The U-CARE portal is one of the government’s strategic research programs at Uppsala University with the purpose of reducing the psychosocial ill health of patients and families in the context of physical illness. “Monitor” is a prototype of an event log filtering tool that will be used by health staff when moderating the content posted to the U-CARE portal. A usability test has been conducted in order to evaluate to what extent of ease users can find and sort relevant information through Monitor. The test involved ten participants who received three sets of tasks each. Results indicate that although the majority of the participants managed to complete all tasks, they did so with errors which could be related to design flaws in the interface. All errors made do however call attention to the early stage of Monitor, which opens up for future improvements. Accordingly, the report concludes by suggesting future directions for further development of Monitor.
