Most of the treatments in this book are described as self-aid, but they can also be used to treat others.
It is important to remember that although you are trying to help someone it is ultimately up to them, or an advocate on their behalf, if and how you can treat them. If they refuse or object to your help you should respect their request.
It is also important to give patients the full range of options and to let them choose which course of action to take. You can give them your recommendation, but it is up to them to make the final choice.
If a patient is incompetent/unable to give consent and there is no advocate, whether to help them is a decision you will have to make.
