Abstract
            Background. Human capital is the most vital strategic  element and the most basic way to improve the performance and efficiency of an  organization. Concerning the importance of human resources, it is obvious that  in order to achieve the goals of the health system, human resources must have a  favorable sense of belonging and commitment in addition to skills and  expertise. Based on this, the current study aimed at providing a structural  model for predicting professional commitment based on the components of  self-leadership among the employees of a medical science university.
  Methods. The current  applied research utilized a descriptive-correlational design. The statistical  population of the employees of Tabriz University of Medical Sciences (northwest  of Iran) was 976. Of this amount, 276 individuals were estimated as the  statistical sample based on Cochran's formula and were randomly selected. Data  were collected randomly through a questionnaire. In this study, structural  equation modeling based on PLS3 software was used to test the hypotheses.   
  Results. The results indicated  that the components of self-leadership-visualization of  successful performance, personal goal setting, self-rewarding, evaluation of  beliefs and assumptions, personal observation, focusing on natural rewards, and  self-guidance had a positive effect on professional commitment among the  employees of Tabriz University of Medical Sciences. What is more, the  components of self-leadership positively predicted professional commitment.
  Conclusion. Strengthening  the components of self-leadership among employees will lead to the improvement  of their morale, job satisfaction, and professional commitment, and in general,  a better manifestation of lofty goals and a significant increase in the  performance of the organization.
         
        
 
        
	
            
              Extended Abstract
    Background
      Organizational  leadership is one of the key issues in management. Among the issues that have  been discussed a lot in the field of organizational management and leadership  from the point of view of western theorists is the issue of leadership over  oneself and its priority over the management and leadership of others. On the  other hand, human capital is the most vital strategic element and the most  basic way to improve the performance and efficiency of an organization. Concerning  the importance of human resources, it is obvious that in order to achieve the  goals of the health system, human resources must have a favorable sense of belonging  and commitment in addition to skills and expertise. Based on this, the current study  aimed at providing a structural model for predicting professional commitment  based on the components of self-leadership among the employees of a prestigious  medical science university.   
  Methods
     The present study was practical  in terms of purpose, correlational in terms of design, and survey-based on  structural equations in terms of strategy. The study was conducted in Tabriz  University of Medical Sciences in Iran. This university is a prestigious  medical science university which is ranked 5th based on national  accreditation of Ministry of Health and Medical Education in Iran. The  employees, statistical population of this study, consisted of 976 people based  on the statistics of the Human Resources Management Unit in 2019. Based on  Cochran's formula, 276 people were selected using stratified random sampling.  In order to collect data, two questionnaires were used. The first questionnaire  was the standard questionnaire developed by Jeffrey Hoffman and Neck in 2002,  which measured self-leadership based on nine dimensions: visualization of successful  performance measures, personal goal setting, self-talk, self-rewarding,  evaluating beliefs and assumptions, self-punishment, self-observation, focusing  on natural rewards, and self-direction. The second questionnaire was Arnold's  standard questionnaire developed in 2007, which measured professional  commitment. To calculate the validity of the research tools, formal or symbolic  validity and convergent validity were used, which were approved by competent professors  and experts. In order to analyze the reliability of the tools, Cronbach's alpha  coefficient and combined reliability were used, and the Cronbach's alpha  coefficients of all variables (self-leadership 0.929, professional commitment  0.975) were determined to be greater than 0.7, and the reliability of the  research tools was confirmed. Data analysis was done using the structural  equation modeling method based on SMART PLS3 software.   
    Results
     Statistical analysis,  experiments, and data analysis of the current study were carried out at two  descriptive and inferential levels with SPSS and PLS3 statistical software, and  detailed outputs were analyzed and documented based on related figures and  tables. According to the results, the components of self-leadership-visualization  of successful performance, personal goal setting, self-rewarding, evaluation of  beliefs and assumptions, personal observation, focusing on natural rewards, and  self-guidance had a positive effect on professional commitment among the employees  of Tabriz University of Medical Sciences. What is more, the components of self-leadership  positively predicted professional commitment. In line with these findings, it  can be stated that human resources are the most important capital of  organizations. Organizations always try to maximize the leverage of human  resources and get the most benefit from their human resources. When this is  related to the self-management of employees, the importance of this issue  becomes more visible. On the other hand, people working in the health sector always  face many stressors. As such, due to the stressful nature of the profession,  their mental health faces a serious threat, and in the long run, it can cause  them to burn out. Therefore, the success of any organization lies in the hands  of its employees. The two magic words that make employees engage and perform  better at work are morale and commitment. Professional commitment leads to  reducing burnout, increasing job satisfaction, and ultimately increasing  service quality. 
  Conclusion
     One of the indicators of  the superiority of an organization over another organization is having  self-directed and committed human resources that reflect the image of the  organization in society and lead to an increase in job satisfaction,  self-efficacy, creativity, and innovation in the organization. Based on the results of  the study, managers should provide appropriate and relevant training courses  and workshops for employees to master their jobs in terms of strengthening  their self-confidence in using their imagination to depict important tasks,  visualizing themselves as successful people, creating a successful image of doing  the task in the mind before doing the task, and creating a purposeful  visualization of overcoming the challenges.
