Only 56% of outpatient substance abuse treatment programs in the U.S. provide HIV/AIDS education, likely due to the time required to complete existing educational interventions. This report describes results of a third study in a series to develop a brief educational intervention to increase HIV/AIDS knowledge among cocaine-dependent outpatients.
Participants (N=90) were randomized to experimental or control conditions and completed two HIV/AIDS knowledge pre-tests with response formats modified to "true-false-don't know." Pre-test results were later compared to historical controls that completed pre-tests in their original "true-false" format. Next, participants in the experimental condition completed an HIV/AIDS educational intervention while participants in the control condition completed a sham intervention. Participants in both conditions then completed knowledge tests a second time. Participants in both conditions were subsequently crossed over, and then completed knowledge tests a third time. Post-intervention analyses were conducted using test data from all participants who completed the educational intervention (N=56). A subset of these participants (N=40) completed follow-up tests approximately 9 weeks after completing the educational intervention.
Scores on both pre-tests were lower than those observed in historical controls (p<.001). Scores on knowledge tests increased from baseline after participants completed the educational intervention (p<.001), but not after the sham intervention (p>.05). Scores at follow-up remained higher than baseline scores (p<.001).
Modifying response formats to include a "don't know" option likely increases identification of baseline knowledge deficits. This brief intervention is effective at increasing HIV/AIDS knowledge among cocaine-dependent outpatients.
仅有 56%的美国门诊药物滥用治疗项目提供艾滋病毒/艾滋病教育，这可能是因为完成现有教育干预措施所需的时间。本报告介绍了在一系列研究中的第三项研究结果，旨在开发一种简短的教育干预措施，以提高可卡因依赖门诊患者的艾滋病毒/艾滋病知识。
参与者（N=90）随机分为实验组和对照组，并完成了两次艾滋病毒/艾滋病知识预测试，答题格式修改为“真-假-不知道”。预测试结果后来与以原始“真-假”格式完成预测试的历史对照组进行了比较。接下来，实验组的参与者完成了艾滋病毒/艾滋病教育干预，而对照组的参与者完成了虚假干预。然后，两组参与者都再次进行了知识测试。两组参与者随后进行交叉，然后进行了第三次知识测试。对所有完成教育干预的参与者（N=56）的测试数据进行了干预后分析。这些参与者中的一部分（N=40）在完成教育干预后约 9 周完成了随访测试。
两次预测试的得分均低于历史对照组（p<.001）。参与者完成教育干预后，知识测试的得分从基线增加（p<.001），但完成虚假干预后则没有增加（p>.05）。随访时的得分仍高于基线得分（p<.001）。
通过将答题格式改为包含“不知道”选项，可能会增加对基线知识缺陷的识别。这种简短的干预措施可有效提高可卡因依赖门诊患者的艾滋病毒/艾滋病知识。
