Development and validation of a XXXX Juan () Questionnaire.

@entity4602 @entity1295 @entity158 @entity1353
OBJECTIVES: @entity4602 Juan (LJ, ) is a syndrome described in Chinese medicine (CM) that manifests with @entity1295 , fever, spontaneous sweating, indigestion, work-induced @entity158 , weakness of the limbs, and @entity1353 . The present study was conducted to examine the reliability and validity of a @entity4602 Juan Questionnaire (LJQ). METHODS: A total of 151 outpatients and 73 normal subjects were asked to complete the LJQ. Seventy-three normal subjects were additionally asked to complete the @entity1295 ( @entity1295 ). Twelve clinicians determined whether the 151 outpatients exhibited LJ or not. The internal consistency and construct validity for the LJQ were estimated using data from the outpatient subjects. The @entity1295 data were used to examine the concurrent validity of the LJQ. Total LJQ scores and the clinicians' diagnoses of the outpatients were used to perform receiver operating characteristics (ROC) curve analyses and to define an optimum cut-off score for the LJQ. RESULTS: The 19-item LJQ had satisfactory internal consistency (a=0.828) and concurrent validity, with significant correlations between the LJQ and the @entity1295 subscales. In the test of construct validity using principal component analysis, a total of six factors were extracted, and the overall variance explained by all factors was 59.5%. In ROC curve analyses, the sensitivity, specificity, and area under the curve were 76.0%, 59.2%, and 0.709, respectively. The optimum cut-off score was defined as six points. CONCLUSIONS: Our results suggest that the LJQ is a reliable and valid instrument for evaluating LJ.
