Preparation and planning ahead are all-important in carrying out an evaluative study. Systematic evaluation provides evidence for the justification of a given treatment or intervention. In this third article looking at clinical evaluation, the process of posing a question which lends itself to study is examined. Questioning, it is argued here, can be seen as having three progressively complex levels. These can uncover: first, whether an effect has taken place; second, what may have caused the effect; and third, how the effect might be improved. Previous articles in this series appeared in the March 13 and April 10 issues of Nursing Times.
在开展一项评估性研究时，提前做好准备和规划至关重要。系统评估为某种特定治疗或干预措施的合理性提供依据。在这篇探讨临床评估的第三篇文章中，我们将审视提出一个适合研究的问题的过程。本文认为，提问可分为三个逐渐复杂的层次。这些层次能够揭示：其一，是否产生了某种效果；其二，可能导致该效果的原因是什么；其三，如何改善这一效果。本系列的前几篇文章发表在《护理时报》3月13日和4月10日的期刊上。
