An investigation of the dyadic relationships between the client and the therapist in psychotherapy according to the control mastery theory in the context of therapeutic allience, positive-negative emotions and pathogenic beliefs

Control Mastery Theory (CMT) is a relational, cognitive, and dynamic theory that explains, regarding psychopathology and psychotherapy, how clients' activities in psychotherapy are organized according to their search for security, and provides individual formulation and includes mental functionality. The theory also has a structure that clarifies the treatment process for the therapist and guides the therapist's interventions. This research has empirically shown what kind of change and transformation occurs in the client's pathogenic beliefs by using the Actor-Partner Interdependence Model (APIM) analysis of the mutual negative-positive emotions of the client and the therapist and the therapeutic alliance levels they formed in the session. In the context of KUT, the research was conducted with Duration-Limited Dynamic Psychotherapy (SSDP), from the first 24 sessions of 31 clients, for a total of 284 session hours. In addition to all session averages, the first, third, eighth and last sessions were evaluated with APIM analysis. Additionally, repeated measurements were made between the therapist and the client. The research focused on the mutual relationship between the negative and positive emotions of the client and therapist in the session and the therapeutic alliance between the client and therapist. In addition, the change in the client's pathogenic beliefs was demonstrated through repeated measurements in the first and last sessions. Clients' pathogenic beliefs were examined with the Young Schema Scale, and it was tested whether the clients met their session goals. In the session measurements where the level of Therapeutic Alliance was evaluated, it was found that the therapeutic alliance was mostly realized in the 8th session. Moreover, by measuring the dyadic positive and negative emotions of the client and therapist, the changes at the emotional level between the therapist and the client during the sessions were examined. Young Schema Scale, PANAS Positive Negative Emotion Scale, Therapeutic Relationship Scale Client and Therapist form were used as scales.
