Figure. Mean values and standard error bars for overall attitude, self-efficacy, satisfaction, and knowledge scores, from first-year medical students (n = 48) before (pretest) and after (posttest) the motivational interview training. a) Knowledge was scored based on the percentage of correct test answers out of a possible total of 11. b) Attitude, self-efficacy, and satisfaction were scored based on the average rating of each question on a 5-point scale (1 = strongly disagree, 5 = strongly agree). The dotted line represents the threshold of agreement, the point at which agreement statements start (4).
