Surveys

17.1K
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.

Types of Surveys

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...

Data Collection by Survey

9.1K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

890
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.

Study Designs in Epidemiology

1.1K
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Systematic Error: Methodological and Sampling Errors

11.1K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Area of Science:

  • Health Sciences
  • Psychometrics
  • Clinical Measurement

Background:

  • Numerous instruments exist to assess oral health-related quality of life (OHRQoL).
  • Challenges arise from varying methodological validation and conceptual differences, hindering instrument selection and comparison.
  • Clinicians and researchers need reliable tools to choose questionnaires reflecting individual meaningfulness.

Purpose of the Study:

  • To highlight the importance of using appropriate checklists for selecting methodologically sound health measurement instruments.
  • To introduce the COSMIN checklist as a tool for evidence-based instrument selection.
  • To advocate for the broader adoption of the COSMIN checklist to enhance OHRQoL research.

Main Methods:

  • Discussion of the COSMIN checklist's development and structure.
  • Explanation of the checklist's evaluation criteria for methodological quality.
  • Outline of the four-step process involved in using the COSMIN checklist.

Main Results:

  • The COSMIN checklist provides a standardized framework for assessing the quality of health measurement instrument studies.
  • It includes criteria for methodological rigor, Item Response Theory application, and results generalization.
  • Expertise in psychometrics or clinimetrics is beneficial for comprehensive checklist application.

Conclusions:

  • The COSMIN checklist is essential for standardizing cross-cultural adaptations and enabling comparisons in measurement studies.
  • It serves as a valuable tool for students, editors, and reviewers in evaluating measurement properties.
  • Popularizing the COSMIN checklist will improve the selection and evaluation of health measurement instruments, advancing OHRQoL research.
