This paper will be an analysis of the psychological disorder of major depression. First, the classification of this disorder using the DSM-IV-TR will be reviewed. The areas of etiology, differential diagnosis, and treatment will then be considered. Following, a theory-specific approach to the disease including theoretical framework, diagnosis and treatment, and outcomes of using this approach, will be examined. Finally a personal reflection on the subject of major depression, and lessons learned from this project, will be discussed
