Una recente pubblicazione della British Psychological Society fa una messa a punto dello stato dell'arte nella conoscenza delle psicosi e della schizofrenia, concludendo che possono essere comprese e trattate nello stesso modo come altri problemi psicologici quali l'ansia e la timidezza.

Executive Summary (draft)

This report describes a psychological approach to experiences that are commonly thought of as psychosis, or sometimes schizophrenia. It complements parallel reports on the experiences commonly thought of as bipolar disorder and depression.

Hearing voices or feeling paranoid are common experiences which can often be a reaction to trauma, abuse or deprivation. Calling them symptoms of mental illness, psychosis or schizophrenia is only one way of thinking about them, with advantages and disadvantages.
There is no clear dividing line between ‘psychosis’ and other thoughts, feelings and beliefs: psychosis can be understood and treated in the same way as other psychological problems such as anxiety or shyness. Significant progress has been made over the last twenty years both in understanding the psychology of these experiences and in finding ways to help.
Some people find it useful to think of themselves as having an illness. Others prefer to think of their problems as, for example, an aspect of their personality which sometimes gets them into trouble but which they would not want to be without.
In some cultures, experiences such as hearing voices are highly valued.
Each individual’s experiences are unique – no one person’s problems, or ways of coping with them, are exactly the same as anyone else’s.
For many people the experiences are short-lived. Even people who continue to have them nevertheless often lead happy and successful lives.
It is a myth that people who have these experiences are likely to be violent.
Psychological therapies – talking treatments such as Cognitive Behaviour Therapy (CBT) – are very helpful for many people. In the UK, the National Institute for Health and Care Excellence recommends that everyone with a diagnosis of psychosis or schizophrenia should be offered talking therapy. However most people are currently unable to access it and we regard this situation as scandalous.
More generally, it is vital that services offer people the chance to talk in detail about their experiences and to make sense of what has happened to them. Surprisingly few currently do. Professionals should not insist that people accept any one particular framework of understanding, for example that their experiences are symptoms of an illness.
Many people find that ‘antipsychotic’ medication helps to make the experiences less frequent, intense or distressing. However, there is no evidence that it corrects an underlying biological abnormality. Recent evidence also suggests that it carries significant risks, particularly if taken long term.
The British Psychological Society believes that services need to change radically, and that we need to invest in prevention by taking measures to reduce abuse,
