FIGURE 2.

General Perceptions of people with MI among Tier I (A) and Tier II (B) teachers. Tier I teachers significantly reduced negative attitudes toward people with mental illness after the training (p = 0.0007, Cohen’s d = –1.09, two tailed t-test). Among the Tier II teachers, negative attitudes declined only as a trend after the training, but rose significantly at the time of the Refresher (p < 0.0001, η² = 0.15, one way ANOVA with Tukey’s multiple comparison post-test). Boxes represent 25th to 75th percentiles with an internal bar at the median. Whiskers delineate maximum and minimum data points. Tier I N = 22 retrospective pre, 23 post, Tier II N = 44 pre, 38 post, 56 Refresher. For the post tests, *, ***, **** represent p < 0.05, 0.001, 0.0001, respectively.
