When considering a special test for orthopedic assessment of a client, the validity of the test is important because the:

• A. results of the test can be standardized
• B. test measures what it is supposed to measure
• C. results of the test are reproducible
• D. test can be accurately performed by someone else

Answer: (B)

Validity is about whether a test actually measures the specific function or impairment it's intended to assess. In orthopedic assessment, you want the test result to reflect the true condition or limitation you’re trying to identify, not something else like general pain or fear of movement. When a test has good validity, a positive result truly indicates the intended impairment and a negative result suggests its absence. If validity is lacking, you might misinterpret the situation, leading to inappropriate treatment decisions. Standardization helps ensure the procedure is performed the same way every time, reliability (whether results are consistent across trials or testers) ensures repeatable outcomes, and having someone else able to perform the test accurately speaks to feasibility and general use. These qualities are important, but they don’t address whether the test measures the exact construct you need. The key point is that validity confirms the test measures what it’s supposed to measure.
