Abstract
Rationale: Psychedelic-assisted therapy is increasingly applied within mental health treatment.
Objectives: This study focused on factors moderating changes in the acute and long-term effects of an individual psilocybin-assisted program on depression, anxiety, PTSD and personality structures by including demographic factors, subjective experience and degree of mystical type experiences during the dosing, as well as emotional breakthrough and personal growth after the program.
Methods: At baseline, 1 week and 3 months after the psilocybin program participants completed the Generalized Anxiety Disorder Assessment (GAD-7), Patient Health Questionnaire (PHQ-9), PTSD Checklist for DSM-5 (PCL-5) and NEO Five-Factor Inventory-3 (NEO-FFI-3). In addition, after the dosing the Mystical Experiences Questionnaire (MEQ-30), Posttraumatic Growth Inventory (PTGI) and Emotional Breakthrough Inventory (EBI) were administered. Moderation effects were established using linear mixed-model analysis.
Results: A single high dose of psilocybin in combination with therapy was found to lower symptoms of anxiety, depression, PTSD and neuroticism over a period of 3-months. Scores on openness and conscientiousness increased after the treatment only. Participants reported mystical type experiences, emotional breakthrough and personal growth. These subjective experiences together with demographic factors were moderating the observed positive changes.
Conclusions: Findings indicate that individual psilocybin-assisted therapy has the potential for beneficial effects on mood and personality characteristics. Moreover, the study highlights the importance of subjective experiences and demographic factors in moderating this effect. This study adds to the ongoing research on psilocybin-assisted therapy by investigating contributing factors for optimizing this evolving type of therapy.
期刊介绍：
Official Journal of the European Behavioural Pharmacology Society (EBPS)
Psychopharmacology is an international journal that covers the broad topic of elucidating mechanisms by which drugs affect behavior. The scope of the journal encompasses the following fields:
Human Psychopharmacology: Experimental
This section includes manuscripts describing the effects of drugs on mood, behavior, cognition and physiology in humans. The journal encourages submissions that involve brain imaging, genetics, neuroendocrinology, and developmental topics. Usually manuscripts in this section describe studies conducted under controlled conditions, but occasionally descriptive or observational studies are also considered.
Human Psychopharmacology: Clinical and Translational
This section comprises studies addressing the broad intersection of drugs and psychiatric illness. This includes not only clinical trials and studies of drug usage and metabolism, drug surveillance, and pharmacoepidemiology, but also work utilizing the entire range of clinically relevant methodologies, including neuroimaging, pharmacogenetics, cognitive science, biomarkers, and others. Work directed toward the translation of preclinical to clinical knowledge is especially encouraged. The key feature of submissions to this section is that they involve a focus on clinical aspects.
Preclinical psychopharmacology: Behavioral and Neural
This section considers reports on the effects of compounds with defined chemical structures on any aspect of behavior, in particular when correlated with neurochemical effects, in species other than humans. Manuscripts containing neuroscientific techniques in combination with behavior are welcome. We encourage reports of studies that provide insight into the mechanisms of drug action, at the behavioral and molecular levels.
Preclinical Psychopharmacology: Translational
This section considers manuscripts that enhance the confidence in a central mechanism that could be of therapeutic value for psychiatric or neurological patients, using disease-relevant preclinical models and tests, or that report on preclinical manipulations and challenges that have the potential to be translated to the clinic. Studies aiming at the refinement of preclinical models based upon clinical findings (back-translation) will also be considered. The journal particularly encourages submissions that integrate measures of target tissue exposure, activity on the molecular target and/or modulation of the targeted biochemical pathways.
Preclinical Psychopharmacology: Molecular, Genetic and Epigenetic
This section focuses on the molecular and cellular actions of neuropharmacological agents / drugs, and the identification / validation of drug targets affecting the CNS in health and disease. We particularly encourage studies that provide insight into the mechanisms of drug action at the molecular level. Manuscripts containing evidence for genetic or epigenetic effects on neurochemistry or behavior are welcome.
