The final part of the intervention focuses on the behavioural domain and is primarily concerned with practice and exposure. During this stage the child learns to apply their new skills to successfully face and overcome the situations they find challenging and anxiety-provoking. The child is encouraged to systematically approach and confront situations they previously avoided in a stepped way that maximises the likelihood of success. This may involve a number of methods including problem-solving, the development of graded hierarchies, in vivo and imaginal practice, behavioural experiments and positive reinforcement (Figure 10.1).
