Materials and tools

Downloadable materials to support social workers in practice

Sample chapters from the C-Change; Capacity to Change Assessment Manual are now available to download.

We hope that access to these chapters will provide an introduction to the C-Change approach to assessing parental capacity to change, and help you consider how it can assist you in your practice or research with children and families.

Please note that the available chapters are pre-publication samples and therefore do not contain the same graphics as the hard copy of the Manual. The sample chapters of the Manual are freely downloadable subject to following copyright conditions:

The chapters may be downloaded, viewed and printed for personal, non-commercial use or for internal non-commercial circulation within your organisation provided that:

· No trademark, copyright or other proprietary notices contained in or that appear on the material are removed and the University of Bristol is attributed as the copyright owner. For the avoidance of doubt, the Handbook may not be reproduced in whole or in part or exploited for commercial gain.

· No material may be altered in any way without the University’s written consent.

· All other rights are reserved.

Copies of the full C-Change manual are available through attendance at a C-Change training course, provided by our training partner Interface Enterprises. We strongly recommend investing in training to enable practitioners to fully explore the C-Change approach and gain advice and support in how to use it in practice.

For more information on the training options available please look at our training page and read the opinions of practitioners already trained in the C-Change approach, and commissioners, from the Interface website.

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.
