Materials in the Community Conversation Toolkit include a facilitator’s guide, community mobilizer’s cards, roleplay cards, storytelling finger puppets, promotional proverbs and best kept secrets throw boxes, promotional playing cards, and dialogue buttons. These interactive formats are designed to mobilize adults aged 20 and above in communities to take action toward HIV prevention. The toolkit is intended to complement existing HIV prevention activities and address several key drivers: concurrency, cross-generational sex, gender-based violence, and alcohol abuse. The toolkit was developed by FHI 360 under the C-Change Project by Soul City Institute for Health and Development Communication. Soul City led the adaptation of the toolkit in Zambia, Zimbabwe, Namibia, and Malawi. Soul City's in-country partners have conducted pretests and consultations with stakeholders in each of the countries. Each material in the toolkit was tested with community mobilizers and men and women ages 20 and above in community. Sixty-nine focus group discussions and 34 in-depth interviews were conducted with men and women and with trained community facilitators who lead discussions using the materials. The toolkit has also been adapted in Lesotho, Nigeria, and Swaziland and is available in 10 languages.
