背景资料。偏执狂在临床和非临床人群中的研究越来越多。然而，目前还没有针对迫害思想的多维衡量标准，以供在整个人口--精神病理学连续体中使用。本文报道了《格林等人偏执思维量表》的编制。其目的是设计一种工具，以简单的自我报告形式评估迫害和社会参照的想法，以当前对迫害想法的定义为指导，并纳入对定罪、关注和痛苦的评估。共有353名没有精神病史的人和50名目前有迫害妄想症的人完成了一系列偏执项目和评估效度的额外措施。这些项目是根据最近对迫害妄想症的定义、对偏执狂的当前评估、作者的临床经验设计的，并纳入了定罪、全神贯注和痛苦的维度。非临床组在随访2周时评估重测信度，妄想组在随访6个月时评估临床变化。提取了两个包含16个条目的量表，用于评估社会参照和迫害的想法。量表及其各维度均具有良好的内部一致性和效度。量表对临床变化敏感。研究发现，社会参照与迫害之间存在等级关系。这些数据为妄想症患者和健康人之间的偏执想法的连续体提供了进一步的证据。提出了一种可靠、有效的偏执思维评估工具。它将为研究人员提供一种有效的方法来确保研究的一致性，并为临床医生提供一种评估治疗变化的有效方法。
Background. Paranoia is increasingly being studied in clinical and non-clinical populations. However there is no multi-dimensional measure of persecutory ideas developed for use across the general population-psychopathology continuum. This paper reports the development of such a questionnaire: the 'Green et al. Paranoid Thought Scales'. The aim was to devise a tool to assess ideas of persecution and social reference in a simple self-report format, guided by a current definition of persecutory ideation, and incorporating assessment of conviction, preoccupation and distress.Method. A total of 353 individuals without a history of mental illness, and 50 individuals with current persecutory delusions completed a pool of paranoid items and additional measures to assess validity. Items were devised from a recent definition of persecutory delusions, current assessments of paranoia, the authors' clinical experience, and incorporated dimensions of conviction, preoccupation and distress. Test-retest reliability in the non-clinical group was assessed at 2 weeks follow-up, and clinical change in the deluded group at 6 months follow-up.Results. Two 16-item scales were extracted, assessing ideas of social reference and persecution. Good internal consistency and validity was established for both scales and their dimensions. The scales were sensitive to clinical change. A hierarchical relationship between social reference and persecution was found. The data provide further evidence for a continuum of paranoid ideas between deluded and healthy individuals.Conclusions. A reliable and valid tool for assessing paranoid thoughts is presented. It will provide an effective way for researchers to ensure consistency in research and for clinicians to assess change with treatment.
