While overall HIV prevalence in Malawi has decreased, it is still high in the southern region of the country. Behavioral prevention activities are crucial to continue the reduction in HIV prevalence. Behavior change is influenced by many factors. Previous work indicates knowledge about HIV transmission, self-efficacy to protect oneself from exposure, and accurate risk perception of one's susceptibility all impact sexual behavior. The current study looks at the effects of a behavior change communication program in Malawi called the BRIDGE II Project on psychosocial and behavioral variables. The program sought to address barriers to individual action and confront societal norms related to sexual risk behavior through a mix of community-based activities and mass media messages delivered through local radio stations. Using cohort data (n = 594), we examined the effect of BRIDGE exposure on three variables that affect HIV behaviors: knowledge, self-efficacy, and risk perception, as well as two behavioral outcomes: HIV testing and condom use at last sex. Data were collected at baseline and for a midterm evaluation. Regression analyses showed exposure to BRIDGE was significantly associated with knowledge level (β = 0.20, p < .001) and self-efficacy (β = 0.35, p < .001) at midterm when controlling for baseline scores, but not risk perception. Psychosocial variables did not show a significant relationship to either behavioral outcome. However, program exposure was a significant predictor of both HIV testing in the past year (odds ratio [OR] = 1.40, p < .001) and condom use at last sex (OR = 1.26, p < .05). This study suggests such a communication intervention may play an important role in not only affecting HIV-related behaviors themselves, but also critical factors that affect HIV behaviors, including knowledge and self-efficacy. It is recommended that communication efforts around HIV risk reduction be increased.
虽然马拉维的整体艾滋病毒流行率有所下降,但该国南部地区的流行率仍然很高。行为预防活动对于持续降低艾滋病毒流行率至关重要。行为改变受到多种因素的影响。先前的研究表明,关于艾滋病毒传播的知识、保护自己免受感染的自我效能感以及对自身易感性的准确风险认知都会影响性行为。当前的研究考察了马拉维一个名为“桥梁二期项目”的行为改变沟通项目对心理社会和行为变量的影响。该项目试图通过一系列社区活动以及通过当地广播电台传播的大众媒体信息,来解决个人行动的障碍并应对与性风险行为相关的社会规范。我们使用队列数据(n = 594),研究了接触“桥梁项目”对影响艾滋病毒相关行为的三个变量(知识、自我效能感和风险认知)以及两个行为结果(艾滋病毒检测和最近一次性行为时使用避孕套)的影响。在基线期和中期评估时收集了数据。回归分析表明,在控制基线分数的情况下,中期时接触“桥梁项目”与知识水平(β = 0.20,p <.001)和自我效能感(β = 0.35,p <.001)显著相关,但与风险认知无关。心理社会变量与任何一个行为结果均未显示出显著关系。然而,项目接触是过去一年艾滋病毒检测(优势比[OR] = 1.40,p <.001)和最近一次性行为时使用避孕套(OR = 1.26,p <.05)的显著预测因素。这项研究表明,这样的沟通干预不仅可能在影响与艾滋病毒相关的行为本身方面发挥重要作用,而且在影响包括知识和自我效能感在内的影响艾滋病毒行为的关键因素方面也可能发挥重要作用。建议加大围绕降低艾滋病毒风险的沟通力度。
