Table 2 Intervention Mapping for the HealthKick intervention

1: Needs assessment

Formative assessment (described below)

Members of the different planning groups embarked on a series of brainstorming sessions to determine and prioritise the key health problem/s, the behavioural and environmental factors related to the problem/s, and the determinants of these factors

2: Matrices of change objectives

Behavioural and environmental outcomes of the intervention were identified

Performance objectives were specified (required actions for achievement of outcomes)

Personal and external determinants identified for each performance objective to develop change objectives

(Change objective = performance objective + determinants)

Examples of change objectives given in Table 3

3: Theory-based methods and practical strategies

These were identified for change objectives; example given in Table 4

4: Producing programme components and materials

Programme components and materials described under 'Phase 2' were developed, and include the action planning process and toolkit

5: Planning programme adoption, implementation and sustainability

This step is currently underway and consultation with the Western Cape Education Department is key to this part of the process

6: Planning for evaluation

This step is currently underway and is described under 'Phase 3'
