Theory and Treatment of Depression [PDF ebook] 
Towards a Dynamic Interactionism Model

Recent research indicates that depression, once believed to be relatively benign, is highly recurrent and does not respond well to treatment. The goal of this book is to facilitate the development of more encompassing theories and more effective treatments for this disabling disorder by fostering dialogue and enhancing the integration of work across the boundaries of separate fields.
