Patient-reported experience measures have notable ceiling effects which can hinder efforts to learn and improve. This study tested whether an iterative (Guttman-style) satisfaction questionnaire combined with instructions intended to give people agency to critique us primes responses on an ordinal scale and reduces ceiling effects. Among the 161 subjects randomly assigned to complete an iterative satisfaction questionnaire before or after an ordinal scale, there was no difference in mean satisfaction (no priming). The Guttman scale was more normally distributed and had slightly less ceiling effect when compared to the ordinal scale. Iterative satisfaction scales partially mitigate ceiling effects. The absence of priming suggests that attempts to encourage agency and reflection have limited ability to reduce ceiling effects, and alternative approaches should be tested.
患者报告的体验测量存在显著的天花板效应，这可能会阻碍学习和改进的努力。本研究测试了一种迭代式（古特曼式）满意度问卷与旨在赋予人们批评我们的权力的说明相结合，是否能在有序量表上引导回答并减少天花板效应。在随机分配在有序量表之前或之后完成迭代式满意度问卷的161名受试者中，平均满意度没有差异（无引导）。与有序量表相比，古特曼量表的分布更接近正态分布，天花板效应略小。迭代式满意度量表部分减轻了天花板效应。缺乏引导表明，鼓励自主和反思的尝试在减少天花板效应方面能力有限，应测试其他方法。
