In psychiatry, mood congruence is the congruence between feeling, or the emotion that a person is experiencing, and affect display, or the manner in which that emotion is "presenting", or being expressed.

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 in the case of depression, while they would be mood-congruent in a person experiencing mania.

Often refers to mood-congruent delusions. Manic delusions include delusions of reference, religiousity, grandiosity. Depressive delusions include intense feelings of guilt, feeling as though they are responsible for a terrible crime, delusions of persecution as well as thought-blocking, thought-insertion and thought-withdrawal.

Examples:

• Congruent mood - smiling while feeling happy.
• Non-congruent mood - smiling while feeling anxious.
• Inappropriate affect - laughing while describing a loved one's funeral, for instance.

Mood Congruenct is strongest when people try to recall personally meaningful episodes, because such events were most likely to be colored by their moods.
