Examining the psychosis continuum
Open accessAbstract
The notion that psychosis may exist on a continuum with normal experience has been proposed in multiple forms throughout the history of psychiatry. However, in recent years there has been an exponential increase in efforts aimed at elucidating what has been termed the 'psychosis continuum'. The present review seeks to summarize some of the more basic characteristics of this continuum and to present some of the recent findings that provide support for its validity. While there is still considerable work to be done, the emerging data holds considerable promise for advancing our understanding of both risk and resilience to psychiatric disorders characterized by psychosis.

Genetic, neuropsychological, social, and environmental findings support a fully dimensional model in which nonclinical psychotic-like experiences and diagnosable psychotic disorders lie at opposite ends of a continuous distribution.
“Convergent genetic, neuropsychological, social, and environmental findings support a “fully dimensional” model of psychosis or schizotypy, in which nonclinical psychotic-like experiences and diagnosable psychotic disorders form opposite ends of a continuous distribution (Claridge & Beech, 1995; DeRosse & Karlsgodt, 2015; M. T. Nelson et al., 2013).”

The section “Evidence for Similarity Between Subclinical and Clinically Significant Psychosis” reviews genetic, demographic, experiential, and clinical evidence for a continuum; “Neurocognition” also discusses cognitive findings. But “Defining the Psychosis Continuum” says it is not yet clear whether the quasi-dimensional or fully dimensional model best fits the data. The paper therefore supports continuity, not the claim that these findings establish the fully dimensional model. (LLM, conf=0.90)
Experimental — accuracy not yet measuredLittle attention has been given to investigating whether the psychotic symptoms of healthy individuals are phenotypically similar to those of clinical populations.
“Further, little attention has been given to investigating whether the psychotic symptoms of healthy individuals are phenotypically similar to those of clinical populations (DeRosse and Karlsgodt, 2015).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
