When people recover from depression via psychotherapy, their attributions about recovery are likely to be different than those of people who have been treated with medication. Psychotherapy is a learning experience. Improvement is not produced by an external substance, but by changes within the person. It is like learning to read, write or ride a bicycle. Once you have learned, the skills stays with you. People no not become illiterate after they graduate from school, and if they get rusty at riding a bicycle, the skill can be acquired with relatively little practice. Furthermore, part of what a person might learn in therapy is to expect downturns in mood and to interpret them as a normal part of their life, rather than as an indication of an underlying disorder. This understanding, along with the skills that the person has learned for coping with negative moods and situations, can help to prevent a depressive relapse.
