Measurement of Recovery from Drug Addiction LC

说明(由申请人提供)：随着对吸毒成瘾的慢性复发性质的日益认识，国家正在努力促进重新设计和发展以康复为导向的护理系统，以支持持续康复。显然需要开发一种全面的衡量工具，以反映复苏的多维情况。与此同时，行为研究界对项目反应理论(IRT)的巨大优势的认识也在迅速增长。这个拟议项目的目标是使用IRT来帮助开发、评估并为恢复措施提供初步的有效性证据。为了实现这一目标，我们将对国家药物滥用治疗结果研究(即包括成人患者的DATOS和包括青少年患者的DATOS-A)收集的数据进行二次分析，其中包含一套全面的与康复有关的措施。该项目围绕三个具体目标组织。我们将应用项目反应时间方法来筛选和确定可加强从Datos(目标1)现有措施池中恢复的衡量标准的潜在项目。我们将在按性别或年龄定义的亚组(目标2)中调查已开发的恢复量表中潜在的测量不变性。我们还将通过纵向数据分析(目标3)获得制定的回收规模的初步有效性证据。最先进的IRT方法的应用将导致心理测量学上健全的恢复措施，形成一个可以不断改进的坚实基础。此外，应用IRT来解决成瘾研究中的测量问题不仅具有实质性的创新性，而且将为方法学的进步带来重大机遇。综上所述，我们相信拟议的研究有可能对药物成瘾的研究、治疗和评估以及行为测量的IRT方法做出重大而独特的贡献。 公共卫生相关性：对戒毒康复的合理衡量对治疗系统应如何构建、提供和评估具有重要意义。这项拟议的研究将开发一种改进的恢复措施，并将收集所制定的恢复措施的初步有效性证据。改进后的措施与公共卫生有关，因为它将改进对药物滥用相关服务的监测和评估，这些服务旨在启动和促进戒毒。

DESCRIPTION (provided by applicant): With an increased recognition of the chronic relapsing nature of drug addiction, national efforts are being made to foster the redesign and development of recovery-oriented system of care in order to support sustained recovery. There is a clear need to develop a comprehensive measurement tool that captures the multidimensionality of recovery. Meanwhile, awareness of the enormous advantages of Item Response Theory (IRT) is growing rapidly in the behavioral research community. The goal of this proposed project is to use IRT to help develop, evaluate, and provide initial validity evidence for a measure of recovery. To achieve this goal, we will conduct secondary analyses on data collected in the national Drug Abuse Treatment Outcome Studies (i.e., DATOS that includes adult patients, and DATOS-A that includes adolescent patients) which contain a comprehensive set of measures pertinent to recovery. The project is organized around three specific aims. We will apply IRT methods to screen and identify potential items that can enhance the measurement of recovery from the existing pool of measures in DATOS (Aim 1). We will investigate potential measurement non- invariance in the developed recovery scale across subgroups defined by gender or age (Aim 2). We will also obtain initial validity evidence of the developed recovery scale via longitudinal data analysis (Aim 3). The application of the state-of-the-art IRT methodology will lead to a recovery measure that is psychometrically sound, forming a solid foundation that can be continuously improved upon. In addition, the application of IRT to solve measurement problems in addiction research is not only substantively innovative, but would lead to significant opportunities for methodological advancements as well. Taken together, we believe the proposed study has the potential for making significant unique contributions to drug addiction research, treatment and evaluation, and to the IRT methodology in behavioral measurement. PUBLIC HEALTH RELEVANCE: A sound measure of recovery from drug addiction has important implications for how treatment systems should be structured, delivered, and evaluated. This proposed research will develop an improved measure of recovery, and will gather initial validity evidence of the developed recovery measure. The improved measure is relevant to public health as it will improve monitoring and evaluation of substance abuse-related services designed to initiate and promote recovery from addiction.
