Concern has been expressed as to the reliability of clinical ICD-10 diagnosis of schizophrenia. This study was designed to assess the diagnostic reliability of the clinical ICD-10 diagnosis of schizophrenia in a random sample of Danish in- and outpatients with a history of psychosis. A sample of 100 subjects was assessed using the operational criteria OPCRIT checklist for psychotic and affective illness. The most recent principal and clinical ICD-10 diagnosis was compared with diagnoses… 
Reliability of clinical ICD-10 diagnoses among electroconvulsive therapy patients with chronic affective disorders
TLDR
This study demonstrates that the reliability of clinical ICD-10 diagnoses of affective disorders from chronic subjects with a history of ECT is problematic despite sample homogeneity on basic clinical, demographic and epidemiological parameters.
Characterization of Patients with Schizophrenia and Related Psychoses: Evaluation of Different Diagnostic Procedures
TLDR
Structured interviews performed with Swedish long-term-treated psychosis patients during non-hospitalization are a poor source for the evaluation of psychosis diagnoses, but a good screening instrument for the detection of DSM-III-R schizophrenia.
Diagnosis and Classification of the Schizophrenia Spectrum Disorders
TLDR
This chapter discusses past and present diagnostic classifications of schizophrenia spectrum disorders, and research considerations for further improving the nosological system.
Competing definitions of schizophrenia: what can be learned from polydiagnostic studies?
TLDR
It seems that a century after the introduction of the sz concept, research is still badly needed, concerning conceptual and construct validity of sz, its essential psychopathological features, and phenotypic boundaries.
Evaluation of data obtained from military disability medical administrative databases for service members with schizophrenia or bipolar disorder.
TLDR
High levels of agreement between investigators and database diagnoses indicate that diagnostic misclassification is unlikely and discharge procedure initiation date provides a suitable surrogate for disease onset.
Self-disorders and the Schizophrenia Spectrum: A Study of 100 First Hospital Admissions
TLDR
The study lends validity to the view of SD as an experiential vulnerability phenotype of the schizophrenia spectrum disorders by exploring correlations between SD and the canonical psychopathological dimensions of schizophrenia.
Preceding diagnoses to young adult bipolar disorder and schizophrenia in a nationwide study
TLDR
Overall patients with SZ had a minor but statistically significant earlier onset of any psychiatric disorder compared to BD, while SZ was associated with an increased risk of preceding substance use disorders, psychosis, anxiety disorders, and personality disorders.
A review of the reliability and validity of OPCRIT in relation to its use for the routine clinical assessment of mental health patients
TLDR
A review of studies which had used OPCRIT and had reported statistics concerning its reliability and validity produced summary measures from 44 studies, which will be considered during the preparation for its use in the routine characterization of mental health patients in clinical settings.
Variations in incidence and age of onset of acute and transient psychotic disorders
TLDR
Findings are likely to reflect the heterogeneity of the clinical features encompassed by ATPDs, and contribute to building a case for their revision in ICD-11, as well as highlighting differences from schizophrenia and bipolar affective disorder.
Self-Disorders, Neurocognition and Rationality in Schizophrenia: A Preliminary Study
TLDR
The lack of correlation between SDs and neurocognitive performance is consistent with the results from the only previous study exploring this issue, suggesting that SDs depict something essential to schizophrenia, whereas neuroc cognitive impairment does not.

Using consensus OPCRIT diagnoses
TLDR
Results suggest that the OPCRIT procedure for diagnostic assessment is an efficient alternative to classic best-estimate diagnosis procedures.
Exploring boundaries of schizophrenia: a comparison of ICD-10 with other diagnostic systems in first-admitted patients.
TLDR
Although the contemporary DSM and ICD criteria for schizophrenia are a convention of unknown validity as compared to their potential rival definitions, these criteria are being increasingly considered by the residents and the younger colleagues as the criteria which somehow must reflect the true nature or essence of this disorder.
Diagnostic stability in subjects with multiple admissions for psychotic illness
TLDR
The stability levels for schizophrenia and affective disorders are adequate, but the low levels for a range of other psychotic conditions raise questions regarding their predictive validity.
Major psychoses symptomatology: factor analysis of 2241 psychotic subjects
TLDR
To identify the symptomatologic structure common to major psychoses based on lifetime symptoms, two thousand and forty-one inpatients affected by schizophrenic, bipolar, major depressive, delusional, delusional and psychotic not otherwise specified disorder were surveyed.
Polydiagnostic approaches to measuring and classifying psychopathology.
TLDR
A polydiagnostic approach is advocated whereby research data are collected in such a way as to allow the application of competing definitions of disorder.
Genetic variation in the 6p22.3 gene DTNBP1, the human ortholog of the mouse dysbindin gene, is associated with schizophrenia.
TLDR
Family-based association analysis of 36 simple sequence-length-polymorphism markers and of 17 SNP markers implicated two regions, separated by approximately 7 Mb, that are strongly associated with schizophrenia, and it is concluded that further investigation of dysbindin is warranted.

A multicentre inter-rater reliability study using the OPCRIT computerized diagnostic system
TLDR
The OPCRIT system, is both flexible and practicable retaining the 'top-down' advantage of operational definitions as well as the 'bottom-up' potential offered by well defined signs, symptoms and other component items.
