The main purpose of this study was to assess the mediating role of psychological well-being in the relationship between health-promoting lifestyle and self-efficacy among nurses in Kermanshah province.

The statistical population of this study consisted of nurses from five hospitals in Kermanshah province. A total of 300 people were selected from the nursing community by cluster random sampling. Data collection tools included a general self-efficacy questionnaire, a health-promoting lifestyle questionnaire, and a psychological well-being questionnaire. In order to analyze the data, the causal modeling method was used. This analysis was performed using Emus software.
