Researchers and educators are welcome to scales we have developed in our lab for non-commercial purposes. On a cautionary note, we point out that these scales were originally designed to assess individual differences rather than subtle within-individual changes in behavior over time. Thus, we do not know whether they are valid indicators of pre- to post-change as a consequence of interventions.


Our scales are copyrighted and cannot be published or used for commercial purposes or wide public distribution. Journalists and book authors should therefore not reproduce our scales nor any part of them.
