A clinical psychologist has developed a new talk therapy treatment for depression. She has enlisted 20 volunteers from the community who are clinically depressed to take part in her new study. Half (10) of her participants will receive the antidepressant drug fluoxetine (Prozac) and the other half will receive no antidepressant drug. Additionally, for the group who receive the antidepressant drug, five participants will receive the new talk therapy treatment (new therapy) and five participants will receive traditional behavioral/cognitive talk therapy (behav/cog). For the other 10 participants who receive no antidepressant drug, five participants will receive the new talk therapy treatment (new therapy) and five participants will receive traditional behavioral/cognitive talk therapy (behav/cog).
