Objective:To construct the patient reported outcome (PRO) scale for Qi stagnation and blood stasis syndrome (QSBSS). Method:According to the international principle of scale construction and traditional Chinese medicine theory
the theoretic framework of this scale was build.Through analyzing 102 references pertaining to the QSBSS
retrospectively reviewing 209 cases and discussion of 14 experts
the item pool of this scale was formed.The primary PRO scale was shaped by survey and interview of participants with a small sample size.The eventual PRO scale was constructed after the survey of 338 QSBSS participants by the 7 analysis methods
partly including item distribution
tendency of dispersion
factor analysis
and was revised in the light of experts suggestion.The PRO scale was also evaluated by clinical study of 213 QSBSS participants and 100 non-QSBSS participants from the perspective of feasibility
reliability
validity and discrimination degree. Result:Evaluation scale for QSBSS based on PROs was eventually build with 37 items
mainly including 22 physiology items
9 psychology items
1 independent item and 5 community items.The reliability analysis showed that the Cronbach α coefficient was 0.716
half reliability was 0.666.Validity analysis showed that 64.70% of the variables could be interpreted by the common factor
and the Spearman coefficient of association was larger than 0.2 except the independent item
and P value was smaller than 0.01 in terms of t test for the whole scale and separate fields of the scale. Conclusion:Evaluation scale for QSBSS based on PROs embraces high level of reliability
validity and discrimination degree
which can be used for the evaluation for the efficacy and effectiveness of QSBSS patients.
