摘要

Lao Juan (LJ

劳倦) 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.
