Reliability and validity of Chinese version of the Simplified Nutritional Appetite Questionnaire (SNAQ) in community-dwelling old people.

Objective: To investigate the reliability and validity of the Chinese version of simplified nutritional appetite questionnaire (SNAQ).
Methods: The SNAQ was translated and back-translated for the study population. We surveyed 122 community-dwelling residents aged ≥60 years in Beijing's residential communities. Participants underwent face-to-face surveys including the SNAQ, mini-nutritional assessment short-form (MNA-SF), FRAIL scale, Sarcopenia-Five (SCAR-F), 15-item Geriatric Depression Scale (GDS-15), 7-item Generalized Anxiety Disorder (GAD-7), 8-item Oral Frailty Index (OFI-8), 10-item Eating Assessment Tool (EAT-10), and Mini-Mental State Examination (MMSE). Cronbach's alpha was used to measure the internal consistency and the relationship between individual items. The construct validity was verified using the KMO-Bartlett. Concurrent validity was established to validate measures of the same constructs.
Results: Cronbach's alpha measured the internal consistency of the questionnaire at 0.694. The split-half reliability stood at 0.725. The construct validity of the SNAQ was confirmed using a KMO-Bartlett value of 0.648 (P <0.001). The MNA-SF, as validation benchmark, has a correlation coefficient of 0.345 (P =0.001).
Conclusion: The Chinese version of the SNAQ has good reliability and validity for older adults in community settings.
