Stepped Versus Stratified Care for Anxiety Disorders in Youth: A Pragmatic Non-Inferiority Randomized Controlled Trial

Обзор

The goal of this clinical trial is to compare stepped care to stratified care as overall healthcare models for children and adolescents aged 8-17 with anxiety disorders. It addresses one main question: • Is stepped care non-inferior to stratified care in supporting participants to achieve a treatment response? Researchers will compare two care models: * Stepped care, where all participants begin with 14 weeks of internet-delivered cognitive behavioral therapy (ICBT) and receive an additional 14 weeks of personalized in-person CBT if needed. * Stratified care, where participants are assigned to either 14 weeks of ICBT or 14 weeks of in-person CBT based on clinical complexity, and may also receive additional 14 weeks of in-person CBT if necessary. Participants will: * Be randomly assigned to one of the two care models. * Complete a wide range of assessments at baseline, during treatment, and at 4, 8, 12, and 24 months, with the 8-month point as the primary endpoint. * Receive either ICBT, in-person CBT, or both, depending on their care model and response to treatment. * Participate in ancillary studies involving DNA sampling, cognitive testing, and national registry linkages to help predict treatment response and long-term outcomes.

Вмешательства

• Поведенческое Internet-delivered cognitive-behavioral therapy
  Internet-delivered cognitive behavioral therapy (ICBT) is a 12-module intervention delivered over a maximum of 14 weeks. Two age-specific versions are available: \[1\] for children aged 8-12 years and \[2\] for adolescents aged 13-17 years. Both versions share the same core content, but the texts, illustrations, videos, and exercises are adapted to be developmentally appropriate. Each version focuses on exposure, along with psychoeducation, coping strategies, and relapse prevention. Caregivers h
• Поведенческое Personalized in-person cognitive-behavioral therapy
  Personalized in-person cognitive-behavioral therapy (CBT) follows a manual drawing on previously published protocols and meta-analyses on effective components of CBT for pediatric anxiety disorders and results from our pilot study. It consists of 12 weekly one-hour sessions delivered over a maximum of 14 weeks. It follows a disorder-specific CBT approach, with a strong emphasis on therapist-led exposure tailored to the patient's principal anxiety disorder. Participants receive workbooks containi

Критерии исключения

• Principal DSM-5-TR anxiety disorder of specific phobia concerning the domain of blood-injection-injury (due to the ICBT program not including relevant information on applied-tension techniques to avoid fainting during exposure exercises). Confirmed by a specific phobia of this sort being classified as the most functionally impairing anxiety disorder during the structured diagnostic interview (DIAMOND-KID).
• Ongoing psychological treatment for an anxiety disorder. Confirmed by the child and/or caregiver.
• Social/familial/educational difficulties in more immediate need of management than an anxiety disorder. Confirmed by the assessor through information from the child and/or caregiver and/or other available sources.
