How should you interpret a low score on a reliability subscale?

• A. It may indicate careless responding or misinterpretation; review items for clarity or retake if allowed.
• B. It is a universal indicator of the test's validity.
• C. It means the test should always be retaken.
• D. It confirms the person has high integrity.

Answer: (A)

A low score on a reliability subscale signals inconsistency in responses across items that are designed to measure the same construct. It often points to issues with how the respondent engaged with the items rather than something about the construct itself. The most helpful interpretation is that there may be careless responding, misinterpretation, or unclear wording in the items. In practice, you’d review the items for clarity, look for ambiguous or double-barreled statements, check for mis-keyed items, and consider whether a retake is allowed. If a retake is possible, it can help determine whether the low reliability was a one-time problem or tied to item design.

This interpretation fits because reliability is about internal consistency, not about the test’s overall validity or a person’s character. A low reliability score does not universally indicate validity problems, nor does it confirm integrity or mandate a retake in every case.
