A revised 14-item Competitiveness Index was developed to better measure the desire to win. This new scale shows strong reliability and validity, correlating well with existing measures of competitiveness and achievement.

Area of Science:

  • Psychology
  • Social Psychology

Background:

  • The Competitiveness Index (CI) is a 20-item true-false measure assessing the desire to win.
  • A need for a more psychometrically sound scale was identified.

Purpose of the Study:

  • To develop and validate a modified, more reliable version of the Competitiveness Index.
  • To assess the psychometric properties of the revised scale.

Main Methods:

  • 213 undergraduates completed the original CI and a modified 5-point Likert-type scale version.
  • Principal component analysis and reliability analyses were conducted.
  • Items were removed to refine the scale structure.

Main Results:

  • An initial four-factor solution was identified, later refined to a two-factor solution (Enjoyment of Competition, Contentiousness).

  • The final 14-item Revised Competitiveness Index demonstrated high internal consistency.
  • The revised scale positively correlated with the original CI and other established measures of competitiveness and need for achievement.

    • Conclusions:

    • The 14-item Revised Competitiveness Index is a psychometrically sound measure.
    • The Enjoyment of Competition and Contentiousness factors provide a robust assessment of competitive desire.
