Validation of "creactability" scale in football: a Rasch modeling approach

Area of Science:

• Sports Science
• Psychometrics
• Athletic Performance Measurement

Background:

• Assessing athlete attributes like quickness, creativity, and adaptability is crucial for performance.
• The
• creactability
• scale requires validation for its use in sports.
• Rasch modeling provides a robust framework for evaluating measurement properties.

Purpose of the Study:

• To evaluate the construct-related validity of the
• creactability
• scale in athletes using Rasch analysis.
• To confirm unidimensionality, assess Differential Item Functioning (DIF) based on team rank, evaluate item difficulty and ability ranges, and analyze subscale differences.

Main Methods:

• Rasch analysis was applied to data from 241 football players in the K-League.
• The
• creactability
• scale comprises 9 items across quickness, creativity, and adaptability, using a 7-point Likert scale.
• Statistical software (WINSTEPS, FACETS) was utilized for analysis.

Main Results:

• The study confirmed the unidimensionality of the 9-item scale with acceptable infit/outfit values (0.7-1.3).
• No statistically significant DIF was found across team rankings.
• The Person Separation Index (PSI) of 4 indicated good reliability for measuring
• creactability
• levels, with satisfactory fit across subscales and respondents.

Conclusions:

• The
• creactability
• scale demonstrates strong psychometric properties for measuring athlete attributes.
• The findings support the scale's validity and reliability for use in football and potentially other sports.
• The scale's ability to assess changes in quickness, creativity, and adaptability is confirmed.
