Intervention Methods

In order to advance its mission, SIG uses several different types of intervention methods such as digital, microfinance, and couple based.

Digital Intervention

Defined as the integration of text, audio, video, still images, animation and interactivity, multimedia has become ubiquitous as an innovative method to enhance learning.  The Social Intervention Group develop, test and disseminate prevention programs that integrate multimedia to best meet adult learning needs as well as to prepare for rapid scale up efforts for widespread access. Research has shown that  digital intervention has been an effective way of disseminating information and improving active learning by:

  • Interactive games with high speed graphics to increase attention
  • Four characters (fictional role models) are used throughout the sessions to increase emotional engagement and facilitate positive peer norms
  • Use of storytelling by the four characters
  • Modeling of core skills by the fictional characters is followed by role play to increase intention and motivation to use skills
  • Individual activities are recorded in an electronic log that participant may or may not share with group, which ensures confidentiality
  • Electronic journal logs allow participants to systematically track and document progress

Several studies have shown microfinance to be an effective structural HIV prevention strategy for women engaged in sex work (Odek et al., 2009; Pronyk et al., 2008; Pronyk et al., 2006; Erulkar et al., 2006; Sherman et al., 2006; Cordisco-Tsai, et al., 2011). Under Social Intervention Group leadership, investigators at the Global Heath Research Center are pioneering new models for combining microfinance with HIV prevention and other health risk outcomes.  Undarga, our first model, tested an asset-based model for microfinance for women engaged in sex work in Mongolia. The model is sensitive to the unique needs of women engaged in sex workers, who are stigmatized and often unable to gain access to traditional financial institutions, by providing financial literacy training prior to business development trainingand by providing matched savings to build assets towards business development.
