尽管疑病症（HC）在《精神疾病诊断与统计手册》（第四版，文本修订版）中被认为是一种躯体形式障碍，但一些作者指出，HC的症状与某些焦虑症（即惊恐障碍（PD）和强迫症（OCD））重叠。很少有研究从实证角度解决这种重叠问题。在本研究中，我们使用判别函数分析来探讨主要诊断为 HC、OCD 或 PD 的患者在这些疾病的主要症状（即健康焦虑、强迫症和强迫症以及与恐慌相关的焦虑和回避）和关键认知偏差（即不能容忍不确定性、焦虑敏感性和身体警惕性）方面有何不同。 50 名寻求治疗的 PD 患者、21 名强迫症患者和 23 名 HC 患者在就诊期间完成了症状和认知的自我报告测量。结果表明，虽然患有 HC 的人会经历恐慌、强迫症和强迫症，但这些症状明显不如患有 PD 和 OCD 的人明显。相反，在认知偏差方面也发现了重叠，HC 患者表现出对不确定性、身体警惕性和对心血管症状的恐惧的不容忍程度升高。讨论了 HC 概念化和治疗的意义。
Although hypochondriasis (HC) is considered a somatoform disorder in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision), some authors have pointed out that the symptoms of HC overlap with certain anxiety disorders, namely, panic disorder (PD) and obsessive-compulsive disorder (OCD). Few studies have empirically addressed this overlap. In the present investigation, we used discriminant function analysis to explore how patients with a principal diagnosis of HC, OCD, or PD varied with respect to cardinal symptoms of these disorders (i.e., health anxiety, obsessions and compulsions, and panic-related anxiety and avoidance) and key cognitive biases (i.e., intolerance of uncertainty, anxiety sensitivity, and body vigilance). Fifty treatment-seeking individuals with PD, 21 with OCD, and 23 with HC completed self-report measures of symptoms and cognitions during their clinic visit. Results indicated that whereas individuals with HC experience panic attacks, obsessions, and compulsions, these symptoms are markedly less pronounced than among those with PD and OCD. Conversely, overlaps were found in terms of cognitive biases, with HC patients demonstrating elevated levels of intolerance of uncertainty, body vigilance, and fear of cardiovascular symptoms. Implications for the conceptualization and treatment of HC are discussed.
