CBT-I Sleep Diary: How Therapists Track Sleep Efficiency

What Is a CBT-I Sleep Diary?

A CBT-I sleep diary is a daily log of sleep timing, awakenings, naps, sleep quality, and related behaviors. It helps therapists and clients work from recent data instead of memory alone.

For insomnia work, the diary often matters more than one dramatic night. Patterns across the week show whether the client is spending too much time in bed, napping late, waking for long periods, or keeping irregular sleep and wake times.

CoralEHR's free CBT-I Sleep Diary calculates total sleep time, time in bed, and sleep efficiency from a weekly diary.

What to Track

A practical sleep diary usually includes:

• bedtime
• lights-out time
• estimated sleep latency
• number of awakenings
• wake after sleep onset, often called WASO
• final wake time
• time out of bed
• naps
• sleep quality
• caffeine, alcohol, medication, pain, or stress notes when clinically relevant

Keep the diary simple enough to complete every morning. Exact precision is less important than consistent estimates.

Sleep Efficiency

Sleep efficiency is calculated as:

total sleep time / time in bed

For example, if a client spent 8 hours in bed and slept 6 hours, sleep efficiency is 75 percent.

In CBT-I, sleep efficiency can help clinicians review sleep consolidation and treatment pacing. It should not be interpreted in isolation. Medical conditions, shift work, medications, pain, trauma symptoms, caregiving, and safety concerns all matter.

How Therapists Review the Diary

A weekly review might ask:

• "What was your average time in bed?"
• "What was your average total sleep time?"
• "Where did sleep latency show up most?"
• "Were awakenings clustered around stress, pain, nightmares, or environment?"
• "How did naps affect nighttime sleep?"
• "What pattern should we test next week?"

The diary should support collaborative hypothesis testing, not shame the client for bad sleep.

Documentation Example

Use the diary to document clinical reasoning:

Therapist reviewed 7-day CBT-I sleep diary. Client reported average time in bed of 8.4 hours, average total sleep time of 5.9 hours, and average sleep efficiency of 70 percent. Diary showed prolonged sleep latency on four nights and late afternoon naps on three days. Therapist provided sleep diary feedback, reviewed stimulus control rationale, and identified one between-session sleep routine adjustment for the coming week.

Avoid treating the diary as a standalone medical conclusion:

Sleep diary proves insomnia diagnosis and determines sleep restriction plan.

Sleep diary data supports clinical review. It does not replace assessment, medical evaluation, or clinician-guided CBT-I decisions.
