This field study involves a bottom-up assessment of the quality of leadership, communication, and organizational citizenship in a military hospital, as reported by employees that are directly involved with operations that affect patient outcomes. In particular, measures of the quality of Leader-Member Exchange (via the LMX-7 questionnaire), Communication Satisfaction (via the CSQ questionnaire), and Organizational Citizenship (via the OCB questionnaire) were obtained from a survey of over 1,000 personnel throughout the military medical center. The study examined how these measures are influenced by a variety of individual employee demographic variables: status, military rank, time on station, time in service, gender, race. The degree to which each employee demographic factor influenced the resulting scores for leadership, communication, and organizational citizenship are analyzed. This analysis shows that personnel with less than 6 months time on station had higher LMX and CSQ scores. Racial identity had a significant effect with OCB and CSQ communication climate. Time on station had a significant effect on LMX and overall CSQ including dimensions. Time on station, time in service and rank had a combined effect on CSQ including dimensions. Participants who were the same gender as their supervisors had higher overall CSQ, communication climate and corporate information. Overall results from this field study show interesting data related to leadership, communication and citizenship behavior in a military hospital. Implications for future research are noted.
