CBT-I Patient Assessment & Treatment Planning 2

Question 1

A patient reports spending 9 hours in bed but only sleeping 5 hours. What does this indicate about their sleep efficiency?

Accepted Answer

Sleep efficiency of 56%, below the therapeutic threshold

Answer

Sleep efficiency (SE) = total sleep time / time in bed × 100; 5/9 = 56%, well below the 85% target used in CBT-I.

Question 2

Which validated instrument specifically measures dysfunctional beliefs and attitudes about sleep relevant to CBT-I planning?

Accepted Answer

Dysfunctional Beliefs and Attitudes about Sleep scale (DBAS)

Answer

The DBAS-16 directly assesses maladaptive cognitions about sleep, making it the primary tool for identifying cognitive targets in CBT-I.

Question 3

A new patient presents with chronic insomnia and reports using alcohol nightly to fall asleep. What is the priority assessment step?

Accepted Answer

Evaluate alcohol use disorder severity and its relationship to insomnia onset

Answer

Comorbid alcohol use disorder must be assessed first because alcohol-dependent sleep onset is a contraindication to standard CBT-I sequencing and requires coordinated treatment.

Question 4

When using the ISI to track treatment progress, which score range indicates clinical insomnia in the moderate severity category?

Accepted Answer

15–21

Answer

ISI scores of 15–21 indicate moderately severe clinical insomnia; scores 22–28 indicate severe insomnia.

Question 5

A sleep diary reveals a patient's sleep onset latency (SOL) averages 65 minutes across two weeks. Which CBT-I component most directly targets this finding?

Accepted Answer

Stimulus control therapy

Answer

Stimulus control therapy re-associates the bed with sleepiness by restricting bed use to sleep and sex, directly reducing prolonged SOL.
