Description
Summary:OBJECTIVES: We have developed a patient-reported syndrome scale: phlegm syndrome (PRS-PS) for efficacy assessment of Traditional Chinese Medicine (TCM). This study was conducted to evaluate the reliability and validity of the scale. METHODS: A cross-sectional survey was conducted for the 9-item PRS-ps. The patients with phlegm syndrome which is defined as a viscous, turbid pathological product causing a variety of diseases were recruited. After 24-48h, 30 patients were randomly selected to complete the PRS-PS again for retest reliability. For the patients with hyperlipidemia, triacylglyceride(TG) and total cholesterol (TC) were recorded to evaluate the criterion validity of the PRS-PS. The internal consistency and construct validity were analyzed according to Cronbach's coefficients, Spearman correlation and exploratory factor analysis. RESULTS: A sample of 115 patients (average age: 59, 47 males) completed the PRS-PS. The PRS-PS was easy to accept for patients, of which 96.6% completed the scale. The median completion time was 2min, which showed the convenience of the scale. There is no floor and ceiling effect on each item. The retest reliability of the scale was 0.896, of all items range 0.739 from 0.920. Cronbach's coefficient the scale was 0.643, and it declined after deleting any item. The Spearman correlation coefficients of these nine items and the global score were between 0.409-0.722. Exploratory factor analysis identified 3 primary dimensions that were consistent with the conceptual framework construction. TG was positively associated with the item of expectoration (p
