The study aimed to identify the locus of control profiles in athletes and examine whether participants from distinct profiles significantly differed on anger and hardiness. The sample was made up of 383 athletes (Mage = 28.14; SD = 9.42) that completed a series of self-report questionnaires designed to measure: locus of control (E I-E), anger (STAXI-II) and hardiness (EPRM). Cluster analysis revealed two distinct profiles. Results of follow-up ANOVAs showed significant differences in temperament, reaction, internal anger expression, external anger expression, external anger control, commitment, challenge, control and hardy personality general factor. The low external locus of control profile reported the lowest anger levels and the highest hardiness levels. In conclusion, two locus of control external profiles emerged from the cluster analysis, in which the low external locus of control profile turned out to be the most functional profile.
