Criterion validity reflects the use of a criterion - a well-established measurement procedure - to create a new measurement procedure to measure the construct you are interested in. multitrait-multimethod matrix. There are many occasions when you might choose to use a well-established measurement procedure (e.g., a 42-item survey on depression) as the basis to create a new measurement procedure (e.g., a 19-item survey on depression) to measure the construct you are interested in (e.g., depression, sleep quality, employee commitment, etc.). The criterion is an external measurement of the same thing. Criterion validity A measurement technique has criterion validity if its results are closely related to those given by ). To assess criterion validity in your dissertation, you can choose between establishing the concurrent validity or predictive validity of your measurement procedure. We also stated that a measurement procedure may be longer than would be preferable, which mirrors that argument above; that is, that it's easier to get respondents to complete a measurement procedure when it's shorter. However, the one difference is that an existing measurement procedure may not be too long (e.g., having only 40 questions in a survey), but would encourage much greater response rates if shorter (e.g., having just 18 questions). The measurement procedures could include a range of research methods (e.g., surveys, structured observation, or structured interviews, etc. Construct validity evaluates whether a measurement tool really represents the thing we are interested in measuring. The answer is that they conduct research using the measure to confirm that the scores make sense based on their understanding of th… Each of these is discussed in turn: To create a shorter version of a well-established measurement procedure. This is related to how well the experiment is operationalized. The new measurement procedure may only need to be modified or it may need to be completely altered. Criterion validity:In this validity, the extent to which the outcome of a specific measure or tool corresponds to the outcomes of other valid measures of the same concept is examined. Convergent Validity – When two similar questions reveal the same result. Nonetheless, the new measurement procedure (i.e., the translated measurement procedure) should have criterion validity; that is, it must reflect the well-established measurement procedure upon which is was based. -> correlation decreases->threat to criterion validity. Criterion validity (concurrent and predictive validity) There are many occasions when you might choose to use a well-established measurement procedure (e.g., a 42-item survey on depression) as the basis to create a new measurement procedure (e.g., a 19-item survey on depression) to measure the construct you are interested in (e.g., depression, sleep quality, employee commitment, etc. verbal reasoning should be related to other types of reasoning, like visual reasoning. If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid. For example, the validity of a cognitive test for job performance is the demonstrated relationship between test scores and supervisor performance ratings. the importance of the decision you are making with them. Randomisation is a powerful tool for increasing internal validity - see confounding. You need to consider the purpose of the study and measurement procedure; that is, whether you are trying (a) to use an existing, well-established measurement procedure in order to create a new measurement procedure (i.e., concurrent validity), or (b) to examine whether a measurement procedure can be used to make predictions (i.e., predictive validity). September 6, 2019 A. Criterion-related validity Predictive validity. Concurrent validity pertains to the extent to which the measurement tool relates to other scales measuring the same construct and that have already been validated (Cronbach & Meehl, 1955). Revised on Second, I make a distinction between two broad types: translation validity and criterion-related validity. It could also be argued that testing for criterion validity is an additional way of testing the construct validity of an existing, well-established measurement procedure. But based on existing psychological research and theory, we can measure depression based on a collection of symptoms and indicators, such as low self-confidence and low energy levels. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. This sometimes encourages researchers to first test for the concurrent validity of a new measurement procedure, before later testing it for predictive validity when more resources and time are available. Reliability contains the concepts of internal consistency and stability and equivalence. For example, a survey is being conducted by a news agency for assessing the political opinion of the voters in a town. Convergent validity is one of the topics related to construct validity (Gregory, 2007). Criterion validity evaluates how closely the results of your test correspond to the … Published on A measurement procedure can be too long because it consists of too many measures (e.g., a 100 question survey measuring depression). It mentions at the beginning before any validity evidence is discussed that "historically, this type of evidence has been referred to as concurrent validity, convergent and discriminant validity, predictive validity, and criterion-related validity." Related terms: Test-Retest Reliability; Factor Analysis; Criterion Validity; Discriminant Validity; Predictive Validity; Rating Scale If you think of contentvalidity as the extent to which a test correlates with (i.e., corresponds to) thecontent domain, criterion validity is similar in that it is the extent to which atest … It is usually an established or widely-used test that is already considered valid. These are two different types of criterion validity, each of which has a specific purpose. discriminant. If the outcomes are very similar, the new test has a high criterion validity. Convergent validity states that tests having the same or similar constructs should be highly correlated. A) convergent validity B) discriminant validity C) criterion validity Apparently, the right answer is A), but I think you could still argue for C) in the following manner: Scores on the final exam is the outcome measure and GPA, amount of time spent studying, and class attendance predict it. In the section discussing validity, the manual does not break down the evidence by type of validity. Convergent validity and divergent validity are ways to assess the construct validity of a measurement procedure (Campbell & Fiske, 1959). Results. include concurrent validity, construct validity, content validity, convergent validity, criterion validity, discriminant validity, divergent validity, face validity, and predictive validity. Convergent Validity. Validity tells you how accurately a method measures something. Convergent validity is a subcategory of construct validity. The validity of a test is constrained by its reliability. If you develop a questionnaire to diagnose depression, you need to know: does the questionnaire really measure the construct of depression? When they do not, this suggests that new measurement procedures need to be created that are more appropriate for the new context, location, and/or culture of interest. If anything is still unclear, or if you didn’t find what you were looking for here, leave a comment and we’ll see if we can help. As a result, there is a need to take a well-established measurement procedure, which acts as your criterion, but you need to create a new measurement procedure that is more appropriate for the new context, location, and/or culture.
