- Brief Summary
The purpose of this trial is to evaluate the feasibility, acceptability, and safety of two care pathways (including internet-delivered cognitive behavioral therapy \[CBT\] and/or in-person CBT) for children and adolescents with anxiety disorders.
- Detailed Description
Introduction: Anxiety disorders are a major contributor to disability in children and adolescents. Cognitive behavioral therapy (CBT), delivered both in-person and by the internet (ICBT), is efficacious, but how to best organize the care pathway to increase access and benefit is unclear.
Methods: With the aim to conduct a fully powered randomized controlled trial, the present study is a randomized controlled, single-blind, pilot study where 50 youth with anxiety disorders and their caregivers will be randomized (1:1) to stepped care or stratified care. Stepped and stratified care are two competing service delivery models which include evidence-based interventions but differ regarding the timing and staging of interventions.
In the stepped care arm, all participants will begin with 12 modules of ICBT delivered over 12 weeks. Participants with an insufficient response will then be offered 12-weeks of personalized in-person CBT. In the stratified care arm, the investigators aim to offer about half of the participants ICBT and the other half in-person CBT, with this selection being based on a risk score algorithm that integrates known predictors of non-response to treatment.
Mirroring the structure in stepped care, all non-responders in stratified care (both those who started with ICBT and in-person CBT) will be offered an additional 12-week course of in-person CBT. The ICBT and in-person CBT interventions will be identical in treatment length, but will differ in the delivery of treatment, utilizing the possibility of increased personalization and therapist-involvement in in-person CBT.
The objectives of the pilot study are to examine feasibility, acceptability, and safety of study procedures, precision of the risk score algorithm, and statistical properties of outcome measures. The feasibility, acceptability, and safety objectives are operationalized in detail in the full study protocol published at the Open Science Framework (OSF; see link in the References-section at the bottom of this record).
Data will be collected at baseline, post-allocation (week 1), weekly during treatment course A (week 2-13), after treatment course A (POST-1; time window for data collection between week 14-17), weekly during treatment course B (if applicable, week 18-29), and after treatment course B (POST-2; time window for data collection between week 30-33). POST-2 is the primary endpoint of the study.

Group Intervention Description Stepped care Internet-delivered cognitive behavioral therapy (ICBT) Participants will receive up to two courses of treatment. All participants in stepped care will receive internet-delivered cognitive behavioral therapy (ICBT) in the first course (A). Participants with an insufficient treatment response will then be offered in-person cognitive behavioral therapy (CBT) in the second course (B). Even if participants are offered treatment in course B, participants are free to decline this offer, and will instead only be invited to the remaining outcome assessments. Stepped care In-person cognitive behavioral therapy (CBT) Participants will receive up to two courses of treatment. All participants in stepped care will receive internet-delivered cognitive behavioral therapy (ICBT) in the first course (A). Participants with an insufficient treatment response will then be offered in-person cognitive behavioral therapy (CBT) in the second course (B). Even if participants are offered treatment in course B, participants are free to decline this offer, and will instead only be invited to the remaining outcome assessments. Stratified care Internet-delivered cognitive behavioral therapy (ICBT) Participants will receive up to two courses of treatment. In stratified care, in treatment course A, the investigators aim to offer around half of the participants ICBT and the other half in-person CBT (based on their risk of non-response). All participants in stratified care who do not sufficiently respond to treatment in course A will be offered personalized in-person CBT in course B. Even if participants are offered treatment in course B, participants are free to decline this offer, and will instead only be invited to the remaining outcome assessments. Stratified care In-person cognitive behavioral therapy (CBT) Participants will receive up to two courses of treatment. In stratified care, in treatment course A, the investigators aim to offer around half of the participants ICBT and the other half in-person CBT (based on their risk of non-response). All participants in stratified care who do not sufficiently respond to treatment in course A will be offered personalized in-person CBT in course B. Even if participants are offered treatment in course B, participants are free to decline this offer, and will instead only be invited to the remaining outcome assessments.
