Preparing care home staff to manage challenging behaviours among residents living with dementia: A mixed-methods evaluation.

We evaluated an intervention designed to manage challenging behaviours of people with dementia. Framework analysis of interviews ( n  = 21) showed the intervention modified practice and perceptions. The intervention ( n  = 58; power calculation proposed n  = 160 for medium effect) had no significant effect on attitudes to dementia for time ( p  = .42) or care home ( p  = .15). The Maslach burnout scores did not change significantly for person-centredness for time ( p  = .83) or care home ( p  = .29). Hope scores showed a significant effect post-intervention ( p  = .004), but this was not maintained. No significant main effect was found for care home ( p  = .36). Experiential learning enabled staff to experience benefits of person-centred care firsthand.
