Understanding the Implementation of CareCoach-A Blended eHealth Intervention for Carers of People Living with Dementia: A Qualitative Process Evaluation Using Normalisation Process Theory.

CareCoach seeks to enhance self-efficacy in family caregivers of people living with dementia and has been feasibility tested in a multicentre randomised controlled trial. The intervention offers two face-to-face sessions with a trained coach and access to an online platform with nine modules. This paper reports findings from an embedded qualitative process evaluation assessing implementation from the implementer's ('coach's') (n = 8) perspective using individual interviews and implementer group discussions. Qualitative data were transcribed verbatim, inductively coded and analysed using Normalisation Process Theory. Implementers demonstrated (1) 'Coherence' by seeking to understand how CareCoach compared to current practice, highlighting the importance of supporting coaches to differentiate and identify boundaries between their new 'coach role' and usual practice; (2) 'Cognitive Participation' by reviewing training and resources to understand their role own responsibilities and facilitate delivery of coaching sessions; group supervision and peer support were also emphasised; (3) 'Collective Action' through interactions with carers to deliver key behavioural aspects such as goal setting, problem solving, and providing feedback; and (4) 'Reflexive Monitoring' by appraising the intervention to gain useful insights that could facilitate refinement of CareCoach training and delivery. This study provides a theoretically informed understanding of the implementation of CareCoach for caregivers of people living with dementia and provides recommendations to enhance training for coaches, intervention delivery and carer engagement.
