概要	The online diary method is a longitudinal data collection technique in which participants record their thoughts, experiences, behaviors, or events in structured or semi-structured entries submitted via digital platforms — such as web forms, email, or dedicated apps — at regular or event-contingent intervals. It combines the ecological validity of traditional diary research with the logistical advantages of remote, automated data collection.	The Longitudinal Diary Method is a data collection technique in which participants record experiences, thoughts, feelings, or behaviors in structured diary entries repeatedly over an extended period — from days to months or even years. Unlike a one-shot survey, it tracks within-person change, daily fluctuation, and temporal processes in natural settings, making it especially powerful for studying how phenomena evolve over time.
