概括
30天的时间线追溯 (TLFB) 窗口足以评估年轻人的酒精使用模式. 这种较短的报告期捕获了与较长时间窗口相比较的数据,减少了参与者和员工的负担.
科学领域:
- 青少年健康 青少年健康
- 药物使用研究研究.
- 心理评估 心理评估
背景情况:
- 青少年的酒精使用模式表现出变化,往往需要在研究中延长报告期.
- 较长的时间线追踪 (TLFB) 窗口,虽然全面,但增加了参与者和研究人员的负担.
- 这项研究研究了较短的TLFB窗口对青少年酒精使用评估的有效性.
研究的目的:
- 评估30天TLFB窗口的充分性,以捕捉青年酒精消费模式.
- 为了比较两个连续30天的酒精使用数据 (第1-30天和第31-60天).
- 为青少年酒精使用研究的未来研究方案的设计提供信息.
主要方法:
- 使用修改后的TLFB来评估481名参与者 (15-25岁) 在60天内的酒精消耗.
- 收集了关于饮酒总量,饮酒日和狂饮饮酒日的数据,分为两个30天间隔.
- 采用斯皮尔曼相关性,威尔科克森签名等级测试和类内相关性 (ICC) 来对子组进行分析.
主要成果:
- 所有测量的酒精结果在两个30天报告窗口之间都有显著的相关性 (p < 0.001).
- 在最近的30天期间 (1-30天) 饮酒量普遍较高,但差异很小,临床上相似.
- 类内相关系数表明报告窗口之间的可靠性中等至良好.
结论:
- 30天的TLFB报告窗口足以评估青少年的酒精使用.
- 这个较短的窗口提供了可比和可接受的自我报告的酒精使用数据.
- 使用30天的TLFB窗口有效地减少了参与者和研究负担.

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...

01:15Assumptions of Survival Analysis
391
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.

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...

12.3K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
