In this chapter, I will consider how to deal with the central mechanism in the form of problematic cognitions that account for the client’s target problem. Here, you will wish to use your preferred CBT approach. If you hold to the view that these problematic cognitions are best modified, you will use your preferred strategies, mindful of the constraints on your time that SSI-CBT imposes. If you believe that such cognitions need to be mindfully accepted as a prelude to value-based action, you will use appropriate metaphors and in-session demonstrations to implement this strategy. Or perhaps, you practise a mixed approach and consider that the main issue is when to encourage clients to modify their problematic cognitions and when to encourage them to accept these cognitions in a mindful way. In what follows, I outline and demonstrate my approach to the issue.
