This study uses functional magnetic resonance imaging (fMRI) to learn how the brain functions in adolescents receiving fluoxetine (Prozac) cognitive behavioral therapy (CBT) or interpersonal therapy (IPT) for anxiety or depression in children/adolescents.

All participants will receive interviews to assess how they are doing in general, including general mood, degree of nervousness and behavior. Each participant and one of his or her parents will be interviewed separately and together. Those electing the medication study will also receive a physical examination. Participants are asked to complete tasks involving problem-solving and memory that involve looking at pictures, remembering things, testing reaction times, and making simple choices.

Participants with anxiety or depression will first meet with a psychiatrist or psychologist for two weekly sessions of talk therapy. Those who remain anxious or depressed after these 2 weeks will have the 3 options based on their choice: 1) treatment with fluoxetine daily for 8 weeks 2) cognitive-behavioral therapy or interpersonal therapy (two kinds of talk therapy) once a week for 8 weeks 3) a random assignment (50% chance) to either placebo or fluoxetine for 8 weeks. During and after the 8 weeks of treatment, each participant will complete verbal and written symptom ratings. Blood samples will be drawn for laboratory tests before drug treatment and after it ends.

Those who have not improved by the end of the study will be offered other treatment for 1 to 3 months, and the clinicians will help with finding subsequent aftercare. Those who improve with treatment will continue therapy at NIH until an outside physician is able to assume responsibility for monitoring medication.
