On the basis of the analogy between intrusive thoughts and auditory hallucinations established by Morrison et al. [(1995). Intrusive thoughts and auditory hallucinations: a cognitive approach. Behavioural and Cognitive Psychotherapy, 23, 265-280], the present work compares the metacognitive beliefs and processes of five groups of patients (current hallucinators, never-hallucinated people with a diagnosis of schizophrenia, recovered hallucinators, obsessive-compulsive disorder (OCD) patients, and a clinical control group) and a non-clinical group. The results show that of the five metacognitive factors considered in this study, two were found to be different in the current hallucinators group in comparison to any other group in the design. Likewise, it is found that the metacognitive beliefs of the current hallucinators coincide with those of the OCD patients in various factors, particularly that relating to superstition, and this is interpreted as lending support to the model of Morrison et al. (1995). Furthermore, the results are discussed in the light of existing research on Thought-Action Fusion, stressing the role that may be played by superstitious beliefs and magical thinking in auditory hallucinations and OCD.  相似文献

Metacognitive beliefs about the threatening meaning and significance of intrusions are fundamental to the development and maintenance of obsessive-compulsive disorder (OCD) in the metacognitive model (Cognitive therapy of anxiety disorders: a practice manual and conceptual guide, Chichester, UK, Wiley, 1997; Emotional disorders and metacognition: innovative cognitive therapy, Chichester, UK, Wiley, 2000). This predicts that reductions in metacognitive beliefs about intrusions will result in decreased anxiety and compulsions. It was hypothesized that brief (5min) exposure and response prevention configured as a behavioural experiment to challenge metacognitive beliefs would lead to reductions in anxiety, thought fusion beliefs and the urge to neutralize. Furthermore, these reductions would be greater than the effects observed in the same exposure and response prevention task, accompanied by a habituation rationale. The results were consistent with the hypotheses. The clinical implications for the treatment of OCD are discussed.  相似文献

The metacognitive model of psychological disorders suggests that emotional disorders are related to maladaptive metacognitive strategies corresponding to underlying dysfunctional metacognitive beliefs. There is substantial empirical evidence supporting a role of metacognition in psychopathology, but fewer studies have evaluated the metacognitive model using longitudinal data and taken into consideration its differentiation between components and how they are hypothesized to be related to each other. Thus, more specific model evaluation is important as it relates to identifying mechanisms of disorder with a potential to provide clinical advances. In the present study, 868 participants took part in a 4-wave survey and reported on metacognitive beliefs and strategies and anxiety symptoms. Two longitudinal mediation models (forward and reversed causation) were run to test temporal precedence and bidirectional relations. The results indicated that metacognitive beliefs significantly predicted metacognitive strategies, which further predicted anxiety symptoms and mediated the indirect effect in the relationship between metacognitive beliefs and anxiety over time. The relationship between metacognitive beliefs and anxiety symptoms over time were bidirectional, but this relationship was not accounted for by metacognitive strategies. These findings largely support central predictions set forward by the metacognitive model and indicate that metacognitions play a preceding and maintaining role in anxiety.  相似文献

Previous studies have established that obsessive-compulsive disorder (OCD) is characterised by significant levels of distrust in memory (e.g. for actions). Ironically, this lowered confidence is at least in part due to repeated checking, which is assumed to lower perceptual processing and thereby reduces vividness and detail of the recollections. In a previous study, Hermans, D., Martens, K., De Cort, K., Pieters, G., and Eelen, P. [(2003). Reality monitoring and metacognitive beliefs related to cognitive confidence in OCD. Behaviour Research and Therapy, 41, 383-401] observed that OCD is not only characterised by reduced confidence in memory, but also by a similar distrust in attention (Hermans et al., 2003). The present study aimed at replicating and extending this finding. It was observed (a) that patients suffering from OCD showed less confidence in attention and memory than a clinical and a nonclinical control group; (b) that confidence in attention was uniquely related to checking behaviour, and (c) that repeated checking caused increased levels of distrust in attention. In addition, it was observed that cognitive distrust while performing OCD-related actions not only extends to attention, but also to perception. It is argued that research on metacognition in OCD should move beyond the study of memory.  相似文献

Researchers have called for the examination of test anxiety interventions that extend beyond the delivery of individual services by a trained professional. Following from conceptual models and research findings underscoring the importance of metacognitive beliefs to test anxiety, a controlled pilot study examined whether a group format delivery of the attention training technique (ATT) component of metacognitive therapy reduces test anxiety among eighth-grade students. Students completed baseline study measures and were allocated based upon class period to five sessions of ATT (n = 39) or a music listening control (n = 34) delivered within a group format during a school week. Students completed postintervention study measures on the final day of the intervention and completed follow-up study measures approximately 3 weeks following the intervention. As predicted, students receiving ATT reported less postintervention test anxiety than the control when they held stronger baseline metacognitive beliefs about worry. The patterns of findings held at the follow-up and when specifically examining the cognitive (i.e., worry) dimension of test anxiety. Study results suggest that ATT may be a viable test anxiety intervention for students holding heightened metacognitive beliefs about worry. Future directions are discussed.  相似文献

Cognitive models of obsessive-compulsive disorder (OCD) assign a central role to maladaptive beliefs about threat, uncertainty, importance and control of thoughts, responsibility, and perfection. Previous research has demonstrated that such beliefs relate to specific OCD symptoms in a theoretically meaningful way. The aim of the present study was to determine whether these beliefs are endorsed more strongly by OCD patients than by those with other anxiety disorders. Eighty-nine adult OCD patients, 72 anxious control (AC) patients, and 33 nonclinical control (NCC) participants completed a measure of obsessive beliefs as well as measures of depression and trait anxiety. Compared to NCCs and ACs, OCD patients more strongly endorsed beliefs related to threat estimation, tolerance of uncertainty, importance and control of thoughts, and perfectionism, but not inflated responsibility. Using revised, condensed subscales, OCD patients differed from ACs on beliefs about perfectionism and certainty and about importance and control of thoughts, but not on beliefs about threat estimation and inflated responsibility. When controlling for depression and trait anxiety, the OCD and AC group did not differ on most belief domains, except for a belief that it is possible and necessary to control one's thoughts. Results are discussed in light of evolving cognitive-behavioral theories that highlight appraisals of thought control and the use and effectiveness of varying thought control strategies.  相似文献

The metacognitive model of obsessive-compulsive symptoms [Wells, A. (1997). Cognitive therapy of anxiety disorders: A practice manual and conceptual guide. Chichester, UK: Wiley] assigns a necessary causal role to metacognitive beliefs in the development of symptoms. The current study tested the model by evaluating the effects of experimentally manipulating such beliefs. A 2 × 2 factorial design was used. Thirty-two students with high and 32 students with low obsessional symptoms were subject to an experimental (metacognitive belief induction) or control (no metacognitive belief induction) condition. All participants underwent fake EEG recordings and were informed that the EEG could sense hypothalamus activity caused by having thoughts related to drinking. Participants in the experimental condition were told that if such thoughts were detected they may be exposed to an aversive noise. Controls were told that they may hear an aversive noise but this would be unrelated to the thoughts they had. Results showed a significant interaction effect between level of obsessional symptoms and belief induction. Analysis of this effect demonstrated that in the high obsession group, participants in the experimental condition had significantly more intrusions about drinking, time spent thinking about these intrusions and discomfort from them, than controls. There were also significant main effects on some measures, such as effort to control intrusions about drinking, with higher scores in the experimental condition irrespective of levels of obsessional symptoms. Results support the metacognitive model.  相似文献

A recent approach to the cognitive penetrability of perception, i.e. the possibility that perception is shaped top-down by high-level cognitive states such as beliefs and desires, proposes to understand the phenomenon on the basis of its consequences, among which there is a challenge for the epistemic role of perceptual experience in justifying beliefs (Stokes, 2015). In this paper, I argue that some attentional phenomena qualify as cases of cognitive penetrability under this consequentialist approach. I present a popular theory of attention, the biased-competition theory, on which basis I establish that attention is a form of metacognitive regulation. I argue that attention (as metacognitive regulation) involves the right kind of cognitive-perceptual relation and leads to the same epistemic consequences as other more traditional versions of cognitive penetrability.  相似文献

Abstract

There is tremendous interest in understanding the cognitive processes behind obsessive–compulsive disorder (OCD). Whereas previous research on cognitive OCD models has focused on the dysfunctional content of obsessional thinking, processes and styles of thinking have not yet been investigated. The present study investigated the relationship between a ruminative response style and obsessive–compulsive (OC) symptomatology in two non-clinical samples. In Sample 1, 261 students completed the Ruminative Response Scale, the Padua-Inventory, Revised, and the Beck Depression Inventory. Tendency to ruminate was positively correlated with the severity of OC symptoms and particularly with obsessive rumination, even after controlling for depression. Results were replicated in Sample 2 (211 students). Data indicate that a ruminative response style and obsessive rumination share common processual features. Understanding the interaction between rumination and obsessional thinking might help to further elucidate the role of cognitive vulnerability factors in OCD and to expand cognitive and metacognitive models of OCD.  相似文献
