Abstract

A sample of 1273 mainland Chinese college students confirmed the four-factor structure of the Night Eating Questionnaire.

The simplified Chinese version of the Night Eating Questionnaire (SC-NEQ) was developed for use in mainland China.
A second-order model of the SC-NEQ also fit the data well.
The SC-NEQ demonstrated good reliability, with a Cronbach's alpha of 0.70 and omega of 0.83.
The total score of the SC-NEQ was moderately correlated with eating pathology (r = .35, p < .01).
Strong measurement invariance across gender groups was observed.

PURPOSE: The Night Eating Questionnaire (NEQ) is the most frequently used instrument for assessing night eating syndrome (NES), and it has been translated to many languages, including a traditional Chinese version in Taiwan. However, significant differences exist in the social, linguistic, and cultural contexts between mainland China and Taiwan. For its use in mainland China, a simplified Chinese version is needed and its psychometric properties should be further evaluated. Thus, the current study aimed to obtain a simplified Chinese NEQ (SC-NEQ) and validate its psychometric properties.

METHODS: According to standard procedures, the SC-NEQ was obtained by language transformation from the traditional Chinese version of NEQ. The SC-NEQ was then administered to 1273 mainland Chinese college students recruited from three provinces in mainland China.

RESULTS: The four-factor structure of the original English NEQ (morning anorexia, evening hyperphagia, mood/sleep, and nocturnal ingestions) was confirmed in the current sample. Moreover, a second-order model also fitted the data well. The SC-NEQ showed good reliability with a Cronbach's alpha and omega of 0.70 and 0.83, respectively. The total score of the SC-NEQ was significantly and moderately correlated with eating pathology (r = .35, p < .01). Strong measurement invariance across gender groups was also supported.

CONCLUSIONS: These findings suggest that the SC-NEQ can be a useful tool to assess NES in mainland China.

LEVEL OF EVIDENCE: V, descriptive (cross-sectional) study.
