Does Imagery Ability Matter for the Relationship Between Temperament and Self-Confidence in Team and Individual Sport Disciplines?

The main purpose of our study was to investigate the relationship among temperamental traits, a general tendency to use imagery, and self-confidence in sport. The specific aim was to verify if general imagery mediates the relationship between temperament and self-confidence in sport, but also with respect to individual and team sport disciplines. The study involved 144 athletes aged 19-25 years (75 men and 69 women) with different lengths of training (from 1 month to 18 years) and presented different sports levels: international ( = 12), national ( = 46), and recreational ( = 86). They also represented individual ( = 73) and team ( = 68) sports. The Imagination in Sport Questionnaire (ISQ), Trait Sports Confidence Inventory (TSCI-PL), and Temperament Questionnaire (EAS) were all completed by the participants. Results indicate that self-confidence is explained in about 13% by temperament and general imagery, but only general imagery ( = 0.22; < 0.05) and negative axes of the temperament-emotionality ( = -0.26; < 0.05). The test of the indirect effect of the negative axes of the temperament on self-confidence through general imagery, conducted by Preacher and Hayes bootstrapping procedure, revealed significant mediation [ = 0.37; 95% = (0.09; 0.68); = 0.46] suggesting that about 46% of variance explained in self-confidence by emotionality is related to general imagery. The other 3% of variance explained in self-confidence by the positive temperament axes is related to general imagery, however, it was insignificant. The general imagery explains the relationship between emotionality and self-confidence only in individual sports athletes.
