Understanding depressive symptoms through psychological traits and physiological stress reactivity

Depressive symptoms and attenuated physiological reactivity to laboratory stressors.

There is evidence that depressive symptoms are associated with attenuated physiological reactivity to active stressors. However, it is not known whether blunted reactivity in depressed individuals is stressor-specific. We examined cardiovascular and electrodermal reactivity in non-clinical participants with varying levels of depressive symptoms to different active and passive stressors. Depress...

The Relationship of Psychological Variables and Physiological Reactivity to Psychological Stress in Coronary Artery Disease Patients

Oxytocin receptor gene and depressive symptoms associated with physiological reactivity to infant crying.

Both the oxytocin receptor (OXTR) gene and depressive symptoms have been associated with parenting behaviour. The OXTR GG genotype has been suggested to be related to more sensitive parenting, whereas depressive symptoms may affect sensitivity negatively. We examined the role of OXTR and the influence of depressive symptoms in explaining differences in physiological reactivity to infant crying....

We hypothesized that certain stressful events would mediate the relationship between gender and depressive symptoms. We also hypothesized that individual differences in emotional reactivity would ...
