title: The mediating effects of psychophysiological reactivity and recovery on the relationship between environmental stress and illness.
abstract: The present study investigated the association between psychophysiological reactivity and recovery and physical and psychological symptoms both directly and interactively with environmental stress. Symptoms, environmental stress, and psychophysiological reactivity to and recovery from a laboratory stressor were measured in 50 subjects. As in previous research, the results indicated a significant relationship between environmental stress and symptoms of illness. Although the data did not support a direct relationship between psychophysiological activity and illness, support for a buffering effect was found. Those individuals with greater physiological arousal to or slower recovery from a laboratory stressor exhibited a stronger relationship between environmental stress and symptoms than those who were less reactive or faster to recover. Implications of these results were discussed in the context of theoretical models relating stress and illness.
