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.

描述（由申请人提供）：随着人们越来越认识到吸毒成瘾的慢性复发性质，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，以支持持续的康复。显然需要开发一种全面的测量工具，以捕捉恢复的多维性。与此同时，在行为研究界，对项目反应理论巨大优势的认识也在迅速增长。这个提议的项目的目标是使用IRT来帮助开发、评估和提供恢复措施的初始有效性证据。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，其中包含一套与康复相关的综合措施。该项目围绕三个具体目标进行组织。我们将应用IRT方法筛选和确定可以从DATOS中现有措施池中增强恢复测量的潜在项目（目标1）。我们将在不同性别或年龄的亚组间调查已开发的恢复量表中潜在的测量非不变性（目的2）。我们还将通过纵向数据分析获得开发的恢复量表的初始效度证据（目的3）。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，而且也将为方法进步带来重大机遇。综上所述，我们相信该研究有潜力为药物成瘾的研究、治疗和评估以及行为测量中的IRT方法做出重大独特的贡献。
