概括
记忆和日常运作的信息评估通常与客观措施保持一致. 然而,这些报告的可靠性随着告密者与个人之间的联系越来越频繁而显著增加.
科学领域:
- 老年学是指老年学的学科.
- 认知科学 认知科学
- 心理测量 心理测量 心理测量
背景情况:
- 临床医生和研究人员经常依靠信息员报告来评估认知变化.
- 告密者评估与客观认知措施之间的一致性仍然是调查领域.
研究的目的:
- 评估信息人报告的记忆和日常功能变化以及客观测量的结果之间的对应性.
- 确定告密者接触频率对这些评估可靠性的影响.
主要方法:
- 利用了来自美国健康与退休研究协同认知评估协议 (HCAP) 的2710名参与者及其信息人的数据.
- 采用了概括估计方程来比较10年来告密者报告与延迟单词回忆和日常生活工具活动 (iADL) 的前性测量.
- 研究了告密者接触频率对报告和测量变化之间的关联的相互作用效应.
主要成果:
- 举报人报告的记忆力下降与客观测量的单词回忆力下降相关.
- 在日常生活中的工具性活动 (iADL) 中,告密者识别的损失与实际的iADL下降相对应.
- 告密者报告的记忆障碍与词汇回忆能力下降之间的关联在每周或更频繁的告密者接触时显著更强 (p < 0.0001).
结论:
- 记忆和iADL的信息评估表明与前性,客观测量的总体一致性.
- 举报人报告的准确性因与个人接触的频率而显著受到缓解.
- 了解告密者特征,特别是接触频率,对于解释认知评估数据至关重要.

01:11Observational Studies
9.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

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...

01:30Cognitive Development During Adulthood
296
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

01:29Nursing Assessment
8.1K
The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments...

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

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...
