健康焦虑的研究现状

健康焦虑是一种由轻到重的连续性的症状谱,它的极端形式被称之为疑病症.关于健康焦虑的流行病学数据很少,发病的机制和原因也不清楚,但大多数的研究证实健康焦虑与焦虑障碍有相同的认知过程.疑病症的临床表现为疾病观念、躯体症状、歪曲信念和行为,健康焦虑只是在程度上轻于疑病症,并没有发生质的改变.在健康焦虑的治疗中最受关注的应属正念认知疗法,它在很多方面都优于传统的认知行为疗法,当然其他治疗方法也能起到一定的辅助作用.健康焦虑带来的危害是巨大的,因此社会将面临重大挑战.     

焦虑对重量感知判断的影响

行动经济理论认为个体对物理环境的感知与其具备的资源有关,而焦虑与资源不足有关。基于此,本研究通过3个实验来探讨3种不同性质的焦虑对重量感知判断的影响。实验1通过身体姿势诱发焦虑,结果发现同放松的身体姿势相比,焦虑的身体姿势能诱发出焦虑且此姿势下个体会认为背包的重量更重。实验2通过具有压力性的外部任务诱发焦虑,结果显示同奇偶判断任务相比,心算任务能诱发出明显的焦虑且此任务下个体将背包的重量判断为更重。实验3探讨特质焦虑的影响,结果发现高特质焦虑个体同低特质焦虑者相比会认为背包的重量更重。本研究表明焦虑会影响个体对物体物理属性的感知。     

广泛性焦虑个体的注意偏向

探讨广泛性焦虑个体在一般情境和不确定性情境下注意偏向的特点。采用点探测注意搜索任务研究了在一般情境下和不确定性情境下广泛性焦虑个体的注意偏向, 结果表明高广泛性焦虑个体的注意偏向以对威胁性刺激的注意转移困难为主, 不确定性情境会让广泛性焦虑个体更容易处于紧张焦虑的状态当中, 从而对情绪性刺激尤其是消极刺激表现出更多的注意偏向和对情绪性刺激直接的注意敏感性。     

焦虑情绪对决策的影响

焦虑情绪会对人类的决策行为及其结果产生深刻的影响,其中最突出的表现是,焦虑水平的提高会使决策者倾向于回避风险,做出保守的选择。近年来,国外研究者从不同的角度分析这一现象的原因,归纳出了几种可能的影响因素——包括认知资源因素、信息加工因素、概率偏向因素与情绪取向因素等。这些因素的提出,促进了对焦虑影响决策的机制的认识。它们间虽有密切联系,但有待于整合成为一个统一的体系     

新型冠状病毒肺炎疫情下普通民众焦虑的影响因素研究

为考察新型冠状病毒肺炎疫情下普通民众焦虑情绪的影响因素,采用自陈式问卷,对新型冠状病毒肺炎疫情防控下的1050位普通民众的疫情经历、媒体信息暴露时长及性质、疫情风险感知和焦虑进行调查。结果发现新型冠状病毒肺炎疫情防控当下民众焦虑情绪的发生率为18.0%,焦虑情绪的发生率在性别、年龄、受教育程度、婚姻状况和月收入等方面没有显著的差异;疫情经历、媒体信息暴露时长、负面信息暴露和感知疫情的严重性会增加焦虑情绪产生的可能性,正面信息暴露、对疫情熟悉度和可控度的感知可以减少焦虑情绪产生的可能性。这些结果说明了疫情经历、媒体信息暴露时长和性质、疫情风险感知是疫情防控当下民众焦虑出现的重要因素。     

负面评价恐惧对社交焦虑的影响:基于社交焦虑的认知行为模型

在社交焦虑认知行为模型的理论视角下,本研究拟探讨负面评价恐惧、不确定性容忍度和依赖型自我构念对社交焦虑的影响及其作用机制。以424名大学生为被试,使用问卷调查法的研究结果表明:(1)负面评价恐惧对社交焦虑有显著预测作用,且不确定性容忍度在这一关系中的中介作用显著;(2)不确定性容忍度的间接效应受到依赖型自我构念的调节。具体而言,该中介效应在高依赖型自我构念群体中更为显著。本研究结果不仅有助于揭示负面评价恐惧对社交焦虑的影响及其作用机制,而且对社交焦虑的预防和干预也有一定的理论和实践指导价值。     

社会焦虑的概念辨析与根源探究

人格特质对考试焦虑的影响:多重中介效应分析

目的:探讨自尊、惧怕负面评价及无法忍受不确定性在人格特质和考试焦虑间的中介作用。方法:采用人格问卷简式量表EPQ-RSC、Rosenberg自尊问卷、惧怕负面评价量表简表、无法忍受不确定性量表和考试焦虑量表测量410名在校高中生和大学生。结果:(1)相关分析表明,神经质、惧怕负面评价、无法忍受不确定性及考试焦虑之间彼此正相关显著;外向性与自尊正相关显著,与惧怕负面评价、无法忍受不确定性及考试焦虑等负相关显著;精神质与自尊、惧怕负面评价及考试焦虑等负相关显著;自尊与神经质、惧怕负面评价、无法忍受不确定性及考试焦虑负相关显著。(2)回归分析表明,人格特质中的神经质和精神质能显著预测考试焦虑,无法忍受不确定性在人格特质和考试焦虑之间起部分中介作用;结构方程模型分析结果显示,人格特质中神经质和精神质对考试焦虑的直接效应显著,经由自尊、惧怕负面评价和无法忍受不确定性对考试焦虑的间接效应也极为显著。结论:自尊、惧怕负面评价和无法忍受不确定性在人格特质与考试焦虑间起着中介作用。     

健康受试者风险感知情况及影响因素——基于NVivo11的质性文本分析

采用NVivo11软件对健康受试者的风险感知情况和影响因素进行分析。认为健康受试者整体对Ⅰ期药物临床试验风险呈弱感知特点。感知有风险的受试者有些对知情同意认知不充分,有些重复受试者由于多次参加试验导致风险脱敏;感知无风险的受试者抱有不知者无畏、自我风险规避和信任托付心态来参加;相反,研究者对待知情同意过程和试验风险更加科学和理性,充分尊重受试者的自主选择权并期待与受试者良好合作。由此可见,对风险的错误感知警示健康受试者不可盲目参加试验,提高风险认知能力,做好风险预判,有助于保障自身安全和试验的顺利开展。

How Do Elements of a Reduced Capacity to Withstand Uncertainty Relate to the Severity of Health Anxiety?

Intolerance of uncertainty (IU)—a multidimensional cognitive vulnerability factor—is associated with a variety of anxiety disorders and health anxiety (HA). To date, few studies have assessed whether IU dimensions (prospective and inhibitory IU) are differentially associated with HA and whether their contributions are independent of anxiety sensitivity (AS). This study addressed these issues using independent community (n = 155; 81% women) and undergraduate (n = 560; 86% women) samples. Results indicated that prospective IU, but not inhibitory IU, had significant positive associations with HA in community dwellers and undergraduate students. AS somatic and cognitive concerns were also significant predictors among both samples. In addition, severity of IU dimensions among individuals reporting elevated HA were compared against individuals diagnosed with generalized anxiety disorder, social anxiety disorder, panic disorder, and obsessive–compulsive disorder. Results indicated minimal differences between those with elevated HA and each of the anxiety disorder diagnoses. Findings lend support to the unique transdiagnostic nature of IU and support commonalities between HA and anxiety disorders.     

Toward a new conceptualization and operationalization of risk perception within the genetic counseling domain

The purpose of this paper is twofold. First, it provides an historical overview of studies of risk, risk perception, and decision making under risk within the genetic counseling domain. Second, it proposes an alternative conceptualization and operationalization for the study of risk perception. The conceptualization involves probability, adversity, incompleteness, and ambiguity. Prior studies of risk perception focus on the recurrence risk and operationalize risk perception by asking for interpretations of the magnitude of the probability of the outcome. Their focus is on the probability of a particular outcome. We formulate the problem in terms of a gamble and suggest that risk perception be operationalized in terms of the riskiness of the gamble. Our focus is on the riskiness of a decision option which entails two or more outcomes.     

The interaction model of anxiety: An empirical test in a parachute training situation

The interaction model of anxiety was examined by assessing both state and trait anxiety in 64 male military personnel on a Basic Parachutist Course. Two separate tests of the interactional model of anxiety were conducted, involving physical danger and social evaluation situations. The same subjects participated in both studies. In both physical danger and social evaluation studies, measures of state anxiety and cognitive appraisal (perception) of anxiety were obtained in both high-stress and non-stress conditions. Measures of social evaluation and physical danger trait anxiety were obtained in a low-stress condition. The interactional model was strongly supported for the physical danger situation. As predicted, high physical danger trait anxiety subjects experienced greater increases in state anxiety than low physical danger subjects proceeding from the non-stress to the high stress physical danger condition. The interaction model was not supported in the social evaluation situation; although not significant, mean levels of state anxiety were in the predicted direction. Results are discussed in the context of person perception and the need for testing personality models in realistic field settings.     

我国民众对SARS信息的风险认知及心理行为

采用分层抽样的调查方法,对全国17个城市的4231名市民进行了SARS疫情中风险认知特征和心理行为的研究。结果发现：（1）负性信息,包括患病信息和与自身关系密切的信息,更易引起民众的高风险认知; 正性信息,包括治愈信息和政府防范措施的信息,能降低个体风险认知水平。（2）我国民众5月中旬风险认知因素空间位置分析结果表明, SARS病因处于不熟悉和难以控制一端,“愈后对身体的影响和有无传染性”处于不熟悉一端,这是引起民众风险意识的主要因素。（3）结构方程分析结果表明,SARS疫情信息是通过风险认知对个体的应对行为、心理健康产生影响的, 并初步验证了风险评估、心理紧张度、应对行为和心理健康等指标对于危机事件中民众心理行为的预测作用     

An examination of mindfulness skills in terms of affect tolerance among individuals with elevated levels of health anxiety

Background and Objectives: Affect tolerance factors, including anxiety sensitivity, intolerance of uncertainty, and emotional distress tolerance, have been implicated in the exacerbation of health anxiety. Therefore, identifying methods to improve affect tolerance in health anxious populations is imperative. Despite the link between mindfulness and greater affect tolerance in non-clinical populations, no work has examined the role of mindfulness skills in terms of affect tolerance among individuals with elevated health anxiety. The aim of the current study was to examine the unique contribution of mindfulness skills in terms of distress tolerance, anxiety sensitivity, and intolerance of uncertainty.

Methods: Participants were 218 undergraduates with clinically elevated levels of health anxiety (75.7% female; M_age?=?19.53, SD?=?3.16, Range?=?18–45) who completed self-report measures for course credit.

Results: Findings indicated that, after controlling for theoretically relevant covariates, greater acting with awareness, non-judgment, and non-reactivity were uniquely associated with greater distress tolerance, and greater non-reactivity was associated with lower levels of intolerance of uncertainty. Though none of the mindfulness skills emerged as specific individual predictors of anxiety sensitivity, these skills collectively accounted for unique variance in anxiety sensitivity.

Conclusions: These findings suggest that mindfulness skills may be helpful in targeting affect tolerance factors among individuals with elevated health anxiety.
