摘要：The purpose of this study was to examine the effect of the dark triad traits on happiness and mental toughness among athletes of contact and non-contact sports, and non-athletes. 200 Taekwondo and Gymnastic athletes were selected by federation and 100 non-athletes conveniently, and completed the online questionnaires. Data was analyzed using Structural Equation Model. The results showed that narcissism had no effects on happiness of contact and non-contact sports athletes, and non-athletes; but Machiavellianism trait had significant and negative effect on happiness of non-contact sports athletes, and had no effect in athletes of contact sports and non-athletes. Besides, the happiness of three groups had significant and positive effect on three dimensions of mental toughness (Commitment, Control and Competitive Behavior). It is suggested that the sport psychologist and coaches have to pay attention to these athlete’s traits.
