Irvin D. Yalom Quote
To the best of my knowledge, every acute inpatient ward offers some inpatient group therapy experience. Indeed, the evidence supporting the efficacy of group therapy, and the prevailing sentiment of the mental health profession, are sufficiently strong that it would be difficult to defend the adequacy of the inpatient unit that attempted to operate without a small group program.
