This article describes process data from a randomized controlled trial among 781 adults recruited in the emergency department who reported recent drug use and were randomized to: intervener-delivered brief intervention (IBI) assisted by computer, computerized BI (CBI), or enhanced usual care (EUC). Analyses examined differences between baseline and post-intervention on psychological constructs theoretically related to changes in drug use and HIV risk: importance, readiness, intention, help-seeking, and confidence. Compared to EUC, participants receiving the IBI significantly increased in confidence and intentions; CBI patients increased importance, readiness, confidence, and help-seeking. Both groups increased relative to the EUC in likelihood of condom use with regular partners. Examining BI components suggested that benefits of change and tools for change were associated with changes in psychological constructs. Delivering BIs targeting drug use and HIV risk using computers appears promising for implementation in healthcare settings. This trial is ongoing and future work will report behavioral outcomes.
本文描述了一项在急诊科招募的 781 名近期有药物使用史的成年人中进行的随机对照试验的过程数据，这些成年人被随机分配到以下三组：干预者提供的计算机辅助简短干预（IBI）、计算机化 BI（CBI）或增强的常规护理（EUC）。分析比较了干预前后与药物使用和 HIV 风险变化相关的心理结构的差异：重要性、准备程度、意图、寻求帮助和信心。与 EUC 相比，接受 IBI 的参与者在信心和意图方面显著增加；CBI 患者在重要性、准备程度、信心和寻求帮助方面有所增加。与 EUC 相比，两组人在与固定伴侣发生性行为时使用安全套的可能性都有所增加。对 BI 成分的检查表明，改变的好处和改变的工具与心理结构的变化有关。使用计算机提供针对药物使用和 HIV 风险的 BI 似乎有望在医疗保健环境中实施。该试验正在进行中，未来的工作将报告行为结果。
