When it comes to treating depression, research shows there is no single type of therapy that is better than another. Talk therapy and antidepressant medication can be effective alone or combined -- medication can help patients feel better sooner while giving them the motivation to work out their issues. What’s most important is finding a therapist that you feel comfortable with -- someone you trust and can open up to. A specific kind of talk therapy, interpersonal psychotherapy (IPT), focuses on your current relationships and is based on the idea that depression may be triggered by poor relationships and unhealthy communication skills, explains Jeremy Pettit, Ph.D., associate professor of psychology and co-author of the book, The Interpersonal Solution to Depression: A Workbook for Changing How You Feel by Changing How You Relate. According to Pettit, a typical course of treatment is 10 to 20 weeks, with weekly therapy sessions. In addition to therapy and/or medication, exercise can also improve your mood. In a 16-week study, James Blumenthal, Ph.D., professor of psychology and neuroscience at Duke University Medical Center, found that 30 minutes of exercise three days a week was as effective as antidepressants at treating mild to moderate depression.
