Permitted Uses
All my measures are free to use for non-commercial purposes, including student projects and academic research. You do not need to request my permission for these uses.
If you are a psychological practitioner, you are welcome to use any of my measures in your clinical practice — including private sector work — where the purpose is to assess or track client progress. Again, no permission is needed.
If you would like to use my measures in any other context involving commercial gain, you must contact me for permission, and may not proceed without my explicit written agreement.
For the ČEFSA measure(s): you may find this wiki helpful for choosing between versions and finding translations.
When using a measure, please cite its original paper.
Access
I always publish my measures in full in Open Access journals, in line with Open Science principles.
This means that you do not need to request copies: full versions are included with the published article. Please check for an ‘Appendix’ or ‘Supplementary Material’ file, or scroll to the very end of the article (after the References).
Translations
If you are planning to translate the ČEFSA, please check first whether a translation in your intended language is already underway: https://osf.io/t2re7/wiki/home/
If your translation is not already listed, please let me know so I can add it to the wiki.
-
The original 35-item self-report measure designed to identify and track Felt Sense of Anomaly (FSA)-type dissociative experiences.
Validated for ages 18+, including general population and clinical (psychosis) groups.
-
An age-invariant 14-item version of the ČEFSA, with accompanying scoring guidance (notinterpretable as a ‘clinical cut-off’).
Validated for ages 13+, including clinical and general population respondents.
-
A 13-item self-report measure of cognitive appraisals of dissociative experiences.
Initially validated in a psychosis group, but can be used outside of this context.
-
6-item self-report measure of behavioural responses to dissociation.
See ‘Appendix A. Supplementary data’ in this paper.
-
A 5-item brief screening tool to establish whether Felt Sense of Anomaly-type dissociation should be considered.
-
A data-driven (‘bottom up’) approach to attempting to capture the breadth of dissociative experiences.
NB: this measure was designed to be atheoretical and broad. Recently, my position has changed, and I now view this as a limitation, since we are learning that there may be more value in delineating specific subtypes of dissociative experience (e.g., FSA-dissociation), and measuring these precisely - rather than trying to capture every possible dissociative experience in one scale (unless for diagnostic purposes). That said, it may be a more user-friendly alternative to the DES.
