San Rocco Study: Implementation of the Non-pharmacological Therapies for People With Dementia Living in Nursing Home

To estimate how much time (i.e., minutes per day) the professional caregivers take to carry out the non-pharmacological therapies for people with dementia.

To estimate the number of professional caregivers required to carry out the non-pharmacological therapies for people with dementia.

Change in professional caregivers' burnout, as measured by the Maslach Burnout Inventory (MBI), from baseline to first and second follow up. The investigators expect a significant difference in the experimental group compared with the control group. The Maslach Burnout Inventory is a self-administered questionnaire with scores ranging from zero to 132, with higher scores indicating more severe burnout symptoms.

Change in the professional caregivers' sense of competence, as measured by the Sense of Competence in Dementia Care Staff Scale (SCDS), from baseline to first and second follow up. The investigators expect a significant difference in the experimental group compared to the control group. The Sense of Competence in Dementia Care Staff Scale is a self-administered questionnaire with scores ranging from 17 to 68, with higher scores indicating higher self-perception of competence.

Change in the quality of life of people with dementia perceived from professional caregivers, as measured by the Quality of Life in Late-stage Dementia questionnaire (QUALID), from baseline to first and second follow up. The investigators expect a significant difference in the experimental group compared to the control group. The Quality of Life in Late-stage Dementia questionnaire is a self-administered questionnaire with scores ranging from 11 to 55, with higher scores indicating lower quality of life for people with dementia.

Change in the professional caregivers' perception of social capital and ethical climate, as measured by the self-administered questionnaire Social capital and ethical climate at the Workplace of a hospital scale (SEW), from baseline to first and second follow up. The investigators expect a significant difference in the experimental group compared to the control group. The Social capital and ethical climate at the Workplace of a hospital scale is a self-administered questionnaire and it consists of three sub-scales: the higher the mean score of two sub-scales (social capital in the workplace and ethical leadership), the greater the participants' perceived favourable characteristics, and the higher the mean score of one sub-scale (exclusive workplace climate), the greater the participants' perceived unfavourable work environment characteristics.

Change in the behavioral and psychological symptoms in dementia (BPSD), as measured by the Neuropsychiatric Inventory Nursing Home (NPI-NH), from baseline to first and second follow up. TThe investigators expect a significant difference in the experimental group compared to the control group.The Neuropsychiatric Inventory Nursing Home was validated for interviewing the professional caregivers on twelve behavioural areas, including depression. The frequency [from one (rarely, less than once a week) to four (very often, once, or more per day)] and the severity [from one (mild) to three (severe)] of each BPSD are reported. The domain scores (frequency × severity) are added into the total score, ranging from zero to 144, with higher scores indicating more severe symptoms.
