We evaluate the impact of a videotape specially produced to supplement written information about preventive HIV vaccine trials. One hundred eighty-six injection drug users were randomly assigned to an education session in which either: (a) a pamphlet was reviewed before a brief discussion period or (b) the videotape was watched prior to reviewing the pamphlet and participating in the discussion. The relationship among retention of information, trust in government, and willingness to participate in a vaccine trial was tested before the presentation of information, immediately after, and 1 month later. Results indicate that both methods produced significant increases in knowledge immediately after information presentation, but only the video-supplemented group retained the information 1 month later. Subjects receiving the video supplement also showed a significant increase in trust at the first posttest period, but this increase was not maintained 1 month later. Regardless of group assignment or evaluation point, willingness to participate was not associated with knowledge but was associated with trust in government.
我们评估了一盘专门制作的录像带对补充有关预防性艾滋病毒疫苗试验书面信息的影响。186名注射吸毒者被随机分配到一个教育环节，在该环节中，他们要么：(a) 在简短讨论期之前阅读一份宣传册，要么：(b) 在阅读宣传册并参与讨论之前观看录像带。在信息展示之前、之后立即以及1个月后，测试了信息留存、对政府的信任以及参与疫苗试验的意愿之间的关系。结果表明，两种方法在信息展示后立即都显著提高了知识水平，但只有视频补充组在1个月后仍保留了这些信息。接受视频补充的受试者在第一次测试后阶段对政府的信任也显著增加，但这种增加在1个月后没有持续。无论分组情况或评估时间点如何，参与意愿与知识无关，而是与对政府的信任有关。
