概括
与面对面的方法相比,用于复合时间权衡 (cTTO) 的网络调查是不可靠的. 离散选择实验 (DCE) 调查显示出良好的可靠性,但需要考虑DCE中的定位效应.
科学领域:
- 卫生经济学 卫生经济学
- 心理测量 心理测量 心理测量
- 调查方法 调查方法
背景情况:
- 基于偏好的措施对于健康经济学评估至关重要.
- 传统的估值调查使用面对面或网络面板方法.
- 目前正在研究用于估值任务的不同调查模式的可靠性.
研究的目的:
- 为了比较面对面与基于网络的调查对健康状况评估的可靠性.
- 评估三个不同的估值任务:复合时间权衡 (cTTO),离散选择实验 (DCE) 和持久的DCE.
- 评估调查模式对基于偏好的措施的一致性的影响.
主要方法:
- 一个日本普通人口样本 (N=1000) 被招募用于面对面和网络调查.
- 参与者被分配到具有持续时间任务的cTTO,DCE或DCE (N=334个小组).
- 使用测试复试分析评估可靠性,计算协议百分比和类内相关系数 (ICCs).
主要成果:
- 综合时间权衡 (cTTO) 评分显示了面对面和网络调查之间的系统差异,一致性很差 (ICC=0.37面对面,ICC=0.59网络).
- 离散选择实验 (DCE) 和持续时间的DCE在两个调查模式中都表现出良好的可靠性 (超过70%的一致性).
- DCE的可靠性受到健康状况卡在调查波之间的相同位置的影响.
结论:
- 由于可靠性问题,不建议基于网络的cTTO调查作为面对面调查的替代品.
- 离散选择实验 (DCE) 调查在不同模式中提供可靠的健康状况评估.
- 在DCE调查中对健康状况的定位影响需要仔细考虑,以确保准确和一致的结果.

Reliability and Validity
12.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Surveys
14.8K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Self-Report Tests of Personality
353
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Types of Surveys
46
Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Response Surface Methodology
133
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Measures of Central Tendency
16.0K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...
