Understanding the results of psychological tests is really important. Two key ideas we need to know about are validity and reliability.
Validity is all about how well a test measures what it says it measures.
For example, if a test is made to see if someone has depression, it should focus on symptoms of depression, not symptoms of anxiety.
Now, let’s talk about reliability. This means that the test results should be the same if the test is taken again under similar conditions.
For instance, if someone takes the same IQ test two times, their scores should be quite similar and not change a lot.
When we use a tool to measure how well therapy is working, it needs both high validity and high reliability.
If a test has good validity but low reliability, it can be hard for doctors to trust the results.
So, having both high validity and high reliability helps make the results clearer and leads to better choices in planning treatment.
