PEGASYS (Projet d'Expérimentation Sur la Gamification et Analyse du StorYtelling Sur SKEZIA): Randomized Controlled Trial Assessing the Effect of Storytelling on Questionnaire Completion and Data Quality Within the E-Cohort SKETHIS

SKETHIS is a national e-cohort that serves as an observatory of health-related quality of life in France. Launched in September 2023 by SKEZI, the cohort is built as a secure health-data warehouse hosted on the SKEZIA data-collection solution. While its primary aim is to monitor health-related quality of life, its trajectories and determinants, SKETHIS is also the opportunity for SKEZI to carry out its InnoPRO program, an initiative dedicated to generate new knowledge in the field of e-cohorts.

Gamification, i.e. the integration of game-design elements, such as points, levels, or badges into non-game contexts, has been shown to increase usage, prolong retention and improve adherence to e-health services. Storytelling is a specific gamification tool that employs narrative techniques (voices, story characters, suspense, etc.) to structure a coherent, accessible and engaging participants' experience.

Improving and maintaining participant engagement is a major challenge for large-scale e-cohorts. Although gamification and storytelling have been empirically used to boost participation, the effect of storytelling on self-administered patient reported outcome questionnaires has not been evaluated in a rigorously designed randomized clinical trial.

Purpose of the study To determine whether adding a modest, narrative-driven storytelling introduction to a Patient-Reported Outcome questionnaire increases questionnaire completion without compromising data quality.
