Data collection
After obtaining the necessary permissions, the corresponding author prepared a list of all eligible nurse educators, including their names, telephone numbers, and email addresses. Then, she contacted and gave them the necessary information about the study objectives. Participants who volunteered to participate in the study were assigned into the intervention and control groups using a table of random numbers. The first researcher created two WhatsApp groups for the control and intervention groups, and then electronically provided the written consent form and the pre-test questionnaire to both groups. She also explained them how to complete the questionnaire and shared a guide for answering questions in both WhatsApp groups. Some participants wanted to receive the questionnaire link via email. The post-test data was collected electronically one month after the training program.
