以结构性问卷对社区成年人进行郁证流行病学调查

目的：以结构性问卷对社区成年人进行郁证流行病学调查。方法：以整群抽样的形式对755名香港成年人采用横断面的方法进行结构性问卷调查。结果：以症状严重程度的自我评估为参考,受试者工作特征的分析结果显示,50分为郁证量表的最佳诊断分界点,其中,假阳性和假阴性值分别为25.8%和23.3%。郁证的患病率为6.2%,其中,女性患病率较男性高,男女之比为1：2.8（P=0.02）。郁证与年龄呈显著负相关关系（r=-0.22,P〈0.01）,但与婚姻状况、教育程度以及个人收入无显著相关关系。在郁证患者中,30.4%的患者表现出有极大的意愿去寻求治疗（男性为25.0%,女性为32.4%）。结论：郁证在成年人中颇为普遍,且患者有较高的寻求治疗的意愿。由此可见,此概念可以作为干预治疗的一个切入点,值得作更进一步的研究。本文分析了采用结构性问卷进行流行病学研究的局限性并提出了相应的改善措施

The use of a structured questionnaire to study stagnation syndrome in traditional Chinese medicine among adults living in community

Objective: Traditional Chinese medicine stagnation syndrome is a prevalent syndrome charac terized by mind-body obsession-like symptoms. To standardize the evaluation of this syndrome,previous studies have developed and validated a 3-factor, 16-item Stagnation Scale with good psychometric properties. The current study aimed to survey stagnation syndrome among adults in community.Methods: A cross-sectional questionnaire survey was conducted among 755 adults recruited by cluster sampling in Hong Kong.Results: Using self-appraisal of symptom severity as reference, receiver operating characteris tics (ROC) analysis suggested an optimized cut-off point of 50 on the Stagnation Scale, with false positive and negative rates at 25.8% and 23.3%, respectively. Prevalence of stagnation syndrome was revealed at 6.2%. It is more prevalent in women, with a male to female ratio of 1:2.8 (P=0.02). Stagnation showed significant negative correlation with age (r=-0.22,P＜0.01). It showed non-significant correlation with marital status and education level. Among people with stagnation syndrome, 30.4% showed substantial intention to seek treatment (male: 25.0%; female: 32.4%).Conclusion : Stagnation syndrome seems to be prevalent among adults and shows a fairly high rate of motivation for people to seek treatment. The construct can be a useful entry point for healthcare interventions and warrants further in-depth studies. Limitations of using a structured questionnaire for epidemiological studies and corresponding remedies are discussed.
