CBT-I Treatment Outcomes & Research Evidence Flashcards

Which organizations have endorsed CBT-I as the first-line treatment for chronic insomnia in adults?

Answer: American Academy of Sleep Medicine (AASM) and American College of Physicians (ACP)

Both the AASM and the ACP have issued clinical practice guidelines recommending CBT-I as the first-line treatment for chronic insomnia.

Compared to sleep medication, CBT-I demonstrates:

Answer: Similar short-term and superior long-term effects with maintained gains after treatment ends

CBT-I produces comparable short-term effects and superior long-term outcomes because gains persist after treatment ends, unlike medication effects that diminish when discontinued.

The typical response rate for CBT-I in randomized controlled trials is approximately:

Answer: 70-80%

Meta-analyses consistently show 70-80% of patients achieve clinically meaningful improvements with CBT-I.

The Insomnia Severity Index (ISI) clinical response is defined as a reduction of at least how many points?

Answer: 6 points

A reduction of 6 or more points on the ISI is the accepted threshold for clinically meaningful response in insomnia treatment research.

Which component of CBT-I has the strongest evidence base as a standalone intervention?

Answer: Stimulus control therapy

Stimulus control therapy has the most robust evidence as a single-component intervention, with decades of research demonstrating its efficacy.

Sleep diary data used in CBT-I outcome measurement primarily tracks which variables?

Answer: Sleep efficiency, total sleep time, and sleep onset latency

Sleep diary captures subjective measures of sleep efficiency, TST, SOL, and WASO, which are the primary CBT-I outcome variables.
