Knowing one's serostatus is critical in the HIV prevention, care and treatment continuum. This study examines the impact of communication programs on HIV testing in South Africa. Data came from 2204 young men and women aged 16-24 who reported to be sexually active in a population based survey. Structural equation modeling was used to test the directions and causal pathways between communication program exposure, HIV testing discussion, and having a test in the last 12 months. Bivariate and multivariate probit regressions provided evidence of exogeneity of communication exposure and the two HIV-related outcomes. One in three sampled individuals had been tested in the last 12 months. Communication program exposure only had an indirect effect on getting tested by encouraging young people to talk about testing. The study suggests that communication programs may create an environment that supports open HIV-related discussions and may have a long-term impact on behavior change.
了解自身的血清学状态在艾滋病病毒预防、护理及治疗连续过程中至关重要。本研究考察了宣传项目对南非艾滋病病毒检测的影响。数据来自于一项基于人群的调查中2204名年龄在16至24岁之间且报告有性活动的年轻男女。采用结构方程模型来检验宣传项目接触、艾滋病病毒检测讨论以及在过去12个月内进行检测之间的方向和因果路径。双变量和多变量概率回归为宣传接触的外生性以及两个与艾滋病病毒相关的结果提供了证据。三分之一的抽样个体在过去12个月内进行过检测。宣传项目接触仅通过鼓励年轻人谈论检测对接受检测产生间接影响。该研究表明，宣传项目可能营造一个支持与艾滋病病毒相关的公开讨论的环境，并且可能对行为改变产生长期影响。
