概要	A Mobile Research Diary is a data collection technique in which participants record thoughts, experiences, behaviours, or events in structured diary entries submitted via a smartphone or tablet app over a defined study period. By moving the diary onto a mobile device, researchers gain time-stamped, geolocation-optional data captured close to the moment of experience, reducing retrospective recall bias while maintaining the rich, naturalistic quality of traditional diary methods.	The Mobile Experience Sampling Method (ESM) collects repeated, time-stamped self-reports from participants in their natural environment using a smartphone app. By signaling participants multiple times per day over days or weeks, researchers capture psychological states, behaviors, and contexts as they occur — eliminating retrospective bias and revealing within-person dynamics that single-session surveys cannot detect.
