Objective:The aim of this study was to evaluate the acceptability of one specific e-training (intervention) for prevention of unwanted sexual behaviour in Australia's residential aged care services using the Theoretical Framework of Acceptability.Background: Aged care staff are of fundamental importance in unwanted sexual behaviour incident management and prevention. The research team developed and implemented an evidence-informed intervention designed to increase awareness, promote collaborative practice, and improve prevention and management of such incidents in aged care. Current acceptability of training on this topic is yet to be studied despite it being recognised as a key factor for successful implementation and translation into practice. study design and methods: This is a qualitative, cross-sectional study employing semi-structured telephone interviews with actively working enrolled and registered aged care nurses who had completed the intervention. Acceptability of the intervention was measured with the Theoretical Framework of Acceptability. Of the 36 participants that signed the consent form, 18 completed interviews. One participant was excluded from analysis as they did not complete all modules of the intervention. results: Analysis revealed favourable evaluation in all seven domains of the Theoretical Framework of Acceptability, finding high acceptability of the intervention amongst all participants. The intervention aligned with participant's values and the content was perceived to fill a knowledge gap. This is showcased in participants unanimous belief that it would be helpful for all front-line aged care staff to receive the intervention frequently. Although participants showcased high acceptability of the intervention, participants recommended that sexuality content be included before detailing unwanted sexual behaviour, and that this content inclusion may increase awareness and understanding of unwanted sexual behaviour. aUthOrs MeGhaN t WriGht BScAdvGlblChal(Hons) 1 DaisY e sMith BA AppSc (Psych) 1 chelsea s BairD BMed(Sci), MBBS(Hons), FRACP 1
