Table 1 presents the matrix of intervention objectives for two performance objectives.
Subsequently, we further specified programme objectives by creating a matrix of change objectives.
Step 2, Tasks 3 and 4 focus on CWH and are used to select changeable behaviour determinants of performance objectives for the behavioural and environmental outcomes with a matrix of change objectives being created that links the determinants to performance objectives.
Performance objectives were subsequently defined and crossed-referenced with the predictors to develop a matrix of change objectives.
G. Peters (2014) provides concrete guidelines for these tasks, resulting in the so-called matrix of change objectives (see Table 1).
Selected examples of the matrix of change objectives are shown in Table 2.
Finally, a matrix of change objectives was developed for each behavioural outcome.
The result of this process was a matrix of change objectives detailing what would be addressed in the maintenance programme.
In Additional file 1 we present a matrix of performance objectives crossed with the individual and environmental determinants.
The POs are crossed with relevant determinants in order to create a matrix of change objectives (COs) [ 44].
If proposed adaptations include the addition of behaviors, environmental conditions, determinants, and change methods, then planners can create a separate matrix of change objectives with the behavior or environmental condition being targeted and its determinants.
