概括
这项研究评估了精神分裂症认知评分表 (SCoRS) 来衡量精神分裂症的认知障碍. 基于SCoRS的实用程序有效地捕捉了与认知功能相关的生活质量变化,与通用措施不同.
科学领域:
- 精神病学是一个精神病学.
- 卫生经济学 卫生经济学
- 心理测量 心理测量 心理测量
背景情况:
- 认知功能障碍是精神分裂症的核心症状,严重影响生活质量.
- 现有的通用与健康相关的生活质量指标,如EQ-5D,不足以检测精神分裂症的认知变化.
- 需要专门针对精神分裂症的措施来评估认知障碍及其对生活质量的影响.
研究的目的:
- 评估精神分裂症认知评分表 (SCoRS),这是一个旨在测量精神分裂症认知障碍的工具.
- 为公用事业估值开发基于SCoRS关键项目的健康状况图片.
- 将基于SCoRS的公用事业与EQ-5D公用事业在捕捉生活质量变化的性能进行比较.
主要方法:
- 使用专家意见和心理测量分析来选择5个关键的SCoRS项目 (注意力,学习,处理速度,社会认知,记忆).
- 从这些项目创建了健康状况图片,并使用复合时间权衡 (cTTO) 方法对400名受访者进行估值.
- 用计量经济学模型来估计不实用性,并将基于SCoRS的公用事业与EQ-5D公用事业进行了比较.
主要成果:
- 估值研究给出了健康状态的实用值,最佳状态为0.855,最差状态为0.152.
- 严重的社会认知,学习和记忆障碍导致了最大的无用性.

01:30Negative and Cognitive Symptoms of Schizophrenia
96
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...
