Item Discrimination & Selection Research Paper

¶ … discrimination, assessment and some of the related consequences. The first question asks what the general definition of item discrimination is. The second question asks how topic of item discrimination can be assessed. The problem then asks what the consequences for item selection when the criteria are total test scores as opposed to external scores. While there are going to be some consistencies and patterns and while this will even exist with external scores, one should be very careful to analyze items correctly and in the proper context. Questions Answered

McGrory et al. notes that performance on psychometric tests is key to diagnosis and the monitoring of dementia treatment, among other psychological treatments and assessments. Results are often assessed based on the total score. However, there is often additional information in individual items of tests which vary based on several values. These values are known as difficulty and discrimination. Item difficulty refers to the overall ability level at which the probability of responding correction is about fifty percent. Item discrimination is an index of how well an item can be differentiated between patients of varying levels of things like severity. Using external scores as a guidepost can be problematic based on the differing of questions that are used, the severity of the patients involved, the item discrimination levels in both surveys and so forth. McGrory et al. goes on to note...

In the McGrory study, the overall systematic review was aimed to identify all published literature which had applied the prior-mentioned IRT to instruments assessing global cognitive function in people with dementia (McGrory et al., 2014; McElhiney, Kang, Starkey & Ragan, 2014).
Conclusion

Per the above, item discrimination and item selection are items that could and should be assessed when it comes to any questions that are related to assessing cognitive function and performance. This can be true in mentally healthy patients and students but it can also stretch across all other forms and realms of cognitive psychology. It should be noted that mixing and matching questions and results can be problematic because there are going to be differences and thus the "apples to apples" comparison yardstick will not be there. There can and might be situations where two tests can be compared side by side in terms of the questions and their results. However, this will be rare because the tests will tend to be different, the pool of test-takers will tend to be different and so forth. Making conclusions based on unlike tests or pools of test-takers is less than wise because the conclusions garnered will probably be incorrect or at least unprovable.
