Person centred values:
Think of a complex or sensitive situation that could occur in your setting eg an individual wants to do something risky but their relative is against it and this is causing distress and frustration in both parties. Using the above how would you deal with it?
You need to demonstrate ie be seen doing it. You need a direct observation eg of you explaining something to an individual and encouraging them to become involved in decisions and actions.
You could do this, for example, by reminding a colleague that the individual has a right to choose where he wants to sit when she tells him to sit by the window.
Hope that helps
