Our study showed a significant relationship between ProQOL and GHQ dimensions, so reducing burnout and secondary traumatic stress as well as increasing compassion satisfaction has a direct impact on decreasing mental health problems in staff. Compassion satisfaction has a negative relationship with physical dysfunction, anxiety and sleep disorders, social dysfunction and severe depression. Burnout and secondary traumatic stress have a positive relation with these health-related factors. Gender, marital status and education do not affect the professional quality of life and general health, yet emergency department personnel compared to other sectors experience more depression and traumatic stress.
The positive associations between burnout and four of the subscales that were measured by the GHQ (somatic symptoms, anxiety, distress, and social dysfunction) are consistent with the findings of Musa et al. (
19). Furthermore, Kasraie et al. (
20) showed that there is an inverse correlation between job stress and quality of work life, where quality of life decreases by increasing staff stress. Also, this study showed a significant relationship between job stress, job satisfaction, quality of work life and citizenship. The study of Wu et al. between job burnout and occupational stress was proved and they concluded that reduction in occupational stress could lead to burnout prevention (
21). This conclusion is consistent with the findings of Conrad and Kellar-Guenther, who reported that burnout could result from extreme job stress, thus controlling psychological stress can help mitigate burnout. Moreover, the negative association between sympathy satisfaction (job satisfaction) and burnout were supported by this research (
22).
Another study (
23) showed that burnout is common in nurses. The main causes of burnout are staff crisis in hospitals and work overload. This study suggests that nurses need special attention in Iran. Many nursing staff remain at their positions for only a few months around the world. Study of Hsu showed that the development of a questionnaire is reliable and valid for examining the quality of working life of nurses (
24).
Mohammadi et al. (
12) studied the relationship of nurse’s psychological problems and quality of work life (QWL) in the intensive care unit of Tehran hospitals, in 2010. The study showed that it is necessary to consider the anxiety of nurses, especially by directors due to the impact of anxiety on reduction of nurses’ QWL. Soric et al. (
25) stated that there is no evidence of a significant association between quality of life and work ability yet showed that education has a positive association with work ability of nurses and their quality of life. In another study in China, burnout and two dimensions of occupational adjustment were measure in nurses (occupational stress and coping resources). This study showed that it is better to do job redesigning and offering occupational health education to reduce occupational stress and to prevent burnout (
21).
The subscales of professional quality-of-life were not related to the position type of the employee, age, or gender. Employees, who were leaving their position showed higher burnout and lower compassion satisfaction scores (
26). Berceli et al. showed that chronic stress has a negative effect on the health-related quality of life (
27).
Study of Kasraie et al. (
20) showed relationships between hospital job stress, job satisfaction, quality of work life, and citizenship behavior.
Musa et al. (
19) examined the relationships between quality of work life subscales including job satisfaction or compassion satisfaction, compassion fatigue or secondary traumatic stress, burnout, and distress. In this study, three instruments were used to measure the target relations and they concluded that there is a need to create a positive work climate through equipping aid workers with adequate training, psychological support services and cultural orientation to decrease the psychological suffering of aid workers. In a study by Khaghanizadeh et al. nurses were selected via probable multistage sampling. They explained that the nurses with high QWL tended to have lower job stress (
15).
Therefore, authorities in the health care system should develop strategies and intervention programs toward improving the three attributes, which will lead to improving the quality of staff's working life, increasing the quality of patient care, and saving health-care organizations.
This study had some limitations including lack of good cooperation of some staff to fill the questionnaires, the study population being selected from only one hospital and low number of target population.
In addition, the analysis suggested that it may be useful to investigate the effective factors on ProQOL and GHQ dimensions, which will help managers apply better policies in order to increase their staff performance.
