This book looks at the collaborative health care model for the delivery of mental health care in a primary care setting. This has become the ideal model for the treatment of comorbid medical and psychiatric or psychological disorders. There is also an increased awareness that pharmacological intervention, the most frequently delivered intervention for psychological disorders, is often of limited effectiveness without concurrent specific psychological intervention. Further, Kessler shows that most psychological care these days is delivered through primary carepatients prefer to receive psychological care in that setting, and if they are referred elsewhere, it becomes less likely that they will follow through. In all, moving mental health care into primary care has been shown to improve both the medical and psychological outcomes, and it requires careful attention to implementation issues, besides evidence-based clinical interventions. The book will include 25-30 case studies, co-written by clinical psychologists and primary care physicians.
