The Indian Geriatrics Quality of Life Inventory Scale (IGQOLI): Development and Validation of a Scale to Evaluate the Quality of Life among Geriatric Population of India.

Background: 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. Methods: 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. Results: 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. Conclusion: The study concludes that the IGQOLI scale is a reliable and valid outcome measure for evaluating the QOL in the geriatric population in India.
