PROJECT ABSTRACT In family caregiving situations, those with Alzheimer’s disease and related dementia (ADRD) are more likely to experience elder abuse and neglect (EAN) than older adults living alone or not requiring assistance with care. Elder abuse and neglect (EAN) is defined as acts committed by a person in a trusted relationship that cause actual or increased risk of harm to an older adults’ health and wellbeing. EAN consists of different subtypes such as physical and psychological abuse and neglect. About half of family caregivers for persons with dementia self- report doing at least one of these three EAN subtypes. This proposal evaluates an evidence-based tele-coaching intervention, Care-Resistant Behavior Internet Training (CuRB-IT) to enhance coping skills of family caregivers and reduce elder abuse and neglect (EAN). CRB includes actions taken by a person with ADRD to resist or refuse assistance with care, such as refusing to open their mouth for oral care or using physical aggression. Our tele-coaching intervention (CuRB-IT), which increases problem-solving coping skills by teaching practical strategies to manage CRBs, effectively reduces CRB-related caregiver distress. We will test the effectiveness of CuRB-IT in a delayed-intervention randomized clinical trial, within a multi-time series approach. Caregivers in immediate- and delayed-intervention groups (N=266) will complete 4 waves of instrument completion and daily diary surveys describing the frequency of CRB and EAN over a 21-day period at baseline, 3 months, 6 months, and 9 months. Delayed-intervention caregivers will receive weekly texts to reduce inflated intervention effects inherent in many wait-list control designs.22 After the 3-month follow-up, the delayed-intervention group will then receive the CuRB-IT intervention. This design allows us to maximize power to examine efficacy (between-group), mechanism-of-action, and intervention delay (within-group). Thus, we propose the following Specific Aims: 1) Test the efficacy of an online care-resistant behavior coaching intervention in reducing frequency of EAN (a) among the experimental (immediate-intervention group) as compared to the control (delayed-intervention group) (between groups) and (b) within-person from pre- to post- intervention.; 2) Test hypothesized mechanism of action through multi-level structural equation modeling to assess the relationships between CRB-stress appraisal, use of CuRB-IT problem-focused coping strategies and EAN; and 3) Examine intervention decay at 3- and 6-months post intervention to determine performance of intervention and inform scheduling of booster sessions. We will also assess the efficacy of the CuRB-IT intervention in preventing onset of EAN use by family caregivers as an exploratory aim. This proposal directly addresses high-priority research gaps identified by the NIH Office of Disease Prevention and US Preventative Task Force. Next steps in this research program will focus on trans...
