Abstract

Skin conductance response (SCR) to emotion-evoking stimuli has in previous studies suggested the existence of two subgroups of schizophrenia patients. One is characterized by absent SCR and the other by heightened or non-habituating SCR. These subgroups have also been shown to differ in symptoms, prognosis and social integration. The present project compared social cognition in the two subgroups. SCR from 28 patients with schizophrenia and 24 matched healthy controls was measured while they watched emotion-evoking and neutral video tapes. Assessments of symptoms, neurocognition, social cognition, and social function were also performed. Event related potentials (ERP) were recorded in response to pictures of people experiencing pain or not. Subjects were divided into "SCR non-responder" and "SCR responder" groups based on SCR frequency. Schizophrenia SCR responders had significantly higher self-reported personal distress in response to others in distress and lower P300 ERP responses to others in pain than schizophrenia SCR non-responders and healthy controls. SCR responsiveness is a potential marker of subgroups of patients with schizophrenia that differ in pathophysiology, function and prognosis.

  • An earlier study found no significant difference in performance on the MATRICS battery between EDA responding and non-responding patients, and a trend approaching significance for better results among EDA non-responders.

    “These findings, however, contradict an earlier study that found no significant difference in performance on the MATRICS battery between EDA responding and non-responding patients, and a trend approaching significance for better results among EDA non-responders73.”

    From Autonomic nervous system dysfunction in schizophrenia: impact on cognitive and metabolic health (2021) · cites this paper as [73]

    Methods §2.2.2 identifies the neurocognitive measure as the MATRICS battery, and Results §3.2 reports no significant differences between the two schizophrenia SCR subgroups. The paper does not report a near-significant trend toward better MATRICS performance among non-responders; the trend-level result in Results §3.1 concerns the proportion of SCR non-responders among patients versus healthy controls, not battery performance.

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.
