A Hybrid Effectiveness-Implementation Trial of Group CBT in Urban Schools

Inclusion Criteria: 1. Supervisors: Any participating agency clinical supervisor with a Master's degree or higher in a mental health field. 2. Therapists: Any STS therapist with a Bachelor's degree or higher who provides services in one of the 18 participating schools. 3. Students: Any student enrolled in grades 4-8 in one of the participating schools, who had been referred to the STS program in their school and who meets study screening and diagnostic criteria. The screening criterion is a Total score \> 25 on Screen for Child Anxiety Related Disorders (SCARED) completed by a parent or school staff member. This student must also present a primary positive or intermediate diagnosis of Separation Anxiety Disorder (SAD\]) Generalized Anxiety Disorder (GAD), or Social Phobia (SP) on the Anxiety Disorders Interview Schedule (ADIS); completed by a parent during the eligibility evaluation. 4. If, at the conclusion of the eligibility evaluation, students do not meet diagnostic criteria (see above) to participate in the study, but parents and school staff continue to express concern about functional impairment, students will be permitted to participate in the intervention sessions (with parent permission). We also expect that there might be a very small number of eligible children whose parents may not give consent, and some of these parents and school personnel might want these children to benefit from the intervention. As such, we would like to offer these children the opportunity to participate along with the research subjects. This group of students will not be identified as "research subjects" and study data will not be collected from them. However, parents will be asked to sign a permission form for the video recording of the group sessions. This is the procedure we currently follow for our National Institute of Child Health and Human Development (NICHD) funded project, which has been approved by the Institutional Review Board (IRB) of The Children's Hospital of Philadelphia and School District of Philadelphia. Exclusion Criteria: 1. Supervisors or therapists not involved in STS. 2. Students with Special Education classification of "Intellectual Disability;" children whose primary diagnosis is not SAD, GAS or SP. 3. Students with a history of psychotic or autistic spectrum disorders according to school records. * Students meeting criteria in #2 \& #3 above will be excluded from participation because they would be unlikely to benefit from Global Cognitive Behavioral Therapy (GCBTS). Subjects that do not meet all of the enrollment criteria may not be enrolled. Any violations of these criteria must be reported in accordance with IRB Policies and Procedures.
