Audio computer-assisted self-interviewing (A-CASI) is now widely used to gather information from many types of research participants, including injection drug users (IDUs). The purpose of this study was to describe how HIV-positive IDUs participating in an intervention trial viewed A-CASI and to identify the characteristics of participants who held unfavorable attitudes toward A-CASI. Using a sample of participants who completed 12-month assessments (n=821), we found that most (>80%) of the sample held favorable or neutral attitudes toward A-CASI. Approximately 18% said that they would prefer an interview with a person to a computer, 12% said that they did not understand the questions they heard on the computer, and 14% said that the computer made it hard to be open and honest about risk behavior. Multivariate analyses found that participants who were more socially marginalized (with unstable housing and lower sense of empowerment) and had greater physical limitations and lower CD4 cell counts were consistently more likely to report various negative A-CASI attitudes; however, some outcome-specific findings were also noted. Our research supports the feasibility and general acceptability of A-CASI with HIV-positive IDUs, and it suggests further research exploring the associations between A-CASI attitudes and characteristics of disadvantaged populations.
音频计算机辅助自我访谈（A-CASI）目前被广泛用于从包括注射吸毒者（IDU）在内的多种研究参与者那里收集信息。本研究的目的是描述参与干预试验的HIV阳性注射吸毒者如何看待A-CASI，并确定对A-CASI持负面态度的参与者的特征。通过对完成12个月评估的参与者样本（n = 821）进行研究，我们发现样本中的大多数（>80%）对A-CASI持积极或中立态度。约18%的人表示他们更喜欢与人面谈而非与计算机交流，12%的人表示他们不理解在计算机上听到的问题，14%的人表示计算机使得他们难以坦诚地谈论风险行为。多变量分析发现，社会边缘化程度更高（住房不稳定且赋权感较低）、身体限制更大且CD4细胞计数较低的参与者更有可能报告对A-CASI的各种负面态度；不过，也有一些特定结果的发现。我们的研究支持了A-CASI在HIV阳性注射吸毒者中的可行性和普遍可接受性，并建议进一步开展研究，探索对A-CASI的态度与弱势群体特征之间的关联。
