Validation of the Korean Movement Culture Perception (KMCP) Scale Using the Rasch Model: Evidence from Korean and...

Area of Science:

• Psychometrics
• Cultural Studies
• Health Promotion

Background:

• The study focuses on validating the Korean Movement Culture Perception (KMCP) scale.
• This scale assesses participation in Korean Wave (Hallyu) elements like K-pop dance and Taekwondo.
• Hallyu is a significant cultural phenomenon characterized by participatory consumption.

Purpose of the Study:

• To validate the Korean Movement Culture Perception (KMCP) scale using the Rasch model.
• To assess the scale's construct validity and reliability among Korean and Chinese participants.
• To identify potential cross-cultural biases in the scale's items.

Main Methods:

• The Rasch model was employed for scale validation.
• A 21-item KMCP scale with a five-point Likert response format was used.
• Data were collected from 1,240 participants in Korea and China.

Main Results:

• The KMCP scale demonstrated high internal consistency (Cronbach's α = .954) and overall construct validity.
• All items exhibited adequate model fit, but item difficulty was concentrated, limiting perception range measurement.
• Differential item functioning (DIF) was identified in five items based on nationality, with three showing unfavorable cultural bias towards foreigners.

Conclusions:

• The KMCP scale is generally valid but requires revision of culturally biased items for cross-cultural equivalence.
• Improving the scale will enable more objective evaluation of Hallyu content.
• The study aims to support the global dissemination of Korean movement culture as a health promotion tool.
