    ABSTRACT: Lao Juan (LJ, ) is a syndrome described in Chinese medicine (CM) that manifests with fatigue, fever, spontaneous sweating, indigestion, work-induced pain, weakness of the limbs, and shortness of breath. The present study was conducted to examine the reliability and validity of a Lao Juan Questionnaire (LJQ). 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 Chalder Fatigue Scale (CFS). 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 CFS 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. The 19-item LJQ had satisfactory internal consistency (α=0.828) and concurrent validity, with significant correlations between the LJQ and the CFS 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. Our results suggest that the LJQ is a reliable and valid instrument for evaluating LJ.

    ABSTRACT: The present study was conducted to examine the reliability and validity of a Phlegm Pattern Questionnaire (PPQ) that was developed within the context of Traditional Chinese Medicine. A total of 292 normal subjects and 61 inpatients were asked to complete the PPQ. Among the 292 normal subjects, 73 college students were additionally asked to complete the Profile of Mood States (POMS) and the Chalder Fatigue Scale (CFS). Three (3) clinicians determined whether the 61 inpatients exhibited the Phlegm Pattern (PP). The authors estimated the internal consistency and construct validity for the PPQ using data from the normal and inpatient subjects. The POMS and CFS data were used to evaluate the concurrent validity of the PPQ. PPQ data and the clinicians' diagnoses of the inpatient subjects were used to estimate the sensitivity and specificity and to define the optimum cut-off point of the PPQ. The PPQ had satisfactory internal consistency (α=0.902 in normal subjects, α=0.919 in inpatient subjects) and concurrent validity, with significant correlations between the total score of the PPQ and all of the POMS and CFS subscales. In a test of construct validity using principal component analysis, a total of six factors were extracted, and the overall variance explained by all factors was 58.9%. In the test of discriminant validity using receiver operating characteristic curve analysis, the sensitivity, specificity, and area under the curve were 83.78%, 83.33%, and 0.860, respectively. The optimum cut-off level was defined as five points. These results suggest that the PPQ is a reliable and valid self-rating instrument for estimating the severity of PP.
