The aim of this study is to examine the pre- and one year postoperative psychic functioning of a bariatric surgery patient using the Rorschach Test and the Thematic Perception Test (TAT). The sample of the study consists of a 47-year-old female participant diagnosed with obesity and applied to Başkent University Istanbul Hospital. The informed consent form was obtained. A psychoanalytic semistructured interview was conducted with the participant, and then the Rorschach Test and the TAT were administered in both application. The projective tests were analyzed and interpreted according to the French School. In the hypothesis of this study, it is thought that the psychic organization will not accompany the rapidly changing body with bariatric surgery. In both protocols of the patient, it is expected that such response contents are seen due to the lack of psychic envelope in obesity; depression and anxiety responses become evident in the content of the answers given to the cards in the posoperative tests, and the presence of anatomy responses are seen in both tests. In the findings, especially referring to identity, the V. Card in the Rorschach Test, and the 1, 3BM, 10, 12BG and 13B card responses in the TAT regarding coping with depressive position, loss and loneliness show that depressive affect increases after the surgery. In both tests, the excess of anatomy responses, the presence of tactile content show the anxiety and the the lack of pyschic envelope and describe the surgically changed body does not cause a differentiation in the psychic organization.
