The C-Change manual refers to standard questionnaires and tools that can be used to support practitioners in understanding the barriers to and facilitators of change, and in assessing actual change if used on a before and after basis.

We strongly recommend that practitioners are trained in the C- Change approach and that the manual is not used in isolation. Our training courses support staff to gain skills and confidence, and to improve the quality and accuracy of assessments. The University of Bristol is working in partnership with Interface Enterprises Ltd who provide the training for the approach.

The developers of these tools have all kindly given their permission for their tools to be hosted on the C-Change website and to be downloaded for use by practitioners. We are grateful for their permission and ask that practitioners respect this by using the tools faithfully and in the way they were intended. The tools are not to be amended in any way, nor are they able to provide a diagnosis of any clinical condition. They are best used to provide an objective measure of change or to explore issues in an alternative manner and as a springboard for discussion.

Before selecting a tool to use please consider carefully which would be the most appropriate. Information on what to consider can be found in Chapter Four of the manual and the available training will explore the use of tools in detail.

If any issues arise when using the tools please either contact or access the suggested website listed next to the tool.
