Understanding the Voice Handicap Index (VHI)
What is the Voice Handicap Index?
The Voice Handicap Index (VHI) is a patient-reported outcome measure developed to quantify the emotional, functional, and physical impacts of voice disorders. It provides valuable insights into how a voice disorder affects an individual's daily life, self-esteem, and social interactions.
Initially developed by Jacobson et al. in 1997, the VHI has become a standard tool used globally for:
- Assessing baseline voice issues
- Monitoring treatment progress
- Evaluating the effectiveness of interventions
Components of the VHI
The VHI comprises three subscales, each addressing different aspects of voice-related handicap:
- Functional (F): How the voice disorder affects daily activities such as speaking on the phone, singing, or whispering.
- Emotional (E): The emotional reactions and feelings related to having a voice disorder, including frustration, embarrassment, or depression.
- Physical (P): The physical sensations or symptoms experienced, such as throat pain, dryness, or vocal fatigue.
Each subscale contains a series of statements rated by the patient on a Likert scale, typically from 0 (never) to 4 (always), culminating in a total score that reflects the overall voice handicap severity.

Implementing the Voice Handicap Index PDF in Practice
Preparation Before Administration
Prior to administering the VHI PDF:
- Ensure that the patient understands the purpose of the questionnaire.
- Clarify any terminology or instructions.
- Decide whether the form will be filled out electronically or on paper.
Administering the VHI PDF
Steps to effectively administer the VHI:
- Provide the PDF form to the patient, either printed or via a digital device.
- Allow sufficient time for the patient to complete the questionnaire without feeling rushed.
- Review the responses for completeness and clarity.
- Discuss the results with the patient to understand their perspective and concerns.
Scoring and Interpretation
The VHI scoring process involves:
- Summing responses within each subscale.
- Calculating the total score (sum of all subscales).
- Interpreting scores based on established thresholds:
- Normal voice: lower scores
- Moderate to severe handicap: higher scores
Clinicians can use scoring sheets or digital tools to streamline this process.
Documenting and Tracking Progress
The PDF can serve as a baseline measure, with subsequent administrations to monitor:
- Improvement after therapy
- Changes post-surgery
- Impact of interventions over time
Maintaining a record of scores in the patient's file or EHR is vital for comprehensive care.
