CBT for Insomnia (CBT-I) for Tinnitus: What Does the Evidence Show?

Current evidence

Tinnitus keeps you awake; insomnia makes tinnitus worse. Treating the insomnia breaks the loop.

Evidence strength: Moderate (3/5) · Tier 2 — promising · Evidence independence: Primarily independent.

A structured insomnia therapy (sleep restriction, stimulus control, cognitive work) adapted for tinnitus-related insomnia. Sleep disturbance affects most people with bothersome tinnitus — estimates commonly exceed 40%.

Did tinnitus loudness improve?

None shown. No loudness effect claimed.

Did tinnitus distress improve?

Moderate. RCT (N=102): clinically meaningful insomnia improvement in >80% with CBT-I vs 47% (audiology care) and 20% (support group); tinnitus distress (a secondary outcome) also improved, sustained at 6 months.

Loudness means the tinnitus percept itself became quieter (psychoacoustic matching or loudness ratings). Distress means questionnaire scores such as THI/TFI, sleep, anxiety or quality of life improved — the sound may be unchanged. A THI/TFI improvement is never evidence the tinnitus got quieter.

How strong is the evidence?

One well-run RCT with sustained effects earns 3/5; multicenter replication would raise it.

Has the result been independently replicated?

None yet. Single positive RCT (Marks 2023); no replication attempt yet.

What are the limitations?

• Single-center trial
• Tinnitus outcomes were secondary
• Requires real behavioral commitment for several weeks

What should patients know about safety?

Safety evidence: Strong. Safe; temporary daytime sleepiness during sleep restriction.

Is it available?

Regulatory status: Standard psychological therapy. CBT-I is first-line treatment for chronic insomnia generally.

Availability: Sleep clinics and digital CBT-I programs · Europe: Available · Cost (approx.): $100–250/session or app-based from ~$50
