Associations of Health-Related Quality of Life with Overall Quality of Life in the Patient Reported Outcomes Measurement Information System (PROMIS®) Project

Health-Related Quality of Life (HRQOL) and evaluative well-being (EWB) surveys are used at local and national level to monitor population health. Significant associations have been reported between HRQOL and EWB measures. Perceptions of overall quality of life are one type of EWB measure. This study estimates associations between a quality of life item and HRQOL items in two datasets (n = 21,133 and n = 2996) collected as part of the U.S. Patient Reported Outcomes Measurement Information System (PROMIS®) project. HRQOL measures accounted for 69% to 75% of variance in overall quality of life. The study provides further evidence about the empirical overlap between EWB and HRQOL. EWB researchers need to explicitly incorporate HRQOL measures and vice versa in their research. Future research is needed to determine the extent to which the associations between EWB and HRQOL vary by individual characteristics.
