In order to test the mediating role of perceived competence between each goal orientation (i.e. task and ego orientations) and intrinsic motivation in a motivational sequence in the context of university education, two models based on the cognitive evaluation theory and the achievement goal theory were tested with 276 Bolivian undergraduate students (138 males, 138 females), who completed Spanish versions of instruments designed to assess motivation, perceived competence, and positive emotions and interest. Two models were found with structural equation modeling techniques, one for ego orientation and one for task orientation. Results showed that perceived competence acts as a good mediator in the relation between ego orientation and intrinsic motivation, and as a partial mediator in the relation between task orientation and intrinsic motivation.
