概要	The online research diary method is a data collection technique in which participants document their experiences, thoughts, or behaviours in structured or open-ended digital diary entries over a defined period. Delivered via email, web forms, blogging platforms, or dedicated apps, it captures temporally proximate, naturalistic data that retrospective interviews cannot provide. It is widely used in health research, education, psychology, and social sciences.	The diary method is a data-collection technique in which participants record their thoughts, behaviours, events, or experiences in their own words at regular or event-contingent intervals over a defined study period. By capturing data close in time to the event, diaries reduce retrospective recall bias and give researchers access to the texture of everyday life as it unfolds — something one-off surveys and retrospective interviews cannot provide.
