Though the impetus for psychoanalytic and group-analytic inpatient psychotherapy largely came from Britain, it was in Germany that this work was supported, developed and researched to a greater extent than elsewhere. Originally published in English for the first time in 1994, Paul Janssen describes the different models which had been tried and evaluated and explains his own integrative model in detail, illustrating it with vivid clinical vignettes. The author also shows that inpatient groups are particularly effective in the treatment of severe personality disorders, borderline conditions and psychosomatic illness. This book will still be valuable reading for psychiatrists, psychotherapists, nurses, social workers and anyone working in health care today.
