PROACTA - A WAY TO STUDY THE TENDENCY TO OCCUR (TTO) OF PATIENT BEHAVIORS

Classical decision theory formulas have been combined with more recent theories from psyche-social origins (such as Rosenstock's health beli ef model, Fisbein's rational action theory, Bandura's concept of self- efficacy, Triandis' concern for the assessment of habits, etc.). A sof tware, called PROACTA, enables simulations of actual cases. Currently, it is being tested in various backgrounds. It is orientated in order to help conceive intervening strategies, especially in the area of pat ient education. Examples of a case study are presented.
