Specific and differential prediction of health anxiety by disgust sensitivity and propensity

Current models of health anxiety suggest that fear resulting from false alarms to perceived threats to one's health results in the development of hypochondriasis and related disorders. Disgust has been proposed as an affective response that may function as an etiological and maintenance mechanism in health anxiety. Moreover, the way in which an individual perceives the disgust response (disgust sensitivity) may affect health anxiety, separately from their likelihood of experiencing disgust (disgust propensity). The present study utilized multiple hierarchical regression analysis to investigate the degree to which self-reported disgust sensitivity and disgust propensity differentially predict elevated health anxiety in a sample of 620 non-treatment-seeking undergraduates. Further, this effect is tested in comparison to that of anxiety sensitivity, a construct demonstrated to be strongly related to health anxiety. Analyses indicate that disgust sensitivity, rather than disgust propensity, is primarily responsible for this relation. An additional analysis tested the specificity of disgust sensitivity relative to anxiety sensitivity. Disgust sensitivity was no longer significant after including anxiety sensitivity in the model. Suggestions for further evaluation of this relation are provided. These results suggest that although disgust sensitivity may appear related to health anxiety, this relation may be confounded by anxiety sensitivity.     

行为免疫系统对个体就医行为倾向的影响

研究首次考察了行为免疫系统与个体就医行为倾向的关系。3个研究一致显示：行为免疫系统特质性激活水平较高的个体更容易对就医持消极态度和延迟就医; 情境性激活行为免疫系统会使得个体更不愿意就医和更倾向于延迟就医; 且行为免疫系统激活对就医态度和就医延迟倾向的影响以对就医感染风险的感知为中介。这支持了进化失配假说, 提示行为免疫系统对现代医学可能缺乏进化的适应性, 并为理解现代人类就医行为提供了新的理论视角。     

无聊倾向对青少年网络成瘾的影响：一个有调节的中介模型

为探究无聊倾向对青少年网络成瘾的预测作用和影响机制,选取云南省和山东省5所普通中学的1553名青少年进行调查。结果发现：（1）青少年无聊倾向显著正向预测网络成瘾;（2）学习倦怠在青少年无聊倾向与网络成瘾之间起中介作用;（3）积极应对方式在无聊倾向与学习倦怠之间起调节作用。本研究结果揭示了青少年网络成瘾形成的内部机制,并基于I-PACE模型构建了青少年网络成瘾的形成过程模型,为青少年网络成瘾的干预提供决策依据。     

Force versus fury: Sex differences in the relationships among physical and psychological threat potential,the facial width‐to‐height ratio,and judgements of aggressiveness

Individuals with larger facial width‐to‐height ratios (FWHRs) are judged as more threatening, and engage in more threat‐related behavior, than do individuals with smaller FWHRs. Here we identified components of threat potential that are related to the FWHR. In Study 1, the FWHR was correlated positively with physical threat potential (bicep size) in women and with both physical and psychological (anger proneness) threat potential in men. Behavioral aggression was measured in a subset of these participants using the Point Subtraction Aggression Paradigm (costly aggression) and a Money Allocation Task (non‐costly aggression). Psychological (but not physical) threat potential predicted non‐costly aggression and physical (but not psychological) threat potential predicted costly aggression. In Study 2, a separate set of participants judged the anger proneness, strength, or aggressiveness of male participants photographed in Study 1. Participants’ judgements of all three characteristics were associated with the FWHR, and there were sex differences in how aggressiveness was conceptualized (for women, aggressiveness was associated with anger proneness, for men, aggressiveness was associated with strength). These results are consistent with the hypothesis that the FWHR may be an adaptation to cue the threat potential of men.

     

Changes in Problematic Anger,Shame, and Disgust in Anxious and Depressed Adults Undergoing Treatment for Emotion Dysregulation

Emotion dysregulation, the pervasive difficulty managing negative emotions, is a core problem across mood and anxiety disorders. Anger, shame, and disgust are particularly problematic emotions, impacting both disorder severity and treatment outcome. We previously found that a 16-week dialectical behavior therapy skills training group (DBT-ST) was superior to an activities-based support group (ASG) in decreasing emotion dysregulation in 44 adults with high emotion dysregulation who met diagnostic criteria for an anxiety or depressive disorder. We presently examine these participants’ changes in anger, shame, disgust, and distress using self-reports collected over 6 months during and after treatment. Hierarchical linear modeling analyses show that DBT-ST was superior to ASG in decreasing anger suppression (d = 0.93) and distress (d = 1.04). Both conditions significantly reduced shame, disgust propensity, and disgust sensitivity, but neither was superior for these outcomes. The treatments did not significantly reduce anger expression. Mediation analyses suggest that condition indirectly influenced 4-month anger suppression, shame, and distress through its effect on 2-month emotion dysregulation. These findings suggest that DBT-ST is efficacious for certain problematic emotions and distress in depressed and anxious adults and that common factors may account for some, but not all, of its benefits.     

The relationship between false confessions and perceptions of parental rearing practices

The main aim of the study was to investigate the relationship between a history of having made a false confession and reported parental rearing practices. It was hypothesized that the reporting of rejection and absence of warmth by parents would be associated with the making of a false confession. The participants were 804 college students in Iceland. Each was asked about false confessions made to teachers and parents in the past, as well as about false confessions made to the police during questioning. The participants completed questionnaires relating to perceived parental rearing practices (EMBU), proneness to antisocial behavior (the Gough Socialization Scale), personality (EPQ), self-esteem (Rosenberg), and compliance (GCS). Only eight participants (1% of those interrogated) claimed to have made false confessions to the police, whereas 10% claimed to have made false confessions to teachers or parents. False confessions were significantly associated with proneness to antisocial behavior and the EMBU Rejection and Warmth scales for both fathers and mothers.     

Individual differences in nostalgia proneness: The integrating role of the need to belong

Who is the nostalgia-prone person? The ‘sociality view’ sees an individual who frequently recalls meaningful memories rich in social content. The ‘maladaptation view’ sees an emotionally unstable, neurotic individual. In four studies, we integrated these contrasting views. We hypothesized that the link between neuroticism and nostalgia proneness arises because (a) neuroticism is associated with the need to belong and (b) the need to belong triggers nostalgia, with its abundant social content. Consistent with this hypothesis, Studies 1–2 found that the correlation between neuroticism and nostalgia proneness was eliminated when controlling for the need to belong. The need to belong predicted increased nostalgia proneness, above and beyond neuroticism. Specifically, Study 2 revealed that a deficit-reduction (rather than growth) belongingness orientation predicted increased nostalgia proneness. When the role of this deficit-reduction belongingness orientation was controlled, the positive correlation between neuroticism and nostalgia disappeared. Studies 3–4 showed that experimental inductions of a belongingness deficit augmented nostalgia, providing support for its compensatory role.     

Disgust sensitivity and fear of animals: Effect of exposure to violent or revulsive material

Subjects were asked to rate their fear of four categories of animals both before and after viewing one of three brief video films. Subjects watched either (a) a video depicting extreme violence, (b) a video depicting revulsive scenes from a hospital operation, or (c) a video showing neutral landscape scenes. The results suggested that exposure to violent material produced an increase in fear ratings for animals in the Hi Fear/Hi Predatory category (e.g., lion, tiger, shark) which was significantly different from a decrease in fear ratings recorded for all other categories of animals. However, exposure to revulsive material produced an increase in fear ratings to animals in both the Hi Fear/Lo Predatory category (e.g., rat, spider, snake) and the Hi Revulsion category (e.g., slug, maggot, snail) which was significantly different to the decrease in fear ratings recorded for animals in the remaining categories. The neutral landscape scenes produced a decrease in mean fear ratings for all categories of animals. These results are considered further support for a disease-avoidance model of common animal fears, and suggest a causal link between disgust sensitivity and fear of certain fear-relevant animals.     

Emotion regulation,disgust sensitivity,and psychophysiological responses to a disgust-inducing film

Abstract

Using a disgust-inducing film, Gross (1998) showed that the instruction to suppress mimic expression (suppression) triggered physiological arousal, while the instruction to think about the film in order to adopt a detached and unemotional attitude (reappraisal) reduced affective strain compared to a condition instructing subjects simply to watch the film (watch). The present paper investigates, if disgust sensitivity has a moderating role in this context. Physiological, subjective, and behavior responses were recorded in 120 males divided according to high/low disgust sensitivity who were exposed to the disgust-inducing film used by Gross. The instruction effects reported by Gross could not be replicated. However, high disgust-sensitive subjects were more physiologically and emotionally aroused than low disgust-sensitive subjects. Interactions between disgust sensitivity and the three film instructions can possibly be traced back to a repressive coping style of subjects with low disgust sensitivity.     

Punitive emotions and norm violations

The recent literature on social norms has stressed the centrality of emotions in explaining punishment and norm enforcement. This article discusses four negative emotions (righteous anger, indignation, contempt, and disgust) and examines their relationship to punitive behavior. I argue that righteous anger and indignation are both punitive emotions strictly speaking, but induce punishments of different intensity and have distinct elicitors. Contempt and disgust, for their part, cannot be straightforwardly considered punitive emotions, although they often blend with a colder form of indignation to favor low-cost, indirect, and collective forms of punishment such as mockery, exclusion, and ostracism.
