USING FACTORIAL SURVEYS FOR DESIGNING INTERVENTION PROGRAMS

This article reviews factorial surveys and highlights their utility in designing intervention programs. It then describes two instances in w hich factorial surveys were used to develop HIV/AIDS-related intervent ions: designing HIV vaccine trials that maximize participation and ide ntifying optimal treatment regimes for HIV positive mothers and their babies to prevent perinatal HIV infection. We conclude that factorial survey applications of this kind have a great potential for use in the design (and redesign where necessary) of intervention programs.
