RESUMEN

BACKGROUND: Evidence-based interventions that are being delivered in real-world settings are adapted to enhance the external validity of these interventions. The purpose of this study was to examine multiple intervention adaptations made during pre-implementation, implementation, maintenance, and evolution phases of human immunodeficiency virus HIV prevention technology transfer. We examined two important categories of adaptations -- modifications to key characteristics, such as activities or delivery methods of interventions and reinvention of the interventions including addition and deletion of core elements. METHODS: Study participants were thirty-four community-based organization staff who were implementing evidence-based interventions in Los Angeles, California. Participants were interviewed twice and interviews were professionally transcribed. Transcriptions were coded by two coders with good inter-rater reliability (kappa coefficient = 0.73). Sixty-two open-ended codes for adaptation activities, which were linked to 229 transcript segments, were categorized as modifications of key characteristics or reinvention. RESULTS: Participants described activities considered modifications to key characteristics and reinvention of evidence-based interventions during pre-implementation, implementation, and maintenance phases. None of the participants reported accessing technical assistance or guidance when reinventing their interventions. Staff executed many of the recommended steps for sound adaptation of these interventions for new populations and settings. CONCLUSION: Staff reported modifying and reinventing interventions when translating HIV prevention programs into practice. Targeted technical assistance for formative evaluation should be focused on the pre-implementation phase during which frequent modifications occur. Continuous or repeated measurements of fidelity are recommended. Increased technical assistance and guidance are needed to ensure that reinventions are evaluated and consistent with the aims of the original interventions. Providing strategic technical assistance and written guidance can facilitate effective HIV prevention technology transfer of evidence-based interventions.

RESUMEN

OBJECTIVES: We examined implementation of evidence-based interventions for HIV prevention at community-based organizations in Los Angeles County, CA. METHODS: We conducted 2 waves of interviews with 34 organization staff members. We analyzed activities reported by staff in the phases (preimplementation, implementation, and maintenance and evolution) and activities defined by the technology transfer model for evidence-based HIV prevention interventions. RESULTS: Staff members were able to select, adapt, and implement evidence-based HIV prevention interventions despite challenges in each phase of technology transfer. Preimplementation challenges included lack of information and poor fit between the interventions and organizations' clients. Implementation challenges included retention of participants across intervention sessions and staff turnover. A challenge in the maintenance and evolution phase was enhancing staff skills in outcome monitoring and cost analyses. CONCLUSIONS: Technical assistance must be matched to the specific challenges found in each phase of technology transfer. Successful transfer of evidence-based HIV prevention interventions will depend on their continued uptake and use by organization staff. This study highlights directions for improving communications regarding appropriate modifications to these interventions and for organizational planning to continue adapted interventions.

RESUMEN

BACKGROUND: Methamphetamine-dependent gay and bisexual men (GBM) are at high risk for HIV transmission, largely due to drug-associated sexual risk behaviors. This project evaluated the efficacy of four behavioral drug abuse treatments for reducing methamphetamine use and sexual risk behaviors among this population. METHODS: In this randomized controlled trial, 162 methamphetamine-dependent (SCID-verified) GBM in Los Angeles County were randomly assigned to one of four treatment conditions for 16 weeks: standard cognitive behavioral therapy (CBT, n=40), contingency management (CM, n=42), combined cognitive behavioral therapy and contingency management (CBT+CM, n=40), and a culturally tailored cognitive behavioral therapy (GCBT, n=40). Stimulant use was assessed thrice-weekly during treatment using urine drug screens (48 measures). Sexual risk behaviors were monitored monthly (four measures). Follow-up assessments were conducted at 6 (80.0%) and 12 months (79.9%). RESULTS: Statistically significant differences in retention (F(3,158)=3.78, p<.02), in longest period of consecutive urine samples negative for methamphetamine metabolites (F(3,158)=11.80, p<.001), and in the Treatment Effectiveness Score were observed by condition during treatment (F(3,158)=7.35, p<.001) with post hoc analyses showing the CM and CBT+CM conditions to perform better than standard CBT. GEE modeling results showed GCBT significantly reduced unprotected receptive anal intercourse (URAI) during the first 4 weeks of treatment (X2=6.75, p<.01). During treatment between-group differences disappeared at follow-up with overall reductions in outcomes sustained to 1-year. CONCLUSIONS: Among high-risk methamphetamine-dependent GBM, drug abuse treatments produced significant reductions in methamphetamine use and sexual risk behaviors. Drug abuse treatments merit consideration as a primary HIV prevention strategy for this population.

RESUMEN

As treatments have improved health and quality of life for people with HIV/AIDS, many have contemplated workforce reentry. Workforce reentry rarely occurs among people with illness-related disability. The authors mailed a survey that included workforce-entry-related concerns to 1,991 HIV/AIDS clients. Factor analysis extracted 6 areas of concern (benefits loss, work-related health, job skills, discrimination, personal health care, workplace accommodation). Levels of concern generally increased with HIV acuity level and time since last worked. Work-related health concerns predicted consideration of workforce entry, and work-related health concerns and benefits-loss concerns predicted estimated time to return to work. Findings provide quantitative validation of intuitive categories of workforce-entry concerns among people with HIV/AIDS and suggest that concerns may shift with progress toward workforce entry.

RESUMEN

This study examined the joint impact of gender and ethnicity on expectations of general discrimination against oneself and one's group. According to the double-jeopardy hypothesis, women of color will expect to experience more general discrimination than men of color, White women, and White men because they belong to both a low-status ethnic group and a low-status gender group. Alternatively, the ethnic-prominence hypothesis predicts that ethnic-minority women will not differ from ethnic-minority men in their expectations of general discrimination because these expectations will be influenced more by perceptions of ethnic discrimination, which they share with men of color, than by perceptions of gender discrimination. All results were consistent with the ethnic-prominence hypothesis rather than the double-jeopardy hypothesis.
