This study was aimed to examine the effect of positive self-talk training on the competitive anxiety of anxious athletes. Methods: Participants were 52 team sports players (n=26 females and n=26 males), aged 18-23 years, randomly assigned into the experimental group (13 males and 13 females) and control group (13 males and 13 females). The experimental group received positive self-talk training for 30 days and the control was without any type of treatment. The dependent variables (competitive anxiety, general fear of failure) were assessed before and after the intervention. It was expected that positive self-talk reduces competitive anxiety, general fear of failure and increases self-confidence. Results: As expected, positive self-talk training decreased the level of competitive anxiety and general fear of failure and increased the self-confidence of the experimental group. Conclusion: the present study provides preliminary evidence that positive self-talk training for a period of 1 month can be used as an effective tool to reduce competitive anxiety and general fear of failure and enhance self-confidence.
