In psychology, symptoms are said to be mood-congruent if they are consistent with a patient's mood or mental disorder. Conversely, they are said to be mood-incongruent if they are inconsistent with their primary mood.

For example, suicide ideation in a patient suffering from Major Depressive Disorder would be a mood-congruent symptom. Likewise, feelings of omnipotence or other delusions of grandeur would be considered mood-incongruent symptoms.
