Objectives Decision-making in patients with schizophrenia has been known to be inefficient in both cognitive and affective aspects. The purpose of this study was to investigate the influence of anhedonia and self-esteem on the decision-making process in schizophrenia. Methods Twenty patients with sc...

조현병 환자들이 내리는 의사결정은 어떤 특징을 가지는가 | 1)2) 조현병 환자들에서 흔히 보이는 기능저하가 이러한 의사결정과정의 문제에 기인하는 것으로 제시되어 왔다.3) 조현병 환자들이 내리는 의사결정은 충동적인 성격을 띈다.4-8) 조현병 환자들은 결정을 실행에 옮기기까지 더 많은 시간을 소모하지만,7) 가능성 추론에서 결론을 도출하기까지 정보 수집을 덜하는 경향이다. | |
의사결정이란 무엇인가 | 가능한 여러 선택지 중에 선호도를 형성하고, 이에 따라 어떤 행동을 취할지 선별하여 실행에 옮기며, 결과를 예측하는 일련의 과정을 의사결정(decision-making)이라 지칭한다.1)2) 조현병 환자들에서 흔히 보이는 기능저하가 이러한 의사결정과정의 문제에 기인하는 것으로 제시되어 왔다. | |
의사결정에서 정서적인 요소가 영향을 미치는 예시에는 어떤 것이 있는가 | 16-18) 따라서 무쾌감증은 보상회로의 기능장애에서 비롯되는 증상일 것이라고 생각되나, 아직까지 삶의 질과 밀접하게 관련이 있는 일상생활의 의사결정과 관련된 보상에 있어 뇌의 어떠한 부위가 관련되는지에 대해서는 알려진 바가 없다. 조현병 환자가 어떤 물건을 구매하는 경우, 물건 구매를 통해 얻는 즐거움을 무쾌감증으로 인해 느끼지 못한다면, 굳이 그 물건을 구입할 필요를 느끼지 못할 것이므로, 해당 물품이 주는 즐거움을 저평가하여 구매 결정으로 이어질 가능성이 정상인에 비해 더 낮을 것이다. |
