In establishing an agreement between you as the psychologist or therapist and the patient soon to undergo psychotherapy, one of the things you both should agree upon is not to disclose any information obtained during the sessions. Ensuring confidentiality is one of the main things that should be made clear before beginning the therapy sessions and should be written down on your counselling form.
Why is it important to keep mum over what has happened during the psychotherapy session? As psychologists, you are aware that people are more comfortable in talking about sensitive and revealing information with people of your profession. They consider these therapies as their safest outlet where they can divulge everything without the fear of having their secrets revealed. Your patients trust you to safeguard their deepest secrets, something you can guarantee through your counselling forms.
The British Association for Counselling & Psychotherapy believes in the importance of confidentiality in psychotherapy and lists Being Trustworthy in their ethical principles of counselling and psychotherapy. You are to inform their patients beforehand if they are to record the session, either through audio or video recording devices. Moreover, it is your duty not to disclose information about your patients in your academic writings, lectures, or other public media unless you have obtained legal authorisation to do so or you are to take steps to disguise the individual.
