(1) Background: Different investigations relate mindfulness practice as a strategy to cope
with and improve negative repetitive thinking states and forgiveness. (2) Methods: The aim is to
analyze the mediating processes of mindfulness as a trait and the changes in the anger rumination on
forgiveness. This sample comprised 264 undergraduate students (M = 24.13 years, SD = 11.39). The
instruments used were the Anger Rumination Scale (ARS), the Five Facet Mindfulness Questionnaire
(FFMQ) and the Heartland Forgiveness Scale (HFS). For data analysis, the spillover effect was
calculated using 10,000 bootstrap samples for the bootstrap confidence intervals (CI). (3) Conclusions:
The results confirm that the relationship between mindfulness practice and forgiveness is mediated
by changes in mindfulness trait and anger rumination. Given the results obtained, it is considered
appropriate to extend the study to samples from other countries, as well as to contexts of depressive
rumination or anxiety.
