Longitudinal Research

11.7K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

  • 医疗技术 医疗技术 医学技术
  • 数据科学数据科学数据科学

背景情况:

  • 视野 (VF) 测试对于诊断和监测眼睛疾病至关重要.
  • 准确测量VF变异性和可靠性对于临床决策至关重要.
  • 当前的方法可能无法有效地捕捉内在的测量变化.

研究的目的:

  • 预测视野 (VF) 结果中的内在测量变异性和可靠性.
  • 使用计算机模拟模型来预测VF数据丢失.
  • 为估计虚拟货币的可变性和可靠性建立关键时间框架.

主要方法:

  • 在20年 (长期) 和28天 (短期) 的时间里,模拟了10万名受试者,使用不同的VF测试频率.
  • 使用滚动窗口估计的可变性和可靠性,直到连续3次访问达到5%的门.
  • 根据连续的临床标准和与基准真相 (TgV,TgR) 的比较,评估变异性 (TcV) 和可靠性 (TcR) 的定义关键时间.

主要成果:

  • 强化短期VF测试 (每天1次测试) 在5天内确定可靠性和可变性.
  • 长期测试 (4次测试/一次访问,每月一次) 需要几年来估计变异性 (TCV的中位数为6年).
  • 估计的可变性和可靠性显示出临床上与基本事实存在很小的差异;可靠性是TcR/TgR的主要预测因素.

结论:

  • 在临床环境中,对VF可变性的纵向估计是不切实际的.
  • 密集的,短期的VF测试提供可靠的可变性和可靠性率高效.
  • 提供了一个框架来评估可变性对随着时间的推移检测VF变化的影响.
