From the author: E. Bern's clients argued that group therapy for married couples is the most important invention in the history of mankind after the invention of the wheel. E. Berne believed that the best form of therapy for couples is group therapy. The founder of Transactional Analysis (TA) had his own compelling arguments for this. In one of his books, he quotes members of a group for married couples as saying that such groups are “the greatest invention since the wheel.” (Bern E. Transactional analysis in psychotherapy, 2001; p. 248). E. Berne himself, assessing the experience of the group for married couples, writes that it “was the most inspiring experience in the entire psychiatric career of the author.” (Bern E. Transactional analysis in psychotherapy, 2001; p. 247). Analyzing the dynamics of a marital therapy group, E. Berne notes that first of all, the three most common marital games must be destroyed - "The Court Room", "Honey", and "Besides". As these games-at-the-therapy-appointment reveal their inconsistency in the group, the group can move on to analyzing home games, such as “Harried Housewife”, “If It Weren’t For You”, “Disgrace”, etc. if these games manages to destroy, previously hidden sexual difficulties of the spouses are revealed, and, as Bern writes, then “therapy can already be carried out in generally accepted ways” (Group psychotherapy, 2000; p. 382) It can be assumed that at the initial stage of play-at-reception therapy -therapists perform the function of protecting the existing state of affairs and are, in fact, a form of resistance. giving up these games means that the group has reached a level of trust and security that allows them to work “with what they have.” In classical TA, an important condition for refusing games is building up the potential of the Adult, freeing the adult from the prejudices of the Parent and the illusions of the Child. in other words, the development of a person’s ability to understand ego states and make a conscious choice of behavior and response in a specific situation. We observe the full effects of decontamination (i.e., the liberation of an adult from illusions and prejudices) in a film therapy group for married couples. There is no need to describe the results of our research in full here; that would take up too much space. To be brief, using the “Choice of Words” technique, developed by V.A. Petrovsky, we assessed changes in the ego structure of the participants by comparing the test results obtained at the beginning and at the end of the group’s work. Data processing showed significant growth in Adult in 80% and Natural Child in 40% of participants. But perhaps even more than the results of test measurements, we are inspired by the subjective assessments of the group’s effectiveness expressed by its participants three months after completion of the work. All (!) married couples noted changes in their lives and an increase in marital satisfaction. Here are some of the most typical statements from reflective reports. - We started talking to each other more. - We spend more time together. - I learned to understand my husband better. “We started watching films together and discussing what we saw. In my opinion, such statements indicate an improvement in communication in a couple, as well as the restoration of the function of joint leisure. The conclusion about the increased functionality of the couple is confirmed by the results of a survey of participants using a questionnaire on marital satisfaction. We believe that the discussed effects of film therapy for couples are directly related to the characteristics of film therapy as a method. When discussing a film, we ask participants to talk not only about “what I saw,” but also about “how I saw it.” This method structure allows participants.
