Abstract: Objective To translate the Health Promoting Behavior for Bloating scale (HPB-Bloat) for patients with functional abdominal distension, and to test its reliability and validity. Methods According to Brislin's translation model, the scale was translated, back-translated, culturally adjusted and pre-tested to form the Chinese version of the scale. Convenient sampling method was used to select 404 patients with functional abdominal distension in the Department of Spleen and Stomach Diseases of a tertiary grade-A hospital in Nanning from January to June 2022 to evaluate the health promoting behavior. SPSS 26.0 and Mplus 8.3 were used to complete the project analysis, reliability and validity and equivalence test of the scale. Results The translated HPB-Bloat for patients with functional abdominal distension consisted of 4 dimensions and 11 items. Item analysis showed that the scale items had good discrimination and homogeneity. Content validity index of the scale was 0.949, and the content validity index of each item ranged from 0.875 to 1.000. Exploratory factor analysis extracted 4 factors (diet, physical activity, stress management, health and treatment awareness), and cumulative variance contribution rate was 51.4%. Confirmatory factor analysis showed that the model fitting data was ideal. Criterion-related validity of the scale was 0.687; Cronbach α coefficient of the scale 0.796, and the test-retest reliability after 2 weeks 0.824. In cross-gender equivalence test, △CFI was≤0.010; and △RMSEA≤0.015. Conclusion The Chinese version of HPB-Bloat for patients with functional abdominal distension has good reliability and validity and cross-gender measurement equivalence, which can be used as an evaluation tool for the health promoting behavior of patients with functional abdominal distension in China.
