In this study, it is stated that six of the identified items have semantic similarity with the original items and only the dimension of justice was identified as a new dimension in this study. To determine experts’ attitude towards different dimensions of medical science professionalism, the components of the evaluation of attitude towards professionalism were reviewed and completed with the help of a survey method. According to research’s experts, the initial components of a questionnaire designed at the University of Pennsylvania, which included the dimension of accountability, enrichment, equity, respect and originality, altruism, duty and respect, were surveyed in the two rounds of surveying, they changed to the components of responsibility, enrichment, justice, honor and honesty, altruism, duty and respect. The initial number of indicators of the questionnaire included 36 indicators, which after 2 rounds of surveying we identified 48 indicators. The results of Blackall et al.'s (2007) study showed that the Penn College of Medicine Professionalism Questionnaire was one of the first valid and reliable surveys to examine attitudes among medical students, assistants, and faculty that have seven professional elements (altruism, accountability, enrichment, duty, equity, honor and honesty, and respect for others). In this study, among the initial dimension designed at the University of Pennsylvania, the components of excellence were switched to enrichment, fairness to equity, respect, and nobility changed to honor and honesty, while in Blackall et al.'s (2007) study, only one new component. equity has been added to the basic professionalism dimensions of the American Board of Internal Medicine, which included altruism, accountability, enrichment, duty, honor and honesty, and respect for others. In order to determine clinical professors’ attitudes towards the dimensions of medical professionalism in the professionalism evaluation instrument with the help of a survey, the results of one-sample t-test showed that the variable of professionalism and all its dimensions were in good condition. Attitudes of clinical professors towards the dimensions of medical science professionalism were assessed using a questionnaire obtained from a survey of expert professors by an online questionnaire and the average opinions of clinical professors were compared with a fixed number (median range of the questionnaire), If there is a large and significant difference with the median (above 3), it indicates a high score given by clinical professors in that dimension. The average of professionalism dimension according to clinical professors, showed that the highest value was given to the dimension of honor and honesty with an average of 4.4 and other dimensions, including respect, accountability, equity, duty, enrichment and altruism respectively with averages of 4.38, 4.25, 4.2, 3.98, 3.93 and 3.91 Joshua Jauregui 's (2016) study entitled Emergency Medicine Resident Perceptions of Medical Professionalism showed that the lowest score is in altruism and duty and service and the highest in respect for others (7). However, in the current study, the dimension of honor and honesty has the highest average rank and the dimension of respect has the second highest rank, which is different from the results of Jauregui (2016) in terms of ranking, also the dimension of altruism in the ranked last similar to the results of Jauregui’s (2016) research A 2007 study by Campbell et al. On 3,504 physicians specializing in six disciplines, including cardiovascular disease, surgery, anesthesia, pediatrics, internal medicine, and family physicians, found that the highest average was given to the honesty dimension. (8) In the current study, the highest mean was related to the component of honor and honesty, which is similar to the results of Campbell et al. (2007). Research of agha Mohammadi et al. (2017) by examining the attitudes of clinical faculty physicians towards professionalism, found that the professional attitude of medical professors in the indicators of enrichment, honor and honesty and respect are at the highest level and in the indicators related to altruism and duty are at the lowest level (9). However, in the current study, the dimension of enrichment has the lowest rank, so Agha Mohammadi et al. (2019) ‘s findings in the case of the lowest ranked dimension are different to the results of the current study. Also in the current study, the component of honor and honesty is ranked first, but in the study of Mohammadi et al. (2019) the component of enrichment is in the first rank and honor is in the second rank, which is relatively similar to the findings of this study. According to these findings, clinical professors have more patient care responsibilities, as a result of increasing responsibility, patient management is inversely related to enrichment and altruism and is directly related to the degree of honor and honesty. In general, education and models for medical professionalism should be formed with more emphasis on the subject of honor and honesty. In order to determine the position of dimensions of medical professionalism in the professionalism evaluation instrument with the help of factor analysis and expert group, the results showed that the enrichment dimension with a factor load of 0.238 has the highest ability to measure the professionalism variable. In the next ranks, respectively we have, the dimensions of respect, accountability, altruism, duty, honor and honesty and equity, respectively, with a factor of 0.215, 0.212, 0.163, 0.146, 0.106 and 0.047. It should be noted that the factor load index indicates the the sub-factor ‘s ability to measure the variable and its range is between 0 and 1, so the closer to the number one, the higher the sub-factor ability to measure the variable. Findings of this goal showed that none of the questions of the initial questionnaire needed to be removed and the initial model was acceptable and approved. On the other hand, the fit indices of the model were all within an acceptable range and confirmed the fit and standardization of the model, it should be noted, that because surveying the experts, the proposed reforms were done in several stages, the fit was good in this stage. The results of Agha Mohammadi et al. (2017) showed that the professional attitude of medical professors in the indicators of enrichment, honor and honesty and respect are at the highest level and respectively in the indicators related to altruism and duty are at the lowest level (9). In the aforementioned study dimension of enrichment was in the first rank and also in the current study, the dimension of enrichment is similarly in the first rank. However, the dimension of equity in this has the lowest rank, but in the research by Mohammadi et al., The duty dimension had the lowest factor load, Therefore, in the first rank dimension (enrichment), the findings of this research and the aforementioned research are similar, but in the last ranked dimension, they are different from each other. The results of Jauregui’s (2016) study entitled emergency medical residents’ perception professionalism showed that the lowest score is in altruism and duty and service and the highest is in respect for others (7). While in this research, respect for others is in the second rank and altruism and duty are in the fourth and fifth ranks, and the last rank is assigned to the dimension of equity. Therefore, the findings of this study are different from Jauregui’s research in terms of dimension ranking. A 2007 study by Campbell et al. On 3,504 physicians specializing in six disciplines, including cardiovascular disease, surgery, anesthesia, pediatrics, internal medicine, and family physicians, showed that the highest average was related to the honesty dimension. (8) However, in the current study, the dimension of honor and honesty is in the last ranks, so the findings of the study of Campbell et al. (2007) are different from the results of the current study in terms of dimension ranking. The findings of this study can help to localize and validate the instruments for assessing attitudes toward professionalism based on the opinions of clinical professors of Iranian universities of medical sciences and to expand our knowledge in this field. The results of the current study can also pave the way for newer research to expand upon the knowledge of evaluating professionalism based on the views of clinical professors. At the practical level, the findings of this study can be used to develop educational programs and interventions in relevant organizations to promote professional attitudes, and clinical counselors and psychologists can also use the results of this study in the same sense. According to the results of this study and the opinions of clinical professors and experts of Iranian universities of medical sciences, it is necessary to study Localization and validation of a survey instrument to assess attitudes toward professionalism based on the opinions of clinical professors of Iranian universities of medical sciences. According to the applied results of this study, it is suggested that in the next research, the attitudes of clinical professors towards professionalism in different fields and specialties as well as in different cities and ethnicities be studied and compared. The same research on larger samples should also be done. In this study, the professional attitudes of clinical professors and experts on different dimensions and components of medical professionalism in the professional character evaluation instrument was examined. Other assessment instruments, such as the opinions of students, residents, and even patients, can complement this study. The lack of questionnaire questions makes it impossible to make accurate judgments about the superiority of attitude in one area over other areas. Also, the individual characteristics of the statistical community may affect their attitudes toward the of medical professionalism in the tool of assessing their professional character, which in this research could not be studied in detail.
