Assisted living is rapidly becoming one of the most common methods of caring for older adults with dementia in long-term care. Over half of assisted living residents have dementia and many exhibit affective and behavioral problems related to the condition; residents' care and quality of life may suffer as a result of these problems. Despite the seriousness of this condition, interventions to teach direct care staff how to care for these residents are limited. This study will develop a program for teaching assisted living staff how to deal with the issues of patients with dementia and reduce mood and behavioral problems among this population.
