What Is the VHI-10?
The Voice Handicap Index-10 (VHI-10) is a 10-item patient self-report instrument that quantifies the functional, physical, and emotional impact of a voice problem from the speaker’s perspective. It was published by Rosen, Lee, Osborne, Zullo, & Murry (2004) in Laryngoscope as the validated short form of the original 30-item Voice Handicap Index developed by Jacobson et al. (1997).
Why patient-reported outcome. Voice problems have measurable acoustic, aerodynamic, and laryngeal correlates — but the same physical findings can produce very different impacts on different speakers. A teacher with mild dysphonia may report severe occupational handicap; an office worker with the same vocal-fold finding may report minimal impact. The VHI-10 quantifies what the speaker actually experiences, not what the laryngoscopic image suggests, and it is the gold-standard patient-reported outcome measure for voice in U.S. voice clinics.
Three domains, ten items. The VHI-10 retains the three-factor structure of the parent VHI-30: Functional (impact on daily activities and communication), Physical (perceived effort and clarity), and Emotional (psychosocial impact). Items were selected for the VHI-10 by retaining the items with the highest item-total correlations from the VHI-30, and subsequent psychometric work has shown equivalent reliability and validity.
Severity bands. The four-band severity classification used in U.S. voice clinics (Arffa et al. 2012; Stemple, Roy, & Klaben 2018) is: Normal / no perceived handicap (0 - 10), Mild (11 - 20), Moderate (21 - 30), Severe (31 - 40). The Arffa et al. (2012) abnormality cutoff of 11 separates the Normal band from the Mild band. The VHI-10 minimal clinically important difference (MCID) has been estimated at 6 - 8 points (Misono, Peterson, & Meredith 2017).
How to Administer the VHI-10
The standard voice clinic procedure for the VHI-10:
1. Baseline at intake. Administer the VHI-10 at the initial voice evaluation alongside the patient interview and before stroboscopic examination. Hand the form to the patient (paper or tablet) and ask them to rate each item based on the past two weeks. Allow 2 - 4 minutes for completion; do not coach the patient on the "correct" answers.
2. Self-report only. The VHI-10 is a patient-reported outcome measure — the score must come from the patient’s perception, not from the clinician’s observation or from a family member’s description. If the patient cannot complete the form independently, use the spouse or proxy version (validated separately) and document the proxy.
3. Score and document. Enter the 10 ratings into this calculator. Document the total, the severity band, the three domain subtotals, and the date in the chart note. The domain subtotals show which area is most affected — a patient with a high Emotional subtotal and a low Functional subtotal needs a different treatment focus than a patient with the opposite pattern.
4. Re-administer at progress milestones. Re-administer the VHI-10 at every major progress milestone — typically every 4 - 6 weeks of voice therapy — and at discharge. Compare the new total to baseline using the MCID of 6 - 8 points (Misono, Peterson, & Meredith 2017): a between-administration change of less than 6 points is within natural variability and should not be reported as a treatment effect. A change of 6 or more points sustained across two administrations is clinically meaningful.
5. Pair with the rest of the voice battery. The VHI-10 quantifies impact; it does not quantify mechanism. Pair with stroboscopic laryngeal examination, CAPE-V perceptual voice rating, an acoustic measure (jitter, shimmer, CPP), and an aerodynamic measure (maximum phonation time, s/z ratio) for a complete intake. The American Academy of Otolaryngology Voice Disorders Quality Improvement Initiative recommends all five.
Arffa et al. (2012) Severity Bands
The four clinical severity bands published in Arffa, Krishna, Gartner-Schmidt, & Rosen (2012) Journal of Voice 26(4):462-465 and standardised in Stemple, Roy, & Klaben "Clinical Voice Pathology" 6th ed. (Plural Publishing, 2018):
Normal / no perceived handicap (0 - 10). Below the Arffa et al. (2012) abnormality cutoff of 11. Within the asymptomatic range for self-perceived voice handicap in the general population. Document the score, reassure the patient, and re-screen if concerns persist or if the speaker is an occupational voice user (teacher, singer, broadcaster, attorney, clergy, fitness instructor) with elevated baseline expectations of vocal performance. Some occupational voice users with VHI-10 scores in the 6 - 10 range still meet the case for therapy because their perceived baseline is higher than the general population norm.
Mild (11 - 20). Meets the Arffa et al. (2012) abnormality cutoff. Occasional self-perceived voice handicap that interferes with selected speaking tasks. Voice therapy is indicated, especially for occupational voice users. Pair with stroboscopic laryngeal examination, CAPE-V perceptual rating, and an aerodynamic measure (MPT or s/z ratio) for a complete intake. Re-administer the VHI-10 at every 4 - 6 weeks of therapy and target a between-administration change of 6 or more points sustained across two administrations.
Moderate (21 - 30). Regular self-perceived voice handicap on most demanding speaking tasks with measurable functional, physical, and emotional impact. Standard voice therapy is indicated. Pair with stroboscopic laryngeal examination and a complete acoustic / aerodynamic battery (CAPE-V, MPT, s/z ratio, jitter / shimmer). Screen for co-occurring globus, dysphagia, and chronic cough — the laryngeal pathology underlying moderate dysphonia often produces overlapping symptoms.
Severe (31 - 40). Pervasive self-perceived voice handicap interfering with most communicative situations across work, social, and personal life. Pursue urgent ENT/laryngology evaluation if not already completed and prioritise voice therapy. Screen for co-occurring depression and anxiety; chronic dysphonia at this severity is associated with elevated psychosocial impact. The treatment plan should include both the medical / surgical workup (laryngology) and the behavioural workup (SLP voice therapy) running in parallel.
Using the VHI-10 in Practice
The VHI-10 is the gold-standard patient-reported outcome measure for voice in U.S. voice clinics, but it is most useful when paired with the rest of the voice battery and tracked across treatment.
At intake. Administer the VHI-10, complete the laryngeal stroboscopy and the CAPE-V perceptual rating, and collect the acoustic / aerodynamic battery (MPT, s/z ratio, jitter, shimmer, CPP). The VHI-10 quantifies how much the voice problem matters to the patient; the rest of the battery quantifies why the voice problem exists. Treatment planning needs both — a high VHI-10 with a normal stroboscopy points to a primarily functional / behavioural voice problem; a low VHI-10 with a clear structural finding may not warrant aggressive intervention if the patient is asymptomatic.
At treatment progress. Re-administer the VHI-10 at every 4 - 6 weeks of voice therapy. Use the MCID of 6 - 8 points (Misono, Peterson, & Meredith 2017) to interpret change: less than 6 points is within natural variability; 6 or more points sustained across two administrations is clinically meaningful. Document the VHI-10 trajectory in the SOAP note alongside the CAPE-V and the acoustic measures so the treatment narrative captures both the patient-reported outcome and the clinician-rated and instrumental outcomes.
At discharge. Re-administer the VHI-10 at the discharge visit and report the change from baseline. For school-age and pediatric voice patients, also re-administer the proxy version completed by the parent if available. The discharge VHI-10 anchors the long-term follow-up plan — patients who discharge with a VHI-10 still in the Mild or Moderate band typically need a maintenance review at 3 - 6 months.
For occupational voice users. Teachers, singers, broadcasters, attorneys, clergy, and fitness instructors typically have elevated baseline expectations of vocal performance and may meet the case for therapy at VHI-10 scores in the 6 - 10 range — below the standard abnormality cutoff. Document the occupational context in the chart and consider treatment even when the VHI-10 is in the Normal band if the patient reports occupational voice failure.
