BACKGROUND
Functional somatic symptoms in depression disorder may cause inappropriate illness behavior hindering the treatment process. Health anxiety may play a role in this relationship, but few studies have examined it. The current study aimed to investigate the role of health anxiety in the relationship between functional somatic symptoms and illness behavior in patients with depression.
METHODS
The present study recruited 323 hospitalized patients with depression to complete the Patient Health Questionnaire-15, Whiteley-Index-7, and Scale for the Assessment of Illness Behavior, then constructed a structural equation model to examine whether health anxiety mediated the relationship between functional somatic symptoms and illness behavior.
RESULTS
The results showed significant correlations between any two of the three variables of interest. More importantly, health anxiety played a partially mediating role (42.86%) in the relationship between functional somatic symptoms and illness behavior. Further analysis suggested that elderly patients reached higher health anxiety than younger patients when their functional somatic symptoms were mild.
CONCLUSIONS
These results highlight that health anxiety may mediate the influence of functional somatic symptoms on illness behavior. The implications of assessing and intervening in health anxiety in patients with depression were discussed.
背景
抑郁症中的功能性躯体症状可能导致不适当的疾病行为，从而阻碍治疗过程。健康焦虑可能在这种关系中起作用，但很少有研究对此进行检验。本研究旨在探讨健康焦虑在抑郁症患者功能性躯体症状与疾病行为之间关系中的作用。
方法
本研究招募了 323 名住院抑郁症患者，让他们完成患者健康问卷-15、Whiteley 指数-7 和疾病行为评估量表，然后构建结构方程模型，以检验健康焦虑是否在功能性躯体症状和疾病行为之间的关系中起中介作用。
结果
结果显示，三个感兴趣变量中的任意两个之间存在显著相关性。更重要的是，健康焦虑在功能性躯体症状与疾病行为之间的关系中起部分中介作用（42.86%）。进一步的分析表明，当功能性躯体症状较轻时，老年患者的健康焦虑程度高于年轻患者。
结论
这些结果强调了健康焦虑可能在功能性躯体症状对疾病行为的影响中起中介作用。讨论了在抑郁症患者中评估和干预健康焦虑的意义。
