Our study aimed to investigate the influence of emotional intelligence (EQS; Uchiyama et al., 2001) on the psychological competitive ability (DIPCA.3; Tokunaga and Hashimoto, 2000) of female basketball players, with the view of improving their competitive performance.
In analysis I, we divided college basketball players into a high-performance group (HPG; 89 players) and a low-performance group (LPG; 203 players) on the basis of competitive results. By multiple-regression analysis with a stepwise method, we examined the influence of EQS 9 factors on each DIPCA 7 subscale; this indicated that the HPG score was significantly higher than the LPG score for the t-test. Results indicated that (1) Self-control and Situational Awareness positively influenced the HPG on multiple subscales in DIPCA; (2) Self-awareness was found to have a positive effect in the LPG on multiple subscales in DIPCA; and (3) Altruism in the HPG and Empathy in the LPG had negative effects, especially on Concentration.
In analysis II, we conducted the same analyses for top basketball players who belonged to a national team (NT; 16 players) or to company teams (CT; 61 players). We examined the influence of EQS 9 factors on each DIPCA 4 subscale, which indicated that the NT score was significantly higher than the CT score. These results indicated that (1) EQS factors positively influenced both the NT and the CT on DIPCA subscales; (2) a positive effect on DIPCA subscales was definitive in the NT and its strength tended to be the strongest among the four groups; and (3) Empathy and Altruism had a negative effect on the DIPCA subscales in the CT.
