Study population: The study population consists children and adolescents ages 8 to 20 who are receiving medication treatment for a mood disorder, anxiety disorder, or obsessive compulsive disorder.

Brief summary: The purpose of this study is to examine the feasibility, acceptability, and utility of pharmacogenomic (PGX) testing (specifically for the cytochrome P450 2D6 and 2C19 genes) prior to initiating treatment with an antidepressant (AD) among children and adolescents in the University of Florida Child Psychiatry clinics.

Detailed description: This project will assess the feasibility of implementing pharmacogenomic testing (PGX) for specific genes involved in the metabolism of antidepressants (CYP2D6 and CYP2C19) into the child psychiatry clinic at UF.

Although not widely implemented to date, naturalistic studies in adult psychiatry populations have shown that PGX testing can improve patient outcomes, increase medication adherence, and reduce costs. However, there have been no studies of psychiatry-focused PGX testing in children. One in every four children and adolescents suffers from a mental illness (more than half have a mood or anxiety disorder) that is severe enough to impact their functioning at school, at home, or in other important areas. Although psychotherapy remains the first line treatment for children with mild or uncomplicated symptoms, the use of psychotropic medications in children has increased steadily over the last decade. These medications are effective for many children, but carry a substantial risk of side effects, including gastrointestinal, cognitive, systemic, and psychiatric (including treatment emergent suicidal ideation). For most treatment responders, improvement is typically seen four to eight weeks after the target dose has been achieved (twelve weeks for obsessive compulsive disorder). Thus, identifying the best medication options prior to treatment initiation could decrease the likelihood of side effects severe enough to require medication discontinuation or changes, and minimize the time to response. In this study, 50 children and adolescents with major depression, anxiety, or obsessive compulsive disorders who are beginning treatment with a new antidepressant will be recruited and PGX testing will be conducted. Twenty five children will be randomized to receive PGX testing prior to starting/changing medications and 25 to receive treatment as usual (these children will receive their PGX results at the end of 12 weeks). Members of the UF Health Personalized Medicine Program will provide education to the prescribing clinicians about PGX testing and will create patient-specific consultations regarding the PGX results.

Assess clinicians' and parents' willingness to use PGX testing in making treatment decisions, as well as their knowledge and beliefs about PGX testing (pre-and post-study). Also assess, as pilot data for a larger randomized controlled trial, differences in side effect profiles, treatment adherence, and symptom improvements between the PGX cases and controls.
