“…The exploratory factor analysis model of the NUFFE-CHI had six common factors, which was consistent with the number of common factors for the Swedish version. The items for factor 1 were almost the same as in the testing studies of the Swedish version (11) and the Hungarian version (14) , except that item 15, 'Health state', did not appear in factor 1 in our study. This might be because most of the participants in our study felt that they were healthy.…”

Objective: The present study aimed to translate the English version of the Nutritional Form For the Elderly into Simplified Chinese, as well as to test the reliability (homogeneity and stability) and validity (content and construct validity) of the Chinese version of the Nutritional Form For the Elderly (NUFFE-CHI). Design: The study adopted a cross-sectional design. The English version of the NUFFE was translated into Simplified Chinese and a questionnaire survey was conducted. The data were analysed with statistical methods to estimate the homogeneity, stability, content and construct validity. Setting: Jinzhou City, China. Subjects: A total number of 701 community-dwelling older adults answered the questionnaire, including background variables and the NUFFE-CHI. A small group of the participants (n 50) completed the NUFFE-CHI twice for test-retest reliability. Results: Cronbach's α was 0·65 and the split-half reliability was 0·67. Item-to-total correlation analyses showed that the scale has sufficient internal consistency. The test-retest reliability regarding the total scores of NUFFE-CHI was reflected in an intra-class correlation coefficient of 0·88. The intra-class correlation coefficients between the test and retest of the NUFFE-CHI items varied between 0·43 and 0·98. A content validity index of 0·83 explained good content validity. Construct validity was demonstrated in an exploratory factor analysis with a six-factor solution, explaining 57·65 % of the variance. Conclusions: This first testing of the NUFFE-CHI indicates sufficient evidence for reliability, content and construct validity. Further testing studies regarding homogeneity, concurrent validity, sensitivity and specificity are required before the NUFFE-CHI can be used as a screening instrument in clinical settings and in research. Keywords Instrument testing Nutrition Older people Screening instrumentThe prevalence of older people who are undernourished or at risk of undernutrition is high; for example, the prevalence rate was 27 % among geriatric in-and out-patients in a French study (1) and 22 % among older home-dwelling people in a Swedish study (2) . However, among older community-dwelling Chinese people, the prevalence rate was found to be 44 % (3) , and it was as high as 76 % among very old (90 + years) Chinese community-dwelling people (4) . In other Chinese studies performed among hospitalised patients, the prevalence has been found to vary between 20 % and 40 % (5,6) .To be undernourished or at risk of undernutrition among older people is an extensive problem, since it is associated with several serious factors including morbidity, longer hospital stays, mortality, deteriorated functional ability (7) , mobility impairment (8) , cognitive dysfunction (4,7,8) , reduced well-being (7) and poor self-rated health (2,4) . Moreover, older people who are widowed (3) , living alone (2,9) and of advanced age (3,4,8) are especially vulnerable for being at risk for undernutrition.In order to find potential and existing nutritional problem...

“…All of the item-to-total correlations were statistically significant, and are more than in earlier testing studies of the Swedish,18,19 Hungarian,33 and Norwegian versions of NUFFE 21,23. However, two of the correlation coefficients, for item 11 (fluid intake) and item 13 (eating assistance), were lower than the lowest recommended value of 0.20 for item-to-total correlations according to Streiner and Norman 27.…”

BackgroundNutritional screening instruments need to be evaluated in terms of reliability and validity and being able to demonstrate sensitivity and specificity for use in clinical practice and research. The aims of this study were to test the reliability and validity of the Norwegian version of the Nutritional Form For the Elderly (NUFFE-NO) in a sample of older home-dwelling people, and to use the short form of the Mini Nutritional Assessment (MNA-SF) as a standard.MethodsA postal questionnaire, including the two instruments, background variables, and health-related questions, was sent to 6033 home-dwelling older people (65+ years) in southern Norway. In total, 2106 persons responded and were included. Data were analyzed statistically regarding homogeneity, concurrent and construct validity, sensitivity, and specificity of NUFFE-NO.ResultsA Cronbach’s alpha coefficient of 0.71 and significant item-to-total correlations were obtained as measures of homogeneity. Concurrent validity was assessed by a correlation coefficient of −0.37 (P < 0.001) between NUFFE-NO and MNA-SF. NUFFE-NO could separate known nutritional at-risk groups as a measure of construct validity. A cut-off point of ≥4 for identification of older people at nutritional risk was found for NUFFE-NO with MNA-SF as a standard.ConclusionNUFFE-NO shows adequate psychometric properties regarding homogeneity and construct validity. MNA-SF was not found to be the most suitable standard to use, because a low correlation coefficient was obtained as a measure of concurrent validity and a lower cut-off point was found compared with another study using the Mini Nutritional Assessment (MNA®) as a standard for NUFFE-NO. The obtained cut-off point of ≥4 is not recommended for use in practice or research, because many false positive nutritional at-risk persons would then be identified. Further studies with suitable design have to be performed among older home-dwelling people using the MNA as a standard.
