Adaptest - 项目响应理论分析软件

Adaptest是基于Adaptest计算机化自适应测试和项目响应理论（IRT）的评分软件包，旨在轻松集成到现有的电子数据收集（EDC）系统中。实现范围可以从Web开发人员快速使用Adaptest作为纯HTML和JavaScript Web 2.0应用程序的插件，到与引擎的Linux二进制文件或Windows dll的完整系统集成。无论实施如何，Adaptest 都提供了广泛的功能和优势：

Adaptest 允许在秤开发过程中获得统计信息，以更好地为评估过程提供信息。

• 更多评估依靠“现代测量理论”进行发展
• 无需因为数据收集系统无法使用 IRT 信息而依赖较差的总和分数
• 可以提高统计功效，从而减少样本量需求

Adaptest允许使用现代测量理论（IRT / Rasch）开发的任何评估以固定长度的形式呈现并实时评分。

• 无需对数据进行后处理
• 与传统方法相比，提供更具统计有效性的分数
• 更加以患者为中心的评估
• 减轻患者负担
• 保持与全长评估相当的可靠性和有效性

基于自适应项目响应理论的计算机化自适应测试软件专为EDC系统集成而设计。

• 量表分数集成到数据收集和传输过程中
• 位于您了解和信任的基础架构中
• 无需学习或维护新系统
• 您当前的支持人员仍然是您联系的人

英文介绍:

The Adaptest computerized adaptive testing and item response theory (IRT)-based scoring software package is designed to be easily included into existing electronic data collection (EDC) systems. Implementation can range from a web developer quickly using Adaptest as a plugin for a purely HTML and JavaScript web 2.0 application to a full system integration with the engine’s Linux binaries or Windows dll. Regardless of implementation Adaptest offers a wide range of capabilities and benefits:

Adaptest allows statistical information obtained during scale development to better inform the assessment process.

• More assessments are relying on “modern measurement theory” for development
• No need to fall back on inferior summed scores because of a data collection system that cannot use IRT information
• Can increase statistical power thereby reducing sample size needs

Adaptest allows any assessment developed using modern measurement theory (IRT/Rasch) to be presented in fixed-length form and scored in real-time.

• Removes the need to post-process data
• Provides more statistically valid scores compared to classical methods
• Assessments that are more patient-centered
• Reduces patient burden
• Maintains comparable reliability and validity to full-length assessments

Adaptest item response theory-based computerized adaptive testing software was specifically designed for EDC system integration.

• Scale scores are integrated into the data collection and transfer process
• Housed within an infrastructure you know and trust
• No new systems to learn or maintain
• Your current support staff is still who you contact
