Interpreting and inverting with less cursing: A guide to interpreting IRAP data

•The IRAP is a procedure used to assess the "strength" of relational responding.•We clarify the steps involved in scoring and interpreting IRAP data.•Correct scoring and inversion techniques are key to appropriate statistical analysis.

This Professional Interest Brief seeks to provide a clear guide to interpreting data generated by Implicit Relational Assessment Procedure (IRAP). The interpretation of IRAP data is not immediately intuitive and yet has received little explicit attention in the published literature. As such, it is hoped that this guide will help clarify this matter, particularly for those new to using the IRAP or intending to use the measure in the future. In doing so, we hope to make the measure more accessible and facilitate continued use of the methodology and its contribution to the contemporary Relational Frame Theory (RFT) literature.
