Forgiveness is currently being researched in various settings, which requires that scientists to have instruments with psychometric properties suitable for its evaluation. The objective of this article is to identify, select, and critically analyze psychometric research on forgiveness to identify its trends, limitations, and contributions to science. The method used was based on the PRISMA 2020 Statement and the Scopus, Web of Science, Ebsco, Proquest, Scielo, and Dialnet databases from 2017 to 2022 were consulted. Fourteen out of 334,339 studies met the inclusion criteria. The results evidence that 79% used nonprobability sampling, 21% reported the construction of new instruments, and 36% obtained evidence of metric invariance. Peru and Chile lead the psychometric production of forgiveness (both with 21.4%) followed by the United States, Brazil, Mexico, and Argentina, which share an equal 14.3%. Implications of the findings have been discussed.
