疑病症（HC）是一种基于对良性身体扰动的误解而对患有严重疾病的恐惧。HC患者还会表现出检查和寻求安慰等行为，可能是为了减少与健康相关的恐惧。然而，缺乏对HC症状的实验行为分析。在本研究中，27名HC患者在两种情况下暴露于与个人相关的健康相关刺激中：(a)随后表现出寻求安全的行为（例如，检查）（n = 14）或(b)随后被指示不要进行此类行为（n = 13）。在两组中，都监测了主观焦虑和执行安全行为的冲动。结果表明，暴露于个人相关的健康触发因素会引起焦虑和执行安全行为的冲动。对于有这种行为的患者来说，这些感觉会减少。对于不这样做的患者，观察到焦虑和冲动的逐渐减少。研究结果在HC行为的概念和治疗方面进行了讨论，并与HC与恐慌和强迫症的可能关系有关。(c) 2006 Elsevier Ltd.版权所有。
Hypochondriasis (HC) involves preoccupation with fears of having a serious medical illness based on the misinterpretation of benign bodily perturbations. Individuals with HC also perform behaviors such as checking and reassurance-seeking presumably to reduce health-related fears. Experimental behavioral analyses of HC symptoms, however, are lacking. In the present study, 27 patients with HC were exposed to personally relevant health-related stimuli under one of two conditions: (a) subsequently performing safety-seeking behaviors (e.g., checking) (n = 14) or (b) subsequently being instructed not to perform such behaviors (n = 13). In both groups, subjective anxiety and urges to perform safety behaviors were monitored for I h. Results indicated that exposure to the personally relevant health trigger provoked anxiety and urges to perform safety behaviors. For patients who performed such behaviors, these feelings were reduced. For patients who did not, a more gradual reduction of anxiety and urges was observed. Findings are discussed in terms of the conceptualization and treatment of HC behavior, and are relevant to HC's possible relationship to panic and obsessive-compulsive disorder.
