Background: Wrong eating behaviors increase the risk of numerous chronic diseases.
Objectives: This study aims to determine the validity and reliability of the Mindful Eating
Questionnaire (MEQ) in the Iranian population.
Materials & Methods: In a validation study at the University of Guilan City, Iran, in 2019-2020.
First, the MEQ was translated based on the forward-backward method. After applying the changes
to the Persian version of MEQ (P-MEQ), 50 participants responded to the P-MEQ twice with an
interval of 3 weeks. Then, 384 Iranian students selected by the two-stage cluster sampling method
completed the P-MEQ to determine its construct validity. Sixty participants simultaneously filled
the P-MEQ and the Freiburg Mindfulness Inventory (FMI-SF) to determine concurrent validity. To
determine known-group validity, 23 very obese participants and a Body Mass Index (BMI) of over
35 kg/m2 were compared to individuals with a healthy weight (BMI: 18.5-24.9 kg/m2).
Results: The test-retest reliability of the P-MEQ was obtained as 0.59 for the total score, and it
ranged from 0.58 to 0.79 for the subscales. The first-order Confirmatory Factor Analysis (CFA)
results indicated that after removing four items with weak factor loading, the five-factor P-MEQ
model had appropriate goodness of fit (χ2/df=2.516, RMSEA=0.067, AGFI=0.835, IFI=0.924,
& CFI=0.916). The second-order CFA revealed that the latent components of awareness,
distraction, disinhibition, emotional response, and external cues reflected the concept of higher
levels of mindful eating acceptably (χ2/df=2.545, RMSEA=0.067, AGFI=0.825, IFI=0.912, &
CFI=0.905). However, there was a poor relationship between the total score of P-MEQ and
FMI-SF (r=0.24, P=0.07).
Conclusion: Regardless of concurrent validity, the Persian version of MEQ has proper construct
validity, test-retest reliability, and internal consistency.

• The test-retest reliability of the Persian Version Mindful Eating Questionnaire (P-MEQ) was acceptable to good.
• The deleting of 4 items (4, 8, 14, and 25) due to obtaining the weak factor loading could improve the values of fit
indices.
• Internal consistency and stability over time of the P-MEQ score were acceptable.
• The first and second-order five-factor structural model of P-MEQ has a good fit in the Iranian population.
