The current research tests stage-sequential models of safer sexual behavior using a new method for data analysis called Latent Transition Analysis (LTA). Results are presented from data collected on 359 injection drug users participating in a seroconversion study conducted by the UCLA Drug Abuse Research Center. We identified a six-stage model that adequately represented the data. Results indicate that respondents moved back and forth among high, medium, and low risk stages. This finding highlights the need for continual, sustained interventions to help maintain safer sex and drug-using behaviors in high-risk groups.
当前的研究使用一种名为潜在转换分析（LTA）的新数据分析方法来测试安全性行为的阶段序列模型。结果来自于对359名参与加州大学洛杉矶分校药物滥用研究中心进行的血清转化研究的注射吸毒者收集的数据。我们确定了一个能充分体现这些数据的六阶段模型。结果表明，受访者在高、中、低风险阶段之间来回变动。这一发现凸显了持续进行干预以帮助高危人群维持更安全性行为和吸毒行为的必要性。
