[A controlled study of the short-term and long-term effects of a "train the trainers" course--secondary publication].

Unlabelled: This is an intervention-study discussing the long-term effects of a 3-day "Train the trainers course" (TTC). In the intervention (I) group 98.4% of doctors participated in a TTC, both specialists and trainees. Knowledge about teaching skills increased in the I group by 25% after the TTC; a result which was sustained at six months. Teaching behaviour was significantly changed as the use of feedback and supervision had increased from a score of 4 to 6 (max. score = 9).

Conclusion: A 3-day residential TTC has a significant impact on knowledge gain concerning teaching skills, teaching behaviour and clinical learning culture after six months.
