Contamination fear is one of the most common symptoms of obsessive-compulsive disorder (OCD). Exposure and response prevention (ERP) is effective for OCD, but a significant minority of treatment-seeking individuals refuse ERP entirely or drop out prematurely. Research suggests that safety behaviour (SB) may enhance the acceptability of ERP; however, questions remain about how to incorporate SB into existing treatments. Clinical participants with OCD and contamination fear (N = 57) were randomized to receive an exposure session with no SB (ERP), a routinely used SB (RU), or a never-used SB (NU). Significant reductions in contamination fear severity were observed in all conditions. Although omnibus comparisons were only marginally significant, pairwise comparisons revealed some condition differences. NU demonstrated significantly lower self-reported contamination fear severity at post-exposure, as well as marginally higher treatment acceptability ratings. Findings suggest that exposure with SB may be effective and acceptable, and are discussed in terms of cognitive-behavioural theory and treatment of anxiety and related disorders. 相似文献
Objective: Communication of cancer information is an important element of cancer control, but cancer fear may lead to information avoidance, especially when coping is low. We examined the association between cancer fear and cancer information avoidance, and tested whether this was exacerbated by psychosocial stress.Design: Cross-sectional survey of 1258 population-based adults (58–70 years) in England.Main outcome measures: Cancer fear (intensity and frequency), perceived psychosocial stress and cancer information avoidance. Control variables were age, gender, ethnicity, marital status and education.Results: A quarter (24%) of respondents avoided cancer information. Ordinal logistic regression analyses showed main effects of psychosocial stress (OR = 1.17, 95% CI 1.07–1.29) and cancer fear: cancer information avoidance was lowest in those with no cancer fear (13%), followed by those with moderate (24%; OR = 2.15, 95% CI: 1.49–3.12), and high cancer fear (35%; OR = 3.90, 95% CI: 2.65–5.73). In the adjusted model, the interaction between cancer fear and stress was significant (OR = 1.14, 95% CI 1.004–1.29, p < .05): 40% of those with high fear/high stress avoided cancer information compared with 29% with high fear/low stress.Conclusion: Cancer fear and psychosocial stress interact to produce disengagement with cancer-related information, highlighting the importance of affective processes to cancer control efforts. 相似文献
Objective: This study examines the effects of a mammography decision intervention on perceived susceptibility to breast cancer (PSBC) and emotion and investigates how these outcomes predict mammography intentions.
Design: Randomised between-subjects online experiment. Participants were stratified into two levels of risk. Within each stratum, conditions included a basic information condition and six decision intervention conditions that included personalised risk estimates and varied according to a 2 (amount of information: brief vs. extended) × 3 (format: expository vs. untailored exemplar vs. tailored exemplar) design. Participants included 2465 US women ages 35–49.
Main Outcome Measures: PSBC as a percentage, PSBC as a frequency, worry, fear and mammography intentions.
Results: The intervention resulted in significant reductions in PSBC as a percentage for women in both strata and significant increases in worry and fear for women in the upper risk stratum. Of the possible mediators examined, only PSBC as a percentage was a consistent mediator of the effect of the intervention on mammography intentions.
Conclusion: The results provide insight into the mechanism of action of the intervention by showing that PSBC mediated the effects of the intervention on mammography intentions. 相似文献
We used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large (Exps. 1 and 2), spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. However, they hardly managed to do so when the probability differences were small (Exp. 3), and they did not escape from threat more quickly (Exp. 2). In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed. 相似文献
Abstract The growing ill-health in Sweden is related to the crisis of the welfare state and to globalization and the expansion of a new virtual reality affecting the conceptualization of time and space, as well as to wider areas of human interaction, thinking, and ethical judgment. Fear and anxiety are emotional states of mind that have widespread effects on an individual level as well as on the whole of society. 相似文献
ABSTRACTIn the present study, attentional bias was investigated as a potential predisposing mechanism for the contamination-related subtype of obsessive-compulsive disorder (C-OC disorder). Fifty healthy participants with varying degrees of subclinical C-OC symptoms performed a visual search task to measure differential attentional biases elicited by neutral, disgust-, and fear-specific pictorial material. Participants had to find a target picture within five neutral distractor pictures randomly presented on different locations in an array. The task was to decide whether the array contained an unpleasant target picture or not. In randomly-selected emotional trials, participants were further asked about the content of the picture and the confidence of their answer. The results show that the reaction times significantly differed between the emotional and neutral pictures. Participants were significantly more confident in answering questions referring to fear compared to disgust pictures. This effect was marginally amplified in participants with higher C-OC symptoms. We discuss the results within the framework of the cost and benefit hypothesis, which postulates that disgust evolutionarily elicits stronger uncertainty compared to fear, owing to the ambiguous nature of the stimuli. Increased uncertainty might be an important but underestimated factor for pathological disgust experience, such as in obsessive-compulsive disorder. 相似文献
Old, middle-aged and young persons of both genders were presented with slides containing pictorial stimuli that varied in emotional content. Each picture was rated on three dimensions: (1) valence; (2) arousal; and (3) dominance, using a 25-point scale. Heart rate, skin conductance, and forehead and cheek EMG were recorded during each slide presentation. The old and middle-aged groups showed greatly attenuated psychophysiological responses, compared to the young group. However, the old and middle-aged subjects used more extreme ratings than the young subjects on both the valence and arousal dimensions. Females were more valence-sensitive than males, but males in general used more extreme ratings of arousal than females. These results suggest a tendency to report increased felt emotion but decreased physiological response to emotional stimuli across the life span. 相似文献
