概括
生态瞬间评估 (EMA) 研究的参与者有时会延迟调查反应,特别是在体力活动期间. 这项研究发现,虽然延迟不会影响报告的活动水平,但它们引入了轻微的随机错误.
科学领域:
- 行为科学是一种行为科学.
- 健康研究方法的方法论.
背景情况:
- 延迟反应在生态瞬间评估 (EMA) 中很常见.
- 这些延迟对数据质量和潜在的选择偏差的影响尚不清楚.
研究的目的:
- 调查EMA的响应延迟是否引入了选择偏差.
- 评估反应延迟对自我报告的身体活动准确性的影响.
主要方法:
- 339名参与者每天五次使用EMA,持续7天,以报告身体活动.
- 与此同时,使用可穿戴显示器收集了客观的体育活动数据.
- 欧洲药物管理局的回复和活动监测数据被比较,以评估延迟报告带来的偏差.
主要成果:
- 参与者更有可能在较高的体力活动期间延迟EMA反应.
- 当参与者处于不那么活跃的状态时,反应延迟发生.
- 由于延迟,报告活动水平没有发现系统偏差,但随机错误略有增加.
结论:
- 受访者似乎根据活动水平自行选择报告时刻.
- 欧洲药物管理局的短暂响应延迟不会显著影响数据质量.
- 调查结果表明,尽管常见的响应延迟,EMA数据仍然可靠.

Bias in Epidemiological Studies
148
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Naturalistic Observations
15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Bias

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...
