The impact of a training intervention on nursing care for people with dementia in long-term care: A quasi-experimental study

Various dementia training interventions have been developed for nursing staff, but there is inconclusive evidence on their effectiveness and which elements are key to positive outcomes. The aim of this study was to evaluate how nurses assess the prevalence of challenging behavior of people with dementia, nursing staff members’ responses to challenging behavior, and nurses’ competence, before the training and three and 12 months after the training. The main content of the training intervention was advancing person-centered care and its development. Data were collected through a survey of nursing staff ( n = 127) at two Finnish nursing homes across three distinct time points. The TREND statement was used to enhance the quality and transparency of the research. The prevalence of challenging behavior in the experimental group significantly decreased one year after training, while no change was observed in the control group. No change in nursing staff members’ responses to challenging behavior was observed in either group over the study period. Nurses in the experimental group demonstrated significant improvements in self-assessed competence both three months and one year after the training intervention. Hence, regular nursing staff training can decrease the prevalence of challenging behavior among older people with dementia and enhance nurses’ competence in nursing. The support of supervisors plays a significant role in these changes.
