We have noted that, in our view, when undertaking any psychotherapy there should be supervision and reflective practice throughout one’s career. Senior therapists can be as much in need of discussions about their cases as newly qualified practitioners. Until we have much improved our understanding of what intervention works for which patient and how, we recommend supervision as a key clinical tool in learning the skills and techniques of BPI. Of course, we do not yet know which of these tips is responsible for clinical effectiveness. Therefore, regular fortnightly supervision with a senior, more experienced colleague is sound practice. Table 9.1 describes key general components that should activate a discussion with your supervisor.
