The perception of being a burden to others has been associated with suicidal ideation and behavior. Maladaptive aspects of perfectionism have also been associated with suicidal thinking and behavior. The purpose of the current study was to investigate whether perceived burdensomeness would act as a mediator between maladaptive perfectionism and suicidal ideation. Results indicated that perceived burdensomeness mediated the relationship between maladaptive perfectionism and suicidal ideation, which suggest that the perception of burdensomeness may be one aspect of the mechanism by which perfectionism can lead to such psychological distress that it becomes a predictor of suicidal ideation. Clinical implications of this relationship are discussed.
