Translating, modifying, and validating the Adult Picky Eating Questionnaire for use in China.

OBJECTIVE

The aim of this study was to translate, modify, and validate the Adult Picky Eating Questionnaire (APEQ) for use in China.

METHODS

Based on standard procedures, the APEQ was translated into Chinese. Four items were added in the final Chinese version of the APEQ (C-APEQ). For testing the psychometric properties of the C-APEQ, a total of 1069 participants (17-24 years; 52.57% women) were recruited from two universities in mainland China.

RESULTS

Exploratory factor analysis and confirmatory factor analysis supported the previous four-factor structure of the APEQ. Findings also showed that the C-APEQ had adequate internal consistency (α = 0.874) and test-retest reliability (ICC = 0.778). The C-APEQ demonstrated strong measurement invariance across gender. Furthermore, the C-APEQ composite score presented positive and significant correlations with eating disturbance, psychological distress, and psychological inflexibility. It also showed a negative and significant correlation with food-related life satisfaction.

CONCLUSION

Findings suggested that the Chinese version of the APEQ demonstrated sound psychometric properties. Thus, the C-APEQ can be a useful tool in future studies to accurately assess picky eating among adult population and explore the relationships between picky eating and other physical and psychological outcomes in a Chinese context.
