Abstract: Objective To understand the current situation of perceived decent work,psychological capital,and occupational burnout among oncology nurses of grade-A tertiary comprehensive hospitals in Guangzhou,and to explore the mediating role of psychological capital between the perception of decent work and job burnout. Methods From January to March 2024,a purposive sampling method was used to investigate 178 oncology nurses from six grade-A tertiary comprehensive hospitals in Guangzhou City using the decent work perception scale,psychological capital scale and occupational burnout scale,and the data were analyzed. Results The scores of decent work perception,psychological capital,and job burnout of oncology nurses were （52.48±11.32）,（91.12±15.84） and （62.24±12.52）points,respectively. There were statistically significant differences in the decent work perception scores among oncology nurses with different age,professional title,years of work experience,average monthly total income,average monthly night shifts,and marital status（all P<0.05）. There were statistically significant differences in the psychological capital scores among oncology nurses with different age,professional title,years of work experience,average monthly total income,and marital status（all P<0.05）. There were statistically significant differences in the job burnout scores among oncology nurses with different gender,age,professional title,years of work experience,average monthly total income,average monthly night shifts and marital status（all P<0.05）. The higher the score of decent work perception of oncology nurses,the lower their level of job burnout（r=-0.536,P<0.01）. The higher the score of psychological capital of oncology nurses,the lower their level of job burnout（r=-0.612, P<0.01）. The higher the score of decent work perception of oncology nurses,the higher their level of psychological capital（r=0.528,P<0.01）. Psychological capital played a mediating role between decent work perception and job burnout among oncology nurses,and the mediating effect value was -0.240,accounting for 41.24% of the total effect. Conclusion The perception of decent work,psychological capital,and occupational burnout among oncology nurses in six grade-A tertiary comprehensive hospitals in Guangzhou are all at a high level. The psychological capital of oncology nurses plays a partial mediating role between the perception of decent work and occupational burnout. Improving the psychological capital of oncology nurses can enhance their perception of decent work and further reduce the level of occupational burnout.
