Study summary

Anxiety is a common mental health problem for Canadian adolescents. Anxiety that is diagnosed as a disorder and serious enough to require treatment affects up to 10% of all adolescents by the age of 16. The median age of onset is 11 years, making these disorders some of the earliest to develop. Anxiety disorders can have serious negative effects on a young person's personal relationships, school performance, and family life. These disorders may not be discovered by adolescents, parents and health care providers. Even if anxiety disorders are discovered, adolescents may not get the right therapy. Anxious adolescents can become sick if their anxiety is not treated properly. The investigators will carry out research to test Breathe, an Internet-based treatment for adolescents with anxiety problems. Adolescents can use this treatment from home via the computer. Breathe will include information materials and personalized homework assignments to help anxious adolescents learn ways to manage anxiety. More information can be found and www.TheBreatheStudy.com

Read the detailed description

This study is a randomized controlled trial (RCT) with two groups, an Internet-delivered cognitive behavioural therapy (CBT) experimental group (Breathe) and a resource webpage (control group; considered treatment as usual for youth waiting for services). The investigators will evaluate several methodological processes and outcomes through the following objectives:

  1. To determine the effectiveness of a self-guided Internet-based CBT program with limited telephone and email support in reducing anxiety symptoms among adolescents with mild-to-moderate anxiety as compared to a usual self-help intervention, a resource-based webpage.
  2. To explore mediators and moderators of the Internet-based CBT program.
  3. To determine the effectiveness of a self-guided Internet-based CBT program in improving quality of life as compared to a usual self-help intervention.
  4. To determine adherence to a self-guided Internet-based CBT program.
  5. To determine the cost-effectiveness of the Internet-based CBT program.

What researchers measure

Primary outcomes

  1. Change in adolescent anxiety using the total Multidimensional Anxiety Scale for Children (MASC 2) score

    Time frame: baseline to 6 weeks post-baseline (post-intervention)

Secondary outcomes

  1. Change in adolescent anxiety using the total MASC 2 score

    Time frame: 6 weeks post-baseline (post-intervention) to 18 weeks post-baseline (3-month follow-up)

  2. Change in quality of life using the Youth Quality of Life Instrument - Short Form (YQOL-SF)

    Time frame: baseline to 6 weeks post-baseline (post-intervention), 6 weeks post-baseline (post-intervention) to 18 weeks post-baseline (3-month follow-up)

  3. User experience

    Developed by the investigators, this electronically administered, self-report instrument will assess participant satisfaction (e.g., ease of use, layout, convenience) perceived credibility and impact (e.g., helpfulness, knowledge gains, confidence in the program/website), and adherence and usage (e.g., barriers and facilitators to treatment) with an Internet-based program/webpage.

    Time frame: 6 weeks post-baseline (post-intervention)

  4. Intervention adherence

    Intervention adherence will be measured by documenting the number of sessions and homework tasks completed. The investigators will also record the number of tailored sessions completed by each participant (intervention condition) and site visits (control condition). These data will be collected through the intervention's software system.

    Time frame: 6 weeks post-baseline (post-intervention)

  5. health care utilization

    Developed by the investigators, this self-report instrument will assess whether participants have accessed health care resources (i.e., met with a psychologist/psychiatrist/family doctor/hospital etc.) and if so, how many times.

    Time frame: baseline, 18 weeks post-baseline

Other outcomes

  1. Recruitment rate

    Time frame: Through study conduct, an average of 1 year.

  2. Retention rate

    Time frame: Through study conduct, an average of 1 year.
