Additional MDMA-assisted Psychotherapy for People Who Relapsed After MDMA-assisted Psychotherapy Trial

This study will consist of a single session of MDMA-assisted therapy with a full dose of MDMA for people who took part in a study of MDMA-assisted therapy in people with PTSD whose PTSD symptoms returned to higher levels at least a year after the first MDMA sessions.

The single session will be performed by the same pair of therapists who performed the sessions in the first study. People will have a preparatory session, the MDMA-assisted session and three non-drug sessions afterward. Their PTSD symptoms and symptoms of depression will be measured at the start of this study and two and 12 months after the session.

Measures Used

Clinician-Administered PTSD Scale for DSM-5
The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is often considered the gold standard in PTSD assessment. The 30-item structured interview was developed by staff at the U.S. Department of Veterans Affairs National Centre for PTSD. CAPS can be used to make a current diagnosis, lifetime diagnosis or assess PTSD symptoms over the past week in accordance with DSM-5 criteria.

Beck Depression Inventory
The Beck Depression Inventory (BDI) contains 21 self-report items, completed using a multiple-choice format. Scores range from 0-63 with higher scores associated with more severe depression.

States of Consciousness Questionnaire
The States of Consciousness Questionnaire (SOCQ) was developed to assess the occurrence features of the change in consciousness induced by psilocybin and includes the Mystical Experience Questionnaire (MEQ). The SOCQ consists of 100 items, 43 of which are from the MEQ.
