About this trial
The goal of this randomized controlled trial is to evaluate the efficacy of psilocybin administered with Acceptance and Commitment Therapy (ACT) as an intervention to reduce post-traumatic stress disorder (PTSD) symptom burden in adult (aged 18-65) survivors of intimate partner violence (IPV).
This trail will test the following 2 aims:
AIM 1 : To compare the efficacy of a therapeutic psilocybin dose at improving outcomes on the PCL-5 and CAPS-5 as compared to an active control psilocybin dose in IPV survivors with chronic PTSD.
AIM 2: To evaluate the efficacy of psilocybin on quality of life, cognitive function, motor ability, depression, anxiety, and cognitive flexibility.
Participants will be asked to:
* Complete a 2 part screening process * Attend a baseline assessment * Complete a psychoeducation preparation session(s) * Attend psilocybin administration session (receive high dose \[25mg\] or low dose psilocybin \[1mg\]) * Complete 5-6 weekly sessions of ACT * Repeat outcome measures at 1-week, 4 weeks, 3 months (online questionnaires only), and 6 months post-psilocybin administration.

Treatment groups
Trial outcomes
Primary outcomes
Clinician-Administered PTSD Scale for DSM-5 (CAPS-5)
A clinician-administered, 30-item structured interview to diagnose and assess severity of PTSD symptoms in patients. It is widely used and validated, and is considered the gold standard PTSD diagnostic tool.
PTSD Checklist for DSM-5 (PCL-5)
A 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD.
Secondary outcomes
Montgomery-Åsberg Depression Rating Scale, Self-Reported (MADRS-S)
A self-reported, 9-item assessment of depressive symptoms using a recall period of the past 7 days. This tool elicits a total score ranging from 0-54, with higher scores indicating greater depression.
Generalized Anxiety Disorder-7 (GAD-7)
A 7-item self-reported questionnaire for measuring the severity of generalized anxiety disorder. Individuals rate how often they have been bothered by seven listed problems and score their responses from 0 ("not at all") to 3 ("nearly every day"). Total scores for anxiety severity are: 0-4: minimal anxiety; 5-9: mild; 10-14: moderate; 15-21: severe anxiety
Rivermead Post-Concussion Symptoms Questionnaire (RPQ)
A self-reported, 16-item questionnaire used to assess severity of 16 commonly experienced PPCS symptoms using a scale of 0 ("not experienced") to 4 ("severe problem"), with higher scores indicating greater PPCS symptom burden.
The Acceptance and Action Questionnaire II (AAQ-II)
A 7-item questionnaire measuring psychological flexibility. Scores range from 0 to 49 with higher scores indicating greater psychological flexibility.
Other outcomes
Blood biomarkers
To explore blood biomarkers related to PTSD, brain injury, inflammation, oxidative stress, and growth factors following psilocybin-assisted therapy
