Content of grandiose phenomenology across cultures

The content of grandiose ideas and delusions in patients of various cultural groups admitted to a London psychiatric hospital were compared. There were no overall differences but certain trends were apparent. It was found that religion was the commonest content of grandiose symptoms in all the groups. Its frequency was higher in the African and Jamaican groups, an observation that can be understood from the cultural background of these groups. The other types of content, namely royals, identity and ability were less frequent in all groups.
