Depression, Anxiety and Stress Management

In the present study we introduce a new stress approach, which completes the transactional theory of Folkman and Lazarus (1984). It is a numerical model in which we consider another variable named PSS (Previous State of Stress) that we estimate necessary to explain why psychological state of stress occurs or not. In our model, stress is presented in the form of a mathematical equation of three variables (PSS, SV, and R). By evaluating each of these components, this equation enables us to evaluate the generated stress intensity of a person. By improving this formula, the present model enables us to consider another type of stimulus (positive stimulus) and to evaluate it. Many instances of daily stress, that takes into account these new dimensions, have been cited. The stress formula efficiency has been tested by applying it on these examples and to some concepts like violence and stress accumulation. RQSI (Required Quantity of Stress Index) is an index that we have introduced in our numerical model. The calculated RQSI enables us to evaluate the average amount of stress (positive or negative) that a person receives from each stimulus he has been exposed to during a period. A new definition of stress phenomena, based on our new numerical data model, is proposed.
