Rajendra Jinjwaria quality of life-22 scale (RJQOL-22) scale

Abstract

The Rajendra Jinjwaria quality of life-22 (RJQOL-22) scale will help assess the overall quality of life in various acute and chronic diseases such as rheumatoid arthritis, osteo arthritis, and other conditions that affect the quality of life such as cardiovascular, HIV, and cancer. The tool was developed from 29 January 2019 to 01 May 2023 by Rajendra Kumar Jinjwaria at King George's Medical University Lucknow and Banaras Hindu University, Uttar Pradesh, India. The validity of the RJQOL-22 scale was established as per the content validity index (CVI) 98% and validated by more than 100 expert faculty across the world. The scale is standardized and highly valid for assessing the quality of life in acute and chronic diseases. The overall reliability of the scale based on a study was estimated to be (>0.983) through (Cronbach’s alpha value) and it indicates a highly reliable scale. While the individual reliability of group I and group II was 0.989 and 0.978 respectively. The acceptable cut-off value of coefficients was 0.7 for moderate and 0.8 for high reliability. This indicates that the tool used in the studies was highly reliable.
