Table 2 A summary of the content of each co-production workshop and post-workshop activity completed by researchers

Introduction to the topic of sedentary behaviour and the intervention target behaviours for each user group

Defining the problem (step 1), identifying the target behaviour (step 2)

Findings from workstream one (health benefits of reducing sedentary behaviour) and workstream two (sedentary behaviour after stroke) incorporated into expert video and infographic

Introduction to co-production and opportunity to practise a co-production activity—methods for breaking up sedentary behaviour in workshops

Summarising methods and devising a plan for incorporating strategies to reduce and break up sedentary behaviour into subsequent workshops

Further specification of the target behaviours for each user group in terms of who, where, when, communication etc.

Specifying the target behaviour (step 3)

Summarising the target behaviour (based on BCW Table 3)

Utilisation of ‘personas’ to consider the barriers and facilitators for the three user groups (stroke survivors, caregivers, staff) achieving the target behaviour, via group activity

Identifying what needs to change (step 4)

‘Personas’ developed based on findings from workstream two—related barriers and facilitators to achieving target behaviour

Completing the behavioural diagnosis for each user group (based on BCW Table 4)

Development and appraisal of solutions to the barriers generated in workshop two, that align with the target behaviour for each user group, via group activity

Identify intervention functions (step 5), identify behaviour change techniques (step 7), identify modes of delivery (step 8)

Infographic illustrating components of effective sedentary behaviour interventions based on findings from workstream one

Coded solutions to intervention functions and delivery methods (based on BCW Table 8)

Developed a prototype intervention (specifying how each intervention strategy linked to TDF domain from behavioural diagnosis) based on coded solutions and delivery methods, including application of APEASE^a

Appraisal of the proposed intervention, based on the solutions generated in workshop 3, via group activity and individual validation activity

Identify intervention functions (step 5), identify behaviour change techniques (step 7), identify modes of delivery (step 8)

Calculated scores from validation activity and summarised data

Revised prototype intervention based on workshop data

Commenced BCT coding of the prototype intervention

Developed a selection of prototype materials

Review of prototype materials via group activity

Identify modes of delivery (step 8)

Summarised appraisal of prototype materials and revised prototype intervention in line with this BCT coding of prototype intervention operationalised the intervention—development of all materials
