临床医生和研究人员提出，由于有很高的“闭合需要”(NFC)，信念形成的速度很快，可能有助于接受妄想的解释。这项研究的目的是确定NFC是否与妄想症有如此直接的联系。第二个目的是检验NFC是否与妄想相关的推理过程有关，即“跳到结论”。187名精神病患者被招募参加心理治疗的治疗试验(PRP试验)，完成了闭合量表(NFC)、症状测量和概率推理任务。NFC从两个维度来考虑：对简单结构的渴望和对快速、果断答案的偏好。精神病患者报告说，他们不善于做出快速、果断的答案，但更需要简单的结构。NFC与焦虑和抑郁程度有关。NFC与精神病的阳性症状和阴性症状之间存在微弱的联系，但这些联系可以用影响上的差异来解释。NFC评分与仓促下结论无关。与NFC与妄想症直接相关的论点相反，妄想症患者实际上认为自己优柔寡断。没有证据表明NFC--至少根据NFC的评估--可能是妄想症的直接原因。对精神病症状表现的任何潜在影响都是间接的，通过情感调节。不推荐在精神病症状研究中单独使用NFC。(C)2005爱思唯尔有限公司。保留所有权利。
Clinicians and researchers have suggested that rapidity in belief formation, due to having a high 'need for closure' (NFC), may contribute to the acceptance of delusional explanations. The aim of the study is to determine whether NFC has such a direct link with delusions. A secondary aim is to examine if NFC is related to the delusion-associated reasoning process of 'jumping to conclusions'.One hundred and eighty-seven patients with psychosis, recruited for a treatment trial of psychological therapy (the PRP trial), completed the Need for Closure Scale (NFCS), symptom measures, and probabilistic reasoning tasks. The NFCS was considered in terms of its two dimensions: a desire for simple structure and a preference for quick, decisive answers.The individuals with psychosis reported being poor at making quick, decisive answers but required a greater need for simple structure. NFC was associated with levels of anxiety and depression. There were weak links between NFC and both positive and negative symptoms of psychosis, but these were explained by differences in affect. NFCS scores were unrelated to jumping to conclusions.Contrary to the argument that NFC is directly linked to delusions, individuals with delusions actually perceive themselves as indecisive. There was no evidence that NFC-at least as assessed by the NFCS-could be a proximal cause of delusions. Any potential effect on psychotic symptom presentation is indirect, mediated through affect. The use of the NFCS on its own in the study of psychotic symptoms cannot be recommended. (c) 2005 Elsevier Ltd. All rights reserved.
