概括
随着时间的推移,密集纵向数据 (ILD) 收集的遵守程度会下降,尤其是在较长的研究中. 药物使用可能会影响酒精和大麻研究中的调查答案一致性和不合规性.
科学领域:
- 心理学 心理学 心理学
- 成研究 研究成研究
- 数据科学数据科学数据科学
背景情况:
- 密集的纵向数据 (ILD) 收集对于了解现实世界物质使用模式至关重要.
- 在ILD研究中,长时间的评估窗口对参与者合规性和响应一致性构成挑战.
- 关于影响ILD遵守和一致性的因素的先前研究是有限的.
研究的目的:
- 调查如何在漫长的ILD协议中随着时间的推移保持合规性和响应一致性.
- 检查事件和个人层面对大学生报告酒精和大麻联合使用的合规性和响应一致性的影响.
- 评估时间和测量冲击对违规和响应一致性的影响.
主要方法:
- 在多层次中断时间序列框架内利用线性混合效应模型.
- 分析了316名大学生参与两次28天的ILD爆发的数据,每次每天进行5次调查.
- 评估了不合规性 (错过的调查) 和响应的一致性 (饮酒报告中的差异).
主要成果:
- 时间与不遵守积极相关,这表明在研究持续时间内遵守程度下降.
- 不合规率在第二次测量爆发时增加.
- 时间和测量爆发都没有显著影响响应的一致性;然而,当天使用物质似乎影响了非响应和一致性.
结论:
- 在漫长的ILD协议中,参与者的服从性普遍下降,而响应的一致性保持稳定.
- 较短的评估窗口或适应性提示策略可能会提高研究合规性.
- 对日常负担和背景的进一步研究是必要的,以优化未来的ILD设计用于物质使用研究.

Longitudinal Research
11.9K
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...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Assumptions of Survival Analysis
114
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

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...

Crossover Experiments
2.7K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
