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
