The first PRS efficacy
review included studies published between 1988 and 1996
and resulted in the identification of 24
evidence-based interventions. These
interventions were summarized in the
Compendium of HIV Prevention Interventions
with Evidence of Effectiveness
(CDC, 1999) [1].
This review was updated a few years later to
include studies published up to the year
2000 and resulted in identifying an
additional 8 evidence-based interventions
(Kay et al., 2003) [17].
As the United States
has entered the third decade of the HIV/AIDS
epidemic, HIV behavioral intervention
research has matured and become more
rigorous. To reflect the scientific
progress in the field, in 2004, the PRS team
strengthened its efficacy criteria for
evaluating individual- and
group-level behavioral interventions (Lyles et al., 2006)
[18]. PRS
recently completed a review of the HIV prevention research literature published
between 2000 and 2004 using these revised efficacy criteria. This review resulted
in the identification of 18 best-evidence
and 10 promising-evidence individual- and group-level behavioral interventions
(Lyles et al., 2007) [19].
The efficacy review is an ongoing process to identify evidence-based HIV behavioral interventions as quickly as possible after publication. PRS updates this website periodically to provide timely information to the HIV prevention field. The most recent update, through May 2008, added an additional 5 best-evidence and 3 promising-evidence interventions for a total of 36 best-evidence and 21 promising-evidence ILIs and GLIs. PRS is currently reviewing community-level interventions and will report on those findings as soon as the review is completed.
