Quality of life (QOL) refers to an individual's perception of their overall life and well-being. As people age, their QOL often deteriorates. Although various outcome measures exist to assess QOL, most are limited in scope and not specific to the Indian ethnicity of geriatrics. Therefore, a new outcome measure was developed and validated to more accurately evaluate the QOL for the geriatric population in India. The outcome measure was developed in three stages, followed by validation. Data was collected using multistage cluster sampling from 13 subdivisions of Jaipur district. A total of 423 participants were interviewed face-to-face. The collected data was analyzed using SPSS version 20, and the reliability and validity of the outcome measure were assessed. The Indian Geriatrics Quality of Life Inventory (IGQOL) scale demonstrated excellent reliability, with a Cronbach's alpha (α) of 0.95 and an intraclass correlation coefficient of 0.93. The measure also exhibited excellent face and content validity, with a K value of 1. Correlation analysis revealed a significant relationship with other outcome measures, with a Pearson correlation coefficient value of > 7 and a p-value of < 0.05. The study concludes that the IGQOLI scale is a reliable and valid outcome measure for evaluating the QOL in the geriatric population in India.
