The treatment of depression remains a daunting, always perplexing challenge. Its ubiquitous presence makes depression a major public health problem. The presence of newer, better, safer, less troublesome medications provides a sometimes seductive view that depression is easy to treat. Nothing could be farther from an accurate picture of this tenacious group of illnesses. These costly medications are effective, but they are not prescribed in a well-defined manner. The diagnosis is often generic and general, the plan of treatment vague, the enthusiasm for treatment brief, and the relapse rapid. It is the area of relapse prevention that is the focus of this book.
