U.S. Army doctrine defines leadership around the ability to influence (Department of the U.S. Army, 2006) and accordingly, Army leaders have decided that extending influence is a vital part of any future leadership training requirements (Horey, Fallesen, Morath, Cronin, Cassella, Franks, Jr., & Smith, 2004). The literature reveals, however, a significant research-to-practice gap between actual influence behavior and what has been quantitatively understood. This study sought to partially remedy this gap by examining the actual influence tactics of one branch of the U.S. Army: the chaplain corps. The purpose of this quantitative study was to investigate the influence tactics of U.S. Army chaplains on their chaplain assistants and gain knowledge relating to tactic effectiveness. This study used an online format to implement a descriptive, quantitative, cross-sectional survey research design using the target survey version of the Influence Behavior Questionnaire (IBQ) (Yukl et al., 2008). The entire population of chaplain assistants (about 2700) were asked to participate with 337 responding. Participants were asked to complete the IBQ with their current chaplain as the target and then to rate the effectiveness of the influence tactics in a separate effectiveness question. The results indicate that the chaplain targets make much use of consultation, rational persuasion, ingratiation, and collaboration. There was a disjuncture, however, between the typical influence tactics of the chaplains and their perceived effectiveness by the chaplain assistants. For example, chaplain assistants ranked pressure and apprising as more effective in influencing them in specific tasks. It appears that the chaplains and their chaplain assistants were operating from two different professional paradigms. The study concluded with implications for influence training and upon chaplaincy practice along with future recommendations for continuing research.
