Table1_Effect of educational brochure compared with video on disease-related knowledge in patients with juvenile idiopathic arthritis: A randomized controlled trial.pdf

IntroductionPatient education plays an important role in the management of chronic diseases such as juvenile idiopathic arthritis (JIA). This study compared the effectiveness of a brochure and a video regarding JIA-related knowledge immediately after the intervention, and at 4 weeks post-intervention.
MethodsA prospective randomized controlled trial was conducted. Patients with JIA or parents were randomized to receive education from either a brochure (n = 50) or a video (n = 50) at the clinic. Participants answered questionnaires about disease-specific knowledge before the intervention (T0), immediately after the intervention (T1), and at follow-up 4 weeks later (T2). The questionnaire comprised 15 multiple-choice questions. Final scores ranged from 0 to 15, and were scaled from 0% to 100% to calculate the percentage of knowledge scores. Ninety participants completed the questionnaire at T2 (42 in the brochure and 48 in the video group).
ResultsThe mean percentage of knowledge scores at T0 was not significantly different between the brochure group and the video group. At T1, the mean percentage of knowledge scores was significantly higher in the video group compared with the brochure group (86.7 ± 12.9% vs. 76.0 ± 21.4%, p = 0.003). Among parents with an educational level below secondary school, the mean percentage of knowledge scores at T1 was significantly higher in the video group compared with the brochure group (83.5 ± 14.4% vs. 69.1 ± 23.2%, p = 0.006). Participants in both groups had significantly higher mean percentage of knowledge scores at T2 compared with T0 (72.7 ± 20.3% vs. 51.1 ± 24.7%, p < 0.001 in the brochure group and 78.3 ± 15.7% vs. 56.1 ± 21.9%, p < 0.001 in the video group). There was no significant difference in the mean percentage of total score change between T2 and T1 between the brochure and video groups (−4.7 ± 13.3% vs. −8.5 ± 11.0%, p = 0.152).
ConclusionThe video was more effective for improving disease-related knowledge immediately post-intervention, particularly in participants with limited education. Although both educational tools had lasting effects on knowledge, the retention rate declined at 4 weeks after both interventions.

引言
患者教育在青少年特发性关节炎（juvenile idiopathic arthritis, JIA）这类慢性病的管理中发挥着重要作用。本研究对比了手册与视频两种宣教方式针对青少年特发性关节炎相关知识的改善效果，分别在干预即刻及干预后4周进行效果评估。

方法
本研究采用前瞻性随机对照试验设计。招募的青少年特发性关节炎患者或其家属被随机分配至手册组（n=50）或视频组（n=50），在门诊接受对应形式的健康宣教。受试者分别在干预前（T0）、干预即刻（T1）以及4周随访时（T2）填写疾病特异性知识问卷。该问卷包含15道单项选择题，原始得分范围为0至15分，将其换算为0%~100%的百分比形式以计算知识得分率。最终共有90名受试者完成了T2阶段的问卷调研，其中手册组42人，视频组48人。

结果
T0阶段，手册组与视频组的知识得分率均值无显著统计学差异。在T1阶段，视频组的知识得分率均值显著高于手册组（86.7±12.9% vs. 76.0±21.4%，p=0.003）。在教育程度低于中学水平的受试者亚组中，T1阶段视频组的知识得分率均值仍显著高于手册组（83.5±14.4% vs. 69.1±23.2%，p=0.006）。两组受试者在T2阶段的知识得分率均值均显著高于T0阶段（手册组：72.7±20.3% vs. 51.1±24.7%，p<0.001；视频组：78.3±15.7% vs. 56.1±21.9%，p<0.001）。两组在T2与T1阶段的总得分变化率均值无显著统计学差异（-4.7±13.3% vs. -8.5±11.0%，p=0.152）。

结论
视频宣教方式在干预即刻对疾病相关知识的提升效果更优，尤其针对受教育程度有限的受试者。尽管两种宣教工具均能对知识掌握产生持续影响，但在两种干预方式实施后的4周，知识留存率均出现下降。
