Traditional Chinese medicine stagnation ("yu") syndrome is characterized by a cluster of mind/body obstruction-like symptoms. Previous studies have operationalized the concept as a psychological construct through scale development, producing a three-factor 16-item inventory with good psychometric properties.
The study aimed to further validate the Stagnation Scale by confirmatory factor analysis (CFA) and examine self-appraisal of stagnation as an illness.
A cross-sectional questionnaire survey was conducted on a random community sample of 755 adults recruited by cluster sampling in Hong Kong.
CFA revealed a good fit of the three-factor model (CFI = .95; RMSEA = .077; SRMR = .043). ROC analysis suggested a cutoff score at 50 on stagnation total score for predicting self-appraisal of an illness condition, with false positive and negative rates at 25.8% and 23.3%, respectively. Overall, 6.2% participants self-appraised to suffer stagnation symptoms to a degree of an illness, and for it, 1.9% participants intended to seek treatment. Stagnation showed positive correlations with physical distress, depression, and anxiety (r = .59-.76, p < .01) and negative correlation with age (r = -.22, p < .01).
The Stagnation Scale appeared to be robust in factorial and construct validity. With prevalence of illness by self-appraisal at 6.2% and intention for treatment at 1.9%, stagnation is a fairly common condition associated with treatment-seeking behaviors.
中医“郁”症是以一组身心阻塞样症状为特征的。既往研究通过量表开发将其概念操作化为心理结构，产生了具有良好心理测量特性的三因素 16 项量表。
本研究旨在通过验证性因子分析（CFA）进一步验证郁量表，并考察自我评估的郁症作为一种疾病。
采用整群抽样法在香港随机抽取 755 名成年人进行横断面问卷调查。
CFA 显示三因素模型拟合良好（CFI=0.95；RMSEA=0.077；SRMR=0.043）。ROC 分析表明，郁总分 50 分可作为预测自我评估疾病状况的截断值，假阳性率和假阴性率分别为 25.8%和 23.3%。总体而言，6.2%的参与者自我评估有一定程度的郁症状，其中 1.9%的参与者打算寻求治疗。郁与身体不适、抑郁和焦虑呈正相关（r=0.59-0.76，p<0.01），与年龄呈负相关（r=-0.22，p<0.01）。
郁量表在因子和结构效度方面表现稳健。自我评估的疾病患病率为 6.2%，治疗意向率为 1.9%，郁是一种相当常见的与治疗寻求行为相关的疾病。
