An interactive web-based course was studied with the aim to improve the behaviour of health care professionals when they interact with disabled patients. The course was offered to about 45.000 employees within the health care sector in a region of Sweden. According to a survey most respondents showed a positive attitude towards the course, but only four respondents had changed their behaviour towards disabled due to the course. A qualitative study was then made focussing on the reasons behind the fact that very few of the respondents changed their behaviour after the course, and what aspects did affect the total impact of the course. Aspects that influenced the total impact were engagement of management and co-ordinators, the relevance of the course contents for the work, the organisation of the studies, the aim and marketing of the course, time aspects, and the study form of the course.
