Guilt plays a role in various forms of psychopathology. However, different types of guilt might be involved in different mental disorders. Obsessive-compulsive (OC) patients are prone to a type of guilt in which the violation of an internalized moral norm is necessary and sufficient, whereas data suggest that depression might be linked to more interpersonal types of guilt. However, the extent to which a specific guilt phenomenology is involved in each condition is yet to be determined. Here we assessed the association between different types of guilt and different diagnostic groups. Two clinical samples (33 OCD and 35 non-OCD) filled in the Moral Orientation Guilt Scale (MOGS) along with other OCD and depression measures. Regression was employed to test group differences in the MOGS subscales and to test the influence of MOGS subscales on OCD and depression levels. Results confirm that different types of guilt might be implicated in different psychopathological conditions. Specifically, moral norm violation guilt is more present in OC patients than in other disorders. Depression seems to be associated with different guilt feelings depending on the psychopathological condition, specifically in non-OC patients, with types of guilt involving a "victim", supporting the accounts viewing interpersonal guilt as involved in the emergence of depressive symptomatology and hyper-altruistic behavior as a vulnerability factor for depression.
