Note. df for t-tests of coefficients vary from 104 to 3612. Unstandardized coefficients are presented for the estimated post-test scores and the linear slope over time. For example, for communication skills, the intercept for the control group at Time = 0, controlling for pre-test communication skills, was 1.65 and it was significantly different from zero. In the same model, being assigned to PREP was associated with higher communication skills at post-test (.15; also significant). Further, pre-test scores were significantly associated with post-test scores on communication skills. Regarding linear slope (or change over time) on communication skills, the control group was estimated to have increased by .01 points each month following post. The PREP group increased significantly less per month (-.01) and higher pre-test scores on communication skills were also associated with less increase in communication skills over time.
