The Effects of Group Size and Presentation Method on the Impact of a Drug Presentation.

摘要

The effects of group size (large vs small) and method of presentation (lecture, structured discussion, and unstructured discussion) on attitude change were assessed in a population of basic trainees, tested before and after a one-hour drug presentation. Neither group size nor method or presentation had a statistically significant effect upon attitude change. The artifact of statistical regression is dicussed as it relates to the assessment of attitude change in drug education and the problems encountered in separating regression effects from treatment effects.
