Direct and Indirect Effects of a Web-Based Educational and Communication Skills Intervention “Promotoras de Donación” to Increase Donor Designation in Latinx Communities: Evaluation Study

An a priori power analysis, computed to detect a difference within subjects measured on 2 occasions, assuming α=.05 and a medium effect size (Cohen d=0.25) determined that a sample of 40 promotoras would yield a power of 0.91. All promotoras enrolled in the study completed the training and served as their own controls. There was no separate control group and thus no assignment to groups. This study had a single condition (ie, intervention) of which all participants and staff were aware.
