Concept maps can be developed both during and at the end of the qualitative data collection phase to represent connections between findings. Two concept maps should be developed: one to represent findings between barriers; and one to represent findings between boosters.
The relationships between different barriers and boosters can include a number of different "types" of relationships. These include (but are not limited to) 'contributes to', 'required for', 'encourages', 'helps create', 'results in' and 'allows'.
Image 1 is an example of a concept map using a few of the different types of relationship:

They are useful during a SQUEAC investigation for a number of reasons:
- During interviews when working out and communicating how different barriers and boosters are related and interact with each other in complex or cyclical processes. Image 1 shows a virtuous circle where the different boosters reinforce themselves resulting in favourable results. Image 2 shows a vicious circle which drives coverage down.
- During qualitative data collection, concept maps can also help the survey team to form hypotheses for further investigation.
- Once qualitative data collection has been completed, concept maps can be useful for scoring findings to estimate overall programme coverage (more guidance to follow).
