Community Mobilisation - 19.8% vs. 14.3% Virally Suppressed


Strategy researched

Engaging in community mobilisation activities, harnessing networks for message dissemination, and forging organised community action

Impact achieved

As compared with men in the control villages, men in the intervention villages were more likely to know their status (44.9% vs 36.9%), be on antiretroviral therapy, or ART (26.1% vs 20.4%), and be virally suppressed (19.8% vs 14.3%). Similar differences were observed between intervention and control village women. In absolute terms, these proportions translate into 200 more residents who are virally suppressed in the intervention communities versus control communities, which could lead to stark differences in rates of new infections.

Country of study

South Africa

Research methodology

Cluster RCT with 8 intervention communities (n=20,544 residents) and 7 control communities (n=17,848)

Journal paper title and link

A community mobilisation intervention to improve engagement in HIV testing, linkage to care, and retention in care in South Africa: a cluster-randomised controlled trial

Excerpt from Abstract

"Among women, HIV testing increased quarterly by 10·6% (RC 1·106, 95% CI 1·097 to 1·114, p<0·0001) in the intervention communities and 9·3% (1·093, 1·084 to 1·102, p=0·053) in the control communities; increases were greater in intervention communities (exponentiated interaction coefficient 1·012, 95% CI 1·001 to 1·023, p=0·043). Quarterly linkage increased significantly among women in the intervention communities (RC 1·013, 95% CI 1·002 to 1·023, p=0·018) only."

Your Priorities, Opportunities and Challenges? Complete the SURVEY

Why the focus on direct impact data?

A common challenge from policy makers, funders, community members, people directly experiencing development issues, and governments is: Demonstrate your Impact. Prove that what you are doing works. The high quality, highly credible data presented on the cards below is designed to help you answer that question for your social change, behaviour change, community engagement, communication and media for development, strategy formulation, policy engagement and funding initiatives. At this link filter the research data to your specific interests and priorities

Why a playing cards design?

There is a physical pack of cards with this data (to get a copy please request through the comment form for any card). The card approach allows for easy identification and selection of relevant direct impact data in any context. For example if talking with a donor and you need to identify proof of impact say "take a look at the 7 of Hearts". Quick access can be provided to high-quality data for many areas of your work – funding, planning, policy, advocacy, community dialogue, training, partner engagement, and more. A card deck is also engaging, easy to use and share, a conversation starter, and a resource - and they are fun and different. So we kept that design for the online images as it can serve similar purposes. 

What are the criteria for inclusion?

The impact data presented meets the following high standard for inclusion criteria:

  • Positive change or trend in a priority development issue;
  • Social change or behaviour change strategy or process;
  • Randomized Control Trial or Systematic Review methodology;
  • High quality peer review journal published;
  • Numeric impact data point
  • Published since 2010.
