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

It is not an alternative to the BCW workflow but rather a tool to help users to implement it.

It currently takes the form of a website and Google Sheets workbook. The website has more functionality and is now the best way to use it.

When you access the tool, please carefully read the instructions!

On 8th July we released Version 1.8.1 of CACTIS. It is a significant upgrade on previous versions but is backwards-compatible with Version 1.7.2 in terms of saved projects. However, if you want to keep using Version 1.7.2 here is a link.
