The HIV/AIDS Prevention Practitioner Institute (HPPI) was created to empower HIV prevention professionals facing programmatic challenges and health disparities on the front line of the epidemic. HPPI consists of five interactive, multimedia, computer-delivered courses (and accompanying texts). The courses are designed to increase HIV health professionals' capacity to plan, evaluate, and sustain scientifically effective, culturally competent HIV prevention interventions. Each course in the multimedia HPPI series includes a video course guide, video segments with practitioners, quizzes, glossaries, workbook activities, and interactive learning exercises. Course 1: Developing a Program Model. defines and reviews the elements that make up a program model, explains how program models are used and what is involved in creating a program model, guides you through the specific steps for developing a program model and assessing its strength, and finally, explores strategies for assessing and improving the strength of your program model. Course 2: Program Replication and Adaptation. This course walks you through the steps required to select and adapt effective programs successfully. In particular, it addresses the following questions: 1. How do you identify effective programs? 2. How do you decide whether to replicate a program, and, if so, which one? 3. If necessary, how do you adapt a program to better meet the needs of your target population and setting? Course 3: Understanding Process Evaluation. This course focuses on strategies to assess an intervention program to see what is working and what is not, to determine what factors contribute to success or failure, and to refine the ways a program is im plemented. The course defines process evaluation, identifies key questions process evaluati on can answer, identifies uses of process evaluation findings, explains the steps necessary to conduct a process evaluation, and describes how a process evaluation can contribute to an outcome evaluation. Course 4: Understanding Outcome Evaluation. This course focuses on the most scientific way to determine if your program is having the desired positive impact on program participants' knowledge, attitudes, beliefs, skills, intentions, behaviors, or health status outcomes, such as prevention of HIV or sexually transmitted infection (STI). This course will help you: 1) Identify key research questions that can be answered by an outcome evaluation; 2) Understand the similarities and differences between outcome and process evaluations; 3) Understand the benefits of conducting outcome evaluations; 4) Implement the steps necessary to conduct a basic outcome evaluation; and 5) Understand why a comparison group is essential to outcome evaluation. Course 5: Creating Culturally Competent Programs. This course focuses on culture, cultural identity, and the importance of striving for cultural competence in your HIV prevention program. The course explores strategies for bringing cultural competence goals to bear on HIV/AIDS prevention program planning, implementation and evaluation processes.
