Psilocybin-assisted psychotherapy improves psychiatric symptoms across multiple dimensions in patients with cancer
This pooled analysis of two Phase II RCTs (n=79) evaluates psilocybin-assisted psychotherapy (PAP/PAT) for cancer-related distress. PAT significantly improves anxiety, depression, interpersonal sensitivity, hostility, obsession–compulsion, and somatization without inducing lasting phobia, paranoia, or psychosis.

Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer: A randomized double-blind trial
This study (n=51) investigated the effects of a high dose of psilocybin (22 or 30mg/70kg) on depression and anxiety in patients with life-threatening cancer. It found significant improvements in clinician- and self-administered measures of depression and anxiety, even without psychotherapy (as many other studies provide). At 6-month follow-up, these changes were sustained, with about 80% of participants continuing to show clinically significant decreases in depressed mood and anxiety.

Measures Used

Hamilton Depression Rating Scale
The Hamilton Depression Rating Scale (HDRS) is a multiple item questionnaire used to provide an indication of depression, and as a guide to evaluating recovery. The scale consists of 17 items which each item being scoring on a 3 or 5 point scale. The higher the score, the more likely a person is depressed.

Hamilton Anxiety Scale
The Hamilton Anxiety Scale (HAM-A) was one of the first rating scales developed to measure the severity of anxiety symptoms and is still widely used today in both clinical and research settings.
