The construct validity was measure for exploratory factorial analysis, only questions with factor charge > or = 0.50 and that classified as a single factor has been retained and Cronbach's alpha coefficient was calculated.


RESULTS
residents (157) evaluated to 9 professors. The answer rate was of 75.1%. The questionnaire has 37 items. Five factors were identified with eigen values > or =1 which explained 52.5% of the total variance. The Cronbach's alpha coefficient was of 0.9596 for the questionnaire.
