“Psychoses are disorders that produce disturbances in thinking and perception severe enough to distort the perception of reality. The main types are schizophrenia and affective psychosis, such as bipolar disorder” (APMS 2007).

The overall prevalence of psychotic disorder was found to be 0.4% (0.3% of men and 0.5% of women). In both men and women the highest prevalence was observed in those aged 35 to 44 years (0.7% and 1.1% respectively).

Applying these assumptions to the West Sussex population means approximately 2,720 adults in West Sussex are estimated to have a psychotic disorder. Breaking these figures down to the CCG areas within the county:

Prevalence is estimated as being significantly higher for black men (3.1%); no significant differences are estimated in women. Prevalence estimates also varies according to household income, 0.1% of adults in the highest quintile to 0.9% of adults in the lowest quintile; a difference noted as being more prominent among men than women.
