Schizophrenia is a severe mental illness that affects 1% of the population. The diagnosis is made according to current diagnostic systems of DSM-IV (American Psychiatric Association, 1994) and ICD-10 (World Health Association, 1992) on the basis of characteristic 'positive' and 'negative' symptoms. The traditional medical model assumes a categorical view of the schizophrenia syndrome and its core symptoms, in which differences between psychotic symptoms and their normal counterparts are… Expand

The psychosis continuum and categorical versus dimensional diagnostic approaches
TLDR
A comparison is presented between categorical and dimensional approaches to the diagnosis of psychosis by highlighting four advantages of each approach and it is emphasized that the categorical approach is beneficial primarily in terms of reliability, whereas the dimensional approach would enhance validity.

Psychotic features in the general population. Risk factors for what
For clinical purposes, psychosis is defined as a discrete entity that can be identified by applying certain criteria. This does not mean, however, that this condition exists as such in nature.Expand
Examining the continuum of psychosis: Frequency and characteristics of psychotic-like symptoms in relatives and non-relatives of patients with schizophrenia
TLDR
Rates of PLEs, however considered, do not differ substantially between relatives and non-relatives of patients with schizophrenia, and only a minority of Ples picked up by screening interviews resemble attenuated forms of psychotic symptoms. Expand

TLDR
The results of a literature review suggest that delusional and hallucinatory experiences are more common in the general population than the authors may think, and that there could well be a symptomatic continuum between people who have andPeople who have not been diagnosed with indisputable psychotic disorders.

The Negative Symptoms of Schizophrenia: Category or Continuum?
TLDR
Evidence that negative symptoms show a continuous distribution from apparently healthy subjects to those with a fully developed clinical syndrome justifies exploring a dimensional approach with respect to its clinical and scientific utility. Expand

Psychosis as an Extreme of Continuous Variation in Dimensions of Psychopathology
Anyone working in clinical psychiatry, especially the psychiatric hospital, is naturally inclined to think that psychosis reveals itself as “cases” in need of treatment. This clinical perspective hasExpand

The cognitive processes that are thought to lead to the formation and maintenance of the positive symptoms of psychosis are set out and a fuller integration with the findings of biological research will be required. Expand

Are there more than two syndromes in schizophrenia? A critique of the positive-negative dichotomy.
TLDR
A sample of 115 DSM-III-R schizophrenics was studied and it is argued that the authors are far from a valid classification of schizophrenic symptoms and the positive-negative dichotomy appears to be an oversimplification. Expand

TLDR
The psychopathological heterogeneity of these disorders argues against the assumption of a manifest psychopathological dimension with a continuous transition from the schizophrenic psychosis to the "normal" schizothymic personality, and leads to other epidemiological and genetic models than Kraepelin's early concept of a disease entity does.

Risk factors for onset and persistence of psychosis
TLDR
Evidence supporting the validity of a model of shared risk factors for continuous characteristics needs to be further elaborated and incorporated into the concepts of psychotic illness. Expand
Symptomatic and neuropsychological components of defect states.
TLDR
Preliminary findings of investigations in which symptomatic and neuropsychological assessments were conducted in a sample of chronic schizophrenic inpatients suggest that the "defect state" may not be a monothetic construct, and that within the domain of "type II" schizophrenia, disturbances of thought may be distinguished from those of affect and motivation.

TLDR
The notion of the discreteness of these symptoms encourages the conception of psychosis and schizophrenia as states that are also discrete and discontinuous and the further conception that patients with these diagnoses are somehow qualitatively different from other patients. Expand

TLDR
There are many legitimate concerns related to intervening in pre-psychotic individuals which must be understood by those involved in planning preventive interventions, and policies should be developed incorporating some of the ethical and economic concerns. Expand
