HIV Prevention in the CTN
In last decade, 5 large-scale HIV-related
protocols have been conducted addressing
effectiveness and feasibility questions
Screening, Evaluation, and Treatment of
HIV/AIDS, Hepatitis C, and STIs (N=2,040)
Reducing HIV-Related Risk Behaviors among
IDUs in Residential Detoxification (N=632)
HIV/STI Risk Reduction Intervention for Women
(N=515)
HIV/STI Risk Reduction Intervention for Men
(N=590)
HIV Rapid Testing and Counseling (N=1,281)
HIV Risk in Women
Heterosexual women are among the fastest
growing subgroups of people with HIV in the
US
Women comprise 27% of new HIV
infections; 80% via heterosexual
transmission (CDC, 2008)
African American and Latina women at
disproportionate risk
Women at greatest risk through primary
male sexual partners (St. Lawrence et al.,
1998; Weiss, 2000)
Critical factors associated with HIV risk and
substance use
Features of Effective HIV
Prevention Interventions For
Women
Gender-specific
Comprehensive, includes skills-building
4 or more sessions
Prendergast et al., 2001; Semaan et al., 2002; Exner et al., 1997
Safer Sex Skills-Building
(SSSB) HIV Risk Reduction
Intervention
Session 1: HIV/STI information, testing
& counseling
Session 2: Personal risk assessment,
triggers, supports
Session 3: Condom skill building,
problem-solving
Session 4: Negotiation
Session 5: Slips, review, and graduation
Theory
Social Cognitive Learning Theory
Behavior is learned through the social
processes of observation, modeling,
skill rehearsal, and feedback, especially
with one’s peer group
Empowerment Theory
Individuals are empowered to action by
the processes of skill mastery, peer
support, and ability to impact on one’s
world
Underlying Principles
Expected outcomes of behavior
Skills & Self-efficacy
Personal goals
Partner risk assessment/Safety

Summary
Significant difference in the effect of
SSSB over time compared to HE at 6month follow-up; this effect is enhanced
by treatment completion
Monogamy status was a significant
predictor of USO; women with only one
male partner reported 33% more USO
than women with more than one male
partner

Secondary Analysis:
Drugs with Sex Occasions
Mixed Effects Model
Random: Subject
Fixed: Treatment, Time
Covariate: program type, monogamy,
baseline drugs with sex occasions
Zero-inflated Negative Binomial
distribution
Intervention Effect on
Drugs with Sex Occasions
At 6-month follow up there was a
significant difference in the number of
drug or alcohol with sex occasions
favoring SSSB (p<.03)
Predicted number of drug with sex
occasions at 6-month:
SSSB=6.52 (-17 from baseline)
HE=14.85 (-12 from baseline)
Summary
Similar pattern to unprotected sex
outcome: although drugs with sex
occasions decreased for both groups at 3month follow up, reductions continued at 6month for the SSSB group.
No differences between SSSB and HE on
substance use or injection drug use
outcomes
Post-study Provider Attitude
Survey
Post-Study Provider
Survey Methods
Administered to clinical providers and
program directors (N=116) to assess
attitudes towards clinical and service
impact and research impression
Respondents participated in both the
women’s and men’s HIV Risk Reduction
Studies (15 programs)
Examples of Attitudes and
Perceptions
Clinical Impact
Identified extra clinical problems
Helped make me a better clinician
Increased discussion of sexual issues
Research Impression
Increased awareness of research
procedures
Disrupted day to day operations
Researchers only people to benefit
Survey Findings
Staff who directly participated reported:
Intervention components as more useful
Increases in HIV testing/referrals at site
However, those directly involved in the
studies reported less positive attitudes
regarding clinical impact and research
Higher study attendance rates
corresponded to better clinical impact
attitudes (men only)
Campbell et al., 2012
Implications
Implications for Social Work
Findings support the use of
comprehensive HIV risk reduction
interventions to
Reduce unprotected sexual acts
Reduce sexual acts while intoxicated
The persistence of reduction in sexual
risk among SSSB clients is encouraging
Primary partnerships and femalecontrolled methods of protection are
critical components for women
Implications for Social Work
Brief, evidence-based, HIV interventions
can be implemented into substance
abuse treatment work with focused
training and ongoing support
But require better integration within
program curriculum to address
attendance issues and sustainability
Implications for Social Work
Effectiveness trials can address
important adoption and
implementation issues (training,
acceptability, feasibility, client
outcomes)
But they are only part of the solution to
the research/practice gap
And can be improved upon to better
support providers and promote
sustainability
Implications for Social Work
Issues of cost effectiveness and
reimbursement must be a primary
focus of effectiveness studies
Positive study outcomes and
perceived intervention usefulness
are not sufficient
Evaluation of adoption,
implementation, and maintenance
efforts and barriers remains critical
