Project Details


A five-year collaborative IRPG project is proposed in response to Program
Announcement 94-054, "Strategies to Reduce HIV Sexual Risk Practices in
Drug Users." The research program in Miami, Florida will focus on
developing and implementing sexual risk-reduction interventions targeting
injecting drug users and their sex partners not currently in drug
treatment who are at increased risk of HIV infection/transmission as a
consequence of their drug/sexual practices.

The research study will be conducted in two phases. The first phase will
consist of two sub-phases, 1A and 1B, which together will assess the
individual, social, and environmental context of sexual risk behavior and
sexual risk reduction, and inform the development of interventions to
reduce sexual risk in targeted drug-user populations. Phase 1A will elicit
in-depth qualitative information about behavioral and normative beliefs,
barriers and facilitators, and social influence and network factors
related to sexual risk reduction. In Phase 1B, a comprehensive interview
instrument about specific risk-reducing sexual behaviors and their
antecedents will be developed and administered, guided by data collected
in Phase 1A. Additionally, a formalized behavioral context study of
sexual risk-reducing behaviors will be conducted with injecting drug users
and their sexual partners.

Based on information gained in Phase 1, theory-driven, empirically
informed interventions will be developed and evaluated in a randomized
field experimental design for use during Phase 2. The Miami intervention
is a sequenced and additive model in which three types of interventions
will be compared: l) an individual counseling intervention , 2) a couple
counseling intervention, and 3) a network-based intervention.
Intervention strategies will be guided by the empirically derived
framework of behavior change readiness. Randomization will provide the
opportunity to measure the additive effects of dyad to individual
counseling and of individual counseling + dyad counseling to network
counseling. The three types of interventions will be sequenced in order to
measure the separate effects of each intervention type.

Although the stated research objectives will be substantially realized by
the study design set forth in this proposal for Miami, FL, the value of
the proposed initiative will be greatly enhanced by an expected
collaboration with six other sites (Phoenix, Arizona; Houston, Texas; Long
Beach, California; Miami, Florida; New Orleans, Louisiana; and Washington,
D.C.) that propose to conduct independent complementary studies for
development of sexual risk-reduction interventions within the same
theoretical and analytical framework. Each collaborating site will develop
unique interventions targeting local populations that will be compared
with a standardized control intervention that is uniform across sites.
Monitoring of sites (site visitors by the executive committee) will help
ensure quality control for intervention integrity, and for data management
and analyses.
