The CACTIS (COM-B Assessment Criteria To Intervention Strategy) tool aims to help behavioural researchers and practitioners to use the COM-B model and the Behaviour Change Wheel (BCW) to develop an intervention strategy.

It currently takes the form of a Google Sheets workbook, but we are working on a website that will provide more interactive support and get over the fact that some organisations block their employees from using Google assets.

When you access the tool, carefully read the instructions (accessed by the leftmost tab at the bottom). If you are unable to use Google Sheets then download the workbook as an Excel file. Unfortunately Excel doesn’t allow multiple selections so the BCT selection won’t work but you can at least see how the COM-B questions map on to the Behaviour Change Techniques by viewing the ‘BCT list’ tab.

Please note that this is all work in progress. If you get a chance do please click on the feedback link and give us any suggestions as to how to improve this tool.
