Most commonly relationship issues are dealt with within a therapeutic framework, which is often appropriate. However, therapy is not always necessary or relevant and it may prevent some people from getting the support they need. This chapter presents pioneering thoughts about the role of coaching in relationship settings, including singles struggling to form or secure a lasting relationship, couples seeking a more satisfying relationship, parents struggling to manage effective relationships with their children, and relationship issues during a midlife crisis. A coaching approach is focused on helping people to identify where the issue lies and to develop strategies to work around it, which can be highly effective in supporting people to achieve many important relationship goals. The chapter begins by setting out the key principles and features of relationship coaching, continues with a summary of key theories particularly relevant to the field, with the remainder of the chapter dedicated to an overview of key applications of relationship coaching combining theory and practice.
