Investigating the Mediating Role of Perceived Organizational Support in the Relationship between Sense of Coherence (SOC) and Professional Ethics, and Job Performance of Nurses

Background: Job performance is one of the most fundamental concepts in organizations, based on which, the responsibilities and success of each individual in the organization are formed.  The main objective of the current study was to investigate the mediating role of perceived organizational support in the relationship between sense of coherence (SOC) and professional ethics, and the job performance of nurses in Ahvaz City. Methods: It was a model-based testing research. The statistical population included all the nurses working in Golestan Hospital of Ahvaz City in 2019, among them, 252 nurses were selected as the sample of the study using the voluntary sampling method. The research instruments included Paterson's Job Performance Questionnaire, the Sense of Coherence (SOC) Scale, Professional Ethics Questionnaire, and Survey of Perceived Organizational Support (SPOS). Model fit was evaluated using path analysis with AMOS software. Results: The results showed that all the direct paths, except for the path from sense of coherence to job performance were significant (p <0.01). Moreover, the indirect paths through perceived organizational support to job performance were also significant (p<0.01). Conclusion: According to the results of the study, the proposed model had a good fit, and it can be considered as an important step towards identifying the factors affecting the job performance of nurses.
