Significance indicates differences between “yes” and “no.” For example, the significant difference for OOAS total indicates that there was a difference in overall attitudes between those who have witnessed an overdose and those who have not on both the pre-test and the post-test.

In addition, significant differences between demographic groups are indicated by shaded cells.
