Abstract
The purpose of this research is to adapt the Mental Training Qestionnaire-SMTQ to Turkish, to show the results of the study of validity and reliability at the sport. For this purpose, a total of 306 athletes participated in the study voluntarily,166 of whom were male (Mage =22,37±2,95), and 140 were female (Mage=21,39±2,80) who were active in different sport branches. (football, basketball, handball, volleyball, tennis, badminton, athleticism, judo, taekwondo, boxing, wrestling). SMTQ consists of 20 items and 5 sub-dimensions (Mental Foundational Skills, Mental Performance Skills, Interpersonal Skills, Self Talk, Mental Imagery) and is evaluated as 5 Likert type. In the analysis of the data, Explaratory Factor Analysis and Confirmatory Factor Analysis were used for construct validity of the questionnaire, and Cronbach Alfa reliability analysis was used for internal consistency determination. The five factor structure determined by the exploratory factor analysis explains %69.219 of the SMTQ. In the confirmatory factor analysis results, the goodness of fit index values were determined as x2/sd (x2=303.69, sd=164)=1.85, GFI=0.91, CFI=0.95, NFI=0.91, AGFI=0.88, RMSEA=0.53, SRMR=0.48, RMR=0.34. It was determined that the internal consistency coefficients of the questionnaire changed between 0.82 and 0.91. As a result, it can be said that the Turkish version of “Mental Training Questionnaire-SMTQ” is a valid and reliable measurement tool for athletes.
