Diary studies ask participants to record their experiences, thoughts, and behaviours at regular intervals over an extended period, often days or weeks. This longitudinal approach captures how experience changes over time and surfaces the everyday moments that one-off research sessions inevitably miss. Unlike interviews conducted after the fact, diary entries are recorded close to the moment of experience, which dramatically reduces recall bias and captures the texture of daily life with far greater fidelity.
