Quizplus · Accepted Answer

Andrea needs a scale with good reliability, meaning it consistently produces the same results over time. This is important for measuring the effectiveness of the drug over the course of multiple weeks. Option A, standardization, refers to consistent administration of the scale to different participants and is less relevant in this scenario. Option B, predictive validity, refers to the ability of the scale to predict future outcomes and is not as important as consistency over time. Option D, content validity, refers to the extent to which the scale measures the construct it is intended to measure, and while important, is not mentioned as a priority in this scenario.
