Previous studies indicate that people respond defensively to threatening health information, especially when the information challenges self‐relevant goals. The authors investigated whether reduced acceptance of self‐relevant health risk information is already visible in early attention allocation processes. In two experimental studies, participants were watching high‐ and low‐threat health commercials, and at the same time had to pay attention to specific odd auditory stimuli in a sequence of frequent auditory stimuli (odd ball paradigm). The amount of attention allocation was measured by recording event‐related brain potentials (i.e., P300 ERPs) and reaction times. Smokers showed larger P300 amplitudes in response to the auditory targets while watching high‐threat instead of low‐threat anti‐smoking commercials. In contrast, non‐smokers showed smaller P300 amplitudes during watching high as opposed to low threat anti‐smoking commercials. In conclusion, the findings provide further neuroscientific support for the hypothesis that threatening health information causes more avoidance responses among those for whom the health threat is self‐relevant. 相似文献
Courage has seen an explosion of research in all branches of psychology, and the most popular measure is Norton and Weiss’s the courage measure (CM). Despite widespread use, limited investigations into its psychometric properties and validity have been performed. To ensure the strength of findings drawn from the scale, the current study performs a theoretical, psychometric, and empirical analysis of the CM. The results demonstrate that the CM has theoretical concerns stemming from the operational definition of courage used during its creation, and may not actually measure courage. Also, the CM was shown to consist of two dimensions separated by regular and reverse coding. Next, the scale demonstrated slight concerns with method effects, and its construct validity was analyzed. Together, the results demonstrate that the CM would benefit from the removal of reverse coded items, and may actually gage persistence despite fear rather than courage. 相似文献
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
