Gameful Experience questionnaire (GAMEX) in game-based learning in Iran: a psychometric study.

Area of Science:

• Educational Psychology
• Psychometrics
• Health Sciences Education

Background:

• Psychometric evaluation is crucial for ensuring the appropriate use of measurement instruments in research.
• The Gameful Experience Questionnaire (GAMEX) requires validation for specific cultural contexts.

Purpose of the Study:

• To assess the validity and reliability of the Persian version of the GAMEX in the Iranian context.
• To adapt and validate the GAMEX for use in educational research within Iran.

Main Methods:

• A forward-backward translation procedure was used for cultural adaptation.
• Content validity (CVR, CVI) and face validity (Impact Score) were assessed by experts.
• Exploratory Factor Analysis (EFA), Cronbach's alpha, and test-retest (ICC) were used to evaluate construct validity and reliability.

Main Results:

• All items demonstrated acceptable face and content validity.
• Exploratory factor analysis identified four dimensions: Enjoyment, Absorption, Creative Engagement/Autonomy, and Negative Emotional Arousal.
• The GAMEX showed high internal consistency (Cronbach's alpha = 0.91) and good reproducibility (ICC = 0.78).

Conclusions:

• The Persian version of the GAMEX is a valid and reliable instrument for measuring gameful experience in Iranian students.
• The questionnaire is recommended for future educational research assessing game-based learning environments in Iran.
