Mean Score of Acceptability Ratings on Reactions to Research Participation Questionnaire Revised (RRPQR) Primary · At Week 1 post dosing session

The RRPQ-R is a validated 23-item instrument designed to assess participants' experiences and perceptions of research participation. It comprises five subscales: participation (7 items, range 7-35), personal benefit (5 items, range 5-25), emotional reactions (6 items, range 6-30), perceived drawbacks (3 items, range 3-15), and global evaluation (2 items, range 2-10). Items are rated on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Higher scores on participation, personal benefit, and global evaluation indicate more positive perceptions, while higher scores on emotional

Change in Global Quality Life Score as Assessed by Functional Assessment of Chronic Illness Therapy - Palliative Care 14 (FACIT-Pal 14) Secondary · At Baseline, and weeks 1, 3, and 7

The FACIT-Pal-14 is a validated 14-item measure of quality of life in palliative care populations. Items assess physical, emotional, social, and functional well-being over the past 7 days using a 5-point Likert scale (0 = not at all to 4 = very much). Scores are summed to produce a total score ranging from 0 to 56, with higher scores reflecting better quality of life. Subscale scores are not typically reported separately, but can be derived if needed by summing relevant items. The measure is widely used in palliative and supportive care research to evaluate patient-centered outcomes.

The PROMIS Pain Interference Scale (8a) is a validated 8-item instrument assessing the extent to which pain hinders engagement in social, emotional, cognitive, and physical activities. Items are rated over the past 7 days on a 5-point Likert scale (1 = not at all to 5 = very much). Raw scores range from 8 to 40 and are converted to standardized T-scores (mean = 50, SD = 10) using PROMIS scoring manuals. Higher scores indicate greater interference of pain with daily functioning. The measure is administered only if pain is reported and allows both raw and T-score interpretations to facilitate co

It is a self-report questionnaire consisting of 14 items, and subjects rate how they felt during the previous week on a 4-point Likert scale. The HADS consists of an anxiety and depression subscale (0-21 points each), and total scores can range from 0 to 42. Higher scores indicate more severe depression and anxiety.

Change in Life Attitude Profile - Revised, Death Acceptance Subscale (LAP-R) Score Secondary · At Baseline, and weeks 1, 3, and 7

The LAP-R Death Acceptance subscale is a validated 8-item measure assessing acceptance of and anxiety about death. Items are rated on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree). Subscale scores are calculated by summing item responses, yielding a total range of 9 to 56, with higher scores reflecting greater acceptance of death and lower death-related anxiety. The measure is commonly used in palliative care and existential research to evaluate psycho-existential adjustment in serious illness.

Challenging Experience Questionnaire (CEQ) Score Secondary · Immediately after the intervention, at the end of the dosing day

The CEQ is a validated 26-item instrument assessing psychologically and somatically difficult aspects of psilocybin experiences. It consists of seven subscales: grief (3 items, range 3-15), fear (6 items, range 6-30), death (3 items, range 3-15), insanity (3 items, range 3-15), isolation (3 items, range 3-15), physical distress (3 items, range 3-15), and paranoia (5 items, range 5-25). Items are rated on a 5-point Likert scale (1 = not at all to 5 = extremely). Subscale scores are computed by summing responses within each domain, with higher scores indicating more challenging experiences. A to

Change in Social Isolation Scale (SIS) Score Secondary · At Baseline, and weeks 1, 3, and 7

The PROMIS Social Isolation Scale-6a is a validated 6-item short form that measures perceived social disconnection, including feelings of exclusion, detachment, and lack of belonging. Items are rated on a 5-point Likert scale (1 = never to 5 = always). Raw scores range from 6 to 30 and are converted to standardized T-scores (mean = 50, SD = 10) based on PROMIS scoring guidelines. Higher scores represent greater perceived social isolation. The measure is widely used in psychosocial and palliative care research to assess the impact of illness on social well-being.
