Awards & highlights


This trial is testing a stepped-care approach to treating PTSD symptoms in stem cell transplant survivors, which may help develop targeted treatments for PTSD.

Who is the study for?
This trial is for cancer survivors who've had a stem cell transplant 1-5 years ago and are showing signs of PTSD but haven't received CBT for it. They must be able to use a smart device, read/write English, have their oncologist's approval, and not be severely psychologically impaired.Check my eligibility
What is being tested?
The study tests a mobile app called Cancer Distress Coach (CaDC), with or without additional coaching or mobile CBT (mCBT), against usual care. Participants will be randomly assigned to treatments and assessed over 6 months to see if the app helps reduce PTSD symptoms.See study design
What are the potential side effects?
Since this trial involves non-medical interventions like apps and coaching, traditional side effects related to drugs are not expected. However, participants may experience emotional discomfort while discussing traumatic experiences.
