Acceptance as a possible link between past psychedelic experiences and psychological flexibility

Area of Science:

• Psychology
• Neuroscience
• Psychiatry

Background:

• Psychedelic experiences are anecdotally linked to lasting mental well-being improvements.
• The mechanisms connecting psychedelic use to psychological flexibility (PF) and well-being remain unclear.
• Psychological inflexibility (PI) is associated with poorer mental health outcomes.

Purpose of the Study:

• To investigate associations between psychedelic experience components, frequency of use, and psychological flexibility (PF) and inflexibility (PI).
• To examine the relationship between PF/PI and mental well-being and ill-being.
• To explore if PF mediates the link between psychedelic use and mental health outcomes.

Main Methods:

• Cross-sectional internet survey of 629 participants with classical psychedelic experience.
• Network analysis to examine associations between psychedelic experience features, PF/PI components, and well-being.
• Mediation analyses to test the role of PF in psychedelic use and mental health relationships.

Main Results:

• Psychological insight from psychedelic experiences was linked to the PF component Acceptance.
• No significant association was found between the frequency of past psychedelic use and PF.
• PF was found to mediate the relationship between past psychedelic use and both mental well-being and ill-being.

Conclusions:

• The quality and depth of psychedelic experiences, especially psychological insights, are more influential than frequency of use for enhancing psychological flexibility (PF).
• PF, particularly Acceptance, plays a crucial role in mediating the positive mental health effects of psychedelic use.
• Understanding PF as a multidimensional construct is vital for elucidating the long-term mental health benefits of psychedelics.
