We report the initial stages of validation of the 64-item Test of Performance Strategies, a self-report instrument designed to measure the psychological skills and strategies used by athletes in competition and during practice. Data were obtained from a sample of 472 athletes competing across a range of performance standards in a wide variety of sports. Exploratory factor analyses of their responses produced eight competition strategy subscales and eight practice strategy subscales, each consisting of four items. Internal consistencies of the subscales ranged from 0.66 to 0.81 (x = 0.75). Correlations among strategies were examined within and between performance contexts. Subgroups defined by age, sex and current standard of performance in sport differed significantly in their psychological skills and strategies.
