THE PSYCHOLOGICAL SKILLS INVENTORY FOR SPORTS - PSYCHOMETRIC CHARACTERISTICS AND APPLIED IMPLICATIONS

The Psychological Skills Inventory for Sports (PSIS R-5; Mahoney, Gabriel, & Perkins, 1987) contains 45 items designed to measure six psychological skills related to athletic performance. The present study examined selected psychometric properties of the PSIS R-5. Results of confirmatory factor analyses, conducted using intercollegiate athletes (N = 340), indicated that the predicted six-factor model did not fit the data. Model modifications were examined but failed to provide an adequate fit. Internal consistency estimates for five of the six scales also indicated poor reliability. The results are discussed in relation to the applied use of the PSIS R-5. Emphasis is placed on the need to carefully evaluate the psychometric characteristics of instruments that are designed for use in applied sport psychology.
