Background and Objectives: Compassion has been identified as an essential element of nursing. The present study aimed to determine the psychometric properties of compassion to others scale and introduce a suitable measurement scale for the researchers in the field of psychological health. Methods: This study was conducted on a total of 213 nurses in order to investigate the psychometric properties of compassion to others scale based on multistage sampling method. The data were analyzed using LISREL (version 8) and SSPS (version 18) software. Results: The factor structure of compassion to others scale was confirmed according to the results of Confirmatory Factor Analysis in Iranian nurses. Compassion to others scale had a negative and significant correlation with the fear of compassion, anxiety, depression, and stress, burnout, as well as unhealthy cognitive emotion regulation skills, and also a positive and significant correlation with healthy cognitive emotion regulation skills (P<0. 05). Furthermore, Cronbach’ s alpha coefficient, for the whole scale and factors, including kindness, indifference, common humanity, separation, mindfulness, and disengagement, were obtained as 0. 92, 0. 81, 0. 61, 0. 83, 0. 78, 0. 78, and 0. 76, respectively. Conclusion: In this study, the psychometric properties of Iranian version of compassion to others scale were confirmed. Therefore, this scale was proposed to measure the level of compassion to others in nurses.
