Communication is fundamental for dementia care across long-term services and support (LTSS) settings. Education increasing nursing home (NH) staff awareness of person-centered communication has reduced staff elderspeak communication and reduced resistiveness to care of residents with dementia. The current study tested the Changing Talk Online (CHATO) education with adult day services (ADS) staff to identify strategies for adaptation for other LTSS settings. Three dementia-specific ADS sites participated in the CHATO education program. Participants completed knowledge assessment, communication ratings, and confidence ratings on providing care pre- and post-CHATO; a program evaluation; and rated their intention to use skills in practice. Findings were compared to an earlier study of CHATO in NHs. Focus groups evaluated feasibility, applicability, and directions for tailoring. Mean scores on the Changing Talk Scale knowledge test increased by 15 percentage points (p < 0.001). Confidence in providing dementia care scores also increased (p = 0.037). The mean Modified Diffusion of Innovation scale score was 2.2, similar to that in NHs, indicating intent to use skills; and program evaluation was positive. Focus group participants reported CHATO was valuable and recommended incorporating scenarios specific to ADS care. [Research in Gerontological Nursing, 16(2), 85-94.].
