study equated for knowledge of nutrition. In other words, the degree to which both groups knew nutritional facts was roughly the same.
The next analysis conducted was a repeated measures (correlated) t-test conducted to determine whether the experimental group experienced gains in nutrition knowledge from pretest (Mean = 8.96) to posttest (Mean = 10.42). The findings that were observed for the performed t-test were significant (t = 4.28; df = 23; p<.01) indicating that program participants showed increases in the degree to which they knew certain basic nutritional facts as they related to diabetes.
In order to make sure that the observed gain in nutrition knowledge was not due to a testing effect (effect in which the pretest sensitizes subjects to the posttest causing an increase in scores), the control group's posttest nutrition knowledge scores were compared to the experimental group's posttest scores. The findings observed for this t-test comparison were significant (t = 2.67; df=46; p=.0111). Specifically, findings showed that, following exposure to the Diabetes Prevention Program, the experimental group (Mean = 10.42) had significantly more knowledge of nutrition as it related to diabetes than did the control group (Mean = 8.29). Thus, the finding could not have been due to testing.
Findings Observed For False Health Beliefs
The next series of conducted t-test analyses were performed to analyze false health beliefs data. Both the cell and marginal means observed for these data are presented in Table 4 with means
