Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Halo Effect01:27

Halo Effect

856
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

科学领域:

  • 医疗保健服务研究 医疗服务研究
  • 患者体验测量 患者体验测量
  • 心理测量 心理测量 心理测量

背景情况:

  • 像JSPPPE和WTPS这样的现有患者报告体验测量 (PREM) 显示出高度的相互关联和天花板效应,限制了它们捕捉细微患者体验的能力.
  • 在PREM中,上限效应会导致信息丢失,因为可能无法测量得分最高的患者之间的差异.
  • 开发具有更大的可变性和更低的上限效应的PREM对于准确评估患者体验和识别影响患者体验的因素至关重要.

研究的目的:

  • 从现有的PREM中识别和分组测量患者体验的相似方面的项目.
  • 使用项目响应理论开发一种新的,简短的PREM,具有较低的上限效应.
  • 为了验证新的PREM的因子结构,内部一致性和与已建立的PREM在不同的测量量级 (二进制与5点利克特) 上的相关性.

主要方法:

  • 两项涉及寻求肌肉骨护理的患者的横截面研究进行,以开发和验证新的PREM.
  • 探索性和确认性因子分析 (CFA) 用于确定项目分组,其次是项目响应理论来选择具有最佳难度参数的项目.
  • 新的PREM被评估使用二进制和五分利克特尺度,评估内部一致性 (克朗巴赫α) 和与其他PREM的相关性.

主要成果:

  • 确定了三个项目分组:"对临床医生的信任"",与临床医生的关系"",参与共享决策". "对临床医生的信任"因素被选为进一步开发.
  • 一个7项简短的形式 (TRECS-7) 显示出出色的CFA模型合适性,内部一致性 (Cronbach的α = 0.91),以及良好的项目响应理论参数,表明降低了天花板效应.
  • 验证队列证实了TRECS-7的性能,显示出良好的模型匹配,优秀的内部一致性 (Cronbach的α = 0.92),有限的天花板效应 (14%) 和与JSPPPE (ρ = 0.77) 和WTPS (ρ = 0.74) 的显著相关性.

结论:

  • 一个简短的,以信任为重点的7项患者体验测量 (TRECS) 有效地减轻了其他PREM中发现的常见上限效应,具有强烈的心理测量特性.
  • TRECS提供了对患者体验的更准确的评估,有助于评估干预措施并推动医疗保健系统的改进.
  • 未来的研究应该专注于在不同人群中对TRECS的外部验证以及基于人群的T分数转换表的开发.
