Objectives : The close relationship between impaired self-referential processing and intrinsic motivation in schizophrenia has beensuggested, but is not investigated yet. The purpose of this study was to explore the characteristics of self-referential processingand its relationship with intrinsic motivation in patients with schizophrenia. Methods : Nineteen patients with schizophrenia and 24 healthy controls performed a self-referential processing task, in which aface (self, familiar other, or unfamiliar other) and three words (positive, neutral, and negative nouns) were presented. Participantswere asked to indicate which word is relevant to the face. Intrinsic motivation and basic psychological needs affecting intrinsicmotivation were assessed using self-reports. Results : Compared to healthy controls, the relevance rating between self-face and neutral word was significantly lower in patientswith schizophrenia (p=0.02). In patients with schizophrenia, it was negatively correlated with intrinsic motivation (r=-0.47, p=0.04)and competence (r=-0.47, p=0.05) which is known to influence intrinsic motivation. Conclusion : These results suggest that there is an impairment in self-referential processing in schizophrenia and it is associatedwith an impairment in intrinsic motivation. In particular, amotivation in patients with schizophrenia may represent a facet of selfdisorder.
