The goal of this study was to compare prose and pictorial-based information pamphlets about the medication methotrexate in the domains of free recall, cued recall, comprehension and utility.
A single blind, randomized trial of picture versus prose-based information pamphlets including 100 participants aged 18-65 years of age, who had not completed high school, could read English, and had no prior knowledge about methotrexate. Superiority of pamphlet type was assessed using immediate free recall, cued recall and comprehension.
There were no differences between picture and prose pamphlets in free recall, cued recall, and comprehension either immediately or after a 1-week interval. Immediate free recall of important information was 17-26%; free recall fell even lower to 7-16% after 1 week. The pictorial pamphlet was preferred over the prose-based pamphlet.
This study found no benefit in free recall, cued recall, or comprehension through the addition of pictograms to a simple prose-based medication pamphlet.
In order for them to be effective in clinical practice, even simple medication information pamphlets that have been assessed for patients' ability to comprehend them cannot be used as the sole means for conveying important medication-related information to patients.
本研究旨在比较关于药物甲氨蝶呤的基于散文和基于图片的信息小册子在自由回忆、提示回忆、理解和实用性等方面的差异。
采用单盲、随机试验，比较 100 名年龄在 18-65 岁、未完成高中学业、能阅读英语且对甲氨蝶呤一无所知的参与者阅读基于图片和基于散文的信息小册子。使用即时自由回忆、提示回忆和理解来评估小册子类型的优越性。
无论是即时还是 1 周后，图片小册子和散文小册子在自由回忆、提示回忆和理解方面均无差异。即时重要信息的自由回忆率为 17-26%；1 周后，自由回忆率甚至降至 7-16%。图片小册子比基于散文的小册子更受欢迎。
本研究发现，在简单的基于散文的药物小册子中添加象形图并没有提高自由回忆、提示回忆或理解能力。
为了在临床实践中有效，即使已经评估了患者理解能力的简单药物信息小册子也不能作为向患者传达重要药物相关信息的唯一手段。
