Development of the Sports Performance Inventory: A Psychological Measure of Athletic Potential

The current study extends existing sport psychology research by developing a more comprehensive athlete attitudinal survey—the Sports Performance Inventory (SPI). A multiple item survey consisting of sport-related attitudinal items was distributed to 274 students enrolled in a large Division I Midwestern university. A principal components analysis with varimax rotation performed on the original survey items resulted in an 83 item survey with six interpretable factors: Competitiveness, Team Orientation, Mental Toughness, Emotional Control, Positive Attitude, and Safety Consciousness. All subscales demonstrated adequate item discriminability and internal consistency. Important statistically significant differences between college/novice and male/female athletes were found: (1) College athletes were found to have a higher SPI composite than novice athletes; (2) College athletes were found to have a more positive attitude than novice athletes; (3) College athletes were more competitive than novice athletes; (4) Females were more team oriented than males; and (5) Novice males were more competitive than novice females, while college females were more competitive than college males. Implications of these findings and suggestions for future research are discussed.
