Multiple Nights Matter
The diary is designed for longitudinal review; one entry belongs to a specific night or sleep period, and patterns require multiple entries.

Use this background section to understand when the tool fits, how practitioners use it, and what to consider before sharing it with clients.
Descriptive Review Only
The tool shows patterns, variability, and missingness. It does not generate unsupported CBT-I formulas or prescribe a sleep window.
Does this use wearable sleep-stage data?
No. The specified tool captures client-reported sleep diary data, not device-derived sleep staging.
Can clients backfill missed nights?
Yes, when backfill is enabled, late entries keep clear dates so review remains interpretable.
Does the diary calculate sleep restriction recommendations?
No. It supports practitioner review and treatment adjustment, but it does not prescribe changes without supported rules.
