Before and after a video feedback intervention in nursing homes: care staff’s perceived competence and strain, and well-being and distress behavior of people living with dementia

Objectives Investigate the differences in care staff's perceived competence and strain, and well-being and distress behavior of people with dementia before and after a video feedback intervention.Methods In this pre-post observational study, data were collected online before (T0) and after (T1) in 27 cases. Care staff outcome measures were Sense of Competence in Dementia care Scale (SCIDS), quality of communication and care relationship, caregiver distress scale of the Neuropsychiatric Inventory (NPI-NH/NPI-Q) and Strain in Dementia Care Scale. For people with dementia, outcome measures were NPI-NH, Cohen-Mansfield Agitation Inventory, Quality of Life In Late-Stage Dementia Scale (QUALID), and Revised Index for Social Engagement.Results Linear Mixed Model analyses showed significant increases over time among care staff (n = 152 at T0, n = 73 at T1) for SCIDS, quality of communication and care relationship, and significant decreases for NPI-NH/NPI-Q caregiver distress. A significant increase was found in quality of life of people with dementia (QUALID). Effect sizes indicate small to moderate effects, the effect size for QUALID was largest at 0.71.Conclusion Although our findings indicate that VIO may contribute positively to perceived competence of care staff and quality of life of people with dementia, future research must confirm our findings and investigate how outcome variables behave longitudinally at team level.
