The Proper Calculation of Risk Ratios: How and Why
1Department of Psychological Science, Auburn University, Auburn, AL USA.
Abstract:
A recent article (Joslyn, P. R., & Morris, S. L. in Perspectives on Behavior Science, 47(1), 167-196, 2024) advocates the use of risk ratios, or relative risk, in behavior analysis. The authors present a strong case for the use of risk ratios and how they might improve the science and application of behavior analysis. Unfortunately, their computation of the risk ratio is incorrect and their examples gloss over important nuances in how risk ratios should be used. The present article corrects the calculations, describes how to determine whether a particular risk ratio differs from a reference group, comments on the importance of stability of the data entering the calculation, and demonstrates approaches to presenting them visually, such as Forest plots.
