Study summary

The study aims to evaluate the effectiveness of a cognitive behaviour therapy program (FRIENDS) for anxiety disorders in children aged 8-15 years who have been referred to child and adolescent mental health clinics in Western Norway.

Read the detailed description

Cognitive behaviour therapy (CBT) has been shown to be an efficacious treatment for anxiety disorders in youths when delivered in university settings. However, there is a lack of studies evaluating the effectiveness of CBT in regular clinical settings.

The current study will compare a CBT program developed for anxiety in youths (the FRIENDS program by Paula Barrett, Australia), with a wait-list control condition. Group and individual treatment will also be compared in the study. Groups will be divided by age, with younger including 8-12-year-olds, and older 12-15-year-olds. Parents are also involved at the end of all therapy sessions, as well as in separate parent sessions. Assessment and treatment is delivered by clinicians working in seven outpatient clinics in Western Norway.

There will be 10 therapy sessions, with booster sessions 4 and 12 weeks later. Effectiveness will be evaluated post-treatment, and at 1 and 5 years follow-up. The study will have a randomized design. Children randomized to the wait-list condition will be offered treatment if they still meet inclusion criteria after the waiting period.

  • Meeting criteria for separation anxiety, social anxiety or generalized anxiety disorder based on the ADIS interview schedule

Exclusion criteria

Exclusion Criteria:

  • Pervasive developmental disorders, Selective mutism, Mental retardation

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 8, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
