StudyU Platform

Overview

N-of-1 trials are the gold standard study design to evaluate individual treatment effects and derive personalized treatment strategies. Digital tools have the potential to initiate a new era of N-of-1 trials in terms of scale and scope, but fully-functional platforms are not yet available. Here, we present the StudyU platform which includes the StudyU designer and StudyU app. With the StudyU designer, scientists are given a web application to digitally specify, publish, and conduct N-of-1 trials. The StudyU app is a smartphone application with innovative user-centric elements for participants to partake in the published trials and assess the effects of different interventions on their health. Thereby, the StudyU platform allows clinicians and researchers worldwide to easily design and conduct digital N-of-1 trials in a safe manner. We envision that StudyU can change the landscape of personalized treatments both for patients and healthy individuals, as a free collaborative tool for researchers, and as a tool that can be integrated in clinical practice.

StudyU was initiated in Master project in summer 2020: “App-based N-of-1 trials in a clinically-relevant context for personalizing digital health interventions”. 

This project is embedded in different project on N-of-1 trials and digital health interventions, see here for more details.

Details

  • The StudyU platform contains the StudyU designer and the StudyU app, which allow to design and implement, and then to conduct the study, respectively.
  • Ongoing clinical studies that are using StudyU:

    • FAB Study: Free of Antidepressiva - clinical support when stopping the use of antidepressive medication through open-label placebo (link)

StudyMe App

Overview

N-of-1 trials are multi-crossover self-experiments that allow individuals to systematically evaluate the effect of interventions on their personal health goals. Although several tools for N-of-1 trials exist, none support non-experts in conducting their own user-centric trials. Here, we have developed StudyMe, an open-source mobile application that offers users flexibility and guidance in configuring every component of their trials. Through an initial survey with 272 participants, we learned that individuals are interested in a variety of personal health aspects and have unique ideas on how to improve them. In an iterative, user-centered development process with intermediate user tests, we developed StudyMe that features an educational part to communicate N-of-1 trial concepts. A final empirical evaluation of StudyMe showed that all participants were able to create their own trials successfully using StudyMe and the app achieved a very good usability rating. Our findings suggest that StudyMe provides a significant step towards enabling individuals to apply a systematic science-oriented approach to personalize health-related interventions and behavior modifications in their everyday lives.
