The ‘Bridging the Gap: IEC 4 LGBTI’ Handbook has been developed to support organisations working with lesbian, gay, bisexual, transgender and intersex (LGBTI) people in southern Africa to develop effective IEC materials. Recognising and addressing the needs of LGBTI in southern Africa is a relatively new field for many organisations. The need to do so has, in part, come about because of the identified lack of adequate access to information and services specifically for LGBTI people, to support them to protect their health and the health of others - particularly given that southern Africa is the region with the highest HIV prevalence worldwide. Being a relatively new field of programming, and because the rights of LGBTI are not legally recognised in many southern African countries, the development and dissemination of IEC materials specifically targeting LGBTI has been limited and there has been relatively little capacity strengthening, documentation or information sharing around the development of effective IEC materials targeting these important groups. This Handbook aims to provide a guide to a systematic IEC material development methodology, particularly IEC materials for LGBTI - and other at-risk and hard-to-reach groups - to strengthen IEC material development for LGBTI in the region, and promote lesson learning and sharing around HIV, sexual and reproductive health (SRH) and broader health issues.
