Wed, 04/05/2023 - 08:32

Strategy researched

Behaviour-based sexual assault prevention intervention in informal settlements involving classroom-based separate training sessions for girls and boys

Impact achieved

Researchers estimate a 3.7% decrease, p = 0.03 and 95% confidence interval (CI) = (0.4, 8.0), in risk of sexual assault in the intervention group due to the intervention (initially 7.3% at baseline). They estimate an increase in mean generalised self-efficacy score of 0.19 (baseline average 3.1, on a 1-4 scale), p = 0.0004 and 95% CI = (0.08, 0.39).

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.
