The State-Trait Anxiety Inventory (STAI) is a commonly used measure of trait and state anxiety. The scale is based on a 4-point Likert scale and consists of 40 self-report questions. The STAI measures two types of anxiety – state anxiety, anxiety about an event, and trait anxiety, anxiety level as a personal characteristic.

Lysergic acid diethylamide-assisted therapy in patients with anxiety with and without a life-threatening illness A randomized, double-blind, placebo-controlled Phase II studyThis double-blind cross-over trial (n=42) finds that LSD (2x 200 μg) significantly reduced anxiety (STAI-G) scores up to three months after treatment. The patients, both with and without a life-threatening illness, also improved on measures of depression (HAM-D, BDI). Those with more subjective drug effects and mystical-type experiences had better outcomes.
MDMA-assisted psychotherapy for treatment of anxiety and other psychological distress related to life-threatening illnesses: a randomized pilot study
This double-blind, placebo-controlled study (n=18) with MDMA (125mg, 2-3 sessions) in combination with psychotherapy found no significant difference in anxiety in a population with life-threatening illnesses. Though no significant group difference was found (p=.056), the study showed a large effect size (g=1.03) and a larger sample size might find a significant difference (favouring MDMA).
MDMA-assisted psychotherapy using low doses in a small sample of women with chronic posttraumatic stress disorder

Pilot study of psilocybin treatment for anxiety in patients with advanced-stage cancer
This is the first (modern) double-blind placebo-controlled study (n=12) of psilocybin (14mg/70kg) for the treatment of (end-of-life) anxiety (and depression) related to cancer. Treatment led to a significant reduction in anxiety symptoms up to three months after treatment and improvements in depressive symptoms reached significance after six months.
Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees
This naturalistic study (n=52) assessed the effects psilocybin has on measures of state and trait anxiety among retreat participants with subclinical levels of anxiety. Average psilocin consumption across individuals was 27.1 mg. The morning after the ceremony, medium reductions in both state and trait anxiety were observed and these reductions persisted for 1-week. Higher ratings of ego dissolution and changes in neuroticism were the strongest predictors of these reductions.
Psychedelic Microdosing, Mindfulness, and Anxiety: A Cross-Sectional Mediation Study
This cross-sectional study assessed the relationship between microdosing and trait anxiety through an online survey with current microdosers (n = 186), former microdosers (n = 77) and microdosing-naïve controls (n = 234). Current and former microdosers reported lower STAI-T scores compared to microdosing-naïve controls while associations of current and former microdosing with trait anxiety were mediated by trait mindfulness. All associations between microdosing and STAI-T scores became non-significant when participants with previous macrodose experience (n = 386) were excluded.
