Abstract

Background: The present study was conducted to develop and validate the Persian version of the Volition in Exercise Questionnaire (VEQ).

Methods: The statistical population of the research was the students of Kashan University of Medical Sciences in 2022, selected using two-stage cluster random sampling. The reliability of the questionnaire was assessed using Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) and its validity was evaluated using face validity, content validity, and construct validity.

Results: Descriptive findings showed that 310 questionnaires were completed (mean age: 21.94 ± 3.03 years). The content validity of the questionnaire was confirmed by 5 experts. Exploratory and confirmatory factor analysis led to the extraction of five factors and the model had a good fit and the values and parameters of the model were statistically significant (χ²/df: 2.15, CFI: 0.915, TLI: 0.884 RMSEA: 0.07). The results showed that the overall Cronbach's alpha coefficient calculated for the tool and its factors were acceptable. Also, the stability of the questionnaire with a 2-week interval showed satisfactory results. The results of the research showed that the VEQ has a good validity and reliability to measure volition in exercise.

Conclusion: A review of the literature showed that there was no tool to measure the volition in exercise in Iran. The results confirmed the measurement model and showed that the obtained factors had a favorable fit as the original version.
