Abstract
OBJECTIVE: The Significant Quality of Life Measure (SigQOLM) is a validated scale used to measure a broad spectrum of quality of life and well-being. Given that the original SigQOLM consists of 69 items, this study aims to revise and validate a shortened version, referred to as SigQOLM-36, containing 36 items. RESULTS: The overall internal consistency of SigQOLM-36 was deemed excellent, with a Cronbach's alpha coefficient of 0.923. The minimum Cronbach's alpha coefficient for each domain was 0.733, McDonald's omega coefficients ranged between 0.562 and 0.991, and with a minimum factor loading of 0.547. Additionally, the model fit for the overall framework and each domain of SigQOLM-36 was found to be excellent (Chi-square test < 0.30, RMSEA < 0.80, SRMR < 0.08, CFI > 0.9, and TLI > 0.9). The SigQOLM-36 maintains the original SigQOLM framework, featuring four elements and 18 domains. In conclusion, the SigQOLM-36 can be used to measure quality of life and well-being of people.
