By using motivation interviewing strategies such as validating their emotions (e.g. providing affirmations and encouragement) and using a summary of what they have told you, you show that you have been listening, you understand, and you care.
This makes patients more open to your treatment suggestions. By offering patients a range of treatment options they are more likely to engage in the treatment because they feel that they have chosen it themselves.
You might include psychology, medication, useful websites, self-help books, and exercise as possible options. You can also recommend the treatment that is likely to be the most effective.
