Module 3-1 – Developing the Intervention (14-Minute Video)

• Discover how to design pragmatic healthcare interventions that work in real-world settings. This module examines the distinction between defining core and adaptable elements, mapping workflows, creating a minimum viable intervention package, and developing training materials for frontline staff. You’ll also learn how to build fidelity checks and assess acceptability, ensuring your intervention is both consistent and scalable.

• A non-comprehensive checklist for developing a pragmatic trial intervention.

Theory-Informed Questionnaire to Assess the Acceptability Questionnaire (PDF) 

• Generic form of TFA acceptability questionnaire.

TIDieR Checklist and Guide (PDF) 

• This paper highlights a common problem in medical research: many studies fail to clearly describe their interventions, leaving doctors, patients, and other researchers unable to replicate or adapt them in real-world practice. Without sufficient details, valuable findings risk being wasted. 

• The TIDieR checklist is a 12-item guide that encourages trialists to report essential features of an intervention, such as its purpose, materials, delivery method, who provides it, where and when it occurs, and how well it is carried out. By improving clarity and completeness, TIDieR strengthens replication, transparency, and the usefulness of health research.

Development of a theory-informed questionnaire to assess the acceptability of healthcare interventions (PDF) 

• The theoretical framework of acceptability (TFA) was developed in response to recommendations that acceptability should be assessed in the design, evaluation and implementation phases of healthcare interventions. The TFA consists of seven component constructs (afective attitude, burden, ethicality, intervention coherence, oppor￾tunity costs, perceived efectiveness, and self-efcacy) that can help to identify characteristics of interventions that may be improved. The aim of this study was to develop a generic TFA questionnaire that can be adapted to assess acceptability of any healthcare intervention.

Acceptability of healthcare interventions: an overview of reviews and development of a theoretical framework (PDF) 

• The purpose of this study was to develop a multi-construct theoretical framework of acceptability of healthcare interventions that can be applied to assess prospective (i.e., anticipated) and retrospective (i.e., experienced) acceptability from the perspective of intervention deliverers and recipients.
