Question

Quizplus · Accepted Answer

Test-retest reliability assumes that the underlying characteristic being measured remains stable between test administrations. However, health status can genuinely change over time due to treatment, disease progression, or natural recovery. Therefore, variations observed in repeated health status measurements may reflect actual changes in the person's health rather than inconsistencies in the measurement tool itself.
