It has become necessary to conduct a research on how effective the satisfaction of basic psychological needs in the development of psychological skills affecting the performance of the athlete during the competition can be achieved by going out of this theoretical way. In this context, it is aimed at investigating the effect of basic psychological needs on psychological skills of athletes. Method: A total of 150 athletes, 39 females and 111 males, participated in the research in various sports branches. “Assessment of Psychological Skills by Athletes Inventory” and “Basic Psychological Needs Inventory” have been conducted to athletes. Descriptive statistical analysis, t test, ANOVA and linear regression analysis have been used in the analysis of the data.

According to the results, the basic psychological needs explains 22.1% of the total variance related to the psychological skills of the athletes (β=.479, t=6.629, p=.000). Result: Accordingly, it can be said that satisfying basic psychological needs will contribute to the development of basic psychological skills.
