Determinants of subject compliance within an experimental anti-HIV drug protocol

A study of subject compliance within an experimental anti-HIV drug protocol was conducted with 40 asymptomatic HIV seropositive persons participating in a double-blind, placebo controlled trial of the effectiveness of ZDV. Subject compliance was assessed through the use of study nurse independent ratings. The 20 most compliant and 20 least compliant subjects were surveyed at a 6-month interval using self-report instrument designed to assess perceived social support and other psychosocial factors thought to effect compliance. Results indicated that more adherent subjects lived further from their treatment site, did not live alone, saw their study nurse as supportive, and were more likely to depend on a significant other for a wide range of social, economic, and emotional support. Implications for the practical use of these findings are discussed and suggestions for future research are proposed.
