The facilitators and barriers to improving functional activity and wellbeing in people with dementia: A qualitative study from the Process Evaluation of Promoting Activity, Independence and Stability in Early Dementia

Background The PRomoting Activity, Independence and Stability in Early Dementia (PrAISED) study delivered an exercise and functional activity programme to participants living with dementia. A Randomised Controlled Trial (RCT) showed no measurable benefits in activities of daily living, physical activity or quality of life. Objective To explore participants’ responses to PrAISED and explain the mechanisms behind a complex intervention that did not lead to expected health gains. Methods A process evaluation using qualitative methods, comprising interviews and researcher notes Setting Data were collected in participants’ homes or remotely by telephone or videoconferencing. Sample Eighty-eight interviews were conducted with 44 participants living with dementia (n = 32 intervention group; n = 12 control group) and 39 caregivers. Sixty-nine interviews were conducted with 26 therapists. Results Participants valued the intervention as proactively addressing health issues that were of concern to them, and as sources of social contact, interaction, information, and advice. Facilitators to achieving positive outcomes included perceiving progress toward desired goals, positive expectations, therapists’ skills and rapport with participants, and caregiver support. Barriers included: cognitive impairment, which prevented independent engagement and carryover between sessions; chronic physical health problems and intercurrent acute illness and injury; ‘tapering’ (progressively infrequent supervision intended to help develop habits and independent activity); and the COVID-19 pandemic. Conclusions Interventions aiming to maintain activity, independence and stability may not be appropriate in the context of dementia even in the mild stages of the condition. Various factors affected outcomes including caregiver support, rapport with therapists, availability of supervision, motivational factors, and the limitations of remote delivery. The effects of cognitive impairment, multimorbidity and frailty overwhelmed any positive impact of the intervention. Maintenance of functional ability is valued, but in the face of inevitable progression of disease, other less tangible outcomes become important, challenging how we frame ‘health gain’ and trial outcomes. ### Competing Interest Statement The authors have declared no competing interest. ### Clinical Trial The ISRCTN Registration Number for PrAISED is 15320670 ### Clinical Protocols ### Funding Statement This work was funded by the National Institute for Health Research (NIHR) under its Programme Grants for Applied Research Programme (Reference Number RP-PG-0614- 20007).
