A central theoretical principle guiding cognitive therapy is that mediation by cognitive processes is linked to the successful treatment of depression. The most recent review of the literature on this question is over a decade old and was suggestive of cognitive mediation for cognitive therapy, but was not conclusive. Since this review, a number of studies have been published that address cognitive mediation. The mediation hypothesis can be broadly defined as encompassing two related questions: cognitive mediation framed as “are cognitive changes associated with therapeutic improvement,” and cognitive specificity from the perspective of “are changes in cognition specific to cognitive therapy?” This latter question is particularly important when cognitive therapy is compared to pharmacotherapy. This article reviews the current literature associated with these questions. Our review indicates that the current body of research generally supports cognitive mediation, but is considerably more mixed for cognitive specificity. However, some evidence suggests that cognitive changes associated with pharmacotherapy are more superficial than those associated with cognitive therapy.  相似文献

Joiner's article (this issue) is a welcome contribution toward clarifying the role of interpersonal factors underlying depression chronicity. We believe, however, that three issues need to be considered regarding an interpersonal research agenda. First, Joiner's proposal would benefit from a discussion of the evidentiary requirements that risk factors must meet. Second, our reading of the literature suggests that interpersonal processes interact with cognitive processes that involve the activation of depressive knowledge structures and that these processes do meet criteria as a possible causal risk factor. Finally, Joiner's global concept of depression chronicity fails to recognize important differences in the mechanisms underlying each of the phenomena of episode prolongation, relapse induction, and recurrence as well as the changes that might occur in these processes with repeated episodes.  相似文献

Greater knowledge of the mechanisms underlying cognitive change in the context of depression is an important goal of current clinical research. The thoughtful review by Garratt, Ingram, Rand, and Sawalani (2007) highlights the wealth of research that has been conducted in this area, while also drawing attention to the many complexities inherent in studying the cognitive mediation hypothesis in cognitive therapy. In this commentary, we use the review by Garratt et al. as a starting point from which to highlight some of the issues that we believe to be imperative to the advancement of knowledge in this field of research. These issues include the need for strong connections between theories of cognitive mediation and depression, the deployment of appropriate research paradigms and methods to advance the field, and the conduct of research in contexts that are relevant to clinical practice.  相似文献

A total of 40 patients with ischemic heart disease undergoing aortocoronary shunting surgery in conditions of cardiopulmonary bypass were studied. Parameters of the P300 cognitive evoked potentials were studied before surgery and 7–9 days after surgery. Neurological and neuropsychological assessments were also performed. The most significant parameters of the P300 potential were found to be the latencies of the P3 and N2 components, increases in which showed positive correlations with the extent of the developing cognitive deficit. Evidence supporting the neuroprotective effects of Trasylol given during surgery was obtained. Patients given Trasylol showed less marked cognitive deficit and smaller changes in P300 parameters. Analysis of the P300 cognitive evoked potential can be recommended for detecting early cognitive dysfunction and assessing the efficacy of neuroprotective therapy in patients undergoing surgery with cardiopulmonary bypass. __________ Translated from Zhurnal Nevrologii i Psikhiatrii imeni S.

认知治疗对偏执型精神分裂症患者恢复期的疗效对照研究   总被引:10,自引:1,他引:9  
目的:探讨认知治疗对偏执型精神分裂症的治疗效果。方法:将符合CCMD-2偏执型精神分裂症诊断标准的患者60例随机分为两组,在治疗恢复期时分别给予精神药物治疗配合认知心理治疗及精神药物治疗配合支持性心理治疗,出院后跟踪随访两年比较疗。结果:两组间社会功能缺陷及日常生活能力的比较无显著差异,出院后两年的病情复发率认知治疗组明显低于对照组(p<0.05)。病情复发的原因主要为不服从治疗、中断药物治疗所致。结论:认知治疗可提高精神分裂症患者对疾病的认识能力,提高患者服从治疗的依从性,因此可改善远期疗效。  相似文献

In an earlier article, Ilardi and Craighead (1994) suggested that symptom change in cognitive behavior therapy (CBT) occurs too rapidly to be the product of efforts at cognitive modification. In a subsequent response, Tang and DeRubeis (this issue) point out that considerable attention is paid to just such cognitive strategies during early sessions of CUT and that the typical strategy of providing twice weekly sessions allows ample time for cognitive restructuring. These observations accord nicely with the theory and nature of cognitive therapy, which encourages patients to use their own behaviors to test the accuracy of their beliefs. Moreover, Tang and DeRubeis note that individual response is as likely to be discrete and abrupt as continuous over time. Just why this is so remains unclear, but it may be related to the sudden realization by patients that they can use cognitive theory as a tool to deal more effectively with life's problems.  相似文献
