摘要

Objective

This study assesses the factor structure and psychometric properties of Farsi version of Night Eating Questionnaire.

Methods

In this cross-sectional study, we randomly selected 155 people referred to Shafa hospital and private psychiatry clinic in Rasht City, Iran. After translation to Farsi and back-translation to English, the face and content validity of NEQ Farsi version were evaluated using the opinions of a panel of experts and calculating the content validity ratio and content validity index. Then, the construct validity was evaluated by Confirmatory Factor Analysis (CFA), the Cronbach α coefficient was used for assessing internal consistency and the Intra class Correlation Coefficient (ICC) was used for assessing test-retest reliability.

Results

The mean age of participants was 41.1 ± 12.9 Years. The CFA results showed that the four-factor model had a good fit. Cronbach’s alpha showed an overall coefficient of 0.72. Spearman’s correlation coefficient was 0.97 and the intra-class correlation coefficient was 0.99 (95% CI 0.97–0.99), indicating a satisfactory level of test-retest reliability.

Conclusions

The Farsi version of the NEQ has acceptable psychometric properties for the Farsi language and Iranian culture, to be used as a valid and reliable tool in future research, care, and therapeutic activities.
