Community based interventions increase knowledge scores and also have an impact of sexual behaviours with regard to HIV. However the problem remains as to how best to scale up these interventions and how best to overcome real or perceived barriers to their uptake. Community based interventions have multiple components and some will be more difficult to widen out than others. Those that involve face to face or one to one sessions will be most expensive and so most difficult to scale up. If some interventions can be implemented by means of custom computerized risk reduction programmes, then roll out on a large scale should be less problematic.
基于社区的干预措施可提高艾滋病相关知识得分，对性行为也有影响。然而，如何最佳推广这些干预措施以及如何克服其采用过程中的实际或感知障碍仍然是一个问题。基于社区的干预措施具有多个组成部分，有些部分比其他部分更难以扩大。那些涉及面对面或一对一会议的干预措施将最为昂贵，因此也最难扩大规模。如果某些干预措施可以通过定制的计算机化风险降低方案来实施，那么大规模推广应该不会有太大问题。
