The effects of organizational communication on job satisfaction and organizational commitment in a land ambulance service and the mediating role of communication satisfaction

The purpose of this paper is to provide further insight into the relationship between internal communication practices, communication satisfaction, job satisfaction, and organizational commitment. It is centered in the emergency services sector in general, and on land ambulance services in particular. The focus organization is a large urban land ambulance service with an operating budget of approximately $50 million and 468 employees.

Only paramedics were eligible to participate in the study. In total, 91 (32.5 per cent) of the organization's 280 paramedics participated. Data were collected using a questionnaire comprising pre‐existing work‐related psychometric measures. The measures included the Communication Audit Survey, the Communication Satisfaction Questionnaire, the Minnesota Satisfaction Questionnaire and the Affective Organizational Commitment Scale. Only quantitative data were collected.

The data showed that internal communication practices explained 49.8 per cent of the variation in communication satisfaction, 23.4 per cent of the variation in job satisfaction, and 17.5 per cent of the variation in affective organizational commitment. However, these effects were fully mediated by communication satisfaction when job satisfaction and affective organizational commitment were regressed against both internal communication practices and communication satisfaction.

These findings have important practical and theoretical implications. Managers will not be able to foster job satisfaction and affective organizational commitment through internal communication practices unless they recognize and appreciate what information is valued by employees. Second, managers must have a clear understanding of both the quantity and quality of information desired by employees if they are to design internal communication systems that meet the information needs of employees. Finally, one must consider the possibility that, for employees, communication satisfaction represents a fundamental yardstick against which all of the organization's activities and change initiatives are measured. This possibility is supported by research from the domain of change management.

Given the present shortage of skilled and able emergency personnel, it is in the best interest of organizations to enhance job satisfaction and commitment of such critical employees.
