The fifth process (outcome assessment) uses what during outcome assessment?

• A. Tests and measures (reliable, valid, sensitive, and specific)
• B. Imaging studies only
• C. Patient preference surveys only
• D. Administrative data

Answer: (A)

During outcome assessment, use tests and measures that are reliable, valid, and sensitive (with good specificity when relevant) because they provide trustworthy evidence of a patient’s status and progress. Reliability means the results are consistent across repeated tests or different raters, so you can trust changes aren’t just random variation. Validity ensures the tool actually measures what you intend to measure—for example, a balance test should reflect balance, not just general fitness. Sensitivity (responsiveness) means the measure can detect meaningful change over time, so you can tell if the patient is improving, staying the same, or worsening. These properties together give you credible data to guide treatment decisions, track outcomes, and communicate progress. Imaging studies alone aren’t sufficient for outcome assessment because they show anatomy or structure, not necessarily function or patient-perceived improvement. Patient preference surveys are valuable but don’t capture objective changes in function. Administrative data can indicate utilization or billing patterns but not the actual clinical outcomes. So, the most robust option is using tests and measures with strong psychometric properties to accurately assess outcomes.
