What Role Do Reliability and Validity Play in the Effectiveness of Psychological Tests?

Reliability and validity are really important for making sure psychological tests work well.

Reliability means that a test gives the same results over time. For example, if someone takes the same intelligence test several times and gets similar scores, we can say the test is reliable.
Validity checks if a test measures what it says it measures. For example, a depression test should show signs of depression, not feelings of anxiety.

To sum it up, a test needs to be both reliable and valid so that it can truly help with psychological assessments and treatments.
