One definition of Narrative Therapy is:
Narrative therapy holds that our identities are shaped by the accounts of our lives found in our stories or narratives. A narrative therapist is interested in helping others fully describe their rich stories and trajectories, modes of living and possibilities associated with them. At the same time, this therapist is interested in co-investigating a problem's many influences, including on the person herself and on her chief relationships. By focusing on problems' effects on people's lives rather than on problems as inside or part of people, distance is created. This externalization or objectification of a problem makes it easier to investigate and evaluate the problem's influences. Another sort of externalization is likewise possible when people reflect upon and connect with their intentions, values, hopes, and commitments. Once values and hopes have been located in specific life events, they help to “re-author” or “re-story” a person's experience and clearly stand as acts of resistance to problems. The term “narrative” reflects the multi-storied nature of our identities and related meanings. In particular, re-authoring conversations about values and re-membering conversations about key influential people are powerful ways for people to reclaim their lives from problems. In the end, narrative conversations help people clarify for themselves an alternate direction in life to that of the problem, one that comprises a person's core values, hopes, and life commitments. That said, along the way a narrative conversation turns to the socio-political sources of problems such as destructive assumptions about gender roles. People find it useful to know that problems are much larger than themselves, and to realize that those problems are constantly fed by society.
