The role of activity in anticipating and confronting stressful situations.

This paper is an analytical review of studies comparing stress reactions in threatening situations during which the person can or cannot take action. The studies reviewed were conducted mainly in real-life situations and involved diverse forms of coping activities under various conditions of danger and distress. To achieve a better understanding of the effect of activity on stress reactions, several distinctions are made: between various types of stress reactions; between various indices and measurements of stress reactions; between activity which is directly related to the source of threat and activity which is not; and between various personality dimensions. The adaptive potential of activity in stressful situations is discussed in terms of: the sense of mastery and control provided by activity; activity as a means of attention diversion; and activity as a means of discharging energy generated by mobilization. It is suggested that taking action under stressful conditions, as opposed to remaining passive, is a powerful coping tool.
