The present study examined whether female patients with an implantable cardioverter defibrillator (ICD) report more psychological distress than male patients, and whether somatosensory amplification mediates this relationship.
Consecutive ICD patients (N = 241; 33% women) participating in the Living with an Implanted Cardioverter-Defibrillator Study, completed a set of psychological questionnaires.
Symptom Checklist-90 and Somatosensory Amplification Scale.
Univariable linear regression analyses showed that female ICD patients reported more symptoms of anxiety (β = .13, p = .04), phobic anxiety (β = .13, p = .05), and somatic health complaints (β = .15, p = .02), and scored higher on somatosensory amplification (β = .24, p < .001) than men. Multivariable regression analyses, adjusted for demographic and clinical risk factors, revealed that somatosensory amplification was associated with more anxiety (β = .48, p < .001), phobic anxiety (β = .34, p < .001), and somatic health complaints (β = .49, p < .001). Sobel tests indicated that somatosensory amplification mediated the association between sex and these three domains of psychological distress (p = .0005, .002, and .0006, respectively).
Somatosensory amplification mediated the relationship between female sex and heightened anxiety, phobic anxiety, and somatic health complaints in ICD patients. Women may be more likely to misinterpret bodily sensations as indicative of deterioration in their condition. Interventions focusing on modifying these dysfunctional beliefs may reduce their psychological distress.
本研究旨在探讨植入式心脏复律除颤器（ICD）女性患者是否比男性患者报告更多的心理困扰，以及躯体感觉放大是否会介导这种关系。
连续参与植入式心脏复律除颤器研究的 ICD 患者（N=241；33%为女性）完成了一系列心理问卷。
症状清单-90 和躯体感觉放大量表。
单变量线性回归分析显示，女性 ICD 患者报告更多的焦虑症状（β=0.13，p=0.04）、恐怖性焦虑（β=0.13，p=0.05）和躯体健康投诉（β=0.15，p=0.02），躯体感觉放大得分也更高（β=0.24，p<0.001）。多变量回归分析，调整了人口统计学和临床风险因素，显示躯体感觉放大与更多的焦虑（β=0.48，p<0.001）、恐怖性焦虑（β=0.34，p<0.001）和躯体健康投诉（β=0.49，p<0.001）相关。Sobel 检验表明，躯体感觉放大介导了性别与这三个心理困扰领域之间的关联（p=0.0005、0.002 和 0.0006）。
躯体感觉放大介导了女性性别与 ICD 患者焦虑、恐怖性焦虑和躯体健康投诉增加之间的关系。女性可能更容易将身体感觉误解为其病情恶化的迹象。针对这些功能失调信念进行干预，可能会减轻她们的心理困扰。
