Brief summary: The purpose of this study is to see if it is safe and effective to use fluoxetine to treat children and adolescents with Generalized Anxiety Disorder (GAD).

Anxiety disorders are one of the most common psychiatric disorders in children and adolescents, and can cause disturbances in the child's school, social, and family lives. Having an anxiety disorder puts a child at risk for depression and drug abuse, and appears to continue into adulthood. There is very little information on anxiety medications for children.

Children will be assigned randomly (like tossing a coin) to receive either fluoxetine or an inactive placebo for 12 weeks. Each child will be monitored for symptoms and side effects throughout the study. He/she will have blood tests at Weeks 4, 8, and 12 to measure drug levels in the blood. The study will last for 12 weeks.

A child is eligible for this study if he/she:

Is 8 to 17 years old and has anxiety disorder.

A child will not be eligible for this study if he/she:

Has current major depression, panic disorder, or obsessive-compulsive disorder, or abuses alcohol or drugs.

Detailed description: To evaluate the safety and efficacy of fluoxetine as a treatment for children and adolescents with Generalized Anxiety Disorder (GAD).

Anxiety disorders are among the most common childhood and adolescent psychiatric disorders and are often associated with academic, social, and family morbidity. These disorders frequently increase the risk for developing other psychiatric disorders (e.g., depression, substance abuse), aggregate in families, and appear to continue into adulthood. Except for Obsessive-Compulsive Disorder, there are very few pharmacological treatment studies for childhood anxiety disorders. Given the sparsity and methodological problems of previous anxiety pharmacological studies, it is clear that further investigation of the use of pharmacological treatment of children and adolescents with these disorders is needed.

Patients are randomized to receive either fixed-dose fluoxetine or placebo for 12 weeks. Patients are assessed for psychiatric symptomatology, functional status, and side effects. In addition, to assess attainment of steady state and compliance with treatment, plasma levels of fluoxetine and norfluoxetine are measured at 4, 8, and 12 weeks. To standardize the treatment protocol and to assure that both groups (fluoxetine and placebo) receive equivalent nonpharmacological treatment, a manual is used. Potential predictors of clinical response (such as age, sex, duration and severity of anxiety, school absenteeism, sub-syndromal depressive symptoms, family history of anxiety or mood disorders) are explored.
