[The strategy and contemporary subjects of research in psychotherapy]

By the means of the research of the psychotherapy we can obtain objective and reliable informations that help us to decrease the risk of the subjective distortion, to control the influence of the chance events and to find the connections otherwise not observed. We use several types of research strategies: a qualitative or quantitative strategy, intensive, extensive, multi-variational strategy etc. The contemporary research deals with the effectiveness of the therapy, the indication and the psychotherapeutical process. It was found out that the therapy by the psychological means is demonstrably more effective than the placebo therapy or no therapy, and using various methods we induce qualitatively different changes. That is why the differential approach is necessary; this approach leads in the theory towards progressive integration and towards forming the general model of the psychotherapy.
