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.

Trial outcomes

Primary outcomes

1

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.

Time frame
Change from baseline to 1-week, 4 weeks, and 6 months post-dosing
2

PTSD Checklist for DSM-5 (PCL-5)

A 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD.

Time frame
Change from baseline to 1-week, 4 weeks, and 3 months, and 6 months post-dosing

Secondary outcomes

1

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.

Time frame
Change from baseline to 1-week, 4 weeks, 3 months, and 6 months post-dosing
2

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

Time frame
Change from baseline to 1-week, 4 weeks, and 3 months, and 6 months post-dosing
3

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.

Time frame
Change from baseline to 1-week, 4 weeks, and 3 months, and 6 months post-dosing
4

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.

Time frame
Change from baseline to 1-week, 4 weeks, and 6 months post-dosing

Other outcomes

1

Blood biomarkers

To explore blood biomarkers related to PTSD, brain injury, inflammation, oxidative stress, and growth factors following psilocybin-assisted therapy

Time frame
Change from baseline to 1-week, 4 weeks, and 6 months post-dosing
