The Boston Diagnostic Aphasia Examination, or BDAE-2, is a well-known tool used to diagnose speech disorders. In Serbia, it has been in use for a while, but there is a lack of information on how well it works for Serbian speakers. A recent study set out to change that. Researchers wanted to see if the BDAE-2 is reliable and valid for Serbian-speaking individuals with aphasia. Aphasia is a condition that affects a person's ability to speak, understand, read, or write. It usually happens after a stroke.

The study involved 119 people with aphasia caused by a stroke and 51 people without any neurological issues. All participants were given a Serbian version of the BDAE-2. The results were quite positive. The Serbian version of the BDAE-2 showed strong internal consistency. This means that the different parts of the test are measuring the same thing. It also showed high inter-rater reliability. This means that different people giving the test would get similar results. The test also showed satisfactory construct validity. This means that the test measures what it is supposed to measure. Furthermore, the test was able to tell the difference between people with aphasia and those without it. This is known as discriminative capacity.

Some parts of the test were particularly good at telling the difference between different types of aphasia and how severe the aphasia was. The study also found that things like gender, education, and age can affect how well someone does on certain parts of the test. This is important to keep in mind when using the test. In the end, the study found that the BDAE-2 is a reliable tool for diagnosing aphasia in Serbian speakers. It has good psychometric properties, which means it is a good test. However, it is important to remember that no test is perfect. There are always things that can affect the results. For example, the test might not work as well for people with certain types of aphasia. It is also important to remember that the test is just one tool among many. It should be used along with other tools and information to make a diagnosis.
