本项目的目标是评估精神分裂症患者内在动机的主观报告及其与认知功能、情绪和人格的关系。采用动机特质问卷，考察了内在动机的3个组成部分(个人掌握、竞争优势、与焦虑相关的动机)。他们还检查了流动智力、背景处理和工作记忆，以及与动机相关的情绪和个人特征的自我报告。参与者是66名精神分裂症或分裂情感障碍患者和44名健康对照。在对照组和精神分裂症患者中，自我报告的个人掌握能力和竞争优势没有区别，尽管患者确实报告了与焦虑相关的显著更高的动机。在对照组中，而不是患者中，自我报告的内在动机与认知表现密切相关。相比之下，对照组和患者在内在动机的自我报告与情绪和个性的相关测量之间显示出类似的强烈关系。这些结果与精神分裂症动机缺陷反映内在动机障碍的假设不一致。然而，他们确实表明，精神分裂症患者自我报告内在动机和认知功能之间的正常关系被打乱了。
The goal of the current project was to assess subjective reports of intrinsic motivation and their relationship to cognitive function, mood, and personality in schizophrenia. The authors used the Motivational Trait Questionnaire to examine 3 components of intrinsic motivation (personal mastery, competitive excellence, motivation related to anxiety). They also examined fluid intelligence, context processing, and working memory, as well as self-reports of mood and personal traits related to motivation. Participants were 66 individuals with schizophrenia or schizoaffective disorder and 44 healthy controls. Self-reports of personal mastery and competitive excellence did not differ between controls and individuals with schizophrenia, though patients did report significantly higher motivation related to anxiety. Among controls, but not patients, self-reports of intrinsic motivation were strongly related to cognitive performance. In contrast, both controls and patients showed similar strong relationships between self-reports of intrinsic motivation and related measures of mood and personality. These results are not consistent with the hypothesis that motivational deficits in schizophrenia reflect impairments in intrinsic motivation. However, they do suggest that the normal relationship between self-reports of intrinsic motivation and cognitive function is disrupted in schizophrenia.
