Student's acceptability scores were measured with a Likert scale from 0 (total disagreement) to 10 (total agreement). Statistical analysis was performed using Mann Whitney U test. Results: P3 students agreed with most of BMTs. Pair comparisons between P1-P2 showed significant increase of means for Told treatment may involve pain and Sedative, besides significant decrease for Use of euphemisms.
