Abstract
Achievement motivation is defined as the impulse that pushes people to the accomplishment of their goals through the realization of activities with mastery, responsibility and commitment. Numerous instruments have been made to measure achievement motivation in different populations. In the present study, a modified version of Monolini instrument was tested. It was applied on a sample of 198 students, with 68.5% women and 31.5% men, between 19 and 46 years old. The factor analysis with varimax rotation was forced to five factors, which explain the 57.7% of the total variance. The final instrument has 23 items with four response options and five factors: work and Compromise; mastery; competitiveness; hope for success, and fear of failure. The general internal consistency was 0.85. Concurrent validity was obtained with the Questionnaire of Academic Achievement Motivation.
