摘要：background Stress resistance is very substantial and interesting for scientists,competitors,coaches,and psychologists.The main aim of the article was the psychometric examination of mental toughness in the sport questionnaire (MTSQ).participants and procedure The group of participants consisted of athletes presenting different levels of experience: Olympians,first-league,na_tional team: N = 421 athletes,including 190 women and 231 men,age M = 20.40,SD = 5.30.Test procedure: 124 state?ments were selected for exploratory factor analysis with the method of main components with rotation of intercor?relational orthogonal factors.It was used in order to check the factor structure of the tool and for the clear interpretation of isolated factors.As a result of the validation,42 statements were finally selected measuring three di?mensions of mental toughness.Each subscale consisted of 14 items.Next the reliability and the validity of the questionnaire were analysed.results The three-factor structure of the measured model of stress resistance accurately reflects the relation among stress re_sistances factors.Individual scales,at least mutually cor?related,present accurate and reliable operationalisation of dimensions of the stress resistance.conclusions The mental toughness in sport questionnaire (MTSQ) presents accurate and reliable operationalisation of stress re?sistance dimensions.
