Perspectives is an app that delivers cognitive behavioral therapy for conditions like OCD, depression, and anxiety. It is currently under clinical trial towards FDA clearance at Massachusetts General Hospital in Boston. If its efficacy is proven, clinicians will be able to prescribe it to their patients.

How do you conduct user research among people with a diagnosis? These are some of the topics we will touch on in this talk.
