This book is concerned with the association between stress, control and the implication for strategic response. It aims both to provide an up-to-date account of research in the area of stress for the advanced student and to develop a new synthesis of ideas leading to a cognitive model of stress and illness. The book reflects the idea that responses to stressful conditions are likely to be strategic, designed in order to achieve control in different ways. Concepts such as responsibility, instrumentality and predictability are discussed in an attempt to make the relationship between stress and control explicit. Different forms of the exercise of control are identified as features of strategy.
