Abstract

Abstract:

Objective ·To translate St Andrew′s Nutrition Screening Instrument (SANSI), and test its reliability and validity. Methods ·With the consent of the authors, the SANSI was translated into Chinese in accordance with the "Brislin translation-back translation method" and the Chinese version underwent cross-cultural debugging. Five clinical medical staff were selected to a pre-survey on 10 patients, and the expression and structure of the scale items were fine-tuned according to the feedback. A total of 221 inpatients with mental disorders were selected by convenient sampling method in Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine as research objects from January to February 2022, and the general clinical data of these patients were collected. The correlation between the items in Part Ⅲ and the identified risks in that part was evaluated by Spearman correlation analysis, and some items were deleted according to the results. Eight experts in mental disorders or nutrition were selected to evaluate the items of Chinese version of SANSI, and then the content validation indexes (CVIs) were calculated. With the standard of Nutritional Risk Screening 2002 (NRS2002), Spearman correlation analysis was used to evaluate the calibration validity of Chinese version of SANSI. Cronbach′s α coefficient, split half reliability and inter-rater reliability (κ consistency coefficient) were used to evaluate the reliability of the Part Ⅲ of the scale. Results ·Through literal translation, back translation, cross-cultural debugging and pre-investigation, Chinese version of SANSI was formed. Among the 221 patients with mental disorders, 174 (78.73%) were males, the mean age was (64.12±13.87) years, and the duration of diseases was (26.06±17.65) years. There were 128 cases of schizophrenia (57.92%), 75 cases of organic mental disorders (33.94%), 10 cases of mood disorders (4.52%) and 8 cases of other mental disorders (3.62%). According to the results of correlation analysis in Part Ⅲ, the original items 1, 3, and 10 were deleted. The correlation coefficients between the remaining 7 items and the risk degree in this part were 0.391－0.734 (all P<0.01), which were retained. The item-level CVIs of Chinese version of SANSI ranged from 0.88 to 1.00, and the scale-level CVI was 0.95. The calibration validity of the scale with NRS2002 was 0.400 (P<0.01). The Cronbach′s α coefficient for Part Ⅲ was 0.759 and the split half reliability was 0.747. The κ consistency coefficient of 2 nurses using Chinese version of SANSI in the same group of 50 patients was 0.886 (P>0.05). Conclusion ·Chinese version of SANSI has good reliability and validity for hospitalized patients with mental disorders.
