Prevalence of delusional jealousy in different psychiatric disorders. An analysis of 93 cases.

Abstract

The prevalence of delusional jealousy in 8134 psychiatric in-patients was 1.1%. Delusions of jealousy were most frequent in organic psychoses (7.0%), paranoid disorders (6.7%), alcohol psychosis (5.6%) and schizophrenia (2.5%), while in affective disorder delusions of jealousy could be found in only 0.1%. Because schizophrenia and affective disorder were the most common diagnoses, most patients with delusions of jealousy were schizophrenics. In schizophrenia, women were more likely to suffer from delusional jealousy, while in alcohol psychosis, men were more likely than women to suffer from delusional jealousy.
