3.1. Phase 1: Development of the content of the STOW‐V Checklist

A process for developing and using structured observations for the study of health behaviour described by Bentley and colleagues ¹⁵ informed the development of the STOW‐V Checklist. This involved generating a list of potential Key Behaviours through review of the literature, discussion with key stakeholders, refining selected behaviours into a structured observation format, defining the Key Behaviours and development of item ratings. ¹⁵ Principles for formatting of clear and effective medical checklists were used. ¹⁶ The Checklist was developed in the English language.
