Developing computer-based questionnaires (CQs) is challenging. A new approach separates functionality from content, using a generic tool and content-independent data model to improve CQ development and integration.

Area of Science:

Health Informatics
Medical Informatics
Computer Science Applications in Medicine

Background:

Computer-based questionnaires (CQs) offer benefits for data collection and patient acceptance.
Previous CQ projects faced limitations due to dedicated software, funding, and poor integration with medical systems.
Fixed database structures hinder CQ adaptability, requiring data model changes for content updates.

Purpose of the Study:

To address persistent challenges in computer-based questionnaire (CQ) development.
To propose a strategy for creating flexible and integrated CQs.
To overcome limitations of dedicated software and fixed database structures in CQ systems.

Main Methods:

Extended OpenSDE, a generic structured data entry application.

Related Experiment Videos

Developed a tool for constructing and executing CQs.

Implemented a content-independent data model and a generic building tool.

Main Results:

Successfully integrated CQ development capabilities into OpenSDE.
Demonstrated a strategy separating CQ functionality and database structure from content.
Provided a flexible alternative for data input via CQs.

Conclusions:

Combining a generic building tool with a content-independent data model offers an effective solution for CQ development.
This approach mitigates issues related to software dependency, funding, and system integration.
The developed system enhances the adaptability and sustainability of computer-based questionnaire projects.
