Stressful events provide clues to psychosis delusion content
Researchers have found links between the stressful events experienced by patients prior to their first episode of psychosis and the types of delusions and auditory hallucinations they suffer due to their condition.
"If life-event characteristics are related to the content of subsequent delusions and auditory hallucinations, this goes some way to refute the idea that symptoms of psychosis are without meaning and certainly has clinical implications," say David Raune (West London Mental Health Trust, London, UK) and colleagues.
The researchers assessed the stressful life events occurring in the year before psychosis onset in 41 people, along with the themes - persecutory, depressive, and grandiose - associated with their delusions and auditory hallucinations.
Analysis revealed that intrusive events, such as physical assault, being threatened with a knife, rape, and sexual disease infection, were associated with persecutory delusions and voices.
The researchers suggest in the journal Psychological Medicine, that this may be because intrusive stressful events can skew individual's ideas about the world, inducing suspicions about other people's intentions and a self-perception of vulnerability.
In contrast, depressive delusions were linked to danger events, while depressive auditory hallucinations were associated with intrusive events, which may be due to overlap with persecutory voice content.
However, there was no indication that loss events, including loss, self-esteem, and humiliation events, were associated with the development of depressive psychotic themes.
Grandiose themes were primarily associated with an absence of loss events, with grandiose delusions being a potential way of improving and maintaining self-esteem, regardless of whether it was initially low.
The researchers say that "incorporating recent stressful events into the assessment and psychological formulation of core psychotic themes may assist with patient engagement, normalization, and insight."
They explain: "Helping an individual to 'make sense' of how previous events relate to current symptoms should reduce anxiety, depression, and feelings of powerlessness, all of which seem to be associated with psychological appraisal."
