This study examined the relationship between moral distress, individual and professional values in oncology nurses.

Employing structural equation modeling, a descriptive-correlational study was conducted among 116 oncology nurses. Data were collected using the Moral Distress Scale-Revised Adult Nurses, the Nursing Professional Values Scale, and the Values Scale.

The mean moral distress frequency was evaluated as low (1.6 ± 0.7) and the intensity as moderate (1.9 ± 0.8). Both the Nursing Professional Values Scale and Values Scale subdimension mean scores were at levels evaluated as high. There was no specific value that stood out from the others. Structural equation modeling analysis showed that individual values were found to have a direct and negative significant effect on moral distress intensity (β = −0.70, p < 0.01) and frequency (β = −0.58, p <0.01) and professional values had a direct positive and significant effect on moral distress intensity (β = 0.37, p < 0.05) and frequency (β = 0.25, p < 0.05).

It is believed that more national and international studies need to be conducted to examine the relationship between the moral distress concept and values. While individual values were found to have a direct and negative significant effect on moral distress, professional values had a direct positive and significant effect on moral distress.
