A manual examination of 3 primary oncology nursing journals was conducted to identify quantitative studies about chaplains and community-based clergy that were published between 1990 and 1999. This systematic review identified 7 studies involving chaplains and/or clergy dealing with a range of issues. Although the rate at which such studies were published in the oncology nursing literature was relatively low (1 in 123 studies), this rate far exceeds the rate found in a similar review of psychology journals (1 in 600 studies). The nature of the 7 studies and the issues they addressed are discussed and the authors make recommendations for future collaborative efforts.
