Key result
Availability of functional support significantly lowered heart rate reactivity to acute stress in participants with low perceived network support compared to those with high support (p=0.04).
Why the study?
Does the availability of functional support reduce blood pressure and heart rate reactivity to acute stress?
Does the availability of functional support reduce blood pressure and heart rate reactivity to acute stress?
p-value: p=0.04
The availability of functional support modulates physiological reactivity to acute stress, with effects depending on an individual's baseline perceived network support.
May buffer HR reactivity in low-support individuals; hypothesis-generating and requires prospective confirmation before clinical consideration.
Social support is associated with lower cardiovascular disease risk. We examined the effects of perceived network support and availability of functional support in the laboratory on blood pressure and heart rate (HR) reactivity to acute stress. When functional support was available, participants with low perceived network support had significantly lower HR reactivity than participants with high perceived network support (p = .04). Conversely, when functional support was not available, participants with low perceived network support had significantly higher HR reactivity (p = .05). Self-reported anxiety post-stressor was significantly higher when functional support was not mentioned (p = .03).

O’Donovan et al. (2008) studied this question. Availability of functional support vs. No functional support available was evaluated on Heart rate (HR) reactivity to acute stress (p=0.04). Availability of functional support significantly lowered heart rate reactivity to acute stress in participants with low perceived network support compared to those with high support (p=0.04).
