1. The criminal record mean was 8.0 (SD 2.12). The clean record group mean was 4.0 (SD 2.24). The no information group mean was 5.0 (SD 2.55). The overall test was statistically significant, F (2, 12) = 4.06, p =.045. The Tukey post hoc test results were significant for the criminal record group versus the clean record group ( F (1, 12) = 4.00, p = .044) and vice versa ( F (1, 12) = -4.00, p =.044). All other comparisons were not significant. Unlike the Tukey post hoc test, the Scheffe post hoc showed that the difference between the criminal record group and the clean record group, F (1, 12) = 4.00, p = .054, as well as all other comparisons were not significant. 2.
