This article provides community engagement researchers with an introduction to propensity score matching (PSM) methods. It explains why PSM can serve as a valuable method for evaluating the success of programs when random assignment of individuals to community engagement programs is not possible; it also addresses some of the advantages and challenges in using PSM. It then explains the steps in conducting a PSM study and illustrates them with an example drawn from research our team conducted. That research looked at the success of a community engagement program in which underrepresented college students mentored and tutored middle school students in their community.
