Introduction: Considering the need to provide valid instruments for research and clinical work, the present study aimed to develop and evaluate the psychometric properties and factor structure of the Persian version of the monetary choice questionnaire.
Methods: In this cross-sectional survey, 400 students were selected through convenience sampling from all students of Kermanshah universities. The data were collected through Consideration of Future Consequences scale and Monetary Choice Questionnaire and were analyzed using statistical methods of Cronbach's alpha, intra-class and Pearson correlation tests, and the exploratory factor analysis.
Results: The findings showed that the internal consistency of the scale using Cronbach's alpha was 0.89, its split-half reliability was 0.88, and its test-retest reliability was 0.78 for a three week. The exploratory factor analysis results showed that the single-factor structure and the three-factor structure of the questionnaire were valid.
Conclusion According to findings, the monetary choice questionnaire has acceptable validity and reliability, and given the relatively short time it takes to be completed. So, it can be an appropriate tool for employing in both clinical and research situations.
