TRT™ — The New Standard for Mental Health Recovery. A therapy, not a self-help programme.
HomePrevention

Prevention · AnxApp

Prevention starts with noticing earlier.

AnxApp gives individuals, families and organisations a practical way to recognise anxiety-related risk sooner, and to connect that insight with prevention or TRT™ recovery support.

The earlier risk is visible, the more choice there is about what to do next.

Why early action matters

Stress and anxiety rarely arrive wearing a label.

Anxiety-related experiences can build quietly alongside poor sleep, fatigue, avoidance or difficulty concentrating. By the time they are obvious, they may already be shaping work, family life and confidence. Recognising risk sooner opens the door to support while there is room to act.

  1. 01

    Recognise

    Confidential predisposition and current-symptom assessments bring anxiety-related risk into view earlier, rather than waiting for it to become the only thing you notice.

  2. 02

    Understand

    Results guide a personalised prevention or recovery pathway, so insight leads somewhere practical instead of ending with a score.

  3. 03

    Act

    Science-led resources, Ask Chuck guidance and, where recovery is the goal, the Institute's TRT™ recovery programme.

Where to start

Two routes in, one purpose.

AnxApp Individual website preview

For individuals & families

Individual access

A private, personal route to understanding anxiety predisposition and current symptoms, with a personalised prevention pathway. No employer involvement needed.

Inside workplace deployment

Personal support stays personal. Leadership sees the bigger picture.

Each role gets what it needs, with a clear boundary between private member support and organisational insight.

Confidential member assessment

Members see their own results and pathway. No individual answers or results are shared with management.

Organisational aggregate insight

HR and leadership see anonymised patterns, department insight where privacy thresholds permit (minimum reporting group of 10) and prioritised recommendations.

Manager signposting training

An introduction plus a 12-part programme in Science, Recognition and Signposting for Mental Health Conditions, with conversation guides and escalation support.

Chuck, the Ask Chuck character

Ask Chuck · Our knowledge, made accessible

32 years of expertise.
Guidance you can ask for.

Ask Chuck offers guidance on symptoms, thoughts, physical and mental health concerns, relationships and everyday challenges. It brings together our team’s research, data, TRT™ recovery material and coaching knowledge gathered through 32 years of practice, making that experience accessible through conversation.

Chuck is the interface, not the expert. The expertise belongs to our team and the material we have developed. His role is to make that knowledge easier to find, understand and use as part of your prevention or recovery pathway.

Explore Ask Chuck through AnxApp (opens in a new tab)

Not an AI therapist. A guide to our knowledge.

Ask Chuck is not presented as an independent intelligence creating its own therapy or replacing our team. It provides a guided way into the Institute’s existing research, teaching and practical coaching. The knowledge comes from our work; Chuck makes it accessible through conversation.

  • Explore symptoms, troubling thoughts and questions about physical or mental wellbeing.
  • Find guidance on relationships, everyday challenges and your prevention or recovery pathway.
  • Access research, data and practical coaching knowledge gathered through 32 years of our team's practice.
