Psychosocial modifiers of response to stress

The impact of stress upon an organism is far more complex than the simple design of most stress research implies. We offer an expanded model for studying the relation of stressors to pathological outcomes, which takes into account both the adaptive capacity of the organism before the stressor occurs and the defenses marshalled in response to the stressor. The model also distinguishes among the initial responses of alarm, sustained defensive behaviors, and the relatively irreversible endstates which remain after resistance has ended. Realizing that only a multidiscomplinary approach can begin to capture the wholeness of human experience, this research paradigm anticipates that stressors, adaptive capacities, defenses, alarm reactions, and pathologial end-states will take place at the biological, psychological, interpersonal and sociocultural levels simultaneously and successively. Data on life change stress and psychological health outcomes gathered as part of the Air Traffic Controller Health Change Study are analyzed to illustrate the use of the model in identifying psychosocial and biological modifiers of response to stress.
