The incidence of physical symptoms in depression was studied in 51 drug-free patients and in an age and sex-matched control group. Mean symptom intensity and number of symptoms were significantly higher in the patient than in the control group. The subjects' personality structure and relationships between their symptoms and degrees of depression and anxiety were examined using the Eysenck Personality Inventory (EPI), the Beck Depression Inventory, and the Spielberger State-Trait Anxiety Inventory, respectively. Of the variables studied, only the N score of the EPI was shown to influence the symptoms significantly. The effect of such non-specific factors as age, gender, use of alcohol, coffee, tea, and cigarettes was also evaluated and found to be minimal.
对51名未服用药物的抑郁症患者以及一个年龄和性别匹配的对照组进行了抑郁症身体症状发生率的研究。患者组的平均症状强度和症状数量显著高于对照组。分别使用艾森克人格问卷（EPI）、贝克抑郁量表和斯皮尔伯格状态-特质焦虑量表对受试者的人格结构以及他们症状与抑郁和焦虑程度之间的关系进行了检查。在所研究的变量中，只有EPI的N分数显示出对症状有显著影响。还评估了年龄、性别、酒精、咖啡、茶和香烟等非特异性因素的影响，发现其影响极小。
