ABSTRACT In sport and exercise promotion, it is important to consider goals because achieving these goals leads to a sense of well-being and behaviour adherence. Individuals often pursue multiple goals simultaneously. Therefore, it is also important to not only consider each individual’s combination of goals but also to identify so-called “goal profiles”. Taking a developmental-psychological perspective, the goal profiles of adolescents may differ from those of young adults. Furthermore, goal profiles might differ concerning the self-determined motivation, sport and exercise behaviour, and gender. Therefore, both age groups, 966 adolescents and 636 young adults, were questioned by self-report on their goals in sport and exercise, self-determined motivation, sport and exercise behaviour, and gender. A multiple-group-analysis for latent-profile-solutions was conducted resulting in six goal profiles for both age groups. As expected, the shape of these profiles differed qualitatively for the majority of adolescents and young adults: In adolescents, goals such as contact and the perception of challenge were more prominent, whereas in young adults, health, figure/appearance, and distraction/catharsis were dominant. Validation analyses support the profiles identified as they differ in self-determined motivation, sport and exercise behaviour, and gender. To more efficiently tailor interventions, an age-specific focus on goal profiles seems promising.
