Component Target Audience Setting Implementers Content Delivery
Radio adverts & Call-in Show Population in target areas, particularly caregivers of children under-five Broadcast on 3 radio stations: Komboni Radio, Radio 1 and Radio 4 Komboni Housewives and Radio Master of Ceremonies (MCs) Airing of three different spot adverts (EBF, HWWS, ORS + Zinc); similar content to that described in the forum & road shows skits. Call-in shows used as a discussion forum and to amplify the activities of the women’s forums (the timing of the shows coincided with the women’s forums). Discussions scripted around the target behaviours to test the callers' understanding of the intervention messages. Jingle about the target behaviours also played. 3 times a week for 6 months, with penetration in both intervention and control areas.
Komboni Housewives Women’s Forums ~20 caregivers of children under-five Forums held in the community at the home of a host (an intervention recipient) Komboni Housewives All four behaviours targeted using: 1) skits (feature the Komboni Housewives gossiping about mothers they believe are not practicing the correct behaviours, being proven wrong and welcoming the mother into their group); 2) discussion with question and answer sessions; 3) emotionally engaging demonstrations (designed to evoke feelings of disgust at mixed feeding a baby under six months and not handwashing with soap, and nurture in relation to incorrect preparation of ORS); and 4) short films featuring the Komboni Housewives (introduced partway through the intervention period). Activities were supported by banners, certificates, stickers, a branded bus and prizes (hats and T-shirts). One or two forums a day throughout intervention period; rotating between the eight intervention areas.
ORT Corner "Circle of mothers" sessions (with monthly prize draw) Caregivers of children under five (preferentially those with a child presenting with diarrhoea) At the ORT corner (where ORS solution is traditionally available) or another designated area in the government clinic in each intervention area Two Neighbourhood Health Committee Volunteers (NHCs) linked to the clinic in each site Circle of Mothers: content similar to forums designed to be shorter and focussed on exclusive breastfeeding and ORS and zinc. Every Monday-Friday at clinics in all 8 sites.
Prize draws: Winner of a hamper selected from all caregivers who attended the clinic session in the previous month. The Komboni Housewives conducted a mini forum at select prize draws. Monthly in each site. Attended by Komboni Housewives once per site.
Road shows All community members Large public space in each site MCs and Komboni Housewives (featuring a well-known local musician, Afunika) Large road shows, one in each intervention area. Similar content to the forums but energised by the presence of the MCs and the presence of Afunika who sang the campaign song and engaged the audience in discussion about the target behaviours. CDs featuring the campaign song as well as hat and T-shirts were given to those giving correct answers in a quiz. One road show in each site.
