Behaviorally Targeted Structural Interventions
E.g., conodm or clean syringe acces, treatment availability (&use & adherence). 100% Condom use program-Top Down. Community-led structural intervention. Mobilization of people and resources.

Systematic programs to support behavior change. -Typically a manual guides training & implementation. -more structured than an “evidence-based practice”
Adopted medical “product devlopment” model
-Vaccines, pharmaceuticals, devices.
Rigorous evaluation of risks and benefits
-At least one RCT, some say 2 RCTs
-Some say must be “replicated” by other teams
-Some say large-scale “effectiveness” trial needed
Recipient “Target Population” Risks
Diagnosed or Infected. High-Risk-Behavioral, genetic, & epidemiological risk factors. At-Risk-Potential for high-risk or infection if there is shift in behavior, envrinment, or epidemiology. Low-risk.
Address stigma & “victim blaming”
Intensity & Duration
Brief vs. Comprehensive. Sustaining ImpactGeneralizing Impact. Duration of behavioral changes. Breadth of behavioral changes
