Traditional randomised controlled trials (RCTs) often do not adequately capture change during treatment, largely due to limitation inherent to RCT methodology. One such limitation is the use of infrequently administered outcome assessments, which do not have the precision to predict or measure outcomes. These measures often do not possess the temporal resolution necessary to assess individual-level change in neurobehavioral symptoms that vary by time and context (e.g., cognitive performance different at home vs. in the clinic). The NeuroUX app is designed to make it easier for researchers to use mobile technologies to study cognitive processes over time, in the β€œreal world.” Our platform is currently being used in several federally-funded studies, including RCTs. The NeuroUX app supports: - Mobile cognitive testing, - Experience sampling - Ecological momentary assessments (EMA; full-length surveys or microEMA methodology) - Investigator dashboard’ with scheduling functionalities and real-time access to data. Why NeuroUX? - Gamified Experience - HIPAA Compliant - Offline Support - Intuitive Interface - Custom Protocols - Flexible Reminders Key cognitive domains assessed: - Attention - Memory - Executive Function - Emotion & Social Cognition - Psychomotor Speed This app is only for use by registered study participants.
