Bringing it all together: Modeling intervention processes using structuralequation modeling

The combination of programmatic theory and structural equation modeling (SE M) can act as the basic intellectual machinery for designing and evaluating behavioral interventions. As an example of the integration, we consider a case study of a randomized experiment to reduce sexual risk taking, the WIN GS Project. Barriers to combining systematic use of SEM with programmatic t heory for program improvement and assessing program effectiveness are also discussed.
