Digital intervention efficacy is closely related to how the users view them. High-quality interventions are perceived as interesting, meaningful, and relevant, which facilitates their efficacy. However, the existing methods for gathering data on user experience are limited in their ability to measure user perceptions remotely over extensive periods.
The novel research from Aalto University creates a new method for measuring digital intervention user experience, CORTO:
- Contextual: The measurement occurs within digital software to mitigate retrospection bias and encourage answering.
- One-item: The measurement includes only one item to encourage answering.
- Repeated: The measurement is done repeatedly over time to understand temporal changes and improve measurement coverage
- Timely: The measurement is presented near the relevant user interaction to facilitate response specificity and relevance
- Open-ended: The measurement is presented as an open-ended question to gather qualitative, experiential insights.
The study compared the new CORTO method with a traditional method of gathering data on user experience, retrospective interviewing. The study revealed how the CORTO method generated more intervention-specific and candid data with relevant ease.
Overall, the present study makes a substantial contribution to digital intervention research. It exhibits how a natively digital method, CORTO, can advance user-centered intervention development.
