Reliability and Validity01:29

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.

Data Collection by Survey01:07

Data Collection by Survey

6.5K
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

345
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 Surveys01:27

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...

Systematic Error: Methodological and Sampling Errors01:15

Systematic Error: Methodological and Sampling Errors

1.5K
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:

  • Public Health
  • Epidemiology
  • Survey Methodology

Background:

  • The Youth Risk Behavior Survey (YRBS) is a critical tool for monitoring health-related behaviors among high school students nationwide.
  • Ensuring the reliability of survey instruments is essential for accurate public health surveillance and program development.

Purpose of the Study:

  • To evaluate the test-retest reliability of the 2021 national Youth Risk Behavior Survey (YRBS) questionnaire.
  • To determine the consistency of responses to YRBS items over a short interval.

Main Methods:

  • A convenience sample of 588 high school students completed the 2021 national YRBS questionnaire twice, approximately two weeks apart.
  • Data were analyzed using McNemar's test and Cohen's kappa coefficients to assess agreement between Time 1 and Time 2 responses.
  • Reliability was examined overall and stratified by sex, grade, and race/ethnicity.

Main Results:

  • The 2021 national YRBS questionnaire demonstrated high test-retest reliability, with 96% of items showing at least moderate reliability.
  • 73% of the 74 analyzed items achieved substantial or almost perfect reliability (Cohen's kappa ≥ 0.60).
  • Significant differences between Time 1 and Time 2 responses were found for only 9 items (12%).

Conclusions:

  • The national YRBS questionnaire is a reliable instrument for assessing adolescent health risk behaviors.
  • Findings support the continued use of self-reported data from the YRBS for national health monitoring.
  • Reliable measures are fundamental for effective youth-focused public health programs and policies.
