This research examines the relationship between 3x2 achievement goals, basic psychological needs, self-determined motivation, intention to be physically active, and satisfaction with life. The sample was comprised of 1706 Physical Education students with aged between 10 and 17 years old (M = 13.75; DT = 2.98). Descriptive analysis and linear regressions were performed. Validity and internal consistency were appropriate. The results pointed out the importance of competence and relationship satisfaction, self-determined motivation, and task[1]approach and other-approach goals in predicting the intention to be physically active, as well as task-based goals and satisfaction of the three basic psychological needs in predicting satisfaction with life. The 3x2 achievement goal framework is a relevant contribution in explaining the motivational and welfare consequences of the students.
