  • Note: A total of 53 intervention and 32 control group students participated, but respondents skipped some items. Changes in post-intervention survey for each variable were defined as follows: Less=baseline and post-intervention survey responses differed by −2 or less; No Change=baseline and post-intervention survey responses differed by −1, 0, or 1; and More=baseline and post-intervention survey responses differed by 2 or more. See Table 1 for definitions of Clinical Practice categories.
