INTRODUCTION: The purpose of this study is to compare the differences in mentorship expectations and attitudes between Army and civilian healthcare leaders, and to review cultural differences between the Army and civilian sectors. MATERIALS AND METHODS: This study used survey data from Army Medical Service Corps officers and members of a regional chapter of the American College of Healthcare Executives (ACHE) to compare attributes of, and attitudes toward, mentorship. A principal component analysis was used to develop three broad mentorship factors, and a comparison of individual attributes was conducted between populations. Institutional approval (IRB) was granted by the University of New Hampshire (IRB #: 6676). RESULTS: The principal component analysis showed similar underlying factors for both populations. An attribute level comparison demonstrated important differences in attitudes toward mentors and mentoring between the Army and civilian participants. CONCLUSION: The differences between the Army and civilian samples appear to arise from differences in their respective cultures. The utilization by the Army of formal training programs such as the Army's Basic Officer Leadership Course (BOLC), fill a need provided by mentors in civilian organizations. The common experience of professional training like BOLC is part of what creates and sustains the "thick" culture of the Army. Former Army members making the transition to a civilian career should bear in mind that they are leaving behind a thick culture, and that individual relationships may have greater impact on their future careers than they had experienced in the Army.
