Even well before I came into the mental health arena I was fascinated by how it is that we scale and measure thoughts and feelings. This page takes you to some of my work in this area.

Other things and crosslinkages

  • As noted above, my main success in this area has been as a co-founder of the CORE system.  That’s more than just its instruments and measures and I maintain the CORE system web site at:
  • I did quite a lot of the early work checking the psychometrics of PSYCHLOPS a hybrid measure with one nomothetic scaling question and three user-generated questions about problems and their impact.  I strongly recommend PSYCHLOPS as a complement to nomothetic mental health change measures though I’m not impressed by the common tendency to frame nomothetic and user-generated measures as competitors or polar opposites; to my mind they are complementaries, each addressing rather different questions.  If we and our clients have the time, I believe we should all be using one at least one nomothetic and at least one user generated or idiographic measure in parallel (though not necessarily to exactly the same rhythm).
  • I have intermittently worked with, and about, repertory grids.  I’ve done much less than I would have liked to but will be working more on that in the future so these have their own heading as well nesting here and they’re an example within what I call “rigorous idiography“, another area I hope to be returning to and developing.
