Mental toughness (MT) is an ability in controlling and responding to properly mind of moodes, concentration, commitment and attention in various situation. Originally, foreign countries have studied it continually and sequenaly for understanding of their appropriate structures explaining of athlete mental toughness and a success in a sport, especially in the professional or champion’s level of sport. For Thai athletes, an extending of this knowledgeable to deeply and specify is undoubtedly important and needs to be continued as well, such as a contact event of sport. The objectives were to examine the MT structural relationships on athlete success and analyze their norm scores for Thai contact sport athletes. The samples were screened for 917 from the whole sample of 2,030 Thai athletes who were participated in the National Games and were Thai athletes’ representative. There were youth males (65.0 %), and females (35.0 %) from other one previously study by the authors (Choosakul and Julavanichpong, 2014). They were chosen through random sampling. The sample size was specified by considering at the lowest test's criteria of structural relationships and invariance of mental toughness, 20 times more items than those in the inventory (Tabachnick & Fidell, 1996). The tools used in this study were MT Inventory (MTI) (Middleton, 2005a) and Athlete Success Inventory (ASI) (Choosakul and Julavanichpong, 2014), both had been proved as good content and construction validities and reliabilities. The data was analyzed by basic statistics including mean, standard deviation, and percentage for presenting any basic data. Structural equation modeling (SEM) technique was employed for the measurement of Thai contact sport athletes' MT and relation of the success in sport. Fit Indices were used X2 , CFI, TLI, RMSEA, path coefficient, df, dfdiff and X2 diff for appropriate and coherent data analysis of the model. Finally, T-score and percentile was used for inspecting Thai contact sport athletes norms of MT ability. The research ...
