The aim of the present research was to evaluate a revised questionnaire about teachers' motivational styles. The instrument consists of eight short vignettes describing students problems at school. Following each vignette are four statements to be answered by an adult on a Likert Scale. Each statement represents a manner of the adult dealing with the problem, in a continuum, from highly controlling to highly autonomy supportive. 1296 elementary and secondary Brazilian teachers answered the questionnaires. The data were submitted to a confirmatory factor analysis based on a hypothetical model of four factors. The analysis indicated that two out of four indexes fitted well whereas two others came close to fitting the data. In this way, also considering other parameters, we may conclude that the present revised questionnaire is more capable to identify the continuum structure of the four motivational styles.
teachers motivational styles; control orientation versus autonomy; confirmatory factor analysis; intrinsic motivation
