A common phenomenon among university students is procrastination, the dysfunctional postponing of tasks. Based on expectancy-value theory, the present study examined the relations between procrastination and some specific motivational characteristics of university students. A total of 881 German university students of teacher education and educational sciences completed a questionnaire. Results showed that procrastination while studying was negatively related to self-concept, study interest, mastery goal orientation and performance-approach goal orientation, while it was positively associated with work avoidance. Moreover, male students reported higher procrastination than female students. Study interest and work avoidance were the strongest predictors of procrastination. Thus, enhancing students’ positive motivational characteristics could reduce procrastination while studying.
