[Teaching nursing communication: a challenge].

The use of video has been described in the literature as favourable to changes in behaviours during communication. This study aimed at verifying the effect of a training programme in the use of categories of confirmation and discordance during the interaction (oral communication) between students and patients. The results evidenced the predominance of confirmation categories in interactions: there were no significant changes in the interaction profile before and after training. Authors concluded that the teaching of communication abilities has to be done during the undergraduate course and not only in one course or period.
