AbstractDespite theory suggesting that self‐forgiveness facilitates recovery from moral injury, no measure of self‐forgiveness has been validated with individuals exposed to potentially morally injurious events (PMIEs). Military veterans, healthcare workers, and first responders who reported PMIE exposure (n = 924) completed the Self‐Forgiveness Dual‐Process Scale, which assesses two dimensions of the self‐forgiveness process. The first dimension, value affirmation, refers to appraising personal responsibility and being willing to make amends for one's involvement in a PMIE. The second dimension, esteem restoration, refers to accepting oneself as valuable and capable of growth despite one's failures and imperfections. Exploratory and Confirmatory Factor Analyses replicated the original scale's two‐factor structure in 10 items modified to apply to the diverse contexts in which PMIEs occur. Next, we found that the factor structure, item loadings, and item intercepts were fully or partially invariant across professions, genders, races, ages, and religious affiliations in a series of Multi‐Group Confirmatory Factor Analyses. Finally, diverging patterns of associations between value affirmation and esteem restoration with moral distress, posttraumatic stress, depression, insomnia, functional impairment, and posttraumatic growth provide evidence of convergent and discriminant validity between the subscales. The modified self‐forgiveness dual process scale is the first measure of self‐forgiveness to be validated with individuals exposed to a PMIE. Researchers and clinicians can use the scale to examine how self‐forgiveness (or difficulties with forgiving oneself) relates to moral injury.
