For example, a survey is being conducted by a news agency for assessing the political opinion of the voters in a town. Concurrent validity refers to whether a test’s scores actually evaluate the test’s questions. Criterion validity refers to the ability of the test to predict some criterion behavior external to the test itself. include concurrent validity, construct validity, content validity, convergent validity, criterion validity, discriminant validity, divergent validity, face validity, and predictive validity. 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. On the bottom part of the figure (Observation) w… If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid. There are two things to think about when choosing between concurrent and predictive validity: The purpose of the study and measurement procedure. discriminant. If it doesn’t show any signs of this validity, it may be measuring something else. 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. It’s central to establishing the overall validity of a method. Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to … Convergent Validity. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. External validity is about generalization: To what extent can an effect in research, be generalized to populations, settings, treatment variables, and measurement variables?External validity is usually split into two distinct types, population validity and ecological validity and they are both essential elements in judging the strength of an experimental design. The new measurement procedure may only need to be modified or it may need to be completely altered. Convergent and divergent validity. 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. Hope you found this article helpful. For example, participants that score high on the new measurement procedure would also score high on the well-established test; and the same would be said for medium and low scores. A mathematics teacher develops an end-of-semester algebra test for her class. 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 criterion and the new measurement procedure must be theoretically related. It says 'Does it measure the cons… Each of these is discussed in turn: To create a shorter version of a well-established measurement procedure. Thanks for reading! To establish convergent validity, you need to show that measures that should be related are in reality related. • Content Validity -- inspection of items for “proper domain” • Construct Validity -- correlation and factor analyses to check on discriminant validity of the measure • Criterion-related Validity -- predictive, concurrent and/or postdictive Two methods are often applied to test convergent validity. Construct validity means that a test designed to measure a particular construct (i.e. Whilst the measurement procedure may be content valid (i.e., consist of measures that are appropriate/relevant and representative of the construct being measured), it is of limited practical use if response rates are particularly low because participants are simply unwilling to take the time to complete such a long measurement procedure. To help test the theoretical relatedness and construct validity of a well-established measurement procedure. Convergent Validity – When two similar questions reveal the same result. Construct validity is the approximate truth of the conclusion that your operationalization accurately reflects its construct. Also called concrete validity, criterion validity refers to a test’s correlation with a concrete outcome. There are four main types of validity: Note that this article deals with types of test validity, which determine the accuracy of the actual components of a measure. Convergent validity and divergent validity are ways to assess the construct validity of a measurement procedure (Campbell & Fiske, 1959). In this article, we first explain what criterion validity is and when it should be used, before discussing concurrent validity and predictive validity, providing examples of both. After all, if the new measurement procedure, which uses different measures (i.e., has different content), but measures the same construct, is strongly related to the well-established measurement procedure, this gives us more confidence in the construct validity of the existing measurement procedure. From: The Measurement of Health and Health Status, 2017. Validity contains the concepts of content, face, criterion, concurrent, predictive, construct, convergent (and divergent), factorial and discriminant.
