Little is known about the effects of videotape-based education on knowledge and anxiety levels among patients with melanoma. We sought to evaluate effects of a professionally produced videotape on the knowledge and distress levels among patients with newly diagnosed melanoma. Secondarily, we sought to compare these effects with those of a traditional clinic visit.
We conducted a randomized controlled trial involving 217 patients. An intervention group underwent questionnaire-based testing of melanoma knowledge and anxiety/distress levels before and after viewing an educational videotape. A control group underwent similar testing before and after a clinic visit.
The videotape and clinical encounter significantly increased knowledge and decreased anxiety. Improvement in knowledge levels was significantly greater after viewing the videotape compared with the clinic visit, whereas anxiety levels decreased to a greater degree after the clinical encounter. Whether or not a synergistic relationship may exist between exposure to an educational videotape and a physician visit was not specifically evaluated in this study.
Videotape-based education may be more effective than that provided by a clinic visit, whereas the clinical encounter appears to be more effective in alleviating patient anxiety/distress.
关于基于录像带的教育对黑色素瘤患者知识水平和焦虑程度的影响，目前所知甚少。我们试图评估专业制作的录像带对新诊断黑色素瘤患者知识水平和痛苦程度的影响。其次，我们试图将这些影响与传统门诊就诊的影响进行比较。
我们进行了一项涉及217名患者的随机对照试验。干预组在观看教育录像带前后接受基于问卷的黑色素瘤知识及焦虑/痛苦程度测试。对照组在门诊就诊前后接受类似测试。
录像带和临床问诊均显著增加了知识并降低了焦虑。与门诊就诊相比，观看录像带后知识水平的提高更为显著，而临床问诊后焦虑程度的降低更为明显。本研究未专门评估观看教育录像带与医生问诊之间是否可能存在协同关系。
基于录像带的教育可能比门诊就诊更有效，而临床问诊在减轻患者焦虑/痛苦方面似乎更有效。
