The purpose of this study is to determine whether there is a change in levels of cortisol, a key stress hormone, during the course of a psychotherapy session. The two forms of psychotherapy compared are Cognitive Behavioral Therapy (CBT) and Emotional Freedom Techniques (EFT). A no treatment control group provides a baseline measure. The change in cortisol level is compared between the start and end of a one hour session.
