Abstract

A growing body of evidence suggests that resting cortisol levels are elevated in patients with schizophrenia and closely tied to symptom severity. However, there is limited research on the biological stress system during the ultra high-risk (UHR) period immediately preceding the onset of psychosis, and cortisol has not been examined in relation to individual characteristics such as self-concept or potential stressors such as putative familial environment in this critical population. In the present study, salivary cortisol samples were collected on 37 UHR and 42 matched control adolescents, and these individuals were assessed with clinical interviews as well as a measure of self-concept. For a subsection of the sample (23 UHR and 20 control adolescents), a participating relative/caretaker was also assessed with an expressed emotion interview designed to gauge psychosocial environment. Consistent with previous studies, UHR participants exhibited elevated resting cortisol levels when compared with controls. In addition, UHR adolescents exhibited increased negative self-concept and their relatives/caretakers endorsed significantly fewer initial positive statements about the participant. Interestingly, a strong trend in the UHR group suggests that higher cortisol levels are associated with higher rates of critical statements from relatives/caretakers. Furthermore, elevated cortisol levels in the participants were associated with increased negative self-concept as well as fewer initial positive comments from relatives/caretakers. Results suggest that hypothalamic-pituitary-adrenal axis (HPA) dysfunction is closely associated with both individual and environmental-level characteristics. Taken together, these findings support a neural diathesis-stress model of psychosis and future studies, designed to examine causal relationships, stand to inform both our understanding of pathogenic processes in the high-risk period as well as early intervention efforts.

  • General distress experienced early in life, such as through childhood trauma, bullying victimization, or unsupportive family environments, is a key vulnerability factor linked to future psychotic experiences.

    “One key vulnerability factor is general distress experienced early in life, for instance through childhood trauma, bullying victimization, or unsupportive family environments, all of which have been linked to future psychotic experiences (Carol & Mittal, 2015; Catone et al., 2015; Mayo et al., 2019; Wigman et al., 2012).”

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

    The Introduction (page unavailable) links family criticism and emotional over-involvement with symptoms in adolescents at ultra-high risk for psychosis. The Discussion (page unavailable) also treats family environment as a relevant stressor, but says longitudinal studies are needed to establish causal relationships. The paper does not establish the claimed links for bullying victimization or childhood trauma, or show that these experiences predict future psychotic experiences. (LLM, conf=0.86)

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.
