[The challenge of evaluating clinical competence].

The study is divided in two parts. The first one deals with theoretical aspects of evaluation. In the second part, the development of an instrument intended to explore clinical competence is presented. The importance of considering evaluation as part of a research process is emphasized in the first part. The diverse theoretical and action trends in the field of education are synthetized in two main tendencies: the active-participating and the passive-receptive. The influence of these two tendencies in the selection the objects for evaluation is also discussed. An evaluation instrument developed by us to explore clinical competence is placed within the active-participating tendency of education; the present state of this instrument is given in the second part. The instrument consists of multiple choice options of the true, false, don't know type. The instrument in its present version is the result of a long validation process. It explores particularly iatrogenic behaviors by omission or commission. The sample studied were 457 applicants for specialization courses in medicine. Of these, 127 were foreign applicants. The instrument was applied to the whole sample in one single session. The results showed a low general clinical competence, with similar results in mexican and foreign applicants. A clear difference was found in commission iatrogenia which was significantly more frequent than omission iatrogenia. The theoretical superiority of our test in relation the others is discussed.
