reliability despite a lack of ability to practice the Caregiver Skills Training Program strategies with children due to the pandemic. Taken together, our findings illustrate the feasibility and value of remote training approaches in implementing interventions.
