Results showed a positive and significant relationship between total CT disposition and empathy tools and their components (except for the systematicity and maturity with standing in the patient's shoes, and the truth-seeking with compassionate care components). Gunaydin and Unsal Barlas showed a positive and significant relationship between the total CT score and the disposition toward empathy (
22), which is consistent with the results of the present study, however, there was no significant relationship between the CT components with the disposition toward empathy, which is inconsistent with the results of the present study. This discrepancy can be due to differences in the individual characteristics, research population, and so on. In addition, the results of the study by Jeong showed a positive and significant relationship between CT and disposition to empathy (
23), which is consistent with the results of the present study. Mousazadeh et al. (
24), showed that CT disposition level in nursing students is higher than average. In addition, the results of the study by Wangensteen et al. (
25), showed that the mean CT disposition is at a moderate level, which is consistent with the results of the present study. Vafadar et al. (
8), showed that the level of empathy of nurses working in the armed forces was at a moderate level. Khodabakhsh also showed a moderate empathy level among nursing students (
26), which is consistent with the results of the present study. The relationship between CT and empathy may not be obvious. It may even seem contradictory; however, CT leads to the maturity, inquisitiveness, analysis, and evaluation of multiple perspectives in a complex problem (
22). On the other hand, empathy is one of the basic needs for identifying patients' problems. Interpersonal empathy is significantly effective in achieving and maintaining positive health behaviors (
27) and higher empathetic ability of helping individuals achieve a better understanding and paying more respect to other cultures (
28). In nursing, CT is an essential element for nurses. In this regard, one of the characteristics of nurses with CT potential is to have appropriate interpersonal communication skills. In this regard, Shahjooi et al. (
29), concluded that there was a significant relationship between the CT disposition and interpersonal communication skills. In addition, the results of the study by Kim and Han showed a significant relationship between the CT disposition and interpersonal communication skills among college students (
30). Similarly, Kang et al. (
31), stated that the goal of nursing education is to ensure creativity and critical thinking skills and nurses are expected to solve the patients' health problems through scientific problem-solving methods and acquisition of knowledge, attitudes, and necessary skills after the end of the training period. Nursing, as a stressful occupation, is always faced with serious challenges. Characteristics such as having hope in the face of failures and the belief in the solvability of all problems, as well as trust in personal abilities will help lead nurses to take advantage of positive outcomes of the issues and create a positive perspective on the problems. The positive effect of the above personal characteristics can be seen in nurses' empathetic ability (
15). An empathetic person understands the needs and demands of other individuals in various ways, such as verbal and nonverbal behaviors, and tries to understand their emotions and feelings (
5). The results showed that the mean empathy score in female nurses was significantly higher than males, however, the mean CT score in nurses was not significant in terms of gender. In a study, Alkan concluded that empathy in female nurses was higher than males (
32), which was consistent with the results of our study. In addition, studies carried out by Ward et al., at Thomas Jefferson University (
2), and Williams et al. (
33), were consistent with the present study with regards to the mean empathy score in female nurses. According to Asadi et al.'s study, men show better disposition toward CT than women, which is not consistent with the results of the present research, however, there is no specific relationship between age and level of education with CT, which is consistent with the results of the present study (
34). There was also no significant difference between mean CT, empathy scores, and age variable. Vafadar et al. (
8), concluded that the mean empathy score in nurses was not significant in terms of gender and age, which is consistent with the results of the present study. Mousazadeh et al. (
24), and Hunter et al. (
35), concluded that the subjects' mean CT score was not significant in terms of gender.
In addition, the results of various studies showed no significant relationship between CT and age (
25,
36), which is consistent with the results of the present study. However, increasing age and experience are expected to lead individuals to show more CT dispositions and empathy, and thus, use this skill more frequently. However, such results were not obtained in the present study, which may be attributed to the crowded work environment, lack of training in these skills, older personnel, and cultural differences. Adams et al. (
37), also showed that the nursing CT level increases with increasing work experience, which is inconsistent with the results of the current study. The results of Gunaydin and Unsal Barlas study showed a significant relationship between gender and age with CT. In addition, a significant relationship was found between age and empathy (
22), which is inconsistent with the results of the present study. The results of Petrucci et al.'s study showed no significant relationship between disposition to empathy and age group (P > 0.05), which is consistent with the results of this study (
38).
