Validity Assessment

Validity assessment refers to evaluating how well a test, measurement, or tool accurately measures what it is intended to measure. It ensures that the results are meaningful and trustworthy. For example, if a mood questionnaire is designed to assess depression, validity assessment determines whether the questionnaire actually captures depression symptoms and not unrelated factors. This process involves various methods, like comparing it to other established tools or examining if it correlates with real-world outcomes. Overall, validity assessment helps confirm that the conclusions drawn from the data are accurate and relevant.
