Information on the scale and scope of resident-to-resident abuse, including verbal, physical, material, psychological, and sexual abuse, is presented. Nursing homes (n = 249) from 10 States were used, with a total of 4,451 nurse aides in these facilities returning the questionnaire. Most nursing homes experienced verbal, physical, material, and psychological abuse, but sexual abuse was less common. The findings clearly show that both the scale and scope of resident-to-resident abuse is high in nursing homes. Resident-to-resident abuse is common enough to be considered an issue of concern impacting the quality of life and safety of many residents. Abstract published by arrangement with Taylor and Francis.
