Abstract
In the present study, first, I took a general view of the Health-Related Quality of Life. Next, I describe about the HRQOL-20, which the author et al. developed in order to measure a patient's general HRQOL, and suggest that personality type, in terms of the Eysenck Personality Questionnaire, is a possible mediating factor modulating the HRQOL-20 questionnaire responses and the outcome measure, HRQOL.
