A Platform with scientific data

Use the ASDB to compare what experiences are elicited by which consciousness modifying techniques

The
ASDB
Project

The Altered States Database (ASDB) is an open-science project managed by the scientific collaboration CIRCE that aims to facilitate access for researcher and laypersons to scientific data on various pharmacological and non-pharmacological induction methods for altered states of consciousness (ASCs).

This database only contains psychometric data published in peer-reviewed (quality controlled) scientific publications and is updated annually following a systematic literature review according to the PRISMA 2020 Statement Guidelines.

Our mission is to support rigorous research on human consciousness. As interest in psychedelics in therapy grows, we enhance data comparability by offering comparison data and optimizing study designs with suitable questionnaire tools.

Access the database through the selection field above. Find plain data on OSF. Find Resources for Scientists linked below.

RESOURCES FOR SCIENTISTS

In our Collection of Questionnaires to assess ASCs, we provide:

Up-to-date overview of questionnaire tools to assess ASC phenomena
Background information to help you choose which tools you want to use in your study
Information on the history of the questionnaires and different existing versions
Tips for the analysis (to avoid mistakes)
References to translations and validations of the questionnaires

We aim to extend these resources by:

Printable PDFs of questionnaires (wherever copyrights allow this)
Online implementations of the questionnaires
Analysis scripts

If you have further information or material, we are happy about your feedback, extensions, and could also make materials available.

We offer workshops for scientists and industry, as well as consultation services by our scientists through CIRCE e.V.

Visit AXP, our Citizen Science project, to quantify diverse ASC experiences.

The App was developed by Tim Hirschfeld with R Shiny and Echarts4r on behalf of CIRCE. Footer animation was adopted from the Wavey Footer Experiment by James Hancock.

In its judgment of May 12, 1998 - 312 O 85/98 - the Regional Court of Hamburg ruled that the inclusion of a link may entail co-responsibility for the content of the linked page. According to the court, this can only be prevented by expressly distancing oneself from these contents.
