Abstract：Objective:To develop a Dietary Care Prescription Needs Assessment Scale for chronic disease patients and test its reliability and validity,aiming to effectively assess dietary self-management care behaviors,identify patient needs,and guide targeted interventions.Methods:Guided by the Chinese Dietary Guidelines for Residents,the Balanced Diet Pagoda,and domestic/international chronic disease dietary guidelines,an initial scale was developed through literature review,qualitative interviews,and preliminary clinical surveys.From September to October 2023,209 chronic disease patients from five communities in Kunming,Yunnan province,were purposefully sampled to conduct item analysis,exploratory factor analysis,and reliability-validity testing.Results:The finalized scale comprised two dimensions(dietary self-care and dietary care needs),six secondary indicators,and 27 items.The Cronbach's α coefficient for the total scale was 0.844,with test-retest reliability of 0.850.Subdimension Cronbach's α values ranged from 0.629 to 0.882.The item-level content validity index(I-CVI)was 0.842～1.000,and the scale-level average content validity index(S-CVI/Ave)was 0.893,demonstrating strong discriminant and convergent validity.Factor analysis(KMO=0.887,χ²=2 535.669,ν=351,P<0.001)extracted six factors,accounting for 62.610%of cumulative variance.Model fit indices were excellent(χ²/ν=1.868,RMSEA=0.062,GFI=0.908,CFI=0.921).Conclusion:The developed scale exhibits strong reliability and validity,making it a suitable tool for assessing dietary care prescription needs in chronic disease patients.
