Single-Session Therapy by Walk-in or Appointment is based on the idea that one session is often all a client will need and choose to attend. The option of a single-session responds to the growing need for greater accessibility and responsiveness of mental-health services.　 With considerable data supporting both the demand for and the effectiveness of walk-in and by-appointment single sessions, the field is expanding rapidly. This book includes many clinical examples and cultural nuances, as well as discussions of recent research, training and supervision, and implementation and administrative arrangements. This is an essential title for clinicians, program developers, and policy makers interested in providing the effective, client-responsive, economic option of one-at-a-time single-session therapy on a walk-in or by-appointment basis.
