The present investigation examines the incremental association between disgust propensity and sensitivity and contamination-based obsessive-compulsive disorder (OCD) symptoms. Structural equation modeling in Study 1 indicated that general disgust was related to contamination fear even when controlling for negative affect in a nonclinical sample. Evidence was also found for a model in which the effect of negative affect on contamination fear is mediated by general disgust. Study 1 also showed that both disgust sensitivity and disgust propensity uniquely predicted contamination fear when controlling for negative affect. Growth curve analyses in Study 2 indicated that higher baseline contamination fear is associated with less reduction in contamination fear over a 6-week period as disgust sensitivity increases even when controlling for negative affect. Lastly, disgust propensity was associated with concurrent levels of excessive washing symptoms among patients with OCD in Study 3 when controlling for depression. Implications of these findings from nonclinical, analogue, and clinical samples for future research on the specificity of disgust-related vulnerabilities in the etiology of contamination concerns in OCD are discussed. 相似文献

Cognitive-behavioral treatment for panic disorder relies heavily on interoceptive exposure. Specifically, therapists induce physical symptoms associated with panic in order to produce habituation to those sensations. Many common symptoms of panic are easily induced, such as increased heart rate and dizziness. However, depersonalization is a difficult symptom to induce in the office. Three uncontrolled cases are presented here where a novel intervention, the use of 3D glasses, was used to successfully induce depersonalization with positive effect. The application of the procedure resulted in rapid habituation within session, and all three patients had significant reductions in panic following treatment. Additional research is necessary to examine the application of this, and other, novel methods for inducing depersonalization as part of a comprehensive approach to treating panic and other psychiatric conditions where depersonalization is present. 相似文献

The effects of d-amphetamine on punished responding were studied in two experiments. In Experiment I, pigeons responded under a multiple fixed-ratio 30 response fixed-interval 5-min schedule of food presentation with 60-sec limited holds in both components. Each response was punished with electric shock, the intensity of which was varied systematically. In Experiment II, another group of pigeons responded under a multiple fixed-interval 5-min fixed-interval 5-min schedule of food presentation with 40-sec limited holds. Each response was punished with shock during one component, and every thirtieth response was punished in the other component. d-Amphetamine increased overall rates of punished responding only rarely under any of the punishment conditions; however, response rates within the fixed-interval when rates were low were increased by d-amphetamine when the shock intensity was low (Experiment I), or when responses produced shock intermittently (Experiment II). The data suggest that the effects of d-amphetamine on punished responding depend on the control rate of responding, the punishment intensity, the punishment frequency, and the schedule of food presentation. 相似文献

Although cognitive avoidance has been linked to generalized anxiety disorder (GAD), the mechanism that may account for this association has not been fully elucidated. The current study uses structural equation models to evaluate the relationship between cognitive avoidance and symptoms of GAD in a large unselected sample (n = 1220), and to examine whether subjective fear of emotion partially mediate this relationship. Results support partial mediation, and follow-up analyses suggest that the pattern of relations among fear of emotion, cognitive avoidance, and GAD symptoms is invariant for men and women. However, subsequent analysis revealed equivalence of meditational models where cognitive avoidance leads to GAD symptoms and vice versa. The implications of these findings for better understanding the etiology, maintenance, and treatment of GAD are discussed. 相似文献
