Tinnitus Handicap Inventory
Also known as: THI
The Tinnitus Handicap Inventory (THI) is a 25-item self-report scale that quantifies the functional, emotional, and catastrophic effects of tinnitus on daily life, work, and psychosocial well-being. Developed by Newman, Jacobson, and Spitzer in 1996, it has become the gold-standard outcome measure for assessing tinnitus-related handicap in clinical practice and research. The THI enables clinicians to track disease burden, monitor therapeutic response, and identify patients at risk for severe psychological distress.

When to use it
The THI is indicated for all patients presenting with tinnitus, including those with age-related hearing loss, occupational noise exposure, ototoxic medication effects, and idiopathic tinnitus. It is essential in otolaryngology, audiology, and neurotology clinics. Valuable for baseline assessment, monitoring response to sound therapy or cognitive-behavioral intervention, and selecting candidates for advanced treatments (intratympanic steroid injection, transcranial magnetic stimulation). Also used in research evaluating new tinnitus therapies.
Strengths & limitations
- Excellent reliability (test-retest intraclass correlation coefficient = 0.92) and internal consistency (Cronbach's α = 0.93)
- Multidimensional assessment distinguishing functional, emotional, and catastrophic domains of tinnitus handicap
- Extensively validated across age groups, hearing status, and tinnitus etiologies (sudden sensorineural hearing loss, noise exposure, Ménière disease, idiopathic)
- Strong prognostic validity: THI scores predict benefit from sound therapy and cognitive-behavioral therapy
- Identifies patients at risk for mood disorder and suicidality; scores >58 warrant mental health referral
- Omnibus 25-item scale does not distinguish primary tinnitus perception from secondary anxiety/depression; high catastrophic subscale may reflect mood disorder
- Assumes tinnitus severity relates to loudness and pitch; does not measure acoustic characteristics (frequency, loudness level in decibels)
- Limited evidence in pediatric populations; primary validation in adults aged 18–70 years
- Does not assess tinnitus-related sleep disruption directly; sleep loss effects captured only indirectly through functional items
Frequently asked
What is the minimal clinically important difference (MCID) for the THI?
The MCID is approximately 20 points. This represents meaningful clinical improvement or deterioration. A change of 20 points or greater indicates significant treatment effect on patient-reported tinnitus handicap.
Can THI be used to diagnose tinnitus or predict audiometric findings?
No. The THI measures handicap (patient-perceived impact), not tinnitus presence or severity. Audiometry is required to assess hearing loss and acoustic characteristics of tinnitus. THI and audiometry provide complementary information: one may have normal hearing and severe THI (or vice versa), indicating that perception and emotional response drive disability, not objective sound level.
How does THI compare to other tinnitus measures?
The THI (25 items) is briefer than the Tinnitus Functional Index (25 items, 0–100 scale; broader scope), Tinnitus Handicap Questionnaire (27 items; similar content), and simpler single-item Visual Analog Scales (less robust). The THI remains the most widely used and researched measure in audiology and otolaryngology.
Is a high THI score associated with suicidality or psychiatric emergency?
Yes, THI scores >60 (especially >78) are associated with significant emotional distress, depression, and suicidal ideation. When THI is catastrophic (>78) or when catastrophic subscale is markedly elevated, concurrent screening with PHQ-9 (depression), GAD-7 (anxiety), and C-SSRS (suicidality) is essential. Immediate psychiatric referral is recommended if suicidal ideation is present.
