In this study the specific foci were as follows: (1) to identify profiles of athletes in the junior-to-senior transition (JST) based on their personal characteristics (athletic identity, self-esteem and goal orientation) and (2) to describe the JST pathways relevant to the profiles. This quantitative longitudinal study included five measurements that were conducted approximately every six months. The following package of four instruments was used: the Athletic Identity Measurement Scale (Brewer, Van Raalte, & Linder, 1993), the Task and Ego Orientation in Sport Questionnaire (Duda, 1989), the self-esteem sub-scale from the Physical Self-Perception Profile – Revised (Lindwall, Hagger, & Asci, 2007) and the Transition Monitoring Survey (Stambulova, Franck, & Weibull, 2012). In the first measurement 100 club-based Swedish athletes (73 male and 27 female) with the mean age of 16.51 (SD = 1.32) participated. The Latent Profile Analysis identified three profiles of athletes and several similarities and differences can be seen in the profiles of athletes’ transition pathways. The main findings are: (1) three profiles of personal characteristics associated with different JST transition pathways were identified; (2) athletic identity appeared to be key personal characteristic that influenced the dynamic of adjustment and (3) different styles of coping strategies were associated with different JST pathways. The JST pathways relevant to the profiles are discussed based on the theoretical framework and previous research.
