This review included six studies of various intervention programmes. Three uncontrolled studies looked at the effects of a caregiver communication training programme called FOCUSED (n=125). One case study (n=2) assessed the effect of an individualised programme on a male with Alzheimer's Disease and his carer (spouse). A non-randomised controlled study (n=66 family carers, 66 Alzheimer's Disease care home residents) compared a Family Visit Education Program with no intervention. Finally, a randomised controlled study assessed the effect of a Nursing Assistant Communication Skills Program on nursing home residents' well being, nursing assistants' knowledge and staff turnover (carers n = 88, residents n = 105).
Educating caregivers in communication strategies appeared to have the following effects: more successful conversational exchanges; reduced or increased caregiver burden (evidence mixed); improved quality of life for people with Alzheimer's Disease; maintenance of language abilities people with Alzheimer's Disease; and increased knowledge/understanding of communication in Alzheimer's Disease.
