Communication of treatment information is critical in orthodontics. The challenge lies in doing so effectively such that patients will understand and remember, which is the definition of true informed consent. Previous studies have established that information is more readily remembered when presented using multimedia presentations. Likewise, humor has been shown to increase information retention.
Two videos, 1 humorous (H) and 1 unhumorous (U), were produced with identical information about orthodontic treatment consent. Thirty-eight new orthodontic patients were randomly selected and divided into H (n = 20) and U (n = 18) video groups. Identical questionnaires with multiple-choice responses to judge memory of the content were completed by both groups immediately after watching the video (T1) and 6 weeks later (T2). A one-tailed Welch's t test was used to analyze the scores.
At T1, there was no significant difference in the scores of the questionnaire between H and U groups, whereas at T2, there was a significant difference between groups. The intragroup score difference was also analyzed, with a significant decrease from T1 to T2 in the U, but not H, group. Subjective questions were also asked regarding content. No significant differences were found between the groups regarding the informativeness of each video; however, willingness to watch again and memorability of the content were significantly higher in the H group.
Patients who received orthodontic treatment information presented with humor retained significantly more of that information after 6 weeks compared with patients who received the same information without humor. Patients who received the humorous content subjectively stated they were more likely to rewatch the video and also found the information presented in this manner to be more memorable.
在正畸学中，治疗信息的交流至关重要。挑战在于要做到有效传达，使患者能够理解并记住，这才是真正知情同意的定义。先前的研究已经证实，使用多媒体演示呈现信息时，患者更容易记住。同样，幽默也被证明可以提高信息的保留率。
制作了两个视频，1 个幽默（H），1 个不幽默（U），内容均为正畸治疗同意书的相关信息。随机挑选了 38 名新的正畸患者，分为 H（n=20）和 U（n=18）视频组。两组患者在观看视频后立即（T1）和 6 周后（T2）填写了相同的多项选择题问卷，以判断对内容的记忆。采用单侧 Welch 检验分析得分。
T1 时，H 组和 U 组的问卷得分没有显著差异，而 T2 时，两组之间有显著差异。还分析了组内评分差异，U 组的评分从 T1 到 T2 显著下降，但 H 组没有。还询问了有关内容的主观问题。两组对每个视频的信息丰富度没有显著差异；然而，H 组再次观看视频的意愿和内容的可记性明显更高。
与接受无幽默内容的患者相比，接受幽默正畸治疗信息的患者在 6 周后保留了更多的信息。接受幽默内容的患者主观表示他们更有可能再次观看视频，并且他们认为以这种方式呈现的信息更具记忆性。
