The dynamic nature of mental health practice today is reflected in this informative and stimulating resource. The first section overviews societal and cost issues related to mental health problems. The contributors then focus on the expanding base of knowledge in the mental health field, such as that arising from neuroscientific and social research, psychoeducation, self-help and advocacy groups. The third section examines populations with special needs, including homeless people whose numbers have risen in recent years - due in part to their expulsion from institutional care. Finally, the volume discusses the future of mental health policy and practice, which will be influenced by technology and shifts in funding to managed care.
