Abstract

This article reviews empirical studies of affective traits in individuals with schizophrenia spectrum disorders, population-based investigations of vulnerability to psychosis, and genetic and psychometric high-risk samples. The review focuses on studies that use self-report trait questionnaires to assess Negative Affectivity (NA) and Positive Affectivity (PA), which are conceptualized in contemporary models of personality as broad, temperamentally-based dispositions to experience corresponding emotional states. Individuals with schizophrenia report a pattern of stably elevated NA and low PA throughout the illness course. Among affected individuals, these traits are associated with variability in several clinically important features, including functional outcome, quality of life, and stress reactivity. Furthermore, evidence that elevated NA and low PA (particularly the facet of anhedonia) predict the development of psychosis and are detectable in high-risk samples suggests that these traits play a role in vulnerability to schizophrenia, though they are implicated in other forms of psychopathology as well. Results are discussed in terms of their implications for treatment, etiological models, and future research to advance the study of affective traits in schizophrenia and schizotypy.

  • Psychosis-spectrum samples are heterogeneous, with multiple symptom and trait profiles typically present in any given sample.

    “Moreover, psychosis-spectrum samples are heterogeneous, with multiple symptom and trait profiles typically present in any given sample (e.g., Cowan et al., 2020; Dickinson et al., 2018; Horan et al., 2008).”

    From Narrative identity in the psychosis spectrum: A systematic review and developmental model (2021) · cites this paper as Horan et al., 2008

    The Research Implications section describes schizotypy as a heterogeneous construct and identifies positive, disorganized, and negative symptom domains in schizophrenia and schizotypy. This supports the general point about differing symptom and trait profiles, but it does not establish that multiple profiles are typically present in any given psychosis-spectrum sample.

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.
