What is the primary purpose of including limitations and confidence intervals in an assessment report?

• A. To document measurement error and uncertainty to guide interpretation.
• B. To inflate the significance of the findings.
• C. To speed up decision making by presenting a single definitive answer.
• D. To replace clinical judgment.

Answer: (A)

In assessment reporting, results aren’t absolute—they come with uncertainty from measurement error, sampling variation, and the instrument’s properties. Including limitations and confidence intervals makes this uncertainty explicit, guiding interpretation rather than treating a single score as a definitive answer. A confidence interval shows a range around the observed score where the true value is likely to lie, given a chosen probability. This helps clinicians judge how precise the measurement is, whether observed differences matter, and how much weight to give conclusions for individuals or groups not fully represented by the sample. Stating limitations highlights factors that could affect results—such as cultural relevance, administration conditions, or the test’s validity in the client’s context. Together, they support transparent, ethically grounded decision making and refrain from inflating findings, rushing decisions with a single definitive number, or replacing clinical judgment.
