However, two factors (i.e., vigour and tirelessness) in AMES are conceptually redundant and overlapping. We aimed to revise the AMES to improve its brevity. In Study 1, a 5-factor AMES (i.e., vigour, motivation, confidence, concentration, and calmness) was tested and analysed. In Study 2, we tested the gender invariance of the 5-factor AMES and examined nomological validity. In Study 3, we examined the test-retest reliability of the 5-factor AMES. Across these phases, the results showed that the 5-factor, 10-item AMES had an adequate factor structure, construct validity, reliability, and gender invariance. Future studies may utilise the 5-factor, 10-item AMES to examine its influence on athletes’ psychological and physical responses in field or laboratory settings. We further recommend that sports psychologists adopt the 5-factor, 10-item AMES</em>.</p>}, number={1}, journal={International Sports Studies}, author={Shen, Wei-Jiun and Lu, Frank Jing-Horng and Zhang, Li-Wei and Kuan, Garry and Gill, Diane L. and Singnoy, Chatkamon}, year={2025}, month={Jun.}, pages={105–125} }
