Hi all,
I'm teaching my students how to reverse score and conduct the various indices of reliability and validity. I must say this is incredibly easy and a joy to teach in jamovi! The heatmap of correlations is simply a godsend for demonstrating the effects of not reverse-scoring those items that are in need of this. Kudos!
However, I was wondering would it be possible to add in a feature for reliability analysis - namely the average inter-item correlation? Unless I'm very much mistaken, I can't see it? Including it so that it is automatically spat out with the heatmap would be great. At the moment I'm telling students to calculate this manually in Excel. Not a terribly difficult step I admit, but one that introduces an outside program that may not be needed....
Keep up the great work,
Paul

hi paul,
create an issue in our gh tracker: https://github.com/jamovi/jamovi/issues
and we'll see what we can do
cheers

Hi jonathon,
Thanks for the response - I've done just that!

Re: Average inter-item correlation?
Hello, I found it.
CFA, then Model Fit, then Fit measures and there is AIC and BIC.
Saludos!

Re: Average inter-item correlation?
Hiya - thanks for the suggestion, but I think this refers to the Akaike Information Criterion (a measure of fit) rather than the average inter-item correlation I was looking for.
I can see that this feature exists in JASP so it is possible. If I knew anything about programming I'd give it a bash myself

Re: Average inter-item correlation?
Hi Bobafett
You can check the snowRMM module within jamovi library to find AIC, BIC, and CAIC statistics for model fit.

Re: Average inter-item correlation?
Hi Jonathon - just wondering if you & the team have managed to take a look into this request to calculate the average inter-item correlation as part of the reliability analysis suite? I did create an issue on the github tracker (https://github.com/jamovi/jamovi/issues/1060) but I'm not particularly familiar with how that set-up works...
Cheers
Paul
