PurposeLoss of appetite is caused by multifaceted disorders and affects an average of 40% of patients with heart failure (HF). The Council on Nutrition Appetite Questionnaire (CNAQ) and the Simplified Nutritional Appetite Questionnaire (SNAQ) are designed to assess appetite among older adults. We aimed to assess the psychometric properties of both CNAQ and SNAQ questionnaires in elderly Polish patients with HF.MethodsThe study sample involved 103 patients aged ≥ 65 years with HF diagnosed according to the New York Heart Association (NYHA) functional classes II-IV. The study was conducted among hospitalized patients with HF. In the study, the Mini Nutritional Assessment (MNA) questionnaire was used to assess the validity of the questionnaire. The evaluation of the following psychometric values was taken into account: data quality and homogeneity, factor structure, construct validity and internal consistency.ResultsParallel analysis confirmed the unidimensional structure of both CNAQ and SNAQ. The adjusted eigenvalues for CNAQ were 3.50 for the first factor and 0.62 for the second factor, and for SNAQ they were 2.2 and 0.31, respectively. For CNAQ, the desired CFA values were obtained after modification (RMSEA <0.06, CFI, TLI> 0.95), for SNAQ without modification (RMSEA <0.06, CFI, TLI> 0.95). The correlation between CNAQ and SNAQ and MNA was strong (rs = 0.8 and rs = 0.81, p <0.001, respectively). The internal consistency of the CNAQ and SNAQ tools was 0.88 and 0.86, respectively.ConclusionThe CNAQ and SNAQ questionnaires have positive psychometric properties and can be used to evaluate appetite among elderly Polish patients with HF.© 2019 Wleklik et al.
