The study delivers intervention in 12 languages in the form of workbook, videos and short messaging using cellular device and internet as a tool. Objectives of process evaluation are to assess whether trial was implemented as planned (fidelity and dose); whether, how and why the intervention is effective by looking at the stakeholders’ experiences (effectiveness); to assess reach of intervention in population (reach); how intervention fits into treatment plan to cause behavioural change when adopted (adoption); usefulness for target population and bring behaviour change (maintenance).MethodsSPRINT India process evaluation is a prospective, multicentre study conducted with mixed-methods approach.

Centres will be stratified primarily for representing the 11 regional language in which the intervention is delivered. Qualitative data will comprise of interviews of patients, care givers and health professionals at these centres using semi structured interview guide.

Analysis will be done using triangulation methodology. It will incorporate use of both quantitative and qualitative data, data collection techniques, data sources, evaluation models, stakeholders and researchers.ConclusionsProcess evaluation will identify efficacious factors in intervention package and consolidate use of secondary stroke semi-interactive stroke prevention package into practice and policy to prevent recurrent stroke.
