Psychiatry · Psychopathology: mood-congruent delusions
Sample itemIn a patient with severe depression, which delusion is mood-congruent?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Belief that he is responsible for the sins of the world and deserves punishment
Mood-congruent delusions match the depressed mood and include guilt, worthlessness, poverty, nihilism and hypochondriacal themes. Grandiose themes fit mania instead. Thought broadcast is a first-rank symptom and is mood-incongruent in this context.
Option by option
A. Belief that he is responsible for the sins of the world and deserves punishment (correct)
Correct. Guilt and deserved punishment fit a depressed mood.
B. Belief that he has special powers and a divine mission
Grandiose delusions are congruent with elevated mood in mania.
C. Belief that a famous actor is secretly in love with him
Erotomania is a delusional disorder theme and does not fit a depressive mood.
D. Belief that his thoughts are being broadcast to others
Thought broadcast is a Schneiderian first-rank symptom, which is mood-incongruent in affective psychosis.
