Negative symptoms and depression persist in one third of patients with schizophrenia. Previous studies suggested that depression has more impact on self-perceived compared to observer-rated social functions. Reduced emotional experience, a subdomain of negative symptoms, predicts social functioning deficits, although its role in self-assessment is unclear. We examined depression and reduced emotional experience and self-reports and informant ratings of social functioning and social cognitive abilities in 135 patients with schizophrenia. Discrepancies between sources were used to index the accuracy and bias in self-assessment. Less severe depression was associated with self-reports of reduced impairments in social functioning and better social cognitive abilities. Reduced emotional experience was related to informant ratings and self-reports of social functioning. Neither reduced emotional experience nor depression was correlated with discrepancies between sources, despite the bias of patients with lower depression to report that they were higher functioning and more competent. These findings suggest that patients with schizophrenia make global judgments about functioning based on current mood states. There was minimal association between the depression severity and the accuracy of self-assessment, despite positive biases associated with lower depression severity. The determinants of accuracy and bias in self-assessment requires more detailed examination and subdivision of patients based on their depression.

精神分裂症的抑郁症和情感体验减少:与自我报告且知情的日常社交功能的相关性

三分之一的精神分裂症患者持续出现阴性症状和抑郁。先前的研究表明,与观察者评价的社会功能相比,抑郁症对自我感知的影响更大。情绪体验降低是负面症状的一部分,预示着社交功能缺陷,尽管其在自我评估中的作用尚不清楚。我们检查了135名精神分裂症患者的抑郁症和情绪降低,自我报告以及对社交功能和社交认知能力的知情评级。来源之间的差异被用来索引自我评估的准确性和偏倚。严重程度较轻的抑郁症与自我报告的社交功能受损减少和社交认知能力提高有关。情感体验的下降与线人的评价和社交功能的自我报告有关。情绪低落和抑郁都与来源之间的差异无关,尽管抑郁低下的患者偏向于报告他们的功能更高,能力更强。这些发现表明,精神分裂症患者根据当前的情绪状态对功能进行整体判断。抑郁症严重程度与自我评估的准确性之间的关联最小,尽管与抑郁症严重程度较低相关的积极偏见。自我评估的准确性和偏误的决定因素需要根据患者的抑郁状况进行更详细的检查和细分。情绪低落和抑郁都与来源之间的差异无关,尽管抑郁程度较低的患者偏向于报告他们的功能更高,能力更强。这些发现表明,精神分裂症患者根据当前的情绪状态对功能进行整体判断。抑郁症严重程度与自我评估的准确性之间的关联最小,尽管与抑郁症严重程度较低相关的积极偏见。自我评估的准确性和偏误的决定因素需要根据患者的抑郁状况进行更详细的检查和细分。情绪低落和抑郁都与来源之间的差异无关,尽管抑郁低下的患者偏向于报告他们的功能更高,能力更强。这些发现表明,精神分裂症患者根据当前的情绪状态对功能进行整体判断。抑郁症严重程度与自我评估的准确性之间的关联最小,尽管与抑郁症严重程度较低相关的积极偏见。自我评估的准确性和偏误的决定因素需要根据患者的抑郁状况进行更详细的检查和细分。这些发现表明,精神分裂症患者根据当前的情绪状态对功能进行整体判断。抑郁症严重程度与自我评估的准确性之间的关联最小,尽管与抑郁症严重程度较低相关的积极偏见。自我评估的准确性和偏误的决定因素需要根据患者的抑郁状况进行更详细的检查和细分。这些发现表明,精神分裂症患者根据当前的情绪状态对功能进行整体判断。抑郁症严重程度与自我评估的准确性之间的关联最小,尽管与抑郁症严重程度较低相关的积极偏见。自我评估的准确性和偏误的决定因素需要根据患者的抑郁状况进行更详细的检查和细分。
