The impact of motivational factors on AIDS high-risk behavior after pa
rticipation in an AIDS intervention program was explored among 208 out
-of-treatment injecting drug users (IDUs). It was hypothesized that lo
wer risk behavior would be evident at follow-up among IDUs who indicat
ed higher concern about their susceptibility to AIDS prior to interven
tion. Results showed that this motivational indicator predicted lower
risks 6 months after the intervention. Overall, this study indicates t
hat psychoeducational AIDS interventions will be most beneficial to in
dividuals with sufficient cognitive readiness to address drug-and AIDS
-related issues at a personal level. Assessments of risk and motivatio
n levels of program participants should be used to tailor intervention
strategies to meet individual needs.
