Schizotypy from a developmental perspective

Open access
Debbane, M., Barrantes-Vidal, N.·2015·Schizophrenia Bulletin

Abstract

The schizotypy construct focuses attention on the liability to develop schizophrenia-spectrum disorders, yet traditionally, the schizotypy models have put more emphasis on stress-vulnerability interactions rather than developmental dynamics of emerging risk for psychopathology. Indeed, developmental accounts of this emerging personality trait have rarely been explicitly formulated. In this position article, we wish to convey some of the basic developmental tenets of schizotypy, and how they can inform high-risk research. Firstly, we tackle the state vs trait issue to outline the possible relationship between high-risk states and trait schizotypy. Second, we review the evidence suggesting that the consolidation of schizotypy, encompassing its 3 main dimensions, could be considered as a developmental mediator between very early risk factors and transition into high-risk states. Importantly, developmental dynamics between endophenotypes, as well as transactional and epigenetics mechanisms should enter modern conceptualizations of schizotypy. Finally, we present a developmental psychopathology perspective of schizotypy sensitive to both the multifinality and equifinality of schizophrenia-spectrum disorders. We conclude that schizotypy represents a crucial construct in a fully-developmental study of schizophrenia-spectrum disorders.

  • Narrative self-disturbances likely follow the same developmental pattern as other psychotic symptoms, beginning in earlier or milder forms of psychosis before becoming severe enough for clinical attention in SSD.

    “Research findings in these populations can therefore shed light on the developmental trajectory of narrative self-disturbances, which likely follow the same pattern as other psychotic symptoms, originating in earlier or milder forms of psychosis before becoming severe enough to warrant clinical attention in SSD (Barrantes-Vidal et al., 2015; Debbané & Barrantes-Vidal, 2015).”

    From Narrative identity in the psychosis spectrum: A systematic review and developmental model (2021) · cites this paper as Debbané & Barrantes-Vidal, 2015

    The Conclusion describes a developmental pathway in which schizotypy can confer liability to psychotic states and may ultimately lead to schizophrenia-spectrum disorders. The Introduction also links adolescent schizotypal symptoms to later help-seeking. Neither passage establishes that narrative self-disturbances specifically follow this trajectory; applying the general model to them is the citing authors’ inference. (LLM, conf=0.85)

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.
