背景：动机缺陷被认为是精神分裂症的核心特征，近年来的研究开始揭示精神分裂症患者动机缺陷的生物学和心理特征及机制。本研究的目的是使用一般因果关系取向量表（GCOS）调查精神分裂症患者的动机特征，以及动机取向对精神分裂症患者功能结果的影响。方法：本研究共招募了53名门诊精神分裂症患者和38名健康对照者。 GCOS用于评估三种不同动机取向的个人倾向：自主性、受控性和非个人性取向，分别对应于内在动机、外在动机和无动机。还评估了受试者的认知功能、精神症状、社会功能和生活质量。结果：患者组自主定向得分显着低于对照组，而其他两项定向得分两组间无显着差异。自主取向与各种临床变量相关，回归分析被认为是社会功能预测准确度最高的变量之一。结论：精神分裂症患者的GCOS测量的内在动机显着低于健康对照。内在动机的缺陷与临床特征广泛相关，并且是社会功能的决定因素。开发增强内在动机的治疗方法对于精神分裂症患者的功能恢复至关重要。© 2015 Elsevier Inc. 保留所有权利。
Background: Deficits of motivation have been considered to be a core feature of schizophrenia, and recent studies have begun to reveal the biological and psychological characteristics and mechanisms underlying the deficits in motivation in schizophrenia patients. The aims of the present study were to investigate the characteristics of motivation in schizophrenia patients using the General Causality Orientations Scale (GCOS), and the impacts of motivational orientations on the functional outcomes in schizophrenia patients. Methods: A total of 53 outpatients with schizophrenia and 38 healthy controls were recruited for this study. The GCOS was used to assess individual tendencies in respect of three different motivational orientations: the autonomy, controlled, and impersonal orientations, corresponding to intrinsic motivation, extrinsic motivation, and amotivation, respectively. The cognitive functioning, psychiatric symptoms, social functioning, and quality of life of the subjects were also assessed. Results: The score for autonomy orientation was significantly lower in the patient group than that in the control group, while no significant differences were found between the two groups in respect of the scores for the other two orientations. The autonomy orientation was associated with various clinical variables, and regression analysis identified as one of the variables with the highest predictive accuracy for social functioning.Conclusions: Intrinsic motivation measured by the GCOS in schizophrenia patients was significantly lower than that in healthy controls. The deficits of intrinsic motivation were broadly associated with the clinical features and were a determinant of social functioning. Development of treatments for enhancing intrinsic motivation would be essential for functional recovery in schizophrenia patients.© 2015 Elsevier Inc. All rights reserved.
