Mapping group interventions to contexts and health outcomes: characteristics and assumptions
| Intervention type | Relevant target population | Assumption 1: Support | Assumption 2: Behaviours | Assumption 3: Problem-solving | Examples of outcomes achieved |
| Classroom | Individual group members | Individuals can change risk factors largely on their own | Bottleneck behaviours and their enablers and barriers can reliably be identified by experts | Few problem-solving capacities are required; group members only need to follow instructions | Improved knowledge of and attitudes towards tapeworm infection among targeted school children31 |
| Club (didactic) | Group members | Support from staff and group members suffice to change risk factors | As above | As above | Improved uptake of antenatal and postnatal care services among group members32 |
| Club (problem-solving) | Group members | As above | Bottleneck behaviours are disputed or unknown to experts | Group members are willing and able to collectively reflect, innovate and adapt to address health issues with facilitators | Greater utilisation of latrines among club members33 |
| Collective | The general population | Collective action by staff, group members and the wider community is needed to change risk factors | As above | Group and community members are willing and able to reflect, innovate and adapt to address health issues with facilitators | Improved population-level rates of newborn survival8 |
