RESEARCH INSTRUMENTS

APEQ

The Acceptance/Avoidance-Promoting Experiences Questionnaire (APEQ) is a psychometric self-report tool for measuring aspects of the acute psychedelic experience that are associated with longer-term changes in psychological flexibility.

English and German versions of the 32-item APEQ and the 12-item short form APEQ-S were validated with the data collected in the Psychedelic Experience Survey. The validation study is expected to be published in 2021.

A Spanish translation of the APEQ is currently being validated.
