Twelve questions, about two minutes. Bring to mind one specific person and one specific hurt, and answer about that — not about forgiveness in general.
This places you on Enright's four-phase model of forgiveness (Enright & Fitzgibbons, 2000), using items written around the motivations the research measures: avoidance, revenge and benevolence. It is a reflective tool, not a clinical or diagnostic test, and it has not been validated as a psychometric instrument. Nothing you write is stored against your name.
