Community-based organizations and public health departments have historically applied for and received funding to implement a variety of HIV prevention interventions, but it is unclear how they make decisions regarding which interventions to implement or whether their agency has sufficient capacity and/or resources to effectively carry them out. Assessment activities can play a valuable role in helping agencies make these decisions by providing information to better target services. Recent funding efforts supporting the Diffusion of Effective Behavioral Interventions Project and other evidence-based approaches for HIV prevention require that agencies possess basic skills to effectively conduct individual-, group-, or community-level interventions, as well as the specific activities associated with an evidence-based intervention (EBI). We examine the link among community assessment, agency capacity, and intervention effectiveness, and provide resources to better guide programs in assessing their communities and organizations in order to implement the most effective EBI.

Efficacious behavioral interventions developed to address the spread of HIV/STIs are currently being disseminated in the USA through a national diffusion program (DEBI) spearheaded by the Centers for Disease Control and Prevention (CDC). Understanding how interventions are translated to real world settings is necessary to further scientific knowledge of this process and to facilitate future translation efforts in public health. Prior studies have begun to elucidate how agencies translate behavioral interventions into practice, but further work is needed. Guided by the ADAPT framework, we examined agencies’ assessment, preparation, and implementation of interventions. Our qualitative interview-based study focused on six community-based agencies in California (United States) funded to implement three group-level HIV interventions. Findings showed considerable variation in the extent to which agencies engaged in assessment and broad-based preparation and in the ease with which agencies implemented the interventions. The findings provide insight into the process that agencies undergo in the translation of effective behavioural interventions and illustrate how agencies can inform logic models that guide translation. We also identify relevant dimensions of existing models, including the ADAPT framework and Roger’s (1995 and Roger’s (2005) diffusion of innovations in organizations, that have value for agencies that are translating research to practice.

Behavioral science theory is recommended as a basis for prevention programs, yet many STD/HIV prevention providers have little academic background in this area and see no relevance of theory to their work. This study assessed STD/HIV prevention providers' intuitive insight about behaviors. Comparisons of behavioral determinants from providers "common sense" theories with determinants identified in formal theories are made through the use of Theoretical Domains, a teaching tool designed to enhance the understanding and use of behavioral science in planning and implementing interventions. Understanding how to effectively apply behavior change concepts, combined with prevention providers' basic, intuitive knowledge can enhance understanding, communication, and skills exchange between providers and researchers. Building capacity in local communities begins with a participatory process of community members, prevention providers, and researchers working together as equal partners. Better translation of research into practice using theory-based interventions will benefit the field of STD/HIV prevention.

Over the last decade, the Centers for Disease Control and Prevention's Diffusion of Effective Behavioral Interventions (DEBI) program funded several hundred community-based organizations (CBOs) and health departments in a wide-scale HIV prevention national diffusion effort. We interviewed six California agencies funded to implement one of three group-level DEBIs to identify facilitators and/or challenges to effective implementation. We identified several social and structural factors affecting community members' participation in DEBIs, including language issues, stigma associated with HIV and sexual orientation, homelessness, and incarceration. Age, class, and socioeconomic status also significantly influenced member participation and CBO implementation success. Although changing individual behaviors is the ultimate measure of behavioral intervention/DEBI success, attention must be given to the larger social and structural factors that significantly affect risk for HIV. In fact, the National HIV/AIDS Strategy recognizes these factors as major barriers to HIV prevention and has developed recommendations that address health disparities. We present short-term, intermediate, and long-term strategies addressing social determinants of health and offer suggestions for adapting DEBIs to meet the broader needs of persons prioritized for DEBIs.
