Abstract

Background A large body of research has examined the acute effects of intranasal oxytocin administration on social cognition and stress-regulation. While progress has been made with respect to understanding the effect of oxytocin administration on social cognition in clinical populations (e.g. autism, schizophrenia), less is known about its impact on the functioning of the hypothalamic-pituitary-adrenal (HPA) axis among individuals with a mental disorder.Method We conducted a meta-analysis on the acute effect of intranasal oxytocin administration on the cortisol response to laboratory tasks. The search yielded eighteen studies employing a randomized, placebo-controlled design (k=18, N=675). Random-effects models and moderator analyses were performed using the metafor package for the statistical program R.Results The overall effect size estimate was modest and not statistically significant (Hedges g=-0.151, p=0.11) with moderate heterogeneity in this effect across studies (I(2)=31%). Controlling for baseline differences in cortisol concentrations, moderation analyses revealed that this effect was larger in response to challenging laboratory tasks that produced a robust stimulation of the HPA-axis (Hedges g=-0.433, 95% CI[-0.841, -0.025]), and in clinical populations relative to healthy controls (Hedges g=-0.742, 95% CI[-1.405, -0.078]).Conclusion Overall, oxytocin administration showed greater attenuation of the cortisol response to laboratory tasks that strongly activated the HPA-axis, relative to tasks that did not. The effect was more robust among clinical populations, suggesting possible increased sensitivity to oxytocin among those with a clinical diagnosis and concomitant social difficulties. These data support the view that oxytocin may play an important role in HPA dysfunction associated with psychopathology.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Oxytocin administration may modulate glucocorticoid and autonomic stress reactivity, dampen anxiety and neural threat processing, and beneficially impact socioemotional processes and prosocial behavior.

    “Accumulating evidence from studies in animals and in healthy and psychiatric human populations shows that oxytocin administration may modulate glucocorticoid (16) and autonomic stress reactivity (17), dampen anxiety and neural threat processing (18,19), and beneficially impact socioemotional processes and prosocial behavior (20,21) [but see also (22,23) for seemingly nonprosocial effects].”
  • Intranasal oxytocin seems to only exert beneficial effects in individuals with suboptimal functioning in domains affected by oxytocin.

    “Intranasal oxytocin seems to only exert beneficial effects in individuals with suboptimal functioning in domains affected by oxytocin (16,32,65), although a solid neurobiological basis for this hypothesis is still lacking.”
  • The presence and severity of psychiatric symptoms moderates central and peripheral effects of oxytocin administration.

    “the observation that oxytocin administration had differential effects dependent on acute PTSD symptom severity adds to a growing body of literature indicating that the presence and severity of psychiatric symptoms moderates central and peripheral effects of oxytocin administration (16,64).”
  • A recent meta-analysis found that a single dose of intranasal oxytocin lowered cortisol in clinical populations characterised by dysregulation of the HPA axis, but did not significantly influence the cortisol response to stressful stimuli in healthy individuals.

    “For example a recent meta-analysis found that a single dose of intranasal oxytocin lowered cortisol in clinical populations characterised by dysregulation of the HPA axis, but did not significantly influence the cortisol response to stressful stimuli in healthy individuals (Cardoso et al., 2014).”
  • A previous meta-analysis found that a single dose of oxytocin reduced the cortisol response to stressful stimuli among clinical populations.

    “Indeed, a previous meta-analysis found that a single dose of oxytocin reduced the cortisol response to stressful stimuli among clinical populations (Cardoso et al., 2014).”

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.
