Abstract

This study explored prospectively the effects of dispositional and situational optimism on mood (N = 90) and immune changes (N = 50) among law students in their first semester of study. Optimism was associated with better mood, higher numbers of helper T cells, and higher natural killer cell cytotoxicity. Avoidance coping partially accounted for the relationship between optimism and mood. Among the immune parameters, mood partially accounted for the optimism-helper T cell relationship, and perceived stress partially accounted for the optimism-cytotoxicity relationship. Individual differences in expectancies, appraisal, and mood may be important in understanding psychological and immune responses to stress.

  • Because the social-engagement system is interconnected with autonomic regulation of the heart and lungs, engaging with the patient can promote a shift in sympathovagal balance-upregulation of vagal activity and downregulation of sympathetic activity-to a mind-body state of interpersonal connectedness and physiological calm.

    “Because the social-engagement system is interconnected with the autonomic regulation of the heart and lungs, the process of engaging with the patient (even in small ways through the use of gaze, tone of voice, or rhythm) can promote a concurrent shift in sympathovagal balance—upregulation of vagal activity and downregulation of sympathetic activity—to a mind-body state of interpersonal connected”

  • Interventions that facilitate reappraisal of threat expectancies, target imaginary rescripting of the trauma narrative, or induce optimism, compassion, hope, and expectancy may reduce arousal by downregulating the HPA axis, downregulating sympathetic activation, and modulating immune function adaptively.

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.
