About this study

Official title: Development and Preliminary Evaluation of a New Internet-Delivered Cognitive Behavioral Intervention for Youths With Anxiety Disorders

The goal of this study is to develop a new internet-delivered cognitive behavioral therapy (ICBT) intervention for youths with anxiety disorders based on the best current knowledge about effective cognitive behavioral therapy for the target group, refine the intervention in collaboration with patient and public representatives, and conduct a preliminary evaluation of the treatment effects in an open clinical trial.

The primary objective of the study is:

Read more
  1. To evaluate the preliminary efficacy of a newly developed ICBT intervention for children and adolescents with anxiety disorders in reducing anxiety severity, as measured by the Pediatric Anxiety Rating Scale (PARS).

Secondary objectives of the study are:

  1. To examine the preliminary efficacy (PARS) of the ICBT intervention at 3 months post-treatment.
  2. To examine how youths with anxiety disorders, their caregivers, therapists, and healthcare leadership experience the ICBT intervention.
  3. To examine factors (e.g., age, type of anxiety disorder, presence of depressive symptoms, experiences of ICBT) that predict treatment outcome.
  4. To examine how the ICBT intervention can be improved (e.g., treatment content and technical delivery) for future use.

Participants will:

  • Undergo ICBT treatment for anxiety disorders during 12 weeks
  • Complete questionnaires at multiple time points throughout the study
  • Participate in follow-ups post-treatment and 3 months post-treatment
  • A selection of participants will also be invited to focus group interviews with the aim to generate ideas on how the intervention may be improved for future use

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Internet-Delivered Cognitive Behavioral TherapyBehavioural

    The intervention is a therapist-guided, internet-delivered cognitive behavioral therapy (ICBT) program primarily based on exposure therapy, involving the gradual confrontation of feared situations and/or stimuli. Treatment is accessed through a smartphone, tablet or laptop/desktop device. The 12-week intervention is available in two different versions depending on the participant's age: one for 8-12-year-olds and one for 13-17-year-olds. Each version consists of separate logins to 12 modules (chapters) for the child/adolescent and 12 modules for the caregivers. Both the child/adolescent and caregiver have individual contact with a trained therapist over the internet platform. The therapist provides feedback, responds to questions and sends reminders to complete the next module if required. Communication is carried out via text messages in the platform, via telephone (if deemed justified) and through a scheduled telephone or videoconference call approximately 4-5 weeks into treatment.

How can a doctor refer a patient or contact the research team?

Contact Per Andrén, PhD (+46 70-435 17 40, per.andren@med.lu.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pediatric Anxiety Rating Scale (PARS) (time frame: Baseline; post-treatment (window of 12 to 18 weeks post-enrollment); 3-months post-treatment (window of 23 to 31 weeks post-enrollment).). It is what the study was designed to measure, not a finding.
