Outcome Measures

Primary Outcomes (5)

  • Assessing change in PTSD diagnosis and its symptom severity from pre-treatment to post-treatment using the CAPS-5 assessment.

    PTSD diagnosis will be assessed using the Clinician-Administered PTSD Scale (CAPS-5) for DSM-5 Total Severity Score, a well-validated, semi-structured clinician interview that determines the presence and severity of PTSD symptoms and diagnosis consistent with the DSM-5 and allows for assessing changes in symptom severity over time.

    Administered at a pre-treatment visit (at the initial screening visit); and at the four post-treatment visits (one week post-treatment and 3-, 6-, and 9-months post-treatment visits).

  • Assessing change in PTSD diagnosis and its symptom severity throughout the study using the PCL-5 assessment

    The PCL-5 is a 20-item self-report measure that assesses DSM-5 symptoms of PTSD. The PCL-5 is used to monitor symptom change during and after treatment, screen individuals for PTSD, and make a provisional PTSD diagnosis. This assessment will also be used as a safety measure at all visits by assessing PTSD symptom severity.

    Administered at every study visit: both pre-treatment visits (the initial screening and baseline visit); during the 12-week treatment phase (all twelve weekly visits); and the four post-treatment visits (one week post-treatment and 3-, 6-, and 9-months

  • Assessing Suicidality over time using the C-SSRS assessment.

    The Columbia Suicide Severity Rating Scale (C-SSRS) is a clinician-administered interview assessing suicidal thoughts and behaviors over time. A baseline form is used to assess lifetime suicidal ideation, intensity, and behavior, and can be compared to current suicidal ideation and intensity assessed over the clinical trial.

    Administered at a pre-treatment visit (at the initial screening visit); and at the four post-treatment visits (one week post-treatment and 3-, 6-, and 9-months post-treatment visits).

  • Assessing Suicidality throughout the study using the SBQ-R assessment.

    The Suicide Behavior Questionnaire-Revised (SBQ-R) is a brief (4-item), self-administered questionnaire that taps into four dimensions of suicidality (lifetime ideation/attempt, frequency of recent ideation, risk of suicide attempt and self-reported likelihood of future suicidal behavior). This assessment will also be used as a safety measure at all visits by assessing suicidality.

    Administered at every study visit: both pre-treatment visits (the initial screening and baseline visit); during the 12-week treatment phase (all twelve weekly visits); and the four post-treatment visits (one week post-treatment and 3-, 6-, and 9-months

  • Assessing mood and anxiety symptoms throughout the study using the BDI-II and STAI-Y Questionnaires.

    The Beck Depression Inventory-II (BDI-II) is a self-report depression checklist which assesses neurovegetative depressive symptoms. One item asks specifically about suicidal thoughts and will also be checked at every study visit as a safety measure. The State Trait Anxiety Inventory-Form Y (STAI-Y) is a 40-item questionnaire with two scales assessing state and trait anxiety (somatic and cognitive symptoms).

    Administered at every study visit: both pre-treatment visits (the initial screening and baseline visit); during the 12-week treatment phase (all twelve weekly visits); and the four post-treatment visits (one week post-treatment and 3-, 6-, and 9-months

Secondary Outcomes (16)

  • Assess emotional state pre- and post-treatment using the PANAS questionnaire.

    Administered at a pre-treatment visit (at the baseline visit); and at the first post-treatment visit (one week post-treatment).

  • Assess feelings of loneliness pre- and post-treatment using UCLA's 3-ILS assessment.

    Administered at a pre-treatment visit (at the initial screening visit); and at the first post-treatment visit (one week post-treatment).

  • Assess dissociative symptoms pre- and post-treatment using the MDI and DSS assessments.

    Administered at a pre-treatment visit (at the baseline visit); and at the four post-treatment visits (one week post-treatment, and 3-, 6-, and 9-months post-treatment).

  • Assess drug effects, liking, and symptoms after cannabis administration using the SCERF and SES visual analog scales.

    Administered after cannabis administration; therefore, administered at the baseline visit and electronically during the 12-week treatment phase (at all twelve weekly visits).

  • Assess demographics using a self-report assessment

    Administered once at a pre-treatment visit, specifically at the initial screening visit.

  • +11 more secondary outcomes
