Communication services for long-term care residents with Alzheimer's disease are restricted due to treatment models and assumptions, as well as reimbursement. As the severity of dementia increases, fewer communication management approaches are available. However, demands for functional interventions persist This article reviews Validation Therapy, a Rogerian intervention approach for patients in the severe stage of Alzheimer's disease. Validation Therapy addresses the patient's need to maintain contact with the environment by confirming the patient's internal emotional state, rather than coercing an external environmental orientation. Techniques and efficacy studies are reviewed; case examples of the application of Validation Therapy are provided.
