DESCRIPTION (provided by applicant): This Phase II application proposes to continue development of the ASI-MV-CAT, a Computer Adaptive Testing edition of Inflexxion's popular Addiction Severity Index-Multimedia Version (ASI-MV). Built on the ASI, probably the most widely used adult assessment for substance use problems in the US, the ASI-MV provides a reliable, valid and cost-effective version for all clinical and research purposes. The Internet connectivity of ASI-MV Connect allows automated collection of data in a manner that is compatible with clinical and administrative systems. The ASI-MV is currently used at more than 500 sites throughout the country and is administered nearly a hundred thousand individuals annually. Despite its substantial commercial success, the current version of the ASI-MV suffers from some of the psychometric problems inherent in the ASI itself. Developed more than quarter century ago, concerns have mounted about the psychometric performance of the ASI, particularly as evaluated in light of modern thinking. Furthermore, profound changes in the nature of the substances abused, patient populations, and treatments have occurred during the past 25 years. Thus, the ASI and, by extension, the ASI-MV do not meet all critical assessment and treatment needs of administrators, researchers, and clinicians. The ASI-MV-CAT is intended to update the ASI and to provide the option for brief, but state-of-the-art, assessment. The ASI-MV has amply demonstrated the feasibility of using computer- mediated administration of the ASI. Based on principles of Item Response Theory (IRT), a computer adaptive testing (CAT) version of the ASI-MV will permit improvement in several, related measurement concepts: (1) scaling and dimensionality of derived scores, (2) interval measurement of clients' problem severity, (3) overall adherence to scientific measurement principles and hence, (4) applicability of measurement data to statistical analyses. CAT also permits a quick ASI screening or follow-up assessment that could potentially reduce administration time 50% to 80%. In Phase I, the Specific Aims were accomplished utilizing a large database of ASI-MV Connect assessments (N = 23,400). A comprehensive examination of the psychometric (classical test theory-CTT and IRT) status of the existing ASI items for all ASI domains was conducted. While some domain items performed better than others, each domain was found to require updating and improvement. Two pools of potential new items were generated for the employment and psychiatric domains. Phase II will see the completion of four Specific Aims: (1) development and qualitative evaluation of new pools of items for the remaining ASI domains (medical, alcohol, drug, legal, and family/social), (2) comprehensive psychometric analyses of the entire item bank on a large number of clients in treatment for substance use disorders and a community, non-clinical sample, (3) creation of a fully functioning prototype of an ASI-MV-CAT, and (4) empirical tests of validity and sensitivity to change of the ASI-MV-CAT. These steps will result in a new and more powerful version of the ASI that will represent a significant advance in the evolution of this important tool. PUBLIC HEALTH RELEVANCE: The ASI is the gold standard assessment for individuals in substance abuse treatment. Since its creation, changes in the substances abused, patient populations, treatments, and psychometric standards suggest the need for an updated version. The proposed ASI-MV-CAT would address this need and permit flexible and efficient administration options, updated content, and could be rapidly disseminated. The ASI-MV-CAT will have major public health importance and significant commercial potential.

描述（由申请人提供）：本II阶段申请建议继续开发ASI-MV-CAT，这是Inflexxion流行成瘾严重性指数 - Multimedia版本（ASI-MV）的计算机自适应测试版。 ASI-MV建立在ASI上，这可能是美国用于吸毒问题的成人评估，为所有临床和研究目的提供了可靠，有效和成本效益的版本。 ASI-MV Connect的Internet连接允许以与临床和管理系统兼容的方式自动收集数据。目前，ASI-MV在全国500多个站点上使用，每年被授予近十万人。尽管ASI-MV的当前版本却遭受了ASI本身固有的一些心理测量问题，但目前的ASI-MV版本却遭受了巨大的商业成功。在四分之一多世纪以前，人们一直对ASI的心理测量表现感到担忧，特别是根据现代思维的评估。此外，在过去的25年中，发生了滥用物质，患者人群和治疗方法的深刻变化。因此，ASI以及ASI-MV不满足管理员，研究人员和临床医生的所有关键评估和治疗需求。 ASI-MV-CAT旨在更新ASI，并提供简短但最先进的评估的选项。 ASI-MV充分证明了使用计算机介导的ASI给药的可行性。基于项目响应理论（IRT）的原理，ASI-MV的计算机自适应测试（CAT）版本将允许改进几种相关的测量概念：（1）派生得分的缩放和维度，（2）对客户问题严重性的间隔测量，（3）（3）对科学测量的总体测量原理原理和范围分析的总体测量能力（4）分析量量量量表，（4）分析量量量表的数据量（4）。 CAT还允许快速进行ASI筛查或随访评估，该评估可能会减少50％至80％。在第一阶段，使用大型ASI-MV连接评估数据库实现了具体目标（n = 23,400）。对所有ASI领域的现有ASI项目的心理测量学（经典检验理论-CTT和IRT）的全面检查均已进行。尽管某些域项目的性能要比其他项目更好，但发现每个域都需要更新和改进。为就业和精神病领域生成了两个潜在的新项目。第二阶段将看到四个具体目的的完成：（1）对剩余ASI域（医疗，酒精，药物，法律和家庭/社会/社会）的新项目的开发和定性评估，（2）全面对整个项目的心理测量分析的全面心理测量分析，对大量客户进行了大量的客户，用于吸毒和非临床的型号（3），并且是临床的，（3），并完全创建了一个功能（3），并有效地创建了一个功能，该工具是一种有效的工具，是一种有效的工具。 （4）有效性和对ASI-MV-CAT改变的敏感性的经验检验。这些步骤将导致ASI的新版本，这将代表此重要工具的发展中的重大进步。 公共卫生相关性：ASI是药物滥用治疗中个人的黄金标准评估。自创建以来，滥用物质的变化，患者人群，治疗和心理测量标准表明需要更新版本。拟议的ASI-MV-CAT将满足这一需求，并允许灵活，有效的管理选项，更新内容，并且可以迅速传播。 ASI-MV-CAT将具有重要的公共健康重要性和巨大的商业潜力。
