Building an AI Driven Chatbot for PTSD Assessment

Project completed!

Post-traumatic-stress-disorder (PTSD) is a global problem that affects millions of people. 32 Omdena Collaborators prototyped a machine learning driven chatbot for PTSD assessment in war and refugee zones. The unique aspect of the project was that the team started without access to a data set but through collaborative efforts the community found sources with suitable patient data sets.


Leveraging AI for mental health

PTSD is affecting millions of people globally and can be triggered when an individual experiences a severely traumatic event. Instead of the trauma leveling off, it becomes a mental health condition. Symptoms include panic attacks, anxiety, uncontrollable thoughts, and more. Especially, in low resource settings, such as war and refugee zones, PTSD is a significant problem. This is due to the lack of doctors and psychologists who can accurately assess and treat people at risk. The result is that most people are not even aware of the possibility that they struggle with PTSD.

In the video below, Christoph von Toggenburg, who partnered up with Omdena as the CEO of Colour the World Foundation describes the magnitude of the problem and his personal experience with PTSD. In 2009, he and his team got caught in an armed ambush in the Central African Republic.


The solution: A chatbot for PTSD assessment

The community worked on the following approaches to research and prototype the chatbot:

  • Getting access to patient data sets through community collaboration.
  • Using MLFlow to structure a Machine Learning project and support the backend of the risk classifier chatbot.
  • Applying risk assessment of PTSD using linear classifiers in NLP.
  • Integrating all tasks into an intelligent NLP and machine-learning-driven chatbot.

The impact

PTSD in low resource settings

Challenge partner Christoph von Toggenburg experienced PTSD himself. A truck he was riding in while on an emergency mission in the Central African Republic was ambushed. Luckily, he received treatment for it and experiences almost no symptoms today.

Now, Christoph’s project BEATrauma is an initiative to help victims with PTSD all around the world. His vision is to create a mobile app chatbot to converse with users and determine a risk assessment for PTSD. PTSD is just one example where AI can be applied to improve mental health and help people in need.

We are thanking all community collaborators for the amazing work done!
