RESUMEN
BACKGROUND: Patient and family engagement is thought to improve the quality and relevance of child health research. We developed and evaluated the usability of Patient Engagement 101, an e-learning module designed to strengthen the patient-oriented research readiness of health care professionals, researchers, trainees and other stakeholders. METHODS: The development of Patient Engagement 101 was co-led by a parent and a researcher and overseen by a diverse multistake-holder steering committee. The module was refined and evaluated using a mixed-methods usability testing approach with 2 iterative cycles of semistructured interviews, observations and questionnaires. We collected module feedback by way of semistructured interviews, the validated System Usability Scale, and satisfaction, knowledge and confidence questionnaires. Thematic coding of transcripts and field notes, informed by team discussions, guided the module revisions. RESULTS: Thirty end-users completed usability testing (15 per cycle). In each cycle, we modified the module with respect to its content, learner experience, learner-centred design and aesthetic design. Participants were highly satisfied, and System Usability Scale scores indicated the module had the best imaginable usability. Substantial increases in the participants' knowledge test scores and the confidence to engage in patient-oriented research, but not self-rated knowledge, were observed after module completion. INTERPRETATION: Codevelopment with patients and caregivers, and refinement through comprehensive end-user testing, resulted in a training resource with exceptional usability that improved knowledge and confidence to engage in patient-oriented research in child health. Patient Engagement 101 is openly available online, and the methods used to develop and evaluate it may facilitate the creation and evaluation of similar capacity-building resources.
