Epidemiological studies of schizophrenia

  title={Epidemiological studies of schizophrenia},
  author={Judith Allardyce},
In this paper, we discuss the conceptual background for including a dimensional component to the DSM V diagnoses for psychoses. We review the evidence for a continuous distribution of psychosis like symptoms in the general population and summarise the research validating the clinical usefulness of psychopathological dimensions. We conclude that diagnostic models using both categorical and dimensional representations of psychosis have better predictive validity than either model independently…

A comparison of the utility of dimensional and categorical representations of psychosis

A dimensional approach towards classification of psychotic illness offers important clinical advantages and is likely to provide clinically useful information on need for care.

Domains of Psychopathology: An Approach to the Reduction of Heterogeneity in Schizophrenia

There is now considerable evidence supporting the separation of schizophrenic symptoms into three domains: hallucinations and delusions, thought disorder, and deficit symptoms.

Characterization of psychotic conditions. Use of the domains of psychopathology model.

The results suggest that these psychopathological domains previously described in schizophrenia are not unique to schizophrenia and may each correspond to a discrete pathophysiologic condition.

Deficit and nondeficit forms of schizophrenia: the concept.

The authors provide a rationale for distinguishing the primary, enduring negative symptoms of schizophrenia from the more transient negative symptoms secondary to other factors and propose criteria for defining schizophrenia with the deficit syndrome.

The dimensional structure of first episode psychosis: an exploratory factor analysis

The data failed to support the three-syndrome model for non-affective symptoms in this population, and the findings have implications for the conceptualization of early psychosis, which need to be explored further in validation studies.

Dimensions and classes of psychosis in a population cohort: a four-class, four-dimension model of schizophrenia and affective psychoses

OPCRIT analysis of data reduction methods of symptom profiles within a population-based cohort of people with a wide range of affective and non-affective psychoses suggests such findings could represent discrete pathological conditions.

Classifying psychotic disorders: issues regarding categorial vs. dimensional approaches and time frame to assess symptoms

It is concluded that classification of psychotic disorders is highly dependent upon the time frame considered to assess symptoms and that dimensional classifications do have higher predictive power than categorical ones.

Psychopathological syndromes in the functional psychoses: associations with course and outcome

It was found that dimensional representations of psychopathological features were considerably more useful than categorical representations (DSM-III-R and ICD-10) as predictors of illness course and treatment decisions.
