Garcia Adaptive Equilibrium Theory (GAET): A New Nursing Theory for Mental Health Nursing.

Mental health nursing demands a dynamic, patient-centered approach that goes beyond crisis intervention and symptom management. Traditional models like the Roy Adaptation Model and Tidal Model emphasize adaptation and recovery but fall short in capturing the fluid, nonlinear nature of mental health. The Garcia Adaptive Equilibrium Theory (GAET) introduces a new framework viewing mental health as a continuous balancing process. In this model, nurses serve as Equilibrium Facilitators, identifying points of instability and intervening early to prevent crises.Central to GAET is the Equilibrium Spectrum, which conceptualizes mental health as a fluctuating continuum-from stability to severe distress. Unlike traditional psychiatric approaches focused on reactive treatment, GAET incorporates Equilibrium Forecasting, a proactive assessment strategy that integrates subjective tools (scales, narratives) and objective data (biomarkers, physiologic signs) to anticipate deterioration.By reframing mental health care around real-time stabilization, GAET promotes early intervention, sustained well-being, and a shift toward preventive, holistic care. This theory redefines psychiatric nursing as an active, interdisciplinary practice focused on maintaining equilibrium rather than responding to disruption-empowering nurses to lead in mental health stabilization and prevention.
