This study aimed to conduct a short- and long-term Compassion Fatigue Resiliency Program and compare its impact on nurses' professional quality of life, perceived stress and resilience. The research was conducted between January 2017 and January 2019 as a randomized controlled trial. The sample comprised 125 oncology-hematology nurses randomly assigned to a Experimental I (short-term Compassion Fatigue Resiliency Program), Experimental II (long-term Compassion Fatigue Resiliency Program) or control group. Data was collected using Personal Information Form, Professional Quality of Life Scale-IV (ProQOL-IV), Perceived Stress Scale, and Resilience Scale for Adults. Measurements were obtained during pre- and post-test and at three-, six- and twelve-month follow-ups. Research hypotheses were analyzed using multilevel models.

The research was conducted with nurses from the oncology-hematology inpatient services, outpatient chemotherapy units and bone marrow transplant (BMT) units of three private hospitals in Istanbul between January 2017 and January 2019. No sample selection models were applied, and out of 153 nurses working in these services, 125 nurses meeting the inclusion criteria were included in the study. Nurses were randomly assigned to the Experimental I, Experimental II, or control group in order to prevent interaction between the subjects working in the same hospital. Of the nurses, 34 completed the short-term program (Experimental I), 49 completed the long-term (Experimental II), and 42 were assigned to the control group.

Data collection: Data was collected using Personal Information Form, Professional Quality of Life Scale-IV (ProQOL-IV), Perceived Stress Scale, and Resilience Scale for Adults Study procedure This study's principal investigator had participated online in a CFRP, developed by Eric Gentry (Licensed Mental Health Counselor) (2002), and received the certificate, and then conducted the program with the nurses. Meetings were held with each institution's directorate of nursing services to determine the training schedules and content. The schedules were planned in accordance with the hospital administration's preferences and by taking nurses' busy schedules into consideration. Preliminary tests were applied to Experimental I, Experiment II, and the control group before the training. Experimental I received a short-term program (five hours per day for two days, ten hours in total) while Experimental II received a long-term one (five weeks, two hours per week, ten hours in total). No intervention was applied to the control group. After the training, a post-test, and three-, six-, and twelve-month follow-up assessments were conducted for all groups.

Program Compassion Fatigue Resiliency Program The purpose of the program: The purpose of the program is to provide oncology-hematology nurses with knowledge and skills that will increase their level of resilience by helping them recognize compassion fatigue, cope with its consequences and work effectively.

The objectives of the training program

Nurses, who successfully complete the program will be able to:

• Explain the historical development of compassion fatigue among caregivers,
• Define the developmental process of compassion fatigue,
• Specify the risk factors for compassion fatigue,
• Explain the symptoms of compassion fatigue,
• Raise awareness about their personal history,
• Explain the concept of stress and its impact on the body,
• Apply compassion fatigue resilience skills acquired in the program,
• Professionally create a self-directed resilience plan. Validity and reliability/Rigour The included scales have been tested for validity and reliability for various settings and countries. The investigators chose three private hospitals in Istanbul, which are considered to be close to each other, such as institution (etc. working conditions) and the sociodemographic and professional characteristics of nurses (etc. age, educational status, clinical experience, willingness to work in oncology, voluntarily career choice) that are known to affect dependent variables. Then, the investigators randomly assigned each hospital to the Experimental I, Experimental II, or control group in order to prevent interaction between the nurses working in the same hospital. Finally, the program was conducted by the principal investigator who had participated online in a CFRP, and received the certificate.

Data analysis: SPSS 25.0 software package was used to analyze data. A chi-square test and one-way ANOVA determined whether the scales and information on demographic characteristics and work environment differed among pre-initiative groups; in other words, to measure homogeneity. Variables found to be statistically significant were included in the model as a correction factor for primary hypotheses. Primary research hypotheses were analyzed using multilevel models (MLM). This analysis method has some advantages over others, such as repeated measures ANOVA.

Inclusion criteria

• Nurses working in inpatient oncology-hematology, outpatient chemotherapy, or BMT unit Exclusion criteria
• Providing care for pediatric oncology patients
• Being a nurse manager
• Not providing direct patient care

No, because hospitals told us, the investigators have to keep secret their nurses individual data.
