Self-confidence, Perception of Ability and Satisfaction of the basic Psychological Need of Competence in Training Stages

The main objective of this study was to identify differences in self-confidence, perception of ability and perceived need of competence between winner and loser teams of young volleyball players. The study sample was composed of 173 Under-16 (M: 14.63, SD: 1.05) participants (74 males, 99 females). The T-test for independent samples showed statistically significant differences in self-confidence (F 1,171 = 3.95; p=.048; np 2 =.023), incremental perception of ability (F 1,171 = 10.28; p=.002; np 2 =.890) and perceived competence (F 1,171 = 5.451; p 2 =.954) between players from winner and loser teams. Our results are supported by previous studies that showed highest values in winner teams than in loser teams.
