Questionnaire scaling: 1–5, 1 = acting according to the methods of motivational interviewing and 5 = acting according to ‘traditional advice giving’ (the doctor decides what is best for the patient). IC group = internal control group NOT receiving course in motivational interviewing. IM group = internal motivational group receiving course in motivational interviewing. EM group = external motivational group receiving course in motivational interviewing.
