When people talk about psychological tests, they often ask whether the test is valid or not. What exactly does this mean? Validity is a measure of how well a test measures what it claims to measure.
Psychological testing is the administration of psychological tests. Scores are thought to reflect individual or group differences in the construct the test purports to measure.
Personality assessment , the measurement of personal characteristics. Assessment is an end result of gathering information intended to advance psychological theory and research and to increase the probability that wise decisions will be made in applied settings e. The approach taken by the specialist in personality assessment is based on the assumption that much of the observable variability in behaviour from one person to another results from differences in the extent to which individuals possess particular underlying personal characteristics traits. The assessment specialist seeks to define these traits, to measure them objectively, and to relate them to socially significant aspects of behaviour. A distinctive feature of the scientific approach to personality measurement is the effort, wherever possible, to describe human characteristics in quantitative terms. How much of a trait manifests itself in an individual? How many traits are present?
In this chapter, I present two broad topics: psychological measurement, or the process of assigning numbers to observations to quantify important characteristics of individuals, and the use of testing and assessment within counseling psychology. The first half of the chapter describes principles of measurement, including methods of scale and test development and evaluating the psychometric characteristics of tests reliability and validity. The second half focuses on the use of testing and assessment, including models of assessment within counseling psychology, various types of commonly used assessment tools, computer-assisted and Internet-based assessment, gender and diversity issues, considerations in the selection and use of assessment in counseling, and professional and ethical issues. Keywords: assessment , testing , validity , reliability , individual differences. The psychological test was the invention that revolutionized psychological science, comparable in its impact to the telescope in physics and the microscope in biology. It opened up a new world for psychology to explore.
Validity is the extent to which a concept , conclusion or measurement is well-founded and likely corresponds accurately to the real world. The validity of a measurement tool for example, a test in education is the degree to which the tool measures what it claims to measure. In psychometrics , validity has a particular application known as test validity : "the degree to which evidence and theory support the interpretations of test scores" "as entailed by proposed uses of tests". It is generally accepted that the concept of scientific validity addresses the nature of reality in terms of statistical measures and as such is an epistemological and philosophical issue as well as a question of measurement. The use of the term in logic is narrower, relating to the relationship between the premises and conclusion of an argument.
By Dr. Saul McLeod , published The term reliability in psychological research refers to the consistency of a research study or measuring test. For example, if a person weighs themselves during the course of a day they would expect to see a similar reading. Scales which measured weight differently each time would be of little use.
