What is the Origin of Stress Resilience Quotient?

This term synthesizes concepts from psychoneuroendocrinology and allostatic load theory. The quotient format provides a standardized, easily interpretable measure of resilience, moving beyond single-point stress hormone measurements. It aims to capture the system's dynamic response capability.

What is the Mechanism of Stress Resilience Quotient?

The SRQ is often derived from analyzing the diurnal cortisol curve amplitude, Heart Rate Variability (HRV) patterns, and the speed of recovery following a standardized laboratory stressor. High resilience correlates with a steep cortisol awakening response followed by efficient negative feedback leading to rapid decline. Low SRQ suggests allostatic overload, where chronic sympathetic activation depletes adaptive resources and impairs subsequent hormonal regulation.

Stress Resilience Quotient

Meaning

A composite metric quantifying an individual’s inherent capacity to maintain physiological and psychological homeostasis in the face of acute or chronic stressors, reflecting the efficiency of the HPA axis and autonomic nervous system adaptation. A high quotient suggests robust buffering capacity against endocrine disruption. It is a measure of systemic fortitude.
