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...

Comparing Experimental Results: Student's t-Test

5.8K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

  • 数字健康数字健康
  • 职业健康 职业健康 职业健康

背景情况:

  • 移动健康应用程序在打击身体不活动方面表现有前途.
  • 关于它们在工作场所绩效反方面的有效性的证据有限.
  • 本研究通过评估基于移动应用程序的性能反干预来解决这一差距.

研究的目的:

  • 评估基于移动应用程序的绩效反 (MABPF) 对体力活动 (PA) 水平和久坐时间 (ST) 的影响.
  • 为了比较MABPF在大学员工群体中每小时提醒和没有提醒的有效性.
  • 评估MABPF在工作场所环境中促进PA的潜力.

主要方法:

  • 一个为期12周的随机对照试验,涉及150名大学工作人员.
  • 三组:每小时提醒的MABPF,只有MABPF,和一个对照组.
  • 使用国际体力活动问卷-简单表格,计步器和谷歌Fit进行评估的PA和ST.

主要成果:

  • 两个MABPF组都在PA指标 (步数,步行得分,中度至强度PA) 中显著改善,并减少了ST.
  • 带有每小时提醒的MABPF在增加步数方面比单独的MABPF更有效.
  • 与对照组相比,每小时提醒的MABPF也导致了明显更大的ST减少.

结论:

  • 特别是在每小时提醒的MABPF干预措施有效地改善了PA行为,并减少了大学工作人员的ST.
  • 这些发现强调了基于理论的移动健康干预措施在工作场所促进PA的有用性.
  • 该研究支持将MABPF纳入职业健康战略.
