Increases in HIV prevalence indicate ongoing need for HIV interventions. A brief manualized intervention called TCU which addresses multiple HIV risks, was further evaluated to determine how it addressed individual's knowledge deficiencies in the assessed risks. The sample of 1256 offenders in 8 correctional substance abuse treatment programs participated either in treatment as usual (TAU) or TCU . From multivariate multi-level analysis, was more effective in improving the greatest need area, whether knowledge, motivation, or confidence regarding HIV risky behaviors. Findings underscored the importance of addressing HIV risk areas with greatest need for change and strengthens previous findings of the intervention's potential for individuals with varying HIV risks.
