An implementation analysis conducted as part of a 2-year experimental study of residential and nonresidential treatment programs for the dually diagnosed homeless found significant differences in client engagement and retention, as well as unexpected variations in the treatment conditions. Fully 40 percent of subjects assigned to either treatment failed to become engaged for even one day, although a significantly higher percentage of those assigned to the residential program than the nonresidential program graduated from the first 3-month phase of treatment. The analysis revealed significant differences in the type and amount of services provided by the two treatment programs, as well as potentially important difficulties in program management. Such process data are valuable tools for understanding client outcomes and interpreting experimental results.
