项目摘要

DESCRIPTION (provided by applicant): Personality disorders are common in the general population and are particularly prevalent among psychiatric patients. Of concern, personality disorders are associated with a number of adverse outcomes, including suicidality, attenuated treatment response, increased utilization of health care services, and significant functional impairment. It is therefore crucial that clinicians and researchers have tools available to efficiently assess this key aspect of psychological functioning. Unfortunately, many common measures of personality pathology are quite long and inefficient and/or must be administered and scored by professional staff. Moreover, a number of categorical and dimensional models of personality pathology have been proposed, but the lack of integration and comprehensiveness among these models has led to confusion in health care and research settings and has resulted in a decrease in assessment of personality pathology. Thus, in the proposed research, our general aims are to (a) identify a comprehensive and integrative set of dimensions relevant to personality pathology, and (b) develop an efficient computerized adaptive method the CAT-PD to measure these dimensions. Computerized adaptive tests (CATs) are rooted in modern psychometric methods and are designed to select items for administration that are tailored individually to each patient, which typically leads to significant gains in measurement efficiency with little or no cost to test reliability or validity. To accomplish our general goals, we plan a five-phase project in which we (Phase 1) identify the content domains to be assessed and develop the initial item pool based on the public domain International Personality Item Pool (IPIP), (Phase 2) collect self-report item responses from two samples each of psychiatric patients (total N = 500) and community-dwelling adults (total N = 500) and conduct analyses of those responses to develop and cross-validate the CAT-PD scales, (Phase 3) calibrate the CAT-PD items using item response theory (IRT) and conduct CAT simulations to guide construction of the live CAT-PD software, (Phase 4) develop CAT-PD software based on the results of all previous phases, and (Phase 5) conduct a live-testing study of the CAT-PD in a new sample of psychiatric patients (N = 300) to study its efficiency and construct validity and establish cut points and scoring rules designed to increase the tool's practical utility across a wide variety of applied and research settings. It is our hope that the proposed research will help to integrate the numerous dimensional models of personality pathology, yield a comprehensive set and efficient measure of personality disorder dimensions, and contribute to advancements in personality disorder theory, research, diagnosis, and intervention. PUBLIC HEALTH RELEVANCE: Because personality disorders are common in the general population and are associated with a number of adverse outcomes, including suicidality, attenuated treatment response, increased utilization of health care services, and significant functional impairment, the proposed project is relevant to public health. It is crucial that clinicians and researchers have tools available to efficiently assess this key aspect of psychological functioning. The proposed research will help to integrate the numerous models of personality pathology, yield a comprehensive set and efficient measure of personality disorder dimensions, and contribute to advancements in personality disorder theory, research, diagnosis, and intervention.

描述(申请人提供)：人格障碍在普通人群中很常见，在精神病患者中尤为普遍。令人担忧的是，人格障碍与许多不良后果有关，包括自杀、治疗反应减弱、卫生保健服务利用率增加和严重的功能障碍。因此，至关重要的是，临床医生和研究人员有可用的工具来有效地评估心理功能的这一关键方面。不幸的是，许多常见的人格病理学测量方法都相当冗长且效率低下，并且/或者必须由专业人员进行管理和评分。此外，已经提出了一些人格病理学的范畴和维度模型，但这些模型之间缺乏整体性和全面性，导致卫生保健和研究环境的混乱，导致人格病理学评估的减少。因此，在拟议的研究中，我们的总体目标是(A)确定与人格病理学相关的一套全面和综合的维度，以及(B)开发一种有效的计算机化自适应方法CAT-PD来测量这些维度。计算机化自适应测验(CATS)植根于现代心理测量学方法，旨在为每个患者选择单独定制的管理项目，这通常会显著提高测量效率，而几乎不需要花费测试可靠性或效度。为了实现我们的总体目标，我们计划了一个分五个阶段的项目，在这个项目中，我们(第一阶段)确定要评估的内容领域并基于公共领域国际个性题库(IPIP)开发初始题库，(第二阶段)从精神疾病患者(总N=500)和社区成年人(总N=500)各两个样本收集自我报告项目反应，并对这些反应进行分析，以开发和交叉验证CAT-PD量表，(第三阶段)使用项目反应理论(IRT)校准CAT-PD项目，并进行CAT模拟，以指导实时CAT-PD软件的构建，(阶段4)根据之前所有阶段的结果开发CAT-PD软件，以及(阶段5)在新的精神病患者样本(N=300)中对CAT-PD进行现场测试研究，以研究其有效性和构建效度，并建立旨在提高该工具在各种应用和研究环境中的实用价值的切入点和评分规则。希望本研究有助于整合人格病理的众多维度模型，形成一套完整、有效的人格障碍维度测量方法，为人格障碍的理论、研究、诊断和干预等方面的发展做出贡献。公共卫生相关性：由于人格障碍在普通人群中很常见，并与许多不良后果有关，包括自杀、治疗反应减弱、医疗保健服务利用率增加和严重的功能障碍，因此拟议的项目与公共卫生相关。至关重要的是，临床医生和研究人员有可用的工具来有效地评估心理功能的这一关键方面。本研究将有助于整合众多的人格病理模型，形成一套完整、有效的人格障碍维度测量方法，为人格障碍的理论、研究、诊断和干预等方面的发展做出贡献。
