The self-efficacy and health educat

The self-efficacy and health education components of the intervention were scripted to promote fidelity of the intervention. Research staff members were trained to deliver the intervention in a consistent manner, and intervention fidelity was monitored periodically during the study. Monitoring included the accuracy of content, the affect of staff, and general atmosphere during laboratory training to verify that the self-efficacy enhancing intervention was implemented in a consistent manner and that elements of the self-efficacy enhancing intervention were not accidentally introduced into the other two groups. Monitors provided a plausible rationale for their presence so that the monitoring could be done without the staff’s knowledge.
