Key result
Group identity disidentification lowers systolic blood pressure reactivity during acute stress vs controls.
Why the study?
While social identities are linked to cardiac regulation under stress, the physiological effects of disidentification on cardiovascular stress responses remained unknown.
Does disidentification reduce cardiovascular reactivity to acute social evaluative stress in healthy adults?
RCT (n=113)
Randomized
Does disidentification reduce cardiovascular reactivity to acute social evaluative stress in healthy adults?
Active disengagement from a group identity (disidentification) blunts systolic blood pressure reactivity to acute social stress in healthy adults.

Disidentification blunts SBP reactivity to acute social stress; extends social identity research to cardiovascular stress responses.
Lashkay et al. (2026) conducted an RCT in Healthy adults (n=113). Disidentification (from university student identity) vs. Control condition was evaluated on Cardiovascular reactivity (systolic and diastolic blood pressure and heart rate). Disidentification from a group identity led to significantly lower systolic blood pressure reactivity during acute social evaluative stress compared to controls.
