BIOLOGICAL BASIS AND ETHICAL/LEGAL CONSIDERATIONS OF PSYCHOTHERAPY Many studies have found that psychotherapy is as effective as psychopharmacology in terms of influencing changes in behaviors, symptoms of anxiety, and changes in mental state. Changes influenced by psychopharmacology can be explained by the biological basis of treatments. But how does psychotherapy achieve these changes? Does psychotherapy share common neuronal pathways with psychopharmacology? Psychotherapy is used with individuals as well as in groups or families. The idea of discussing confidential information with a patient in front of an audience is probably quite foreign to you. However, in group and family therapy, this is precisely what the psychiatric-mental health nurse practitioner does. In your role, learning how to provide this type of therapy within the limits of confidentiality is essential. For this Discussion, you will consider whether psychotherapy also has a biological basis and analyze the ways in which legal and ethical considerations differ in the individual, family, and group therapy settings.
