In this research, empirical analysis of data from 200 couples in marital crisis, included in couple therapy treatment, reveals factors, both of onset and overcoming of marital crisis. It is argued that marital crisis is a phenomenon primarily linked to personality structure of actor and partner. Furthermore, on the basis of key dimensions of personality of actor and partner, it is possible to detect personality characteristics both for men and woman with good and poor treatment prognosis. Third, by detecting effectiveness and efficacy of psychotherapeutic techniques, two models of therapeutic approaches with highest efficacy are created. In the integration of results, it is suggested that two big factors of marital crisis and its overcoming exist and they are named Communication and Psychopathology.
