The study explored the relationship between physical self-efficacy (PSE) and performance in physical activities. A sample of 43 participants, randomly selected from soccer clubs in Nigeria and the general population, was used. Results revealed that soccer players had an average score of 89.96 on the overall PSE scale, which was higher than the Nigerian national average of 83.16, as outlined in the test manual. The analysis found significant differences between soccer players and non-players on the PSE scale. Overall, the study highlighted that physical self-efficacy is a crucial psychological factor for success in soccer.
