Thanks very much.
In this particular Internet-based intervention—MMTT, I'll call it for short—all of them are inspired and validated interventions. The journaling activity is part of a cognitive behaviour therapy standard approach, the automatic thought record. It is to take those six principles that I described and apply them to everyday stressors that the individual is experiencing, using those concepts and applying them to regulate themselves to be able to manage their distress, reflect, and respond in a more adaptive way. That is part of typical approaches, but we're using the mindfulness language and specifically making use of it and applying it to that journaling activity. However, the journaling activity, broadly speaking, is a well-validated and researched intervention.
We also include a specific practice that we developed here at Western whereby we can determine the level of concentration experienced during the meditation. It's a self-report methodology, but we're validating it against various experimental methodologies, including collecting EEG, and we're able to predict, for example, the brain state from the self-report, and whether the person was concentrating or distracted during the meditation. As they sit quietly and attend, for example, to their breath, their mind will wander, and it may wander towards the trauma and intrusive memory, but in terms of the degree to which it does so, we can provide some prompts, some cues, to bring them back to the breath, back to the target of their attention.
Finally, the different guided meditations that we include have all been used in various formats, most especially the well-researched mindfulness-based stress reduction and mindfulness-based cognitive therapy. Each of the interventions available through the website has been well researched in different domains with various populations, including PTSD, but also, as you say, various anxiety disorders, depressive disorders, dissociative disorders, substance abuse disorders, which PTSD is typically comorbid with.
