# Diary Study Plan

Study what people do over weeks, not in one sitting

## What this does

The behaviour you want to understand happens over days or weeks, so watching someone once will not show it. This helps you plan a diary study: what you ask participants, how often and for how long, who you recruit, and how you will make sense of the entries. Reach for it when a single session is the wrong shape.

### Top 3 things it does for you

- Plan a diary study end to end
- Write the prompts participants respond to
- Decide cadence, duration and who takes part

## About Diary Study Plan

Some behaviour only shows itself over days or weeks. This designs a diary study for it: the prompts, the cadence, the duration, the participant criteria, and the frame you will analyse the results with.

If the behaviour fits inside one sitting, a usability test plan is the better fit.

## Questions

### Is Diary Study Plan safe to install?

AIR scanned this exact version of Diary Study Plan and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 20e34c4a587e, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/diary-study-plan.
