Assessment of HIV risk.

Based on the review of existing instruments and analysis of problems encountered in clinical and research practice with one of the most commonly used assessment instruments, the RAB, this paper proposes a number of solutions aimed at improving validity, and efficiency of assessment of HIV risk in drug abusing populations. Briefly, five domains of assessment are discussed: intravenous drug use, high-risk sexual behaviors, knowledge of HIV transmission and methods of prevention, psychological aspects of behavioral change, and epidemiological factors of HIV transmission. The paper discusses also changes in format, scope, and context, as well as scoring procedures that may improve discriminability and sensitivity to detect change of a comprehensive HIV risk assessment instrument. Finally, a process of developing an HIV risk assessment instrument, the ARI-I, which is based on the proposed recommendations and which incorporates methodological improvements discussed in the paper is briefly described.
