Trial Outcomes & Findings for Study of 3,4-Methylenedioxymethamphetamine-assisted Psychotherapy in People With Posttraumatic Stress Disorder (NCT NCT00353938)

NCT ID: NCT00353938

Last Updated: 2024-07-15

Results Overview

The CAPS-IV is a structured clinical interview designed to assess the symptoms and severity of PTSD. The CAPS-IV provides a means to evaluate the frequency and intensity dimensions of each symptom, the impact of symptoms on the patient's social and occupational functioning, the overall severity of the symptom complex, global improvement since baseline, and the validity of the ratings obtained. Total severity scores range from 0 to 136, with higher scores indicating greater severity of PTSD symptoms.

Participant Flow

Participants were recruited by calling for referrals from psychiatric hospitals, trauma counseling centers, psychiatrists and psychotherapists in the German-speaking part of Switzerland.

Only active control participants from Stage 1 entered into open-label Stage 2 and only participants who received full dose in Stage1 or Stage 2 and did not respond with significant improvement were offered the opportunity to partake in open-label Stage 3.

SECONDARY outcome

Timeframe: Less than 4 weeks before first experimental session (Baseline) to 3 weeks post 3rd experimental session (Primary Endpoint)

The Posstraumatic Stress Diagnostic Scale (PSD) is a 49-item self-report instrument to aid in the diagnosis of PTSD. Questions are asked about symptoms experienced and participants respond on a scale from 0 ("not at all or only one time") to 3 ("5 or more times a week/almost always"). Items are summed to create a total score that ranges from 0 to 51, with higher scores indicating more PTSD symptoms.
