Resum	A longitudinal survey collects structured questionnaire data from the same individuals or units at two or more distinct points in time. By tracking the same respondents across waves, researchers can distinguish genuine change from stable individual differences, establish temporal ordering between variables, and model trajectories of attitudes, behaviors, or outcomes in ways that a single cross-sectional snapshot cannot support.	The Mobile Diary Method is a longitudinal self-report technique in which participants record their thoughts, feelings, behaviors, or events using a smartphone app or mobile platform over a defined study period — ranging from days to months. Rooted in the classic diary method and the Experience Sampling Method, its mobile form enables real-time, in-context capture of experience, dramatically reducing retrospective recall bias compared to one-shot surveys or end-of-day questionnaires.
