本研究的目的是评估简短的团体干预、积极选择干预（PCI）和标准干预（SI）的有效性，以增加安全套的使用和使用安全套的意愿，并改变安全套使用的态度和信念。研究设计为随机对照试验。参与者是347名患有艾滋病毒感染的异性恋非洲裔美国人快克可卡因使用者。在摄入时以及摄入后3个月和9个月收集数据。收集行为和社会认知数据。虽然这两个简短的干预取得了积极的成果，干预组之间的结果有显着差异。PCI组在3个月时的平均性伴侣数量显著较低。被分配到PCI报告与付费伴侣发生性行为的比例显著下降，而向其伴侣披露其血清状态的比例增加。SI组在这些指标上无显著差异。发现避孕套使用指标、避孕套使用态度和自我效能信念存在显着的时间效应。两组的这些指标从摄入到一个月都显著增加。一个显著的时间-组效应被发现，PCI组的情境自我效能感显著增加，而SI组没有。结果还显示了显著的时间效应。平均安全套使用率、使用安全套意愿、态度、安全套使用自我效能信念在3个月和9个月之间差异有统计学意义。然而，没有明确的变化模式。研究结果表明，旨在减少艾滋病毒的简短的群体干预措施可以帮助异性恋吸毒者感染艾滋病毒，增加安全套的使用和使用安全套的意图，并改变安全套使用的态度和信念。一个显着的时间组的影响，观察只有情景自我效能，表明有限的额外的PCI干预的效果。鉴于两组之间类似的积极发现，需要更多的研究来确定简短干预的哪些组成部分会改变动机和风险行为。
The purpose of this study was to assess the efficacy of brief group interventions, the positive choices intervention (PCI) and a standard intervention (SI), to increase condom use and intention to use condoms and to change condom use attitudes and beliefs. The design of the study was a randomized comparative trial. Participants were 347 heterosexual African American crack cocaine users living with HIV infection. Data were collected at intake and at three and nine months after intake. Behavioral and sociocognitive data were collected. Although both brief interventions achieved positive results, there were significant differences in outcomes between the interventions groups. The mean number of sex partners was significantly lower in the PCI group at three months. The proportion of those assigned to the PCI reporting sex with a paid partner significantly decreased, while the proportion disclosing their serostatus to their partners increased. There were no significant differences on these measures in the SI group. Significant time effects were found on measures of condom use, condom use attitudes, and self-efficacy beliefs. These measures significantly increased from intake to one month for both groups. One significant time-by-group effect was found. The measure of situational self-efficacy significantly increased in the PCI group, but not the SI group. Results also showed significant time-by-time effects. Mean condom use, intention to use condoms, attitudes, and condom use self-efficacy beliefs showed significant difference between three and nine months. However, there was no clear pattern of change. Findings suggest that brief group interventions designed to reduce HIV can help heterosexual drug users living with HIV infection increase condom use and intention to use condoms and change condom use attitudes and beliefs. A significant time-by-group effect was observed only for situational self-efficacy, suggesting limited additional efficacy of the PCI intervention. Given similar positive findings between groups, more research is needed to determine which components of brief interventions produce changes in motivations and risk behaviors.
