The present study tests the mediating role of hypochondriasis to explain the relation between anxiety sensitivity and panic symptomatology. Fifty-seven outpatients with clinically significant levels of panic symptomatology were selected to participate in the study. Measures of anxiety sensitivity, hypochondriasis, and panic symptomatology were obtained from standardized, self-administered questionnaires: the Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), the Whiteley Index of Hypochondriasis (WI; Pilowsky, 1967), and the Panic-Agoraphobic Spectrum Self-Report (PAS-SR; Cassano et al., 1997; Shear et al., 2001). Regression analyses were performed to test for the mediation models. The results show that the effect of anxiety sensitivity on panic symptomatology is not significant when controlling the hypochondriacal concerns, whereas the latter predicted panic symptoms. This result holds for the overall ASI as well as for the Physical Concerns and the Mental Incapacitation Concerns dimensions of the ASI scale. No evidence of a direct relation between the Social Concerns dimension and panic symptoms was found. The findings suggest that hypochondriacal concerns might represent the mechanism through which anxiety sensitivity is able to influence panic symptoms.
本研究检验了疑病症的中介作用，以解释焦虑敏感性与惊恐症状之间的关系。选取了57名有临床显著水平惊恐症状的门诊患者参与本研究。焦虑敏感性、疑病症和惊恐症状的测量数据来自标准化的自评问卷：焦虑敏感性指数（ASI；赖斯、彼得森、古尔斯基和麦克纳利，1986年）、怀特利疑病症指数（WI；皮洛斯基，1967年）以及惊恐-广场恐怖谱系自评量表（PAS-SR；卡萨诺等人，1997年；希尔等人，2001年）。进行回归分析以检验中介模型。结果显示，在控制疑病性担忧时，焦虑敏感性对惊恐症状的影响不显著，而疑病性担忧可预测惊恐症状。这一结果适用于整体ASI以及ASI量表的身体担忧和心理无能力担忧维度。未发现社会担忧维度与惊恐症状之间存在直接关系的证据。研究结果表明，疑病性担忧可能是焦虑敏感性影响惊恐症状的机制。
