Development, reliability, and validity of a Japanese version of the Professional Quality of Life Scale for Nurses

Abstract

In this study, we developed a Japanese version of the Professional Quality of Life Scale for Nurses (ProQOL-JN). The scale was designed to evaluate the quality of life of people working as health care professionals and involves three subscales: compassion fatigue/secondary traumatic stress, compassion satisfaction, and burnout. The scale's reliability and validity were examined using data from 618 Japanese nurses. The results indicated that this scale had three component structures; furthermore, a test-retest correlation and an internal consistency indicated that the scale had high reliability. Correlations with the Impact of Event Scale-Revised, the Japanese version of the Posttraumatic Growth Inventory, and the Japanese version of the Burnout Inventory were mostly consistent with the current theory of professional quality of life, which supports the high validity of the ProQOL-JN. These results indicated that the scale has the required reliability and validity to measure nurses' quality of life.
