Introduction: Stroke survivors spend long periods of time engaging in sedentary behaviour (SB) even when their functional recovery is good. In the RECREATE programme, an intervention aimed at reducing SB ('Get Set Go') will be implemented and evaluated in a pragmatic external pilot cluster randomised controlled trial with embedded process and economic evaluations. We report the protocol for the process evaluation which will address the following objectives: (1) describe and clarify causal assumptions about the intervention, and its mechanisms of impact; (2) assess implementation fidelity; (3) explore views, perceptions and acceptability of the intervention to staff, stroke survivors and their carers; (4) establish the contextual factors that influence implementation, intervention mechanisms and outcomes.
Methods and analysis: This pilot trial will be conducted in 15 UK-based National Health Service stroke services. This process evaluation study, underpinned by the Medical Research Council guidance, will be undertaken in six of the randomised services (four intervention, two control). Data collection includes the following: observations of staff training sessions, non-participant observations in inpatient and community settings, semi-structured interviews with staff, patients and carers, and documentary analysis of key intervention components. Additional quantitative implementation data will be collected in all sites. Training observations and documentary analysis data will be summarised, with other observational and interview data analysed using thematic analysis. Relevant theories will be used to interpret the findings, including the theoretical domains framework, normalisation process theory and the theoretical framework of acceptability. Anticipated outputs include the following: recommendations for intervention refinements (both content and implementation); a revised implementation plan and a refined logic model.
Ethics and dissemination: The study was approved by Yorkshire & The Humber - Bradford Leeds Research Ethics Committee (REC reference: 19/YH/0403). Findings will be disseminated via peer review publications, and national and international conference presentations.
Trial registration number: ISRCTN82280581.
