A new ray of hope has emerged in the fight against depression, particularly among young people. Researchers have found that a cognitive behavioral therapy (CBT) app can effectively prevent the increase of depressive symptoms in at-risk individuals. This innovative approach, rigorously tested across multiple countries, could represent a cost-effective public mental health measure, providing accessible support to those who need it most.
The Growing Concern of Depression in Young People
Globally, there’s increasing concern about the rising rates of anxiety and depression among young people. The need for effective and scalable solutions to address this issue is more pressing than ever. Digital tools, especially mobile apps, have been proposed as a potential part of the solution, offering a convenient and readily available means of support.
While there’s growing evidence that mental health apps can be effective in treating anxiety and depression, a recent project led by the University of Exeter marks a significant step forward. It’s the first project to rigorously test a mental health app on a large scale across four countries, providing robust data on its effectiveness in preventing depression.
The ECoWeB-PREVENT and ECoWeB-PROMOTE Trials
The findings come from two linked papers published in Lancet Digital Health, reporting the results of the ECoWeB-PREVENT and ECoWeB-PROMOTE trials. These trials, conducted over four years and funded by Horizon 2020, involved 13 different partners and examined the effects of mobile apps in preventing depression and promoting mental well-being in young people aged 16 to 22.
How the Trials Were Conducted
The study involved approximately 3,700 participants from the UK, Germany, Belgium, and Spain. Participants were divided based on their emotional competence levels, distinguishing between those at higher risk of depression and those without such risk. Each group was then randomly assigned to one of three apps:
- A self-monitoring app for tracking emotions.
- A self-help app focused on emotional competence skills.
- A self-help app based on CBT principles.
The participants were followed up at three and twelve months to assess changes in their well-being and depression symptoms.
Key Findings
The trials revealed that the CBT app effectively prevented an increase in depression among the high-risk group, relative to self-monitoring. However, there was no significant difference between any of the interventions for the lower-risk group.
Professor Ed Watkins from the University of Exeter, who led the project, explained that the findings suggest the self-help CBT app has a preventative effect on depression for young people with elevated risk and could have a public health benefit. He also noted that participants’ quality-of-life measures and reported work and social functioning were better.
Watkins further emphasized that prevention for depression works best when individuals at higher risk are identified and selected, rather than taking a universal approach. This identification could be done through an online self-screening process or professional referral.
What is Cognitive Behavioral Therapy (CBT)?
Cognitive behavioral therapy (CBT) is a type of psychotherapy that helps people identify and change negative thinking patterns and behaviors. It’s based on the idea that our thoughts, feelings, and behaviors are interconnected, and by changing one, we can influence the others. CBT is widely used to treat a variety of mental health conditions, including:
- Depression
- Anxiety disorders
- Obsessive-compulsive disorder (OCD)
- Post-traumatic stress disorder (PTSD)
- Eating disorders
Core Principles of CBT
CBT operates on several core principles:
- Identifying Negative Thoughts: CBT helps individuals become aware of their negative or unhelpful thought patterns.
- Challenging Thoughts: Once identified, these thoughts are challenged by examining the evidence for and against them.
- Changing Behaviors: CBT encourages individuals to change behaviors that contribute to their negative feelings.
- Developing Coping Strategies: Individuals learn new coping strategies to manage difficult situations and emotions.
CBT Techniques
Some common CBT techniques include:
- Cognitive Restructuring: Identifying and changing negative thought patterns.
- Behavioral Activation: Increasing engagement in positive and rewarding activities.
- Exposure Therapy: Gradually exposing oneself to feared situations or objects to reduce anxiety.
- Problem-Solving: Developing practical solutions to specific problems.
The Potential of CBT Apps
CBT apps offer a convenient and accessible way to learn and practice CBT skills. They can be used as a self-help tool or as a supplement to traditional therapy. These apps often include features such as:
- Mood Tracking: Monitoring mood and identifying patterns.
- Thought Diaries: Recording and challenging negative thoughts.
- Relaxation Exercises: Practicing relaxation techniques to reduce stress and anxiety.
- Educational Content: Learning about CBT principles and techniques.
Benefits of CBT Apps
- Accessibility: CBT apps can be accessed anytime, anywhere, making them a convenient option for people who have difficulty attending traditional therapy sessions.
- Affordability: Many CBT apps are free or low-cost, making them an affordable option for people who may not be able to afford traditional therapy.
- Privacy: Some people may feel more comfortable using a CBT app than attending traditional therapy sessions due to privacy concerns.
- Self-Paced Learning: CBT apps allow people to learn at their own pace, revisiting content as needed.
Challenges of CBT Apps
Despite their potential, CBT apps also have some challenges:
- Engagement: Maintaining engagement with a CBT app can be difficult, especially without the support of a therapist.
- Effectiveness: The effectiveness of CBT apps can vary depending on the app and the individual using it.
- Regulation: The mental health app market is largely unregulated, so it’s important to choose apps that are evidence-based and developed by qualified professionals.
Existing CBT Apps: A Glimpse into the Digital Mental Health Landscape
Several CBT apps are currently available, each offering unique features and approaches to mental health support. Here’s a brief overview of some notable examples:

The Future of Mental Health: Integrating Technology and Therapy
The development and testing of CBT apps represent an exciting step forward in the field of mental health. By leveraging technology, these apps have the potential to:
- Increase Access to Care: CBT apps can reach people who may not have access to traditional therapy due to geographical, financial, or other barriers.
- Provide Early Intervention: By identifying and supporting individuals at high risk of depression, CBT apps can help prevent the onset of more severe mental health problems.
- Personalize Treatment: CBT apps can be tailored to individual needs and preferences, providing a more personalized and effective treatment experience.
- Reduce the Burden on Healthcare Systems: By providing self-help tools and resources, CBT apps can reduce the demand for traditional mental health services.
However, it’s important to recognize that CBT apps are not a replacement for traditional therapy. They should be used as part of a comprehensive mental health plan, in consultation with a qualified mental health professional.
As technology continues to evolve, we can expect to see even more innovative approaches to mental health care. By integrating technology and therapy, we can create a more accessible, affordable, and effective mental health system for all.
