What is the difference between a psychological concept and a psychological construct?

A psychological concept is an abstraction formed by generalization from particulars. A psychological construct is a concept with scientific purpose that is operationalized and can be measured and studied.

Why do we use psychological testing?

Psychological testing is used because many psychological traits are not directly observable or self-reportable, thus requiring indirect methods for assessment.

What is the primary objective of psychological testing?

The primary objective is to obtain a numerical gauge regarding an ability or attribute.

What differentiates psychological assessment from psychological testing?

Psychological testing measures psychology-related variables using devices or procedures, while psychological assessment involves gathering and integrating data for psychological evaluation.

Where can you find information about how a particular test was developed?

Information can be found in test manuals, catalogs, professional books, reference volumes, journal articles, and online databases.

What does psychometric soundness refer to?

Psychometric soundness refers to the technical quality of a test or assessment tool.

What is the Mental Measurements Yearbook?

A catalog of tests that updates every three years, providing detailed information about each test, including the publisher and intended population.

What are the tools of psychological assessment?

Tools of psychological assessment include tests, interviews, portfolios, observations, and computer-assisted assessments.

What is the main goal of therapeutic psychological assessment?

It allowed opposing expert testimony to be admissible even if it had not won general acceptance in the scientific community.

What is the significance of informed consent in psychological testing?

Informed consent involves obtaining permission to proceed with services based on understanding the risks and benefits.

What is differential weighting in the context of discriminatory testing?

Differential weighting refers to the varying importance placed on different items or procedures in a test, which can affect outcomes.

What is the purpose of item discrimination index?

The item discrimination index indicates how well a test item can differentiate between high and low scorers.

What constitutes a good psychological test?

A good psychological test is clear, efficient, accurate, psychometrically sound, and fits its intended purpose.

How does culture influence test-taker characteristics?

Culture affects verbal communication, nonverbal communication, behavior, and standards of evaluation.

What is the difference between random sampling and stratified sampling?

Random sampling gives each individual an equal chance of selection, while stratified sampling divides the population into subgroups and randomly selects from each stratum.

What is reliability in the context of psychological measurements?

Reliability refers to the consistency of scores in measurement, indicating that observed scores reflect true scores.

What are the main types of validity?

Content validity, construct validity, criterion-related validity, and face validity.

What is the process of validation?

The process of gathering and evaluating evidence regarding how well a test measures what it purports to measure.

What are the steps in the test development process?

Test conceptualization, test construction, test tryout, analysis, and revision.

What does CAT (computer adaptive measurement) do?

CAT is interactive computer-administered testing that adjusts difficulty based on the responses of test-takers.
