Description

The Geriatric Oral Health Assessment Index (GOHAI-12) is an internationally recognized self-report psychometric instrument developed to assess oral health and its impact on the quality of life of older adults. Originally developed by Atchison and Dolan (1990), the questionnaire was designed to evaluate not only the clinical condition of the oral cavity but also the extent to which oral health problems affect functional ability, psychological well-being, and everyday activities.

The GOHAI-12 consists of 12 items that assess functional limitations, pain or discomfort, and the psychosocial consequences of oral health conditions. It is widely used in dentistry, geriatric medicine, public health, and epidemiological research, and is considered one of the most reliable instruments for measuring Oral Health-Related Quality of Life (OHRQoL) among older populations.

Purpose

The primary purpose of the GOHAI-12 is to evaluate older adults’ perceived oral health status and to examine how oral health affects daily functioning, nutrition, communication, social participation, and overall quality of life.

In addition, the instrument is used to:

  • Identify oral healthcare needs.
  • Evaluate the effectiveness of dental treatments and preventive interventions.
  • Monitor changes in oral health status over time.
  • Investigate the relationship between oral health and general health.
  • Support public health programs aimed at promoting oral health among older adults.

Data Analysis and Interpretation

The GOHAI-12 evaluates three major dimensions of oral health:

  • Functional dimension, including chewing, swallowing, speaking, and the ability to eat a variety of foods.
  • Pain and discomfort, including oral pain, sensitivity, and discomfort experienced during daily activities.
  • Psychosocial dimension, assessing the impact of oral health on self-confidence, social interactions, self-image, and overall psychological well-being.

Overall and domain-specific scores can be analyzed in relation to important variables such as:

  • Quality of life
  • Functional independence
  • Nutritional status
  • General health status
  • Cognitive functioning
  • Depression and anxiety
  • Frailty
  • Need for dental or prosthetic treatment

The GOHAI-12 is extensively used in clinical studies, epidemiological research, geriatric assessments, and public health programs focusing on the promotion of oral health and healthy aging.

Scoring

The questionnaire is typically scored using a five-point Likert scale, with each item receiving a score ranging from 1 to 5. Depending on the wording of individual items, some responses require reverse scoring to ensure a consistent interpretation of the total score.

The overall score ranges from 12 to 60, with higher scores indicating better perceived oral health, fewer functional limitations, and a higher oral health-related quality of life. Conversely, lower scores reflect greater oral discomfort, increased functional impairment, and a more substantial negative impact of oral health problems on daily living.
