Article InfoBackground: Organizational commitment is of considerable importance to nurses working to maintain, restore, and promote human health. One of the factors associated with organizational commitment is the quality of services offered to nurses by hospitals. The present study aims to determine the relationship between organizational commitment and the quality of services offered to nurses by hospitals. Materials & Methods: This descriptive-correlational study was conducted in 2017. A total of 150 nurses working at Seyed al-Shohada Heart Center in Urmia were enrolled in this study using a census. Data collection was conducted using a demographic questionnaire, Allen and Meyer's Organizational Commitment Scale, and Ashill's Scale of Service Delivery Performance. In addition, data were analyzed by descriptive statistics and the Pearson's correlation coefficient using SPSS V.16.0, Chicago, Illinois. Results: The results indicated that organizational commitment was at a moderate level among 67.3% of the nurses, and the quality of services offered by the hospital to 72% of the nurses was determined as relatively high. Moreover, the overall score of organizational commitment was found out to be linearly and significantly correlated with the overall score of the quality of services offered to nurses by the hospital as well as all of its dimensions (r=0.474, p=0.05). Conclusions: There appeared to be a significant positive correlation between the quality of services offered to nurses by the hospital and organizational commitment. Therefore, hospital authorities could improve the quality of services provided to nurses, thereby promoting their organizational commitment. This will in turn lead to an improvement in patient care.
