"Hi Stephane: One potential problem I see with re-scaling your measures (regardless of the maths you use) is that the psychopathy scales in your sample may actually not measure the exact same construct. For example, different psychopathy…"

"Thanks David. If at all possible, we would very much appreciate if someone else on the forum could provide their views on the use of summary scores (M/SD). Thank you. Best wishes, Stephane"

"I don't think that is necessary to be effective. I believe that it can be used to put summary scores (M/SD) onto a single metric as well, but I would also like to hear any other members weigh in before endorsing that as an official…"

"Hi Stephanie, Great question! It's a big problem, because there is never agreement on a single best standard measure for any construct in behavioral science. I think you may be helped by converting all the scores from across studies that use…"

Meta-regression: How to create one measure based on different scales

Hello, I hope you will be able to shed some lights on an issue my postdoc and I are facing in the context of a meta-analysis we are currently working on. The meta-analysis will focus on structural magnetic resonance imaging studies that have compared brain grey matter volume of youths with conduct disorder and controls. Beside the standard group comparison (conduct disorder vs controls), we would like to investigate in a dimensional way (i.e., meta-regression as described here…See More

Good Day,

How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on:(frankkwabena99@gmail.com ) for the full details.
Have a nice day
Thanks God bless.


Frank.
