This HIV/STI risk reduction clinical trial implemented in short-term alcohol detoxification employed a randomized block design to evaluate three intervention conditions for feasibility, safety, and potential for changing sexual risk attitudes, motivations, and behavior: (a) nonintervention control (standard HIV information dissemination), (b) brief motivational intervention (BMI) for resolution of ambivalence and sex risk reduction planning, and (c) BMI with biological feedback based on testing for sexually transmitted infections (STIs). Findings revealed that BMI can be feasibly implemented during detoxification treatment with individuals with significant substance impairment. BMI, whether coupled with biological feedback or not, enhanced motivation for increasing behaviors that protect from STI. Sexual risk behavior did not change in any of the groups to a statistically significant degree; however, additional analyses suggest negative biological feedback may have resulted in slightly increased level of sexual activity, undoing behavioral effects of increased motivation for sexual risk reduction, perhaps by distorting participants' perception of risk.
这项在短期酒精解毒治疗中开展的降低艾滋病毒/性传播感染风险的临床试验采用随机区组设计,以评估三种干预条件在可行性、安全性以及改变性风险态度、动机和行为方面的潜力:(a) 无干预对照(标准艾滋病毒信息传播),(b) 用于解决矛盾心理和降低性风险规划的简短动机干预(BMI),以及 (c) 基于性传播感染(STIs)检测的带有生物反馈的BMI。研究结果显示,BMI对于有严重物质损害的个体而言,在解毒治疗期间可以切实可行地实施。BMI无论是否与生物反馈相结合,都增强了增加预防性传播感染行为的动机。在任何一组中,性风险行为都没有在统计学上发生显著变化;然而,进一步分析表明,负面生物反馈可能导致性活动水平略有上升,抵消了降低性风险动机增加所带来的行为效果,这可能是由于扭曲了参与者对风险的认知。
