Abstract

Background Not all persons identified in the early stages to be at risk for psychosis eventually cross the threshold for a psychotic illness. However, sub-clinical symptoms may not only indicate a specific risk but also suggest a more general, underlying psychopathology that predisposes one to various common mental disorders.Methods Analyzing data from the prospective Zurich Cohort Study, we used two psychosis subscales - "schizotypal signs" and "schizophrenia nuclear symptoms" - derived from the SCL-90-R checklist that measured sub-clinical psychosis symptoms in 1979. We also assessed 10 different diagnoses of common mental disorders through seven interview waves between 1979 and 2008. This 30-year span, covering participant ages of 19/20 to 49/50, encompasses the period of highest risk for the occurrence of such disorders.Results Both psychosis scales from 1979, but especially "schizotypal signs", were significantly correlated with most mental disorders over the subsequent test period. Higher values on both subscales were associated with an increasing number of co-occurring disorders.Conclusions Our data demonstrate that sub-clinical psychosis generally represents a risk factor for the development of common mental disorders and a liability for co-occurring disorders. This refers in particular to dysthymia, bipolar disorder, social phobia, and obsessive-compulsive disorder. Proneness to psychosis could signal a fundamental tendency toward common mental disorders.

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.
