Abstract：Objective:To evaluate the clinical adaptability of the Sputum Pattern Efficacy Evaluation Scale developed in the early stage.Methods:Reliability analysis,linear regression analysis,factor analysis and other analysis methods were used to statistically analyze the data.The feasibility,reliability,validity and responsiveness of the scale were also evaluated.Results:In terms of scale feasibility,both the acceptance rate and completion rate were 100%,with a median time to complete the scale of approximately 3 minutes.The test-retest reliability,internal total reliability and reliability of each dimension of the scale were found to be acceptable,indicating that the scale is stable and that the dimension items are reasonably set.The content validity,structural validity and criterion validity of the scale were also acceptable,indicating that the content and structure of the scale are reasonable.All items could be effectively extracted;the variance of the four common factors reflected changes in the symptoms of tangible phlegm,invisible phlegm blocking the body's qi operation,invisible phlegm flow and agglomeration,and invisible phlegm overflowing all around the body,respectively.Regarding responsiveness of the scale,through the comparison of the items,dimensions and total scores of the scale between patients with sputum pattern and non-sputum pattern in different age groups,it was found that the scale could assist distinguish the symptom performance and degree of patients with sputum pattern and without sputum pattern at different ages from different levels.Conclusion:The scale demonstrates good feasibility,reliability,validity and responsiveness,which can effectively reflect the changes in the efficacy of sputum syndrome,and can be further popularized and applied in clinical practice.
