Published on Revised on 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. You are conducting a study in a new context, location and/or culture, where well-established measurement procedures no longer reflect the new context, location, and/or culture. convergent validity. 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. The criterion and the new measurement procedure must be theoretically related. 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. multitrait-multimethod matrix. The other types of validity described below can all be considered as forms of evidence for construct validity. A construct refers to a concept or characteristic that can’t be directly observed, but can be measured by observing other indicators that are associated with it. A good experiment turns the theory (constructs) into actual things you can measure. All of the other terms address this general issue in different ways. Like other forms of validity, criterion validity is not something that your measurement procedure has (or doesn't have). Criterion validity refers to the ability of the test to predict some criterion behavior external to the test itself. • 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 Criterion validity is the degree to which test scores correlate with, predict, orinform decisions regarding another measure or outcome. These are two different types of criterion validity, each of which has a specific purpose. You create a survey to measure the regularity of people’s dietary habits. You will have to build a case for the criterion validity of your measurement procedure; ultimately, it is something that will be developed over time as more studies validate your measurement procedure. Construct validity is the approximate truth of the conclusion that your operationalization accurately reflects its construct. Convergent validity states that tests having the same or similar constructs should be highly correlated. A measurement procedure can be too long because it consists of too many measures (e.g., a 100 question survey measuring depression). However, rather than assessing criterion validity, per se, determining criterion validity is a choice between establishing concurrent validity or predictive validity. There are, however, some limitations to criterion -related validity… If some types of algebra are left out, then the results may not be an accurate indication of students’ understanding of the subject. To evaluate criterion validity, you calculate the correlation between the results of your measurement and the results of the criterion measurement. This is an extremely important point. This well-established measurement procedure acts as the criterion against which the criterion validity of the new measurement procedure is assessed. 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). 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. In research, it is common to want to take measurement procedures that have been well-established in one context, location, and/or culture, and apply them to another context, location, and/or culture. the importance of criterion-related validity depends on. It is usually an established or widely-used test that is already considered valid. Convergent and divergent validity. To assess criterion validity in your dissertation, you can choose between establishing the concurrent validity or predictive validity of your measurement procedure. Construct validity means that a test designed to measure a particular construct (i.e. The measurement procedures could include a range of research methods (e.g., surveys, structured observation, or structured interviews, etc. For instance, Item 1 might be the statement “I feel good about myself” rated using a 1-to-5 Likert-type response format. Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to … In the section discussing validity, the manual does not break down the evidence by type of validity. Convergent validity refers to how closely the new scale is related to other variables and other measures of the same construct. Validity tells you how accurately a method measures something. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. C onvergent validity and discriminant validity are commonly regarded as ways to assess the construct validity of a measurement procedure (Campbell & Fiske, 1959). Constructvalidity occurs when the theoretical constructs of cause and effect accurately represent the real-world situations they are intended to model. If some aspects are missing from the measurement (or if irrelevant aspects are included), the validity is threatened. verbal reasoning should be related to other types of reasoning, like visual reasoning. Convergent validity is one of the topics related to construct validity (Gregory, 2007). If you are unsure what construct validity is, we recommend you first read: Construct validity.Convergent validity helps to establish construct validity when you use two different measurement procedures and research … 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). 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. Again, measurement involves assigning scores to individuals so that they represent some characteristic of the individuals. The answer is that they conduct research using the measure to confirm that the scores make sense based on their understanding of th…
