The aim of this study is to determine the effect of mental training levels of folk actors on their motivation for success and to compare them in terms of some variables. The study group of the research consisted of a total of 365 volunteer participants, 171 women and 194 men determined by the convenience sampling method among the players who participated in folk dance competitions in Turkey. "Mental Training Inventory in Sports" and "Sports Specific Achievement Motivation Scale" were used in the study. In the analysis of the data obtained, Cronbach Alpha reliability coefficient was calculated to examine the internal consistency of measurement tools. T-test and ANOVA tests were applied to evaluate the Mental Training Inventory in Sports and Sports Specific Achievement Motivation Scale levels according to the various demographic characteristics of the participants. In addition, the effect level between scales was evaluated by simple linear regression analysis. Whether the data met the prerequisites of parametric tests was determined by examining Skewness and Kurtosis (normal distribution of the data) values and Levene (variance equality) test results. As a result of the research, it was determined that there is a significant difference in the level of the players' motivation to show power according to their gender and the duration of their engagement with folk dances. In addition, mental training is effective on the motivation to show strength and the motivation to approach success. According to the results of this study, it is possible to increase the success and continuity of the athletes in this branch by supporting the folk dance athletes with mental training techniques and various studies to increase their success motivation. In addition, it can be suggested to investigate the factors that hinder mental training and negatively affect success motivation, to examine this case in terms of different variables and to conduct various studies on the branch of folk dances.
