Purpose To investigate differences in motivation between patients with schizophrenia and healthy controls using the General Causality of Orientation Scale (GCOS) and to reveal the relationships between motivation, social anxiety, psychiatric symptoms, and social functioning in the patients. Methods Twenty two outpatients (12 men; mean age 31.7 years) and 22 controls (12 men; mean age 33.0 years) were recruited. The GCOS was used to evaluate the strength of three different orientations of motivation (Autonomy: A; Controlled: C; Impersonal: I). Orientations A, C, and I correspond to concepts of intrinsic motivation, extrinsic motivation, and a tendency to lose motivation, respectively. The Positive and Negative Syndrome Scale (PANSS), the Scale for the assessment of negative symptoms (SANS), the Liebowitz Social Anxiety Scale (LSAS-J), the Japanese version of the Social Functioning Scale (SFS-J), the Clinical Global Impression of Cognition (CGI) were used to assess the patients symptom, social and global functioning. The institutional review board approved the protocol. Results There were no significant differences on the GCOS subscales between patients and controls. Regarding the correlations between the GCOS and psychiatric symptoms, social and global functioning in the patients, the scores for A was significantly correlated with PANSS, SANS, and SFS-J. The scores for C was significantly correlated with PANSS, SANS, and SFS-J. The score for I was significantly correlated with PANSS, SANS, LSAS-J, and CGI. Conclusion Although we didnt find differences in motivation between patients and controls, patients motivation was correlated with social anxiety as well as psychiatric symptoms and social functioning.
