Pre and post-test knowledge information were collected through structured self-administered questionnaires. Data were analyzed using SPSS v20.A simple and multiple linear analysis models was used to test for significant association of variables at 95% CI, at p<0.05. The results were presented using tables and figures.
Results: The mean knowledge score at the pretest was 0.009±1.014 which improved to 0.365±0.901 on the posttest, with a statistically significant difference (t=6.965, p<0.01).
