CBT Therapy App: Cognitive Behavioural Therapy in Your Pocket

Cognitive Behavioural Therapy is the most extensively researched and validated form of psychotherapy in the world. Hundreds of clinical trials have confirmed its effectiveness for anxiety, depression, OCD, PTSD, insomnia and more. Mentis makes CBT accessible to anyone with a smartphone — no waiting lists, no prohibitive costs.

What Is Cognitive Behavioural Therapy?

CBT is based on the insight that our thoughts, feelings and behaviours are interconnected. When we hold unhelpful thought patterns — "I always fail", "Everyone is judging me", "The worst will definitely happen" — these generate negative emotions and avoidant behaviours that reinforce the original thought. CBT breaks this cycle by teaching you to identify and challenge these patterns.

Core CBT Techniques Used in Mentis

CBT for Anxiety vs CBT for Depression

While the core model is the same, CBT for anxiety focuses primarily on identifying threat overestimation and avoidance, while CBT for depression places more emphasis on behavioural activation and addressing hopelessness. Mentis adapts the approach based on your specific goals.

📚 A 2021 meta-analysis of 41 randomised trials found digital CBT interventions reduced symptoms of anxiety and depression by an average of 50% over 8 weeks.

Is Digital CBT as Effective as Face-to-Face Therapy?

For mild to moderate symptoms, research shows digital CBT produces comparable outcomes to therapist-delivered CBT, particularly when users are engaged and consistent. Mentis enhances effectiveness by combining CBT with daily mood tracking, personalised plans, and AI-driven adaptation — creating a more responsive programme than static self-help books or generic apps.
