Study hypothesis

This project has two specific aims:
a. To assess the impact of different intended durations of delivering a curricula (all at once, or 'bolus' delivery versus small amounts delivered over a longer period of time, or 'drip' delivery) on cliniciansÂ’ knowledge, confidence and communication practices about herbs and dietary supplements
b. To assess the impact of mode of delivery by providing the individual modules as an email ('push' method) versus as an email inviting the participant to access an Internet site to get the modules ('pull' method)

Participant exclusion criteria

Potential participants will be excluded if they:
1. Do not have an email address or regular access to the Internet
2. Do not plan to retain their email address for at least 4 months
3. Do not check their e-mail at least twice weekly
4. Indicate at enrollment that they are unwilling to complete the baseline and follow-up assessments
5. Have enrolled in this curriculum previously (e.g. participated in the pilot study)
6. Live or work outside the US, because the laws governing herbs and dietary supplements are variable outside the US, and product availability also differs outside the US

We will not include laypersons who are simply interested in learning about herbs and other dietary supplements. We will ask all participants for their professional license number and the state in which they are licensed to verify professional status.
